RegEx for capturing and replacing a string with quotes

Question

I want to str_replace in a function.

Attempt

str_replace(array('(', ')', array('"', '\'')), array('\(', '\)', '["|\']'), 'hello("test")');

Desired output:

hello\(["|']test["|']\)

This would work, but not very useful:

str_replace(array('"', '\''), '["|\']', str_replace(array('(', ')'), array('\(', '\)'), 'hello("test")'));

How do I solve this problem?

Answer 1

Here, we might want to capture hello and test, then assemble what we like to have using a preg_replace:

$re = '/(.*)\("(.+)"\)/m';
$str = 'hello("test")';
$subst = "$1\([\"|']$2[\"|'\"]\)";

$result = preg_replace($re, $subst, $str);

echo $result;

Output

hello\(["|']test["|'"]\)
