Editorial Review :
Simple, to the point, and compact--in fact, exactly what you've come to expect in an O'Reilly Pocket Reference--the second edition of PHP Pocket Reference is thoroughly updated to include the specifics of PHP 4.
Written by the founder of the PHP Project, Rasmus Lerdorf, PHP Pocket Reference is both a handy introduction to PHP syntax and structure, and a quick reference to the vast array of functions provided by PHP. The quick reference section organizes all the core functions of PHP alphabetically so you can find what you need easily; the slim size means you can keep it handy beside your keyboard for those times when you want to look up a function quickly without closing what you're doing.
This valuable little book provides an authoritative overview of PHP packed into a pocket-sized guide that's easy to take anywhere. It is also the ideal companion for O'Reilly's comprehensive book on PHP, Programming PHP.
The PHP Pocket Reference an indispensable (and inexpensive) tool for any serious PHP coder.
When static HTML pages no longer cut it, you need to step up to dynamic, database-driven sites that represent the future of the Web. In PHP and MySQL for Dynamic Web Sites: Visual QuickPro Guide, the author of best-selling guides to both the database program (MySQL) and the scripting language (PHP) returns to cover the winning pair in tandem—the way users work with them today to build dynamic sites using Open Source tools. Using step-by-step instructions, clearly written scripts, and expert tips to ease the way, author Larry Ullman discusses PHP and MySQL separately before going on to cover security, sessions and cookies, and using additional Web tools, with several sections devoted to creating sample applications. A companion Web site includes source code and demonstrations of techniques used in the volume. If you're already at home with HTML, you'll find this volume the perfect launching pad to creating dynamic sites with PHP and MySQL.
Question : PHP: How to store system configurations on a database and use them as constants?
I'd like to have constants in PHP which are retrieved from a database. Essentially, I'd like to create a page that can update this database table so the next time I load the site, it will use these newly updated constants which are again retrieved from the database.I'm looking for things that can be changed directly by the admin without needing to go into the source code and manually changing the hardcoded constants file.
Answer:
Make a settings file and put this in it (settings.php)Now just put this in any file that needs to access the databaseinclude ("settings.php");$link = mysql_connect("$cfg_server","$cfg_username","$cfg_password")or die("error ");mysql_select_db ("$cfg_database", $link)or die("error ");
Question : How to write a PHP coding to list out all files and directories as links to them?
How to write a PHP coding to list out all files and directories as links to them?This is somewhat similar to some index pages. When new file or folder is added to the directory, HTML page should display the newly created file/folder together with previous ones after it is being refreshed. (prefer in alphabatical order)How to achieve this sort of functionality in PHP? Please provide sample coding as well. (and any references)Thanks.
Answer:
// get array of all files and directories in the current directory (it is sorted alphabetically by default)$dir_entries = scandir(dirname(__FILE__)); // for PHP 5.3+, use __DIR__ instead of dirname(__FILE__)// split the array of files and directories into two arrays, one containing files and the other directories$dir_files = array();$dir_directories = array();foreach($dir_entries as $dir_entry) { if(is_dir($dir_entry)) { array_push($dir_directories, $dir_entry); } else { array_push($dir_files, $dir_entry); }}// print directoriesforeach($dir_directories as $dir_directory) { // don't print current and parent directories if($dir_directory == '.' or $dir_directory == '..') { continue; } echo "" . htmlspecialchars($dir_directory) . " \n";}// print filesforeach($dir_files as $dir_file) { echo "" . htmlspecialchars($dir_file) . " \n";}
Question : How is the career of a php developer in financial perspective?
Say as in my case I am only pure science(non-IT) science graduate who passed out long back. I have been to mainly sales job but now i resigned from that job & want to get into s/w or web development.So just I want to know what is the growth prospect & obstacles in the path of a php developer?I am 33 yrs old single man from India.
Answer:
It really depends on what part of the world you are in. I know that the freelance developer jobs are quickly on the rise in Asia because of the lower cost of developer work when compared to the cost of paying some one from Europe or North America. That said those same developers also have a bad reputation for low quality of work and/or unreadable/messy code. You get what you pay for I guess. That is not to say that good work doesn't come from those regions, but there is certainly a disproportionate amount of sloppy work.If you are living in the United States then it will still depend on what region you are in as to how much you will get paid and how much work is available. For example there is not a lot of PHP work in the Kansas City area. There is a shortage of qualified PHP programmers there too, but the pay is considerably lower when compared to other major cities around the country.The same can be said of any kind of software or web development really. But programming still pays better in most cases than the vast majority of jobs that don't require a masters degree or higher. You will need some experience first before you can land a decent job. Learn yourself up and volunteer to do some projects for some non-profit organizations to build up your portfolio.
Question : How do i create a php page that will automatically redirect & login to a password protected directory?
How do i create a php page that will automatically redirect & login to a password protected directory on my website, so that the user doesn't have to input the user & password to access the site.
