I like Perl, but I hated being forced to always use regexps to do what I considered to be basic, simple string manipulation.
for something things, Perl is still great, and it has a ton of pre-written modules available to allow you to do strange and weird things, plus those modules are easily added and removed from the server they are on.
But, PHP has simpler syntax, and if what you want to do is already a built-in like pdf and image creation, or LDAP access, database access, etc... then php is a nicer choice because I believe it is easier to code in and makes more readable code.
