I need to create a array in javascript tag that is submitted your information to a page php .

How can I do this?

Next, I had a php that I uploaded, repeated data from the bank. So to improve her performance, I've created a script in javascript I copied the contents of the tables. But each table has a option and every option has a selected , so I need every option to start as its specific phrase, just like the whole pg in php . For this I did the script below:

<script src="http://ajax.googleapis.com/ajax/libs/jquery/1.10.2/jquery.min.js"></script><script>$(document).ready(function(){//frasequedesejolocalizarvarfrase="minAlarme4_analogico00",
        localizado = null;

    // loop que percorre cada uma das opções
    // e verifica se a frase da opção confere com o
    // valor de fase que está sendo procurado
    // valor de fase que está sendo procurado
    $('#Linha5 option').each(function() {
      // se localizar a frase, define o atributo selected
      if($(this).attr('value') == frase) {
        $(this).prop('selected', true);
      }
    });
});
</script>

However (minAlarme4_analogico00 ") is the name of a sensor and I have type 1500. So I need an array to communicate with the php tag so that the same get the names of the sensors.

You can use JSON.stringify(array) in JavaScript to encode the array and send it to PHP, where you use $array = json_decode($_POST['dados']); to read the passed variable.

If you want to do something dynamically, you should use AJAX , which would look something like this: / p>

No JS

meuArray = ??? ;
var arrayCodificado = JSON.stringify(meuArray);
$.ajax({
    type: "POST",
    url: "script.php",
    data: { dados: arrayCodificado }, 
    cache: false,
    success: function(){
        alert("Feito!");
    }
});

In PHP

$meuArray = json_decode(stripslashes($_POST['dados']));
foreach($meuArray as $d){
    echo $d;
}
