Is there a maximum number of lines in a php string/JS alert box?

Question

I want to output some array data (>30.000 indexes) in php using a JavaScript alert box. So I create the string in a for loop containing all of my data with

$content .= '\\n' . data[$i];

Then I want to output the data using

echo "<script type='text/javascript'>
alert('$content');
</script>";

I'm just wondering what the maximum number of lines is that you can input in a php string or a javascript alert box. I know it won't display 30.000 lines but what is the maximum number?

You could use the JS join() method for concatenating arrays: `data.join("\\n")` — Daniel, Aug 06 '15 at 12:52
Not at all an answer, but an alert box is imo totally the wrong tool for the job — PeeHaa, Aug 06 '15 at 12:56
I'm trying to limit the maximum from my for loop. I just want to check how many lines I can display to test the output ;-) — Dennis Konoppa, Aug 06 '15 at 12:57

A string can be as large as 2GB.

And yes, this question looks like a duplicate. – Miguel Xoel Garcia Aug 06 '15 at 12:56
I closed it as a dupe which mostly contains info about the JS side, so you remark about php is still useful. Although if you put a 2GB string in a alert big you probably have bigger problems :P – PeeHaa Aug 06 '15 at 12:58
