preg_match 来自 jwplayer 的文件 url

Question

我使用简单的 HTML DOM 解析器从页面中获取 html。

现在我想从 <script></script> 标签中抓取文件 URL。这是我得到的：

<script type="text/javascript">
    jwplayer("ContainerFlashPlayer").setup({
        'autostart': 'true',
        'primary': 'html5',
        'flashplayer': '/images/embed/player.5.10.swf',
        'file':'/zxdfgdfr44444/afrah/Basem_elkerbelay/selawat/guivvahpasjp.mp3',
        'duration': '356.64975',
        'image': '/images/flashimg.png',
        'volume': '75',
        'height': '240',
        'width': '330',
        'controlbar': 'bottom',
        'stretching': 'fill',
        'skin': '/images/embed/skin/shiavoice1.2.zip'
    }); 

</script>

现在我想获取文件url。我该怎么做？

你可以做...

<?php
$string = "jwplayer(\"ContainerFlashPlayer\").setup({

 'autostart': 'true',
 'primary': 'html5',
 'flashplayer': '/images/embed/player.5.10.swf',
 'file':'/zxdfgdfr44444/afrah/Basem_elkerbelay/selawat/guivvahpasjp.mp3',
 'duration': '356.64975',
 'image': '/images/flashimg.png',
 'volume': '75',
 'height': '240',
 'width': '330',
 'controlbar': 'bottom',
 'stretching': 'fill',
'skin': '/images/embed/skin/shiavoice1.2.zip' 

});";
preg_match("~^\s*'file'\s*:\s*'(.*?)',?\s*$~m", $string, $file);
echo $file[1];

输出：

/zxdfgdfr44444/afrah/Basem_elkerbelay/selawat/guivvahpasjp.mp3

这个正则表达式是什么意思？

^ Start of the line

\s* any number of whitespace characters

Search for the following actual text 'file'

Again any number of whitespace characters with a colon separating it \s*:\s*

A single quote then everything inbetween that and the next single quote '(.*?)'

An optional comma, optional white space and then the end of the line ,?\s*$

The m after the closing delimiter is so the regex searches each line as its own line.
