Posting JSON to URL using PHP curl - php

Question

I have the following JSON code:
{"username":"user1","password":"123456"}
That I need to pass to a url, lets say: http://api.mywebsite.com
I'm an extreme php newb, so I've been following a curl tutorial, but here is my current PHP code:
<?php
function get_web_page( $url )
{
$options = array(
CURLOPT_RETURNTRANSFER => true, // return web page
CURLOPT_HEADER => true, // don't return headers
CURLOPT_FOLLOWLOCATION => true, // follow redirects
CURLOPT_ENCODING => "", // handle compressed
CURLOPT_USERAGENT => "spider", // who am i
CURLOPT_AUTOREFERER => true, // set referer on redirect
CURLOPT_CONNECTTIMEOUT => 120, // timeout on connect
CURLOPT_TIMEOUT => 120, // timeout on response
CURLOPT_MAXREDIRS => 10, // stop after 10 redirects
);
$ch = curl_init( $url );
curl_setopt_array( $ch, $options );
$content = curl_exec( $ch );
$err = curl_errno( $ch );
$errmsg = curl_error( $ch );
$header = curl_getinfo( $ch );
curl_close( $ch );
$header['errno'] = $err;
$header['errmsg'] = $errmsg;
$header['content'] = $content;
return $header;
}
?>

Answer 1

You might want to look into the CURLOPT_POSTFIELDS AND CURLOPT_POST options. These allow you to do a POST request and pass the data set into the CURLOPT_POSTFIELDS in the request.
Something in the lines of this:
$body = 'bar=1&foo=2&baz=3';
$c = curl_init ($url);
curl_setopt ($c, CURLOPT_POST, true);
curl_setopt ($c, CURLOPT_POSTFIELDS, $body);
curl_setopt ($c, CURLOPT_RETURNTRANSFER, true);

When you want to use normal GET Params:
$jsonString ='{"username":"user1","password":"123456"}';
$params = json_decode($jsonString);
$getParams = '';
$first = true;
foreach ($params as $key => $param){
if ($first){
$getParams .= '?';
$first = false;
} else{
$getParams .= '&';
}
$getParams .= $key .'=' .$param;
}
echo $getParams;
get_web_page($url . $getParams);
