PHP Implementation for ACINQ/Strike API - php

Question

I need to implement the following curl using PHP.
$ curl https://api.dev.strike.acinq.co/api/v1/charges \
-u sk_pJDwxFxCVw5fQJhRRMpf29jReUjjN: \
-X POST \
-d amount=42000 \
-d currency="btc" \
-d description="1%20Blockaccino"
This is what I have so far.
$post=array();
$post["amount"]=4200;
$post["currency"]="btc";
$post["description"]="1%20Blockaccino";
$ch = curl_init();
curl_setopt($ch, CURLOPT_USERNAME, "sk_pJDwxFxCVw5fQJhRRMpf29jReUjjN:");
curl_setopt($ch, CURLOPT_URL, "https://api.dev.strike.acinq.co/api/v1/charges");
curl_setopt($ch, CURLOPT_POST, TRUE);
curl_setopt($ch, CURLOPT_POSTFIELDS, $post);
$output = curl_exec($ch);
$http = curl_getinfo($ch, CURLINFO_HTTP_CODE);
curl_close($ch);
if ($http==200) {
} else {
}
It returns
{ "code" : 401, "message" : "authentication failed" }
Even though the CURLOPT_USERNAME is accurate. Are there other issues I am not seeing?
Thanks in advance.

Answer 1

CURLOPT_USERNAME was added in PHP 5.5.0.
If you have an older version then you may want to try:
curl_setopt($ch, CURLOPT_USERPWD, "sk_pJDwxFxCVw5fQJhRRMpf29jReUjjN:");

Here is the final WORKING solution...
$post=array();
$post["amount"]=100000;
$post["currency"]="btc";
$post["description"]="test";
$ch = curl_init();
curl_setopt($ch, CURLOPT_USERNAME, "sk_XXXXXXXXXXXXXXXXXXXXXXXXXXXXX");
curl_setopt($ch, CURLOPT_URL, "https://api.strike.acinq.co/api/v1/charges");
curl_setopt($ch, CURLOPT_POST, TRUE);
curl_setopt($ch, CURLOPT_POSTFIELDS, json_encode($post));
curl_setopt($ch, CURLOPT_HTTPHEADER,array("Content-Type: application/json"));
$output = curl_exec($ch);
$http = curl_getinfo($ch, CURLINFO_HTTP_CODE);
curl_close($ch);
if ($http==200) {
} else {
}
