Perl is not being used for large projects as much as PHP. Why? Because of a number of good reasons that many Perl advocates are ignoring:
- mod_php is easier to install than mod_perl.
- PHP is easier to learn than Perl.
- PHP is fast.
- PHP is powerful. You can now use PHP at the command-line. You can even use PHP for shell scripting or to build GUIs.
- There are not as many ways of doing things in PHP as there are in Perl. This is a positive thing for PHP if you have large projects with a large team of programmers working on code for a long time.
- If you need help with PHP, you go to one source: www.php.net. If you need help with Perl, you have many different websites offering different things (like documentation, modules, articles, etc).
- PHP is open source, but better marketed than Perl.
- PHP is buzzword compliant.
I have belonged to the Perl community for some time and I don't know if anyone else is noticing this, but the same websites are always referenced when discussing large projects. These sites are etoys, Amazon, CNNSI, Slashdot, Wired, TicketMaster, and few others. How long and impressive do you think the list of sites using Java and PHP are?
