php – mobile operator consultation

Question:

I started a query to find out which cell phone operator is pulling from a website. However, I can only do one at a time. I would like help so that I could paste a list and it would send requests and print the result separately.

<?php
$fone = $_POST['tel_fone']; 
$fone = preg_replace("/[^0-9]/", "", $fone); function get_operadora($fone){ $url = "http://consultanumero.info/consulta";
$ch = curl_init(); 
curl_setopt ($ch, CURLOPT_USERAGENT, "Mozilla/5.0 (Windows NT 6.1; rv:32.0) Gecko/20100101 Firefox/32.0"); 
curl_setopt ($ch, CURLOPT_REFERER, 'http://google.com.br/'); 
curl_setopt ($ch, CURLOPT_CONNECTTIMEOUT, 5); 
curl_setopt ($ch, CURLOPT_SSL_VERIFYPEER, 0); 
curl_setopt ($ch, CURLOPT_SSL_VERIFYHOST, 0); 
curl_setopt ($ch, CURLOPT_URL, $url); 
curl_setopt ($ch, CURLOPT_POST, 1); 
curl_setopt ($ch, CURLOPT_POSTFIELDS, "tel=$fone"); 
curl_setopt ($ch, CURLOPT_RETURNTRANSFER, true); 
$data = curl_exec ($ch); if(preg_match("/(oi)/",$data )){ $resultado = "OI"; } if(preg_match("/(vivo)/",$data )){ $resultado = "VIVO"; } if(preg_match("/(tim)/",$data )){ $resultado = "TIM"; } if(preg_match("/(claro)/",$data )){ $resultado = "CLARO"; } if(preg_match("/(nextel)/",$data )){ $resultado = "NEXTEL"; } return trim($resultado); curl_close ($ch); } 
$operadora = get_operadora($fone);
?>

Answer:

The site in question ( consultanumero.info/consulta ) has implemented a ReCaptcha, which makes the code below not work currently.

You can just do a foreach of type`

$numeros = [
 '11999999999',
 '22988888888',
 '21912345678'
];

Then do:

foreach($numeros as $numero){

    get_operadora($numero);

}

But there are several that can worsen performance, see this:

 if (preg_match("/(oi)/", $data)) {
     $resultado = "OI";
 }
 if (preg_match("/(vivo)/", $data)) {
     $resultado = "VIVO";
 }
 if (preg_match("/(tim)/", $data)) {
     $resultado = "TIM";
 }
 if (preg_match("/(claro)/", $data)) {
     $resultado = "CLARO";
 }
 if (preg_match("/(nextel)/", $data)) {
     $resultado = "NEXTEL";
 }
 return trim($resultado);
 curl_close($ch);

"Errors":

  1. No phone has two operators, so it's either OI or VIVO , your code doesn't care about that. If it finds OI it will still search for VIVO , for TIM , for CLARO … Using elseif would reduce this.

  2. curl_close() will never be used, return is before it.

A better option would be to use multi_curl and use preg_match , so removing the if and curl will run faster:

function get_operadora(array $telefones){

    $curlIndividual = [];
    $operadora = [];

    $curlTodos = curl_multi_init();

    foreach($telefones as $telefone){

        $curlIndividual[$telefone] = curl_init('https://consultanumero.info/consulta');

        curl_setopt_array($curlIndividual[$telefone], [
            CURLOPT_USERAGENT => 'Mozilla/5.0 (Windows NT 6.1; rv:32.0) Gecko/20100101 Firefox/32.0',
            CURLOPT_SSL_VERIFYPEER => 1,
            CURLOPT_SSL_VERIFYHOST => 2,
            CURLOPT_CONNECTTIMEOUT => 5,
            CURLOPT_PROTOCOLS => CURLPROTO_HTTPS | CURLPROTO_HTTP,
            CURLOPT_POST => 1,
            CURLOPT_POSTFIELDS => 'tel='.$telefone,
            CURLOPT_RETURNTRANSFER => 1
        ]);


        curl_multi_add_handle($curlTodos, $curlIndividual[$telefone]);

    }


    $Executando = 1;

    while($Executando> 0){
        curl_multi_exec($curlTodos, $Executando);
        curl_multi_select($curlTodos);
    }


    foreach($curlIndividual as $telefone => $curl){

        $resultado = curl_multi_getcontent($curl);

        if(preg_match('/<img src="(.*?)" alt="(.*?)" title="(.*?)" \/>/', $resultado, $matches)) {

            $operadora[$telefone] = $matches[2];

        }

    }

    return $operadora;

}

Changes:

  • Only accepts array .

  • Verifies SSL with certificates you trust, due to CURLOPT_SSL_VERIFYPEER , which is recommended and defaults to PHP 7.1 .

  • It only uses HTTP/HTTPS, defined in CURLOPT_PROTOCOLS .

  • Uses multi_curl , defined in curl_multi_exec .

  • Gets the operator based on the <img src="(.*?)" alt="(.*?)" title="(.*?)" \/> , without any if .

Use:

$numeros = [
    '11999999999',
    '22988888888',
    '21999991234'
];


get_operadora($numeros);

Return:

array(3) {
  ["11999999999"]=>
  string(4) "Vivo"
  ["22988888888"]=>
  string(2) "Oi"
  ["21999991234"]=>
  string(4) "Vivo"
}

Tested on PHP 7.1, old versions may have incompatibility.

Heads up:

Consider this as an example, the ideal would be to break this into several functions and check that all the variables are being defined correctly.
