您要使用
preg_match_all()。这就是代码中的样子。实际函数返回找到的项目数，但
$matches数组将保存结果：
<?php$string = "/brown fox jumped [0-9]/";$paragraph = "The brown fox jumped 1 time over the fence. The green fox did not. Then the brown fox jumped 2 times over the fence";if (preg_match_all($string, $paragraph, &$matches)) { echo count($matches[0]) . " matches found";}else { echo "match NOT found";}?>将输出：
找到2个匹配项
