如何在字符串中用方括号替换引号

Question

I have this string 'My String' with square brackets eg [My String] .

At the moment I can only get the string like:

$re = '/'([^']+)'/'; $str = "'My String'"; preg_match($re, $str, $matches);

How can I get replace the qoutes using preg_replace()

Answer 1

You can use this code to replace '' with []:

<?php

$string = "blabla'My String'blabla";
echo preg_replace("/([^']*)'([^']+)'([^']*)/", '$1[$2]$3', $string);
// Output will be "blabla[My String]blabla"

preg_replace is a core php function that replace a pattern in a string
