Get information from a JS-generated page with PHP

Question

I have this page that’s on a server where I don’t have access. https://genuncoin.com/crypto/ Open it in the browser and you will see that its jquery generates a number.

I’m trying to get the number it generates but when I use this function:

$page = file_get_contents('http://genuncoin.com/crypto/');

the $page me returns her html without the number only the javas scripts and html of the screen. someone would know how to get the value that is generated by javascript??

Answer 1

the characters being generated are in the variable balancebig and it is displayed on the screen as follows:

$('#bnkPrice').text(balancebig);

As you want to retrieve the information from this variable, I suggest you make an ajax request by sending the contents of this variable to your PHP script. An example of how you could do this is the following:

$.ajax({
    url: 'script.php',
    method: 'post',
    data: {variavel: balancebig},

    success: function(data, textStatus, jqXHR) {
        alert('Caracteres enviados');
    }
});

in your file (which for example I am using script.php you can recover the value using the superglobal post, as you would normally:

$dado = $_POST['variavel'];
