Question

Reference - What does this error mean in PHP?

I keep on getting a "Parse error: syntax error, unexpected '(', expecting T_VARIABLE or '$' in..."

Here's the line thats causing the problem, not sure whats going on here?

$text = "<script>window.setInterval(function(){$('#liveData').load('liveUpdate.php');}, 1000);</script>";

Thanks in advance

Maybe you should re-read how strings work in PHP... The error is obvious :) http://www.php.net/manual/en/language.types.string.php (hint: you're using a $ inside a string delimited by double quotes) — ItalyPaleAle, Oct 26 '12 at 00:11

You should escape $ in your $text

$text = "<script>window.setInterval(function(){\$('#liveData').load('liveUpdate.php');}, 1000);</script>";

Or you just use single quote.

Because $ in double quote will be followed by a php variable name, $(XXXX is an invalid PHP variable.

So the best way is to separate javascript (jquery) into a .js file.

Second the idea of putting this into a separate file, or at least write it as plain javascript - not sure why the assignment to a PHP variable is needed? – ernie Oct 26 '12 at 00:33

Try this,

$text = '<script>window.setInterval(function(){$("#liveData").load("liveUpdate.php");}, 1000);</script>';
