_deep_replace( string|array $search, string $subject )

Perform a deep string replace operation to ensure the values in $search are no longer present


Description

Repeats the replacement operation until it no longer replaces anything so as to remove "nested" values e.g. $subject = ‘%0%0%0DDD’, $search =’%0D’, $result =” rather than the ‘%0%0DD’ that str_replace would return

(string|array) (Required) The value being searched for, otherwise known as the needle. An array may be used to designate multiple needles.

$subject

(string) (Required) The string being searched and replaced on, otherwise known as the haystack.
