PHP-Programs - Javascript document.write inside php

Can anyone please help me get this code to work?
It works fine if I use only PHP coding in code#3.
How can I use the "document.write" method in code#3 ?

1) The following code was saved as TESTcall.htm. Program was called by this.

<script type="text/javascript" src=xxxxxxxxxxxxx></script>

............................

2) This test text was saved as TEST.txt in the same folder as TEST.php

aaaa
bbbb
cccc
dddd
eeee
ffff
gggg
hhhh
.............................

3) This code was saved as TEST.php

<?php
$quotes = file(xxxxxxxxxxxxxxx);
srand((double)microtime() * 1000000);
$ranNum = rand(0, count($quotes)-1);
echo 'document.write(\"start<BR>". $quotes[$ranNum]; ."<BR>end\");';
?>

.............................

All 3 files are in the same folder on my php-available website server.
I have tried all variations of single quotes and double quotes with and without the backslash inside the "document.write" but cannot get any output!
What am I doing wrong here??

Welcome to the forum, there's a new user guide in my signature you may find useful.

Using [ PHP ] and [/ PHP ] tags (without spaces) around your code will automatically color it. Look at your code:

PHP Code:


		
			
echo 'document.write(\"start<BR>". $quotes[$ranNum]; ."<BR>end\");';

And now look at the corrected code:

PHP Code:


		
			
echo 'document.write("start<BR>' . $quotes[$ranNum] . '<BR>end");';

See the coloring difference?

You may want to use json_encode as well, otherwise any newlines or quotation marks in the value will break your JavaScript.

PHP Code:


		
			
echo 'document.write("start<br />" + ' . json_encode(trim((string)$quotes[$ranNum])) . ' + "<br />end");';
