replace function js to php

replace function js to php

I am trying to change a js program to php. there is a replace function like $t = t.replace(/B/g, "b");

if i change this to php as $t = str_ireplace(/B/g, "b",$t);

it shows error about "unexpecting '/' ". how to solve this.

First, JavaScript's replace function is closest to preg_replace.

Second, if you read the docs for str_ireplace, it's case-insensitive replace, which given that you're trying to turn B into b is precisely the wrong function to use.

You can do $t = str_replace('B', 'b', $t); (simpler) or $t = preg_replace('/B/', 'b', $t); (can handle more complex situations than what you're doing).

That call to Javascript replace uses a regular expression as the search criterion.

The PHP Equivalent is preg_replace
