Request URL containing $ doesn't work well with PHP - cURL #284
Description
Short Explanation
When I am generating PHP - cURL code from a postman request with URL containing a $ sign followed by a letter or underscore (for example $firstName, $_address, $LastName), then the code generated by postman doesn't work. This is because PHP treats them as variable name (but they are not variable name(s) in this case).
Example
My request URL is : -
> http://example.com/path?$filter=name eq John
The code generated by postman : -
<?php
$curl = curl_init();
curl_setopt_array($curl, array(
CURLOPT_URL => "http://example.com/path?$filter=name%20eq%20John",
CURLOPT_RETURNTRANSFER => true,
CURLOPT_ENCODING => "",
CURLOPT_MAXREDIRS => 10,
CURLOPT_TIMEOUT => 0,
CURLOPT_FOLLOWLOCATION => true,
CURLOPT_HTTP_VERSION => CURL_HTTP_VERSION_1_1,
CURLOPT_CUSTOMREQUEST => "GET",
));
$response = curl_exec($curl);
curl_close($curl);
echo $response;The above code will not work as PHP will treat $filter as a variable name. To solve this problem we need to put a \ (backslash) before $filter like this : -
<?php
$curl = curl_init();
curl_setopt_array($curl, array(
CURLOPT_URL => "http://example.com/path?\$filter=name%20eq%20John",
CURLOPT_RETURNTRANSFER => true,
CURLOPT_ENCODING => "",
CURLOPT_MAXREDIRS => 10,
CURLOPT_TIMEOUT => 0,
CURLOPT_FOLLOWLOCATION => true,
CURLOPT_HTTP_VERSION => CURL_HTTP_VERSION_1_1,
CURLOPT_CUSTOMREQUEST => "GET",
));
$response = curl_exec($curl);
curl_close($curl);
echo $response;And now it will work flawlessly.
