我有一个字符串：

我想在单词message from和/message
如果我使用以下代码：
function get_string_between($string, $start, $end){
$string = " ".$string;
$ini = strpos($string,$start);
if ($ini == 0) return "";
$ini += strlen($start);
$len = strpos($string,$end,$ini) - $ini;
return substr($string,$ini,$len);
}
$res = cleanupXML($data);
$parsed = get_string_between($res, 'message fro', "/message");
echo $parsed;
它只给出一个结果。我想在这两个词之间发生一切。我怎么能得到这个？

使用正则表达式和php正则表达式函数。
preg_match_all('/message from(.+)\/message/', $string, $variable);
它将为您提供一个包含6个元素的数组。每个元素如下所示：
message from="919788517593@s.whatsapp.net" type="text" id="jtOjHBip5NY+12"
offline="0" t="1449674223" notify="Rohitashv singhal"><br/>
rx <body>Hiiiii</body><br />
rx </message

这个怎么样？
function getBetween($content,$start,$end){
$r = explode($start, $content);
if (isset($r[1])){
$r = explode($end, $r[1]);
return $r[0];
}
return '';
}
getBetween($res, 'message fro', "/message");
答案 2 :(得分：0)
使用正则表达式和preg_match_all()：
$re = "/message from=(.*)\\/message/";
