How to get the content between the specific string using PHP

Example string: This is testing string with \title{test} tags.

If I want to get the content between the parenthesis or brackets I can use below mentioned code.

$text = '[This] is a [test] string, [eat] my [shorts].';
preg_match_all("/\[[^\]]*\]/", $text, $matches);
var_dump($matches[0]);

If I want to extract the words between "\title{" and "}",what would be the exact regex?
I tried this code by replacing "[ ]" with "\title{" "}" but failed.

$text = '[This] is a [test] string, [eat] my [shorts].';
preg_match_all("/\\title{[^\]]*\}/", $text, $matches);
var_dump($matches[0]);
