create javascript file with php

I have a php script on my server that connects to the database and pulls out banners based on location. We have a third party company that handles these banners but they only accept javascript code and not php so I need to make all the php execute on my server and then write the results to a js file that they can retrieve and take it from there. I am not sure on how to do this so any help will be appreciated.

Right now the code displays the javascript on the page but it should write it to a javascript file that the third party can access and use accordingly.
$db_server = "db_server";
$db_user = "db_user";
$db_pass = "db_pass";
$db_name = "db_name"; 
 
mysql_connect($db_server,$db_user,$db_pass) or die(mysql_error());
mysql_select_db($db_name) or die(mysql_error());
 
if(isset($_POST['change_region'])) {
	$change_region = $_POST['change_region'];
	$change_county =$_POST['change_county'];
	$change_city = $_POST['change_city'];
	setcookie('change_region',$change_region,time()+60*60*24*30);
	setcookie('change_county',$change_county,time()+60*60*24*30);
	setcookie('change_city',$change_city,time()+60*60*24*30);
} else {
$change_region = $_COOKIE['change_region'];
$change_county =$_COOKIE['change_county'];
$change_city = $_COOKIE['change_city'];
}

if you replace your php-built script with code below you will find a bannerscript.js in the same folder as script above is located after running.
Change $filename to change the name and/or location of the generated script.
fopen command generates a file (parameter 'w' gives write priviliges)
fwrite command writes a line in the generated file
fclose command closes the file after finishing.

Good luck!
<?php
 
$filename = "bannerscript.js";
 
$bf = fopen($filename, 'w');
 
fwrite($bf, 'document.write(\'<a href="http://www.insidetoday.com/ban_click.php?id=');
 
fwrite($bf, urlencode($hed_ban['banner_id'])); 
 
fwrite($bf, '&url='.urlencode($hed_ban['link_url']));
 
fwrite($bf, ' target="_blank">');
 
if($hed_ban['banner_image']) { 
 
	fwrite($bf, '<img src="http://www.insidetoday.com/bannerimages/'.$hed_ban['banner_image'].' alt="ad" width="468" height="60" border="0" />');
 
}
 
fwrite($bf, '</a>\');');
 
fclose($bf);

Do you have write permissions on the directory where the script runs?
As long as the fopen command is not permitted, the fwrite and fclose will fail also

Yes I do have permissions to create new files, write to them and change the permissions on subfolders and stuff. Do I need to make the file trulia_header.php a 777 or something. Let me know

You could first try and change the line
$bf = fopen($filename, 'w');

into:
$bf = fopen($filename, 'w+');

or:
$bf = fopen($filename, 'wr');

Hi JurgenvH,
I tried both of the lines of code you gave me but I am getting the same error. Let me know if I need to contact my host to figure out the permissions scenario. Thanks for all the help.

The script is working but the only addition I need to make is right now the output on bannerscript,js needs to be enclosed in a javascript function called bannerscript() like this

function bannerscript()
{
document.write('<a href="http://www.insidetoday.com/ban_click.php?id=89&url=www.insidetoday.com target="_blank"><img src="http://www.insidetoday.com/bannerimages/89_trulia_banner.gif alt="ad" width="468" height="60" border="0" /></a>');
}
