Case-insensitive str_replace

Question

How do I use str_replace but to be case-insensitive when it searches for the string?

For example, suppose i want to replace ABcD with a. The resulting command would be $string=str_replace("ABcD","a",$string);. But if there is some string like "abCD" then again I have to use $string=str_replace("abCD","a",$string);.

Answer 1

Then instead of using str_replace try usingstr_ireplace Its a case insensitive version of str_replace so use it as

$string = str_ireplace("ABcD","a",$string);
