如何从PHP数组中检索值？

Question

I have a array stored in a PHP file in which I am storing all the values.

I am trying to loop through the entire array in JavaScript. How should I do that?

The following does not work:

var index = 0;
var info = 1;

while(index<4) {
    info = <?php echo $a[?>index<?php];?>
    index++;
}

I don't know what version of php you're using, but try something like this:

var info = null;
var a = <?php echo json_encode($a); ?>;

for(var index=0;index<a.length;index++) {
    info = a[index];
}
