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

Answer 1

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.
