Case-insensitive str_replace()

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);
Solution

  • Use the PHP functionstr_ireplace as shown below.

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