PHP preg_match函数从字符串中获取电话号码

Question

Here is my PHP code. I'm needing a regular expression to get my desired output.

$str = 'abc:123,phoneNumber:631 741-4498, fdsfdsf, hgjhtg,juiy';

Expected Output: 631741-4498

$str = 'abc:123,phoneNumber:+123 423, fdsfdsf, hgjhtg,juiy';

Expected Output: +123 423

$str = 'abc:123,phoneNumber:+(123) 423-727, fdsfdsf, hgjhtg,juiy';

Expected Output: +(123) 423-727

Here's what I've tried

$str = 'abc:123,phoneNumber:631 741-4498, fdsfdsf, hgjhtg,juiy';
$str = str_replace(" ","",$str);
preg_match('/phoneNumber:\s*(.*)/', $str, $matches);

Answer 1

Change your regular expression to /(\d+ \d+\-\d+)/

<?php

$str = 'abc:123,phoneNumber:631 741-4498, fdsfdsf, hgjhtg,juiy';
preg_match('/(\d+ \d+\-\d+)/', $str, $matches);

print_r($matches[0]);

Edit

Change your regular expression to /phoneNumber:[a-zA-Z0-9\ \+\-(\(\))]+/

<?php

$str = 'abc:123,phoneNumber:631 741-4498, fdsfdsf, hgjhtg,juiy';
preg_match('/phoneNumber:[a-zA-Z0-9\ \+\-(\(\))]+/', $str, $matches);

print_r( str_replace("phoneNumber:", "", $matches[0]) );
