PHP: Regex to match the following string samples

开发者 https://www.devze.com 2023-03-16 19:06 出处：网络

I\'ve been constantly attempting to adapt a perfect string matching expression for my syntax highlighter, but it\'s time to ask for help.

    }

?>

I'm looking for an expression that can successfully match all content between '' and "".

It needs to ignore all (correctly) escaped versions of themselves. (So content between '' will ignore \', and content between "" will ignore \")

It doesn't matter which one comes first.

Here are two expressions I have already tried:

"/'[^'\\\\]*(?:\\\\.[^'\\\\]*)*?'/"
"/'(.[^']*)'/"

Try this raw regex. Group 2 would contain your strings.

(['"])((?:\\\1|(?!\1).)+)\1

Since PHP isn't my language I'm not sure I escaped it correctly, but try this:

$pattern = '/([\'"])((?:\\\\\\1|(?!\\1).)+)\\1/';

This one won't catch commented code appropriately, for example:

// ' my string does not get terminated.
