除了转义的括号外,您还需要添加捕获括号.
You just need to add capturing parenthesis, in addition to your escaped parenthesis.
<?php
$in = "hello (world), my name (is andrew) and my number is (845) 235-0184";
preg_match_all('/\(([A-Za-z0-9 ]+?)\)/', $in, $out);
print_r($out[1]);
?>
这将输出:
Array ( [0] => world [1] => is andrew [2] => 845 )
