PHP Curl不存储json_encoded回显数据 [英] PHP Curl not storing json_encoded echoed data

问题描述

有人可以存储来自Curl脚本的回显结果。

Does anyone no if it is possible to store echoed results from a Curl script.

脚本示例已提交到：

\\some code to generate images using imagick and the post variables

$array = array(1,2,3,4,5,6,7,8,9);
$result = json_encode($array);
echo $result;

卷曲示例：

$id = 1;
$champ = array("product" => "1","id"=> $id,"occasion"=> $o,"field1" => "1991","field2" => "test","field3" =>"test1","field4" => "test2","field5" =>"test3","field6" =>"test4","field7" =>"test5","field8" =>"test6","test7");
foreach($champ as $key => $data){
    $field_string .= $key."=".$data."&";
}
rtrim($field_string, "&");

$url = "http://www.test.com/website/script.php";
$ch = curl_init();
curl_setopt($ch,CURLOPT_URL,$url);
curl_setopt($ch,CURLOPT_POST, count($champ));
curl_setopt($ch,CURLOPT_POSTFIELDS, $field_string);
curl_setopt($ch, CURLOPT_RETURNTRANSFER, FALSE);
$result = curl_exec($ch);
$array = json_decode($result);
curl_close($ch);
var_dump($array);

如果i var_dump（$ result）得到一个bool（true），所以我知道脚本

If i var_dump($result) i get a bool(true) so i know that the script has executed correctly and the output shows on screen however i don't seem to be able to store the information into a variable to process.

提前感谢您的建议

推荐答案

如 curl_exec文档说：

curl_exec() returns TRUE on success or FALSE on failure.
However, if the CURLOPT_RETURNTRANSFER option is set,
it will return the result on success, FALSE on failure.

在您的情况下，关闭 CURLOPT_RETURNTRANSFER
打开它

In your case you turn CURLOPT_RETURNTRANSFER off. Turn it on by

curl_setopt($ch, CURLOPT_RETURNTRANSFER, TRUE);

并再次检查$结果。

注意：如果数据包含& 字符，那么使用foreach循环和rtrim（）构建请求可能会损坏它。

Note: building a request using foreach loop and rtrim() you may damage it if your data contains & character.

只需使用 http_build_query（）与您的 $ champ ：

curl_setopt($ch,CURLOPT_POSTFIELDS, http_build_query($champ));
