PHP CURL은 JQuery의 Ajax 요청 헤더를 시뮬레이션하여 _SERVER에 표시할 수 있는 매개변수를 추가합니다.

<span>function </span><span>Get</span><span>(</span><span>$url</span><span>)</span>

<span><span>{</span></span>

<span><span><span></span>$ch </span><span>= </span><span><em>curl_init</em></span><span>();
</span><span><em><span></span>curl_setopt</em></span><span>(</span><span>$ch</span><span>, </span><span><em>CURLOPT_URL</em></span><span>, </span><span>$url</span><span>);
</span><span><em><span></span>curl_setopt</em></span><span>(</span><span>$ch</span><span>, </span><span><em>CURLOPT_HEADER</em></span><span>, </span><span>0</span><span>);
</span><span><em><span></span>curl_setopt</em></span><span>(</span><span>$ch</span><span>, </span><span><em>CURLOPT_RETURNTRANSFER</em></span><span>, </span><span>1</span><span>);</span></span>

<span></span><pre class="brush:php;toolbar:false"><span><span><span></span>$HEADER </span><span>= </span><span>array</span><span>(
</span><span><span></span></span><span>'X-REQUESTED-WITH: XMLHTTPREQUEST'
</span><span><span></span>);
</span><span><em><span></span>curl_setopt</em></span><span>(</span><span>$ch</span><span>, </span><span><em>CURLOPT_HTTPHEADER</em></span><span>, </span><span>$HEADER</span><span>);
</span><span><span></span>$return </span><span>= </span><span><em>curl_exec</em></span><span>(</span><span>$ch</span><span>);
</span><span><em><span></span>curl_close</em></span><span>(</span><span>$ch</span><span>);
</span><span></span><span><span></span>return </span><span>$return</span><span>;</span></span>

<span><span>}</span></span>

<span>总结: 设置的头如: A-B-C, 在_SERVER变量中打印出来的key会变成 HTTP_A_B_C的形式.</span>
