做過好多抓取別家網(wǎng)站內(nèi)容的產(chǎn)品，習慣了使用方便快捷的file_get_contents函數(shù)，但是總是會遇到獲取失敗的問題，盡管按照手冊中的例子設置了超時，可多數(shù)時候不會奏效：

復制代碼 代碼如下:

$config['context'] = stream_context_create(array(‘http' => array(‘method' => “GET”,
'timeout' => 5//這個超時時間不穩(wěn)定，經(jīng)常不奏效
)
));

復制代碼 代碼如下:

<span>function</span> curl_file_get_contents<span>(</span><span>$durl</span><span>)</span><span>{</span>
<span>$ch</span> <span>=</span> <span>curl_init</span><span>(</span><span>)</span><span>;</span>
