Replace all occurences of char inside quotes on PHP

Question

How could I convert something like this:

\"hi (text here) and (other text)\" come (again)

To this:

\"hi \\(text here\\) and \\(         


        

Answer 1

This should do it for both single and double quotes:

$str = '"hi \(text here)" and (other text) come \'(again)\'';

$str = preg_replace_callback('`("|\').*?\1`', function ($matches) {
    return preg_replace('`(?

output

"hi \(text here\)" and (other text) come '\(again\)'

It is for PHP >= 5.3. If you have a lower version (>=5) you have to replace the anonymous function in the callback with a separate function.