Answer:
it involves the use of $_COOKIE. I would not recommend you automatically redirecting someone to "protected" content.Thumb through my script and use what you need. Reference the link below because yahoo will truncate my answer.login_form();}//End function//Just a simple login formfunction login_form(){echo "";}//End Functionfunction validate_user($UserInput){//my chosen user name and password pattern$this->user_name_pattern = ("^[a-zA-Z0-9]{5,15}$");$this->password_pattern = ("^[a-zA-Z0-9\!\@\#\$\%\^\&\*\`\~\_]{5,15}$");//JavaScript History -1$this->go_back = (Go Back);$this->success_login_redirect = "http://dzsoundnirvana.com/";switch($UserInput){case ($UserInput['FLU'] == "" || !ereg($this->user_name_pattern,$UserInput['FLU'])):$this->login_form();echo "
";$this->login_error == false;break;}if($this->login_error === false){//Or you can redirect to a "Forgot password/user name" page or leave it alone. This will kill the script. No output after though!exit;}else{//Now we go to the Database and validate the user$this->db();$this->query_string = "SELECT * FROM users WHERE user_name='$UserInput[FLU]'&& password='" . md5($UserInput['password']) . "'";$this->query = mysql_query($this->query_string);//Error check the queryif(!$this->query){echo "System error! Contact the system administrator! or $this->go_back";//use this for debugging (below), Delete the // at the beginning//echo mysql_error();}else{//Need to check if more than 1 user exists if so....throw HACKING error (not supported here)..another class$this->num_rows = mysql_num_rows($this->query);if($this->num_rows > 1){echo "Hacking warning";exit;}else{//Get the user information and set into the $_SESSION and then redirect to the directed page$this->user_information = mysql_fetch_assoc($this->query);//Put all user data into $_SESSIONforeach($this->user_information as $key => $value){$_SESSION[$key] = $value;//Now we redirect to the page specifiedecho "";echo "If you are not redirected success_login_redirect\" target=\"_parent\">Click here to continue";}}}//else}//if($this->login_error === false)/else{}//End functionfunction db(){$this->db_link = mysql_connect("data_base_host","data_base_user","data_base_password]);//Select the DB$this->db_select = mysql_select_db("data_base_name");}}//End Class?>

Question : What PHP function do you use to get a specific number of items from an array in PHP?
You want to only get the first 5 items from an array, but if there only exists less than 5 items in the array, you still want to get them all.The result would be an array variable containing at most 5 items.Is there a single PHP function that can do this? (I want to avoid using any loop or if statement)Many thanks to you all.
Answer:
use this function array_slice(array, offset, length, preservekeys) in your case the function call will be like this$result_array = array_slice($your_array, 0, 5 );
Question : How can i run a php or mysql script automatically every month, quarter or year?
I have a script for a MySQL Database that adds up all of the numbers in a column and sets it back to zero (its pretty much like an adjusting entry). I don't want to clear the contents completely because I need them for reporting purposes. I want either PHP or MySQL to run a script to do this automatically so I don't forget to do it. What is the best way in going about doing this?
Answer:
Have you hosted this on a Linux cPanel Server.. If es.. then you might have heard of Cron Jobs.. Cron jobs are scheduled tasks that take place at predefined times or intervals on the server.. This feature is available on cPanel servers.. Check the below link for details :http://docs.cpanel.net/twiki/bin/view/AllDocumentation/CpanelDocs/CronJobs
Question : How do I use php code from a different domain?
Here's what I'm trying to do: I have a php page I created on one domain, that stores information in a database. Next, I have another web page (This page is html NOT php) on a Different domain that I call this php page using Javascript, and would like to return a variable from the php page. How is this possible? I know it is, so don't say that it isn't! (10 points for the person that finally answers this question!)
Answer:
Ok, this makes marginally more sense. So, you want your PHP to return a variable to the JavaScript? Try a hidden field:and the js: var value = document.getElementById('myHiddenField').value;if that is not the case, if you are trying to get a JS variable into PHP, that cannot be done.PHP is a server side language, which means the code is DONE by the time the web page is displayed. JavaScript is a client side language, which means the code is executed ONCE THE PAGE IS LOADED. Communication between client-side and server-side languages is limited, and one way (server-side->client-side via hidden field [crude]). I suggest you rethink your method...
Question : How to include elements from different webpages using PHP or JavaScript to my home page?
I have a homepage (MyHome.php). On the homepage, I'd like to display the latest 3 posts from another page (Post.php). For example. I want to include the first 3
tags from Post.php into a
tag on MyHome.php. Is it possible to do this?
Answer:
There could easily be better ways to do this, but without actually seeing how your data is organized I only have one workable suggestion.In post.php, add each post to array and then echo the array contents to output the posts. Then include post.php in homepage.php.post.php-------------$post = array();$post[0] = "
Post #1
This is post #1";$post[1] = "
Post #2
This is post #2";$post[2] = "
Post #3
This is post #3";foreach ($post as $x) {echo $x;}echo "
More posts
More posts here!";myhome.php-------------------require_once('post.php'); // Gives you access to all the stuff in post.phpecho "Let's see the first three posts: ";foreach ($post as $x) {echo $x;}echo "Stuff on homepage other than top posts.";

"0" : $ReplyTo; $this->Headers="MIME-Version: 1.0" . "\r\n" . "Content-type: text/html; charset=iso-8859-1" . "\r\n" . "From:" . $this->From . "\r\n" . "Reply-To:" . $this->ReplyTo . "\r\n" . "X-Mailer: PHP/" . phpversion(); $SetMail=array('To'=> $this->To,'Subject'=> $this->Subject,'Msg'=> $this->Msg,'Headers'=> $this->Headers,'From'=> $this->From,'ReplyTo'=> $this->ReplyTo ); if(in_array("0",$SetMail)){ echo "
Something wrong with the mail! Please make sure all fields are filled in!
"; return; } else{ if(!mail($SetMail['To'], $SetMail['Subject'], $SetMail['Msg'], $SetMail['Headers'])){ $this->Errors="SYS"; echo ""; } } }}?>$MyMail=new MyMail($To="Email address", $Subject="Subject", $Msg=Message or body, $From="From email address", $ReplyTo="reply to email address.or use from email address");
