</span><span> 2</span> <span>$data_string</span> = json_encode(<span>$data</span><span>); 
</span><span> 3</span> <span>$ch</span> = curl_init('http://api.local/rest/users'<span>); 
</span><span> 4</span> curl_setopt(<span>$ch</span>, CURLOPT_CUSTOMREQUEST, "POST"<span>); 
</span><span> 5</span> curl_setopt(<span>$ch</span>, CURLOPT_POSTFIELDS, <span>$data_string</span><span>);
</span><span> 6</span> curl_setopt(<span>$ch</span>, CURLOPT_RETURNTRANSFER, <span>true</span><span>);
