Replace Comma(,) with Dot(.) RegEx php

Question

i am trying this code but i get this error: No ending delimiter '/' found

$form = " 2000,50";
$salary = preg_replace('/',', '.'/', $form); // No ending delimiter '/' found 
echo $salary;

I am not sure about the regex validation.

Answer 1

Regex is overkill for replacing just a single character. Why not just do this instead?

str_replace(',', '.', $form);

Answer 2

$salary = preg_replace('/,/', '.', $form);

But yeah, you don't really want to match a pattern but a string which is constant, so simply use str_replace().

Answer 3

You can simply use

str_replace(',','.',$form);
