如何使用php getStr获取html标签的“name”属性？

Question

I'm trying to find a way to get the content of this HTML attribute "name", using PHP getStr, I can't get it to work anyhow, I have already searched, but I couldn't find find something that may help me.

<input id="9d6e793e-eed2-4095-860a-41ca7f89396b.subject" maxlength="50" name="9d6e793e-eed2-4095-860a-41ca7f89396b:subject" value="" tabindex="1" class="subject required field" type="text"/>

I want to get this value into a string:

9d6e793e-eed2-4095-860a-41ca7f89396b:subject

I can get the value of a tag like this one:

<input type="hidden" name="message" value="1442814179635.Oz1LxjnxVCMMJ0QpV0wGLx4roEA="/>

With this code:

getStr($b,'name="message" value="','"');

But I can't find a way to get the attribute name of the first one?

Use regular expressions in PHP. This code should be helpful:

<?php

$str  = '<input type="hidden" name="message" value="1442814179635.Oz1LxjnxVCMMJ0QpV0wGLx4roEA="/>';

//forward slashes are the start and end delimeters
//third parameter is the array we want to fill with matches
if (preg_match('/name="([^"]+)"/', $str, $m)) {
    print $m[1];   
} else {
   //preg_match returns the number of matches found, 
   //so if here didn't match pattern
}

Output:

message
