I want to remove anything between simple quotes in a string from a file:

$file = file_get_contents("myfile");
preg_replace("/(')(.)*?\1/", "", $file);

The regex works on http://regexr.com/ but has no effect in php. There are many occurrence in the file.

Is there something special about the quotes because they are from a file ? What would be the process and why is mine not working ?

Hum, if it's duplicate I'll try to find it and remove my question. – Valentin BEAULE Mar 01 '17 at 09:24

Clarifying: use `preg_replace('/(\').*?\1/', '', $file);`. You may keep the question. Also, do not use http://regexr.com/ to test PHP regex, use regex101.com or others that are PCRE regex compatible. Regex101.com also has a *code generator* section that generates the right code for you. – Wiktor Stribiżew Mar 01 '17 at 09:24
It's still not working. I'll read the post you linked me. – Valentin BEAULE Mar 01 '17 at 09:29

Not working how? Do you assign the result to the variable? `$file = preg_replace('/(\').*?\1/', '', $file);` – Wiktor Stribiżew Mar 01 '17 at 09:31
XD okay, this one was dumb. Thanks for the help, I'll now use single quotes and regex101.com. – Valentin BEAULE Mar 01 '17 at 09:36
