string$pattern,
string$replacement,
string$string,
[string|null$options = null]
): string|false|null
Scans string for matches to pattern, then replaces the matched text with replacement.
Parameters
- pattern
-
The regular expression pattern. Multibyte characters may be used. The case will be ignored.
- replacement
-
The replacement text.
- string

The searched string.
- options

Notes
Note:
The internal encoding or the character encoding specified by mb_regex_encoding will be used as the character encoding for this function.
Warning:
Never use the e modifier when working on untrusted input. No automatic escaping will happen (as known from preg_replace). Not taking care of this will most likely create remote code execution vulnerabilities in your application.
