By Viral Patel on May 7, 2009 Following are list of 15 most useful PHP code snippets that a PHP developer will need at any point in his career. Few of the snippets are shared from my projects and few are taken from useful php websites from internet.
Posted April 24th, 2010 in PHP The PHP CLI (command line interface) allows basic syntax checking of a PHP file. I'll show the basic usage of this in this post and then a couple of ways to check all files in a directory, and all files recursively down the directory tree as posted by a couple of people on Twitter. Syntax checking a single PHP file from the command line The syntax for checking is like this, where the -l flag is a lower case L: If the syntax in the file is correct you will see this:
PHP PSD Reader A few weeks ago, I wrote an article about this PHP which allow you to display any Adobe PSD file on screen. Very usefull to create preview of PSDs designed for clients, for example. Download
I’ve compiled a small list of some useful code snippets which might help you when writing your PHP scripts… Email address check Checks for a valid email address using the php-email-address-validation class. Source and docs: http://code.google.com/p/php-email-address-validation/
I'll start out by explaining some of the things I don't like about PHP. If I get this all out of the way, you can get to the useful stuff. I'll use this opportunity to say something instructive about how to use the language, based on its strengths and weaknesses, though, so it's not wasted time entirely. 1. PHP's syntax is weak. There will be times this will feel limiting.
There are three operators that are complicated enough to get their own section, of which the first is the ternary operator. It is called the ternary operator because it takes three operands - a condition, a result for true, and a result for false. If that sounds like an if statement to you, you are right on the money - the ternary operator is a shorthand (albeit very hard to read) way of doing if statements. Here's an example: <?php $agestr = ( $age < 16 ) ?
As this book aims to be a complete guide to PHP, it would not be right not to list the entire selection of operators in the language, so here goes: 3.12.3.1 Arithmetic Operators If you have not used modulus since school, here's a quick refresher. To calculate $a % $b , you first perform $a / $b and then return the remainder. For example, if $a were 10 and $b were 3, $b would go into $a 3 whole times (making nine) with a remainder of 1.
