How can one efficiently replace wildcard characters like '*' with regular expressions in PHP?

To efficiently replace wildcard characters like '*' with regular expressions in PHP, you can use the str_replace() function along with the preg_quote() function to escape the wildcard character before using it in the regular expression pattern.

$wildcard = '*';
$string = 'Replace * with regular expressions';

$escaped_wildcard = preg_quote($wildcard, '/');
$pattern = '/'.$escaped_wildcard.'/';
$replacement = 'replacement';

$result = preg_replace($pattern, $replacement, $string);

echo $result;
