4. The cause is initially derived, the value of the variable $otherpattern is “province/state caused by “/” caused by “/”. Reference:Regular expression special characters are: . \ + * ?[ ^ ]$ ( ) { } = ! < > | : – # . Note / is not a regular expression special character. The code is adjusted as follows
foreach ($otherPatterns as $otherPattern) {
if ($originalDescription == $description) {
$description = preg_replace('/(' . preg_quote($startPattern, '/') . ')[\s\S]*' . $pattern . '[\s\S]*(,' . preg_quote($otherPattern, '/') . ')/', '$1***' . $pattern . '***,' . $otherPattern, $description);
}
}
5. No more errors are reported, and the replaced format is: the mailing address has been changed from *** to ***. in line with expectations. as shown in Figure 2
