根据某些值排序网址[关闭]

Question

I have array of urls stored. Every url has some format. I need to sort the urls array. Like

https://s3.amazonaws.com/photos/1358086239.jpg?response-content-type=image%2Fjpeg&AWSAccessKeyId=AKIAI2U3TRTNGXNCQHYQ&Expires=1359636889&Signature=l9GnekYT0wK9AznkPWWjBuCRgBY%3D
https://s3.amazonaws.com/photos/1358066630.jpg?response-content-type=image%2Fjpeg&AWSAccessKeyId=AKIAI2U3TRTNGXNCQHYQ&Expires=1359636889&Signature=l9GnekYT0wK9AznkPWWjBuCRgBY%3D

These urls are reutned by amazon S3 PHP SDK get_object_url method.

I have 1000 of these urls but i want to sort these urls based on 1358086239.jpg value this value is everytime an integer value and i want to sort urls in Asc order based on this value.

How can i sort these urls array. i tried using php builtin function ksort() But it did not helped.

Try this (fixed):

$urls = array(
'https://s3.amazonaws.com/photos/1358086239.jpg?response-content-type=image%2Fjpeg&AWSAccessKeyId=AKIAI2U3TRTNGXNCQHYQ&Expires=1359636889&Signature=l9GnekYT0wK9AznkPWWjBuCRgBY%3D',
'https://s3.amazonaws.com/photos/1358066630.jpg?response-content-type=image%2Fjpeg&AWSAccessKeyId=AKIAI2U3TRTNGXNCQHYQ&Expires=1359636889&Signature=l9GnekYT0wK9AznkPWWjBuCRgBY%3D',
);


$list = array();
foreach ($urls as $v) {
   $tmp = explode('https://s3.amazonaws.com/photos/', $v);
   $tmp = explode('.jpg?response-content', $tmp[1]);

   $list[$tmp[0]] = $v;
} 

ksort($list);

var_dump($list);
