Hello,

I have a string that the value is zero ($contador = 0;), other that the value is three ($vezes = 3;) and another that is $numeros = "13|123456789\n14|123456780\n".

I want PHP to do a function (example echo();) up to the string $contador arrive on three, and do this function with the 2 values in the string $numeros, by default:

$ddd = 13; //Pega o valor 13 da string $numeros
$numero = 123456789; //Pega o valor 123456789 da string $numeros
echo "Meu DDD é $ddd e meu celular é $numero!";
//Resposta (vai repetir a função echo acima 3 vezes graças ao valor da string $vezes):
// Meu DDD é 13 e meu celular é 123456789!
// Meu DDD é 13 e meu celular é 123456789!
// Meu DDD é 13 e meu celular é 123456789!

Same thing with the second string value $numeros. And when the string value $contador reach three, the script to.

I couldn’t think of anything that would do that, thank you all at once!

php

  • 13|123456789\n14|123456780\n Is that how you have the data? I don’t understand the part where the loop goes into it. It’s always 2 phone numbers?

  • @Papacharlie The data is sent from a POST form, of this format DD|NUMERO, I want a function that every row that user add (\n) script does the function I quoted.

  • You need to format 13|123456789\n14|123456780\n in 13(*)123456789; 14(*)123456780, that?

  • Exactly, but with so much that the formatting does not affect the result with the function, for example echo "Meu DDD é 13.. e meu celular é 123456789"

  • As if it were an array

  • I just read here in php.net, I don’t understand much, so I thought I’d open a question here at stackoverflow

  • I gave an answer based on what I understood of your question, if it is incorrect I edit. See if you solve.

What you want is to make a loop, there are various and various ways of doing this and various topics about it here.

If the string holds: (DDD)|(NUMERO)\n, each \n you will have a (DDD)|(NUMERO), soon divide the | and will have the (DDD) and the (NUMERO) of each set.

First break the string using explode:

$numeros = "13|123456789\n14|123456780\n";
$numeros = explode("\n", $numeros);

Now you will have an array for each (DDD)|(NUMERO).

Then use can use the for:

for($contador = 0; $contador < 3; $contador++){

    if(isset($numeros[$contador]) && !empty($numeros[$contador])){

     // Use outro explode para dividir entre DDD e NUMERO
     list($ddd, $numero) = explode("|", $numeros[$contador]);
     echo "Meu DDD é $ddd e meu celular é $numero!";
    }

}

You can also use the foreach, to list ALL:

You can also limit using if($index === 3){break;} for example!

foreach($numeros as $index => $numero){

    if(!empty($numero)){
         list($ddd, $numero) = explode("|", $numero);
         echo "Meu DDD é $ddd e meu celular é $numero!";
    }

}

You can test both by clicking here.

  • But I want to receive string values $ddd and $numero string $numeros

  • Like an array, you know?

  • I edited, see if that’s it. : s

  • You’re almost right, you’re thinking that the $contador is setting as much of time as will make the function echo, the $contador is to repeat as much once the function will occur.

Use the explode:

$numeros = "13|123456789\n14|123456780\n";

$contador = 0;
$vezes = 3;

while ($contador < $vezes) {
    $linhas = explode("\n", $numeros);

    foreach($linhas as $linha){
        list($ddd, $numero) = array_pad(explode('|', $linha, 2), 2, null);

        if (isset($ddd, $numero)){
            echo "Meu DDD é $ddd e meu celular é $numero!\n";
        }
        $contador++;
    }

}

// Meu DDD é 13 e meu celular é 123456789!
// Meu DDD é 14 e meu celular é 123456780!

See demonstração

  • There was an error in the demonstration and here. Undefined offset: 1 on line number 11

  • @STRILEXLIVE I already fixed the error, see if this is what you want. I used the variable contador within the foreach not to repeat the same results with each iteration of while, you can put the variable contador outside the foreach if you want.

Using preg_match_all to get the numbers only. You will have an array as below.

Array
(
    [0] => Array
        (
            [0] => 13
            [1] => 123456789
            [2] => 14
            [3] => 123456780
        )

    [1] => Array
        (
            [0] => 13
            [1] => 123456789
            [2] => 14
            [3] => 123456780
        )

)

Using the array contents, you can easily join the DDD and phone number.

preg_match_all( '/(\d+)/' , '13|123456789\n14|123456780\n', $fone );

echo $fone[0][0] . '**' . $fone[0][1]; // 13**123456789
echo $fone[0][2] . '**' . $fone[0][3]; // 14**123456789
