The preg_replace function performs the search and replacement of a regular expression.

Grammar

Mixed preg_replace (mixed $pattern, mixed $replacement, mixed $subject [, int $limit =-1 [, int & $count]])

Search for parts of subject that match pattern and replace them with replacement.

Parameter description:

Pattern: the pattern to search for, which can be a string or an array of strings.

Replacement: the string or array of strings used for replacement.

Subject: the target string or array of strings to search for replacement.

$limit: optionally, the maximum number of replaceable times per subject string for each pattern. The default is-1 (unlimited).

$count: optional, the number of times the replacement is executed.

Return value

If subject is an array, preg_replace () returns an array and in other cases a string.

If the match is found, the replaced subject is returned, and in other cases, the unchanged subject is returned. If an error occurs, return NULL.
