php curl

使用php curl更改页面信息

/*$curlobj = curl_init();//初始化
curl_setopt($curlobj,CURLOPT_URL,"http://www.baidu.com");  //设置访问页面的url
curl_setopt($curlobj,CURLOPT_RETURNTRANSFER,true);     //执行后不直接打印出来
$output = curl_exec($curlobj);                          //执行
curl_close($curlobj);                                       //关闭curl
echo str_replace("百度","DLL",$output);*/

使用curl获取图片信息

header("Content-type: text/html; charset=utf-8");
@header('Content-type:image/jpg');
$ch = curl_init();
$url="http://ww1.sinaimg.cn/mw690/78f2cc43jw1f2vtybda98j206y046t8y.jpg";
curl_setopt($ch,CURLOPT_URL,$url);
curl_setopt($ch,CURLOPT_RETURNTRANSFER,1);$output = curl_exec($ch);
$info = curl_getinfo($ch);file_put_contents("abc.jpg",$output);
curl_close($ch);

使用curl模拟post表单，上传文件

$url = "http://localhost/phpcurl/out.php";
$post_data = array("name" => "gewenrui","password" =>"123"
);
$ch = curl_init();
curl_setopt($ch,CURLOPT_URL,$url);
curl_setopt($ch,CURLOPT_RETURNTRANSFER,1);
curl_setopt($ch,CURLOPT_POST,1);
curl_setopt($ch,CURLOPT_POSTFIELDS,$post_data);
curl_setopt($ch,CURLOPT_TIMEOUT,10);$output = curl_exec($ch);$info = curl_getinfo($ch);
//echo '获取'.$info['url'].'耗时'.$info['total_time'].'秒'.$info['request_size'];curl_close($ch);echo $output;上传文件
$url = "http://localhost/phpcurl/out.php";
$post_data = array("fool"  => "bar",//上传文件此处需要添加@符号"upload" => "@abc.jpg"
);$ch = curl_init();
curl_setopt($ch,CURLOPT_URL,$url);
curl_setopt($ch,CURLOPT_RETURNTRANSFER,1);
curl_setopt($ch,CURLOPT_POST,1);
curl_setopt($ch,CURLOPT_POSTFIELDS,$post_data);
$output = curl_exec($ch);
curl_close($ch);
echo $output;

使用curl实现批处理 j

<?php
header("Content-type: text/html; charset=utf-8");
//创建两个curl资源
$ch1 = curl_init();
$ch2 = curl_init();$url1="http://www.baidu.com";
$url2="http://www.qq.com";
curl_setopt($ch1,CURLOPT_URL,$url1);
curl_setopt($ch1,CURLOPT_HEADER,0);
curl_setopt($ch2,CURLOPT_URL,$url2);
curl_setopt($ch2,CURLOPT_HEADER,0);//创建curl批处理句柄
$mh = curl_multi_init();//加上前面两个资源句柄
curl_multi_add_handle($mh,$ch1);
curl_multi_add_handle($mh,$ch2);
//预订一个状态变量
$active =  null;do{$mrc = curl_multi_exec($mh,$active);}while($mrc == CURLM_CALL_MULTI_PERFORM);
//循环调用curl_multi_exec(),它返回一个状态值,当这个值等于常量curlm_call_multi_perform的时候工作没有处理完毕
while($active && $mrc ==CURLM_OK){if(curl_multi_select($mh)!=-1){do{$mrc = curl_multi_exec($mh,$active);}while($mrc = CURLM_CALL_MULTI_PERFORM);}
}
//关闭各个句柄
curl_multi_remove_handle($mh,$ch1);curl_multi_remove_handle($mh,$ch2);curl_multi_close($mh);
