How to receive data from a WEBHOOK in php (Data sent in $_POST by webhook)

Question

Beginner in programming if anyone can help me.

<?php
    
    ini_set('display_errors',1);
    ini_set('display_startup_erros',1);
    error_reporting(E_ALL);
    
    header('Access-Control-Allow-Origin: *');
    header("Access-Control-Allow-Methods: GET, POST, OPTIONS, PUT, DELETE");
    header("Access-Control-Allow-Headers: Content-Type, Access-Control-Allow-Headers, X-Requested-With");
    
    
    if(!empty($_POST['nome']) && !empty($_POST['email']) && !empty($_POST['telefone']  && !empty($_POST['formId'])){
    
    //  echo "Variaveis  enviadas";
        
        $data = $_POST['nome'];
        $data = $_POST['email'];
        $data = $_POST['telefone'];
        
        $data['telefone_key'] = substr($data['telefone'], 3);
    
        if(strlen($data['telefone_key']) == 10){
            $newTel = substr($data['telefone_key'], 0, 2) . "9" . substr($data['telefone_key'], 2);
            $data['telefone_key'] = $new;
        }
    
        $data['telefone_criptografado'] = criptografar($data['telefone']);
    
    
        $formId = $_POST['formId']; 
        pushMauticForm($data,$formId);
    
    } else {    
        echo "Variaveis não enviadas";
    }
    
    function criptografar(telefone){
        
         $tel = telefone.toString();
    
        $remover = array("(", ")", "+", " ", "-");
        str_replace($remover, "", $tel);
    
        
    
        $cifra = [ "0", "1", "1", "2", "2", "2", "3", "3", "3", "3"];
        $telCripto = "";
        for ($i = 0; $i < $tel.length; $i++) {
            $telCripto += $cifra[parseInt($tel[i])];
        }
        return $telCripto;
    }
    
    
    function pushMauticForm($data, $formId, $ip = null){
    
        $ip = "191.252.129.245";
        
    
        $dados = array("dados" => $data, "formId" => $formId);
        //print_r($dados);
    
        $content = http_build_query($dados);
    
        //print_r($content);
    
        $context = stream_context_create(array(
            'http' => array(
                'header' => "Content-Type: application/x-www-form-urlencoded\r\n",
                "Content-Length:" .strlen ($content),
            'method' => 'POST',
            'content' => $content,
            )
            ));
            //echo "<br>";
            //print_r($context);
    
        $result = file_get_contents('https://teste.com.br/', null, $context);
    
    }
    
    ?>

This is the code I have to receive the information that my webhook sends, I tested it is normally sending the information, but the url that contains this my code is appearing error 500 and I can’t identify which error I’ve searched and can’t find, I put the code to php to show me the errors, but it is not showing. I’ll put up the prints. You are returning error 500 Print test Webhook: https://prnt.sc/17o7kzh Print reply screen URL: https://prnt.sc/17o7ua7

I managed to find the error, is in the encryption function had forgotten to put the $ to declare the variable, before phone. Tiredness is fucking kkkkk, sometimes just stop a little stretch the body and come back. Corrected function.

function criptografar($telefone){
    
     $tel = $telefone.toString();

    $remover = array("(", ")", "+", " ", "-");
    str_replace($remover, "", $tel);

    

    $cifra = [ "0", "1", "1", "2", "2", "2", "3", "3", "3", "3"];
    $telCripto = "";
    for ($i = 0; $i < $tel.length; $i++) {
        $telCripto += $cifra[parseInt($tel[i])];
    }
    return $telCripto;
}
