• What are All the Ways a Programmer Could use PHP to Send an Email?

  - by Alan Storm

  I'm looking for a list of built in PHP functions that a programmer could use to send an email. The obvious answer here is mail(), but I'm also looking for a list of functions someone might use to manually open a connection to an MTA, or spawn a process on the local machine which might in turn send an email using sendmail, postfix, etc. The context here is I want to scan a large, unknown codebase for code that's sending out email (because we already located a call to mail(), and that's not doing it)

• Why should I be using testing frameworks in PHP?

  - by Industrial

  Hi everyone, I have recently heard a lot of people argue about using PHP testing features like PHPunit and SimpleTest together with their IDE of choice (Eclipse for me). After googling the subject, I have still a hard time understanding the pros and cons of using these testing frameworks to speed up development. If anyone could explain this for me in a more basic level, I would really appreciate it. I am using PHP5 for the notice. Thanks a lot!

• Will the Order of my Associative Array be maintained from PHP to Javascript?

  - by Colin

  In PHP I'm running a mysql_query that has an ORDER BY clause. I'm then iterating through the results to build an associative array, with the row_id as the key. Then, I'm calling json_encode on that array and outputting the result. This page is loaded with AJAX, and defined in a Javascript variable. When I iterate through that Javascript variable, will I still have the order that was returned from the mysql_query?

• As a PHP developer thinking of making Perl a secondary strong suit, what do I need to know?

  - by Hexagon Theory

  I consider myself quite fluent in PHP and am rather familiar with nearly all of the important aspects and uses, as well as its pratfalls. This in mind, I think the major problem in taking on Perl is going to be with the syntax. Aside from this (a minor hindrance, really, as I'm rather sold on the fact that Perl's is far more readable), what are some key differences you think I should make myself aware of prior to taking on the language?

• How to compress/decompress a long query string in PHP?

  - by jodeci

  I doubt if this is encryption but I can't find a better phrase. I need to pass a long query string like this: http://test.com/test.php?key=[some_very_loooooooooooooooooooooooong_query_string] The query string contains NO sensitive information so I'm not really concerned about security in this case. It's just...well, too long and ugly. Is there a library function that can let me encode/encrypt/compress the query string into something similar to the result of a md5() (similar as in, always a 32 character string), but decode/decrypt/decompress-able?

• Is it possible to parse and apply patch files in PHP?

  - by radj

  The idea is to have a PHP script parse a given .patch file and will apply the given patch accordingly. Assume that the script has no access to command line so the script will have to do the parsing itself. Is there a library somewhere?
