curl_exec printing results when I don't want to
提问by Oliver Bayes-Shelton
I am using the following code:
我正在使用以下代码：
$ch = curl_init();
curl_setopt($ch, CURLOPT_URL, $url);
curl_setopt($ch, CURLOPT_TIMEOUT, 12);
$result = curl_exec($ch);
curl_close ($ch);
However it's printing the results straight away. Is it possible to put the JSON result into a variable so I can print it out when I want to?
但是它会立即打印结果。是否可以将 JSON 结果放入一个变量中，以便我可以在需要时将其打印出来？

Set CURLOPT_RETURNTRANSFERoption:
设置CURLOPT_RETURNTRANSFER选项：
// ...
curl_setopt($ch, CURLOPT_RETURNTRANSFER, TRUE);
$result = curl_exec($ch);
Per the docs:
根据文档：
CURLOPT_RETURNTRANSFER-TRUEto return the transfer as a string of the return value ofcurl_exec()instead of outputting it out directly.
CURLOPT_RETURNTRANSFER-TRUE将传输作为返回值的字符串返回，curl_exec()而不是直接输出。

Have you tried?
你有没有尝试过？
curl_setopt($ch, CURLOPT_VERBOSE, 0);
This worked for me!
这对我有用！

after php 5.1 curlwill display always result you can view in documentation. for avoid it simply use
在 php 5.1 之后curl将始终显示结果，您可以在文档中查看。为了避免它，只需使用
echo "< span style='display:none'>";
$ch = curl_init();
curl_setopt($ch, CURLOPT_URL, $url);
curl_setopt($ch, CURLOPT_TIMEOUT, 12);
$result = curl_exec($ch);
curl_close ($ch);
echo"< /span>";
