Convert variables to lowercase in code

[jdr0606]

I'm looking for a program to parse through a PHP file and change all variables to lowercase.

Thought I'd ask before I write one for myself.

Thanks

Yes try strtolower($str) where $str is the var passed.

Thanks, I'm aware of the strtolower function, but what I'm looking for is a program to parse through several programs that have been written where the variables have no case consistancy and I want to automate the change to all of them instead of doing it manually one variable at a time.

I think a normal word processor would do fine... just do a find and replace on the source files. Say there was $varname, $VarName, $VARNAME, $VaRnAme, $VaRNAMe. You could open them in any decent word processor, do a find and replace with the search string "$varname", and the replace string the same. It should then find all occurrences, regardless of case, and replace them with the lowercase version. Actually, that might work with PHP's own find and replace function, if you want it to be automated, but I only tried it in Word.

This is the kind of thing the Perl language was originally developed for. A single regular expression substitution run from the command line could probably do the whole thing. But this is the wrong forum... 😉
