Question

我需要拆解一个网页,该网页有一片javascript阵列,被贴在网上javascript代码上,例如:

<script>
    var videos = new Array();
    videos[0] =  http://myvideos.com/video1.mov ; 
    videos[1] = ....
    ....
</script>

采取什么最容易的方式来处理这一问题,最终将使用这些录像带的PHP阵列?

Edit: All videos are .mov extension.

Answer 1

这比以往更为复杂,但只有这些联系才能得到,这些联系实际上是<代码>videos[0] = http://myvideos.com/video1mov;。

$tmp=str_replace(array("
","
"),  ,$original,$matches);
$pattern= /<script>s+var videos.*?((s*videos[d+] = .http://.*?;s*?)+)(.*?)</script>/ ;
$a=preg_match_all($pattern,$tmp,$matches);
unset($tmp);

if (!$a) die("no matches");

$pattern="/videos[d+] = /";
$matches=preg_split($pattern,$matches[1][0]);

$final=array();
while(sizeof($matches)>0) {
  $match=trim(array_shift($matches));
  if ($match==  ) continue;
  $final[]=substr($match,1,-2);
}
unset($matches);

print_r($final);

在该次会议上,在履行机构提出反馈意见后,简化版本如下:

$original=file_get_contents($url);
$pattern= /http://.*?.mov/ ;
$a=preg_match_all($pattern,$original,$matches);
if (!$a) die("no matches");
print_r($matches[0]);

Answer 2

You can scrape this by reading the page with a file_get_contents then retrieve the urls with a regex. This is the simplest way i know, especially if you know the file extensions for your videos. Exemple:

<?php
$file = file_get_contents( http://google.com );
$pattern =  /http://([a-zA-Z0-9-.]+.[fr|com]+)/i ;
preg_match_all($pattern, $file, $matches);
var_dump($matches);
