Php preg_match_all 来自 json 文档
Php preg_match_all from a json document
您好，我想在 PHP 中使用 preg_match_all 从 [=22] 中解析以下内容中的“{"id":xxxxxxxxxx,"opponent"” =] 文档。
我想获得以下 ID：0：
3043248027
3041643291
3043251372
3041727642
3042908044
3041713366
preg_match_all('/{"id":(.*),"opponent"/', $jogo, $matchesg);
foreach($matchesg[1] as $jog):
echo "<br><br>" . "jogos: " . $jog . "<br>";
endforeach;

不要使用 preg_match，最好解码 json，然后搜索密钥：
$json = json_decode('...', true);
$lists = $json['list'];
foreach($lists as $list) {
echo "<br><br>" . "jogos: " . $list['id']. "<br>";
}
也许正则表达式不是最佳选择，但重要的是再次做出选择。通过使用带 (\d+) 的捕获组专门捕获数字，您可以轻松获得所需的值。使用 (.*) 本质上是要获取所有你绝对不想要的东西。
$re = "/\"id\":(\d+),\"opponent\"/m";
preg_match_all($re, $str, $matches);

非常感谢。
不要使用 preg_match，最好解码 json，然后搜索密钥：
$json = json_decode('...', true);
$lists = $json['list'];
foreach($lists as $list) {
echo "<br><br>" . "jogos: " . $list['id']. "<br>";
}
也许正则表达式不是最佳选择，但重要的是再次做出选择。通过使用带 (\d+) 的捕获组专门捕获数字，您可以轻松获得所需的值。使用 (.*) 本质上是要获取所有你绝对不想要的东西。
$re = "/\"id\":(\d+),\"opponent\"/m";
preg_match_all($re, $str, $matches);
