I'd like to pass arrays through JSON like this:
<?php
for(i=0;i<5;i++) {
$arrayA[i] = "A" . i;
$arrayB[i] = "B" . i;
}
echo json_encode($arrayA,$arrayB);
?>
I know it's not possible, but is there other way to pass dynamicly loaded arrays and read them in javascript after that?
Just put both array in another array.
$returnArr = array($arrayA,$arrayB);
echo json_encode($returnArr);
On JS side just decode with a library of your choice and access the returned array like any normal array.
echo json_encode(array('arrayA' => $arrayA, 'arrayB' => $arrayA));
Just create wrapper for your arrays:
for(i=0;i<5;i++) {
$arrayA[i] = "A" . i;
$arrayB[i] = "B" . i;
}
$arrayC = array($arrayA,$arrayB);
echo json_encode($arrayC);
On jQuery side:
$.getJSON('ajax/yourPhpFile.php', function(data) {
$.each(data, function(key, val) {
// each `val` is one of the arrays you passed from php
});
});
You can use AJAX to load up a script that will return a PHP generated array. If you're using jQuery, you call it using either $.get() or $.getJSON(). You can read up on PHP JSON manual here http://php.net/manual/en/book.json.php and on jQuery .getJson() function here http://api.jquery.com/jQuery.getJSON/
