<li class="store-item" num="3">dkjfdkjfdf</li>
<li class="store-item" num="4">dkjfdkjfdf</li>怎样用php 正则取出dkjfdkjfdf

Answer 1

$str = <<<STR
<li class="store-item" num="1">dkjfdkjfdf</li>
<li class="store-item" num="2">dkjfdkjfdf</li>
<li class="store-item" num="3">dkjfdkjfdf</li>
<li class="store-item" num="4">dkjfdkjfdf</li>
STR;
preg_match_all("/<li\s+class=\"store-item\"\s+num=[^>]*>([^<].*)<\/li>/im", $str, $matches);
var_dump($matches[1]);

Answer 2

$string='
<li class="store-item" num="1">dkjfdkjfdf</li>
<li class="store-item" num="2">dkjfdkjfdf</li>
<li class="store-item" num="3">dkjfdkjfdf</li>
<li class="store-item" num="4">dkjfdkjfdf</li>
';preg_match_all('#<li[^>]+>(.*)</li>#i',$string,$match);print_r($match[1]);

Answer 3

正则表达式为
$string='
<li class="store-item" num="1">dkjfdkjfdf</li>
<li class="store-item" num="2">dkjfdkjfdf</li>
<li class="store-item" num="3">dkjfdkjfdf</li>
<li class="store-item" num="4">dkjfdkjfdf</li>
';//注意使用正则的修正符U
preg_match_all("/<li[^>]+>(.*)<\/li>/iU",$str,$match);
var_dump($match);

Answer 4

把匹配函数中的$str改成$string

Answer 5

$string='
<li class="store-item" num="1">dkjfdkjfdf</li>
<li class="store-item" num="2">dkjfdkjfdf</li>
<li class="store-item" num="3">dkjfdkjfdf</li>
<li class="store-item" num="4">dkjfdkjfdf</li>
';preg_match_all('/<li[^>]+>([^<]*)</li>/i',$string,$match);print_r($match[1]);
