Missing pcre.h when installing pecl_oauth
September 27, 2010 @ 12:58:50

If you've ever come up against an error when trying to compile the pecl_oauth package (from the PECL repository), you might take a look at this new post from Lorna Mitchell on how she solved the issue and got the compile running smoothly again.

When I tried to install from PECL, it grabbed the files, ran the configure step but stopped with an error status during make. [...] Closer inspection showed this line around the point things started to go wrong: Error [...] pcre.h: No such file or directory. I didn't have the header files for pcre installed - in ubuntu the headers are in the -dev packages.

A quick call to "aptitude" to grab and install those development libraries and she was back up and running. She's running Ubuntu, but this tip is cross-distribution - you'll just have to use the package manager (and package name) of your distribution's choice.

Padraic Brady's Blog:
PCRE Regex Word Matching "w" vs "a-zA-Z0-9_"
December 28, 2009 @ 09:41:21

Padraic Brady has posted about an issue he noticed when working with regular expressions and the "word" character type to find something that's alpha-numeric (including an underscore):

You can find the "word" generic character type used in a lot of PHP code including the Zend Framework. The problem is that the assumption above is incorrect. Now, most of the time these act identically because PHP is compiled using its own packaged PCRE library. However, I've seen more than once systems where this is not the case. Usually in some non-English capacity where additional locale support was considered necessary or standard practice.

The problem comes when PHP is compiled against a custom PCRE library, making it more locale-aware. He gives instructions on how to get this to a testable state on your environment (using an updated PREC library) and get it working for characters in French, like the accented "a" or "e".

Regular Expressions (Part1) - Basic Syntax
October 13, 2008 @ 09:35:48

PHPFreaks.com has posted part one of a series of tutorials covering some of the basics of one of the more powerful features in any language - regular expression support.

Regular expressions (which will now be referred to as "regexes") are basically pattern matching inside of text. They use special syntax and concepts in order to obtain information from a string. Many programming languages have some sort of support for regexes, because of the sheer usefulness of them. Not only can patterns be used to validate that a certain pattern exists in a string, but they can also be used to physically extract matched portions and make them usable in your PHP code.

They look at some of the basics - example structure, metacharacters, greediness as well as include a brief comparison of PCRE versus POSIX versions. The tutorial is peppered with plenty of example expressions too, giving you a good idea of what you're working towards knowing.

Antony Dovgal's Blog:
5.3 snapshots are available
February 28, 2008 @ 09:33:00

Antony Dovgal points out that Derick Rethans has added the snapshots for PHP 5.3 to the snaps.php.net website.

Short list of what you can find there: Namespaces, __callstatic() magic method, accessing static members through $foo::myFunc(), fully rewritten ini-parser with .htaccess-like user defined ini files for CGI/FastCGI, improved OpenSSL extension, PCRE 7.4, and other fixes and improvements that will never get into 5_2 branch.

He recommends teching throughly before the major release to find all of the bug before the general public does. Builds for both source and Windows systems have been posted.

PHPWACT.org:
Handling UTF-8 with PHP
January 24, 2008 @ 07:51:00

Ed Finkler has pointed out a handy resource for those trying to cope with using the UTF-8 support included in several of PHP's functions - this page on the Web Application Component Toolkit wiki.

This page is intended as a reference for functionality PHP provides which can either help with handling UTF-8 or should be regarded as a risk when used in conjunction with UTF-8 encoded strings. Further information can be found on the Internationalization (I18N) and Character Sets / Character Encoding Issues pages.

It talks about the "dangerous" functionality PHP has (issues that the language has in current functions) when using things like the PCRE extension, the string extension, the array methods, handling variables, the XML extensions (DOM and SAX), image manipulation, and URL parsing functionality.
