Function List
Probably the biggest problem with PHP is its inconsistency. Some function names use underscores, some don't. Some are of the form "verb object" and some are "object verb". Some use "2" instead of "to". The side sections of the cheat sheet list many of the most commonly used functions in PHP and are there to provide a quick reference to check function names.
SuperGlobals
In PHP, SuperGlobals are available at any point in a script, and allow access to data from the user and session date, as well as information about server settings and environmental data. This section contains a list of SuperGlobal variable names.
Date Formatting
There are, as I'm sure you are aware, a huge number of options when it comes to date formatting, and there are few people who remember all of them. This section of the cheat sheet lists the various options, followed by a description, and an example where appropriate.
Regular Expression Syntax
Many people have trouble with regular expressions, and the first step to coming to grips with them is to become familiar with the various symbols used in regular expressions and their meaning. This section lists these symbols and describes their meaning.
PCRE Modifiers
"PCRE" stands for "Perl Compatible Regular Expressions". In PHP, this refers to functions like "preg_replace" and "preg_split". The patterns used in these functions can have modifiers applied to them, and this section list those modifiers and what they do.
Function Argument Orders
One of the other major inconsistencies in PHP is function argument ordering. Functions that are very very similar often completely opposite ordering of arguments. This section simply lists a few of the common ones people are sometimes confused by, or that people find easy to forget.
fopen() Modes
fopen() is a widely used function and has several modes in which it can operate, depending on whether you want to read or write to a file, and what you want to do with data already in that file. This section lists those modes and what each does.
So now that you know what it does, please feel free to print out the PHP cheat sheet:
Please note: If you wish to link to the PHP cheat sheet from elsewhere, please link to this page so others find the description, rather than linking directly to the sheet.
And finally, if you like the cheat sheets, and want to say thanks, I do have an Amazon Wishlist. Thankyou very much to those who have already hunted it down and sent me something nice - I'm very grateful!
