PHP获取URL内容并搜索字符串

在PHP中我需要获取URL(源)的内容搜索字符串"也许宝贝爱你",如果它不包含这个,那么做x.

只需阅读页面内容就像读取文件一样.PHP为您完成连接.然后只需通过正则表达式或简单的字符串比较查找字符串.

$url = 'http://my.url.com/';
$data = file_get_contents( $url );

if ( strpos( 'maybe baby love you', $data ) === false )
{

    // do something

}

//The Answer No 3 Is good But a small Mistake in the function strpos() I have correction the code bellow.

$url = 'http://my.url.com/';
$data = file_get_contents( $url );

if ( strpos($data,'maybe baby love you' ) === false )
{
    // do something
}
