i want to develop for linux. i come from a php background.
is there a standard library that i can include for common tasks like converting strings to lowercase (strtolower), searching through arrays for particular values (in_array), working with substrings, etc. These must be really standard functions - surely i can save myself the time of having to rewrite them.
also, is there any searchable documentation like php.net's firefox search extension? i've got the one for cplusplus.com, but it'd be really useful to see a list of all of the available functions/methods i can use.
