PHP删除第一个div标签并保留内部内容

I am working with php,

this is my string:

<div style="color:#fff;height:10px">
 <table>some code</table>
 <div>bla bla bla</div>
</div>

I would like this output:

<table>some code</table>
<div>bla bla bla</div>

The first <div> tag with its attributes (style, id, etc...) and it closer </div> is remove from string

You can use regexp:

$new_html = preg_replace("/(^<div[^>]*>|<\/div>$)/i", "", $html);

$alldetail = '<div style="color:#fff;height:10px">
 <table>some code</table>
 <div>bla bla bla</div>
</div>';

$maindetail = str_replace('<div style="color:#fff;height:10px">','',$alldetail);
$maindetail = str_replace('</div></div>','</div>',$maindetail);

echo $maindetail;
