$char = "<div>11111</div><div>22222</div><div>33333</div>";preg_match_all("|<div>(.*)</div>|U", $char, $out,PREG_PATTERN_ORDER);echo $out[0][0];echo $out[0][1];echo $out[0][2];

上面这段代码可以获取字符串之间的值，但我要的效果是

我不知道字符串里有多少个

nnnnn

,我想获取所有div之间的所有值并且随机打乱顺序
比如字符串"

11111

22222

33333

44444

";
我想得到的结果是：

22222

44444

33333

11111

麻烦知道的高手直接给完整代码，谢谢了

回复讨论(解决方案)

补充：div之间有中文字符

$char = "<div>11111</div><div>22222</div><div>33333</div>";$ary = explode('<div>', $char);shuffle($ary);foreach($ary as $v){	echo '<div>'.$v;}

Copy after login

$char = "

11111

22222

33333

";
$ary = explode('

', $char);
shuffle($ary);
foreach($ary as $v)
{
if($v!=""){
echo '

'.$v;
}
}
楼上的加个判断值不为空更好点，数组后面会多循环一次，后面会多带个

谢谢楼上的两位大哥，这是一个循环
那怎么把这个值重新放到字符串里
比如$char1 = ''

代码应当怎么写，小弟不怎么懂php的，再麻烦下，谢谢了

$char = "<div>11111</div><div>22222</div><div>33333</div>";preg_match_all("|<div>(.*)</div>|U", $char, $out,PREG_PATTERN_ORDER);shuffle($out[0]);$s= join('',$out[0]);echo $s;

Copy after login

靠

用5楼的代码

$char = "<div>11111</div><div>22222</div><div>33333</div>";preg_match_all("|<div>(.*)</div>|U", $char, $out,PREG_PATTERN_ORDER);shuffle($out[0]);$char= join('',$out[0]);echo $char;

Copy after login
