Question

I have an generated output.js file from a specific device which contains Array in it:

var OUT=new Array (0x80,0x00,0x40,0x0026,0x0011,0x0014,0x0013,0x0018,0x0017,0x03FD,0x0116)

How can i get access to this array with PHP, so i can easily print specified Array[x] in any location:

print $OUT[4];

With simple JS i was able to do it like:

document.write(OUT[4]);

In case i can also handle that output.js with PHP like a txt file and then splitting and “doing like array thing” but i think there is away to use it right.. ^_^

Any tips or suggestions on that ? 🙂

Thnx!

If you want to fetch the file directly with PHP then you can either write a custom parser (using regular expressions if you can trust the file format to be consistant) or by interfacing with a JavaScript engine.

Otherwise, assuming the JavaScript is running in a web browser…

The simplest way to do this would be to make use of createElement and appendChild while looping over an array to create a form element containing a hidden input for each element of the array (with a name such as foo[] to satisfy the algorithm PHP uses to populate $_POST and friends) and then submit() the form.

Alternatively, you could serialise the array to a string (e.g. a comma separated one if you know that there are no commas in the data) and create a query string with it (var qs = "?foo=" + encodeURIComponent(serialised_array);) and then pass it using XMLHttpRequest.
