davefootball123 Posted August 25, 2012 Share Posted August 25, 2012 I have my warning map fairly well done. It is a background image and if there is warning for a specific location then that overlay shows. However I would like to make the overlays showing into 1.PNG image if possible. Here's my code <?php ob_start(); $url = 'http://www.weatheroffice.gc.ca/rss/warning/on-94_e.xml'; $search_torwatch = 'TORNADO WATCH IN EFFECT'; $search_svrwatch = 'SEVERE THUNDERSTORM WATCH IN EFFECT'; $search_torwarn = 'TORNADO WARNING IN EFFECT'; $search_svrwarn = 'SEVERE THUNDERSTORM WARNING IN EFFECT'; $file_contents = file_get_contents($url); if(strpos($file_contents, $search_torwarn) !== FALSE){ // There's a watch. echo '<center><img style="position:absolute;left:50%;margin-left:-397px; margin-top:30px" src="/Warningoverlays/TOR Warn/windsor.png" border="0">'; } else if(strpos($file_contents, $search_svrwarn) !== FALSE){ // There's a watch. echo '<center><img style="position:absolute;left:50%;margin-left:-397px;

Jessica Posted August 25, 2012 Share Posted August 25, 2012 First of all, you have the same code over and over again - you need to either make it a function, or start using some arrays and loops. Secondly, I don't see any code in there that is attempting to create an image using PHP. What have you tried so far?

darkfreaks Posted August 25, 2012 Share Posted August 25, 2012 i agree with the above your code looks messy and cluttered with all the if statements. it would look much neater if you put some of that into a function like this... function getLineWithString($fileName, $str) { $lines = file($fileName); foreach ($lines as $lineNumber => $line) { if (strpos($line, $str) !== false) { return $line; } } return -1; } this should search for the line in the file and return it if it does not equal FALSE. then output the function and echo the correct picture.
