translating curl request to php -

i trying use , api, curl request below works on command line:

curl 'https://subdomain.test.domain.com/api/v1/users/4508184'  -x put  -f 'user[avatar][url]= http://domain.com/canvas/avatar.jpg'  -h "authorization: bearer tokenxxxxxxxxyyyyyyy" 

here have translated code above php, although request being sent not working because says "token invalid". 100% sure token working , correct presume there in code

$curl = curl_init(); curl_setopt_array($curl, array( curlopt_url => "{$baseurl}{$userid}",  curlopt_customrequest => 'put',  // -x curlopt_postfields => 'user[avatar][url]=http://domain/canvas/avatar.jpg', // -f curlopt_httpheader => $header // -h )); $result = curl_exec($curl); curl_close($curl); 

thank you

saw in $header (single quotes) work:

$header = "authorization: bearer tokenxxxxxyyyyy";  $curl = curl_init(); curl_setopt_array($curl, array(     curlopt_url => "{$baseurl}{$userid}",      curlopt_customrequest => 'put',  // -x     curlopt_postfields => 'user[avatar][url]=http://domain/canvas/avatar.jpg', // -f     curlopt_httpheader => $header // -h )); $result = curl_exec($curl); curl_close($curl);
