我有一个像这样的html(它的flash for flash player):

var flashvars =
            {
                'autoplay'          : autoplay,
                'autoreplay'        : 'false',
                'start'             : '',
                'hideLinkPane'      : 'true',
                'disable_sharebar'  : 'true',
                'disablePauseroll'  : disablePauseroll,
                'video_url'         : encodeURIComponent('WQFuk9Py2VC3jsCrPDJ69xtsj33MiXAElBzQw3TSHqOOyDYL0vRJELrB1hTTW3NG0A54kE2FVueuHMkQd8JveYb92eV+dYH4IUrrvJdP5Of9HGi+5i6GT11nL0dAv/ecyP4sB0jM8rVZzyS8imLarvPUvPuFPvvB8nwYXZ2ZKon4IPjmtC8SPftaw0PSuZKMg735hLCraeAE3lMQbRwiY7yMHKmUHDALG1Ky+HBDiK20vAGEIMwzPwKZmhbBXRGiHzEiXiRk4JgaVyp6N66EALao7VOE7UTzJLs='),
                'encrypted'         : 'true',
                'video_title'       : "some cool vids title here",
                'embed_js'          : "",
                'prerollRepeat'     : "false"
            };

如何使用preg_match提取video_title的值,使其成为:

echo $ videoTitle;

将输出:这里有一些很酷的视频标题

并且对于video_url将输出:

WQFuk9Py2VC3jsCrPDJ69xtsj33MiXAElBzQw3TSHqOOyDYL0vRJELrB1hTTW3NG0A54kE2FVueuHMkQd8JveYb92eV + dYH4IUrrvJdP5Of9HGi + 5i6GT11nL0dAv / ecyP4sB0jM8rVZzyS8imLarvPUvPuFPvvB8nwYXZ2ZKon4IPjmtC8SPftaw0PSuZKMg735hLCraeAE3lMQbRwiY7yMHKmUHDALG1Ky + HBDiK20vAGEIMwzPwKZmhbBXRGiHzEiXiRk4JgaVyp6N66EALao7VOE7UTzJLs =

我的php看起来像这样:

$pagex = $this->page;
$patternx = '/("video_title":")(.*?)(")/i';
if(preg_match($patternx,$pagex,$arx)){  
    $key = $arx[2];
}               


$page = $this->page;
$pattern = '/("video_url":")(.*?)(")/i';
if(preg_match($pattern,$page,$ar)){ 
$link = $ar[2];
}

它不起作用。它没有显示任何内容。

$string = "'disablePauseroll'  : disablePauseroll,
            'video_url'         : encodeURIComponent('WQFuk9Py2VC3jsCrPDJ69xtsj33MiXAElBzQw3TSHqOOyDYL0vRJELrB1hTTW3NG0A54kE2FVueuHMkQd8JveYb92eV+dYH4IUrrvJdP5Of9HGi+5i6GT11nL0dAv/ecyP4sB0jM8rVZzyS8imLarvPUvPuFPvvB8nwYXZ2ZKon4IPjmtC8SPftaw0PSuZKMg735hLCraeAE3lMQbRwiY7yMHKmUHDALG1Ky+HBDiK20vAGEIMwzPwKZmhbBXRGiHzEiXiRk4JgaVyp6N66EALao7VOE7UTzJLs='),
            'encrypted'         : 'true',
            'video_title'       : \"some cool vids title here\",";

preg_match("/encodeURIComponent\('([^']+)/", $string, $match);

echo $match[1]; // URL

preg_match('/video_title[^"]+"([^"]+)/', $string, $match);

echo $match[1]; // Title

这将在'中的encodeURIComponent()引号之间提取文本字符串,第二个将在"

video_title引号中提取文本

答案 1 :(得分:0)

对于video_title(允许标题中的转义"):

'video_title'\s*:\s*"(.*?)*(?<!\\)"

在PHP中:

$pattern='\'video_title\'\s*:\s*"(.*?)*(?<!\\)"';

对于网址:

'video_url'\s*:\s*encodeURIComponent\('([^']*)'\)

$pattern='\'video_url\'\s*:\s*encodeURIComponent\(\'([^\']*)\'\)';
