在PHP中用引号括起来的“at”符号是什么意思?
问题描述:
I've got this code:
$filePath = '/blah/image.jpg';
$data_array = array(
"file_data"=>"@".$filePath,
);
the $data_array = array
construct is an array definition and "file_data"=>"@".$filePath,
specifies an array element.
The array is then used for setting up an HTTP POST request:
curl_setopt($request, CURLOPT_POSTFIELDS, $data_array);
What does "@"
in "@".$filePath
mean?
我有这段代码: p>
$ filePath = '/blah/image.jpg';
$data_array = array(
“file_data”=>“@”。$ filePath,
);
code> pre>
$ data_array = array code>构造是一个数组定义,“file_data”=>“@”。$ filePath, code>指定一个数组元素。 p> \ n
然后使用该数组设置HTTP POST请求: p>
curl_setopt($ request,CURLOPT_POSTFIELDS,$ data_array);
code> pre>
“@”中的“@” code>。$ filePath code>是什么意思? p>
div>
答
It's a literal @
sign being prepended to a string. The result is a value of @/blah/image.jpg
