Php From File To Javascript Cant get javascript to display information from PHP file

chireficken · December 3, 2009

Hey All,

I'm stuck! I am trying to use PHP variables accessed from an external file in javascript code.
I can set the array from the external file.
I can get PHP variables to javascript. I can get PHP array variables to javascript.
Something goes wrong when I try to move the array variables into javascript. I even tried setting a single variable for just one element of the array and then accessing that single variable in javascript, still no dice.

Anyway, here is my code. Any help would be VERY appreciated:

<body><?php$cal=(file("test.txt")); // test.txt is just a file with lines 1=day1 info, 2=day2 info etc on separate lines$day5=$cal[4];echo $day5; //successfully echoes '5=day5 info'?><script language="JavaScript" type="text/javascript">document.write("<?php echo $day5 ?>"); //no dice!!  Nothing comes out.  If I put in a line in the php redefining $day5='this sucks' it works fine</script><?php echo $day5; ?>  // just to check that the variable is still accessible during the javascript, and it is</body>

I'm no PHP or java expert...but I've tried few ways and I think the reason it's not working is because it recalls only the last array value when calling within java script.

Everything else keeps the array intact but when this array is called within your java script, it only calls the last value.

Is there a particular reason why you want to call PHP value using java script? Why not just use PHP as a whole page? For example (and I know this defeats the purpose of writhing as PHP and then call it from java),

<?phpfunction foo($num){$cal=file("test.txt");echo $lines[$num];}echo "<script language=\"JavaScript\" type=\"text/javascript\">document.write(\"" . foo(3) . "\"); </script>";?>

I guess the better question is, are you trying to pass PHP variable to JAVA environment?
