PHP - Insert a variable into an array - php

Question

Say we have this array
$args = array('responseType' => 'Xml',
'serverName' => 'vl18278.dinaserver.com',
'command' => 'Vps_GetUsedSpace',
) ;
This array composes an URL to send through cURL. I need to replace vl18278.dinaserver.com with a variable $vps, but when I replace it, the URL show a %5B0%5D just before the = sign of the attribute serverName:
responseType=Xml&serverName%5B0%5D=vl18278.dinaserver.com&command=Vps_GetUsedSpace
If I dont replace the vl18278.dinaserver.com, the URL is correct.
What is wrong with my code? Why are those %5B0%5D getting into my URL? :(
Thanks in advance.
Complete code:
<?php
$listavps = simplexml_load_file('servers.xml');
foreach ($listavps->servers->server as $vps) {
$urlApi = 'url.php';
$username = 'user';
$password = 'pass';
$args = array('responseType' => 'Xml',
'serverName' => 'vl18278.dinaserver.com',
'command' => 'Vps_GetUsedSpace',
) ;
$args = ( is_array ( $args ) ? http_build_query ( $args, '', '&' ) : $args );
$headers = array();
$handle = curl_init($urlApi);
if( $handle === false ) // error starting curl
{
$error = '0 - Couldn\'t start curl';
}
else
{
curl_setopt ( $handle, CURLOPT_FOLLOWLOCATION, true );
curl_setopt ( $handle, CURLOPT_RETURNTRANSFER, true );
curl_setopt ( $handle, CURLOPT_URL, $urlApi );
curl_setopt( $handle, CURLOPT_USERPWD, $username.':'.$password );
curl_setopt( $handle, CURLOPT_HTTPAUTH, CURLAUTH_BASIC );
curl_setopt( $handle, CURLOPT_TIMEOUT, 60 );
curl_setopt( $handle, CURLOPT_CONNECTTIMEOUT, 4); // set higher if you get a "28 - SSL connection timeout" error
curl_setopt ( $handle, CURLOPT_HEADER, true );
curl_setopt ( $handle, CURLOPT_HTTPHEADER, $headers );
$curlversion = curl_version();
curl_setopt ( $handle, CURLOPT_USERAGENT, 'PHP '.phpversion().' + Curl '.$curlversion['version'] );
curl_setopt ( $handle, CURLOPT_REFERER, null );
curl_setopt ( $handle, CURLOPT_SSL_VERIFYPEER, false ); // set false if you get a "60 - SSL certificate problem" error
curl_setopt ( $handle, CURLOPT_POSTFIELDS, $args );
curl_setopt ( $handle, CURLOPT_POST, true );
$response = curl_exec ( $handle );
echo $args;
if ($response)
{
$response = substr( $response, strpos( $response, "\r\n\r\n" ) + 4 ); // remove http headers
// parse response
$responseSimpleXml = simplexml_load_string($response);
if( $responseSimpleXml === false )
{
// invalid xml response
}
else
{
// parse response
$errorCode = $responseSimpleXml->response->responseCode ;
echo $errorCode;
if( $errorCode == 1000 ) // success
{
$usado = $responseSimpleXml->response->data->total_space;
$capacidad = $responseSimpleXml->response->data->space_limit;
echo 'Usado: '.$usado.'</br>Total: '.$capacidad.'.';
}
else // normal errors
{
$errors = $responseSimpleXml->response->errors;
foreach( $errors->error as $error )
{
// process error
}
}
}
}
else // http response code != 200
{
$error = curl_errno ( $handle ) . ' - ' . curl_error ( $handle );
}
curl_close($handle);
}
}
?>

Answer 1

Your variable $server must be an array, because, once decoded, %5B0%5D is [0].
My guess is to use $server[0] instead of $server wherever you replace the value. Without the replacement code, it is hard to determine.

I solved this using rawurlencode in the $listavps variable before using it.
<?php
$listavps = simplexml_load_file('servers.xml');
foreach ($listavps->servers->server as $key => $tag) {
$vps = rawurlencode ($tag);
$urlApi = 'url.php';
$username = 'user';
$password = 'pass';
$args = array('responseType' => 'Xml',
'serverName' => $vps,
'command' => 'Vps_GetUsedSpace',
) ;
