I'm looking for a way at the beginning of the function to check if the file exists, and if it does not, then stop, but allow the file to continue. I don't want the entire script to cease if certain files are missing. For example (see bottom of script), if 'thr.png' does not exist, stop function, and start the next function ('bv1.png').
Code: Select all
<?php
function radar_status($radar)
{
$now = time();
$now -= 720; // 12 minutes
$filetime = filemtime("/".$radar);
if ($now = $filetime)
$active = '';
else
$active = 'This image is not current';
header("Content-Type: image/png");
$im = imagecreatefrompng($radar);
$red = ImageColorAllocate($im, 255, 0, 0);
$start_x = 250;
$start_y = 375;
imagettftext($im, 24, 0, $start_x, $start_y, $red, 'ArialBold.ttf', $active);
imagepng($im,$radar);
imagedestroy($im);
}
radar_status('br1.png');
radar_status('br2.png');
radar_status('br3.png');
radar_status('br4.png');
radar_status('br248.png');
radar_status('srv1.png');
radar_status('srv2.png');
radar_status('thr.png');
radar_status('bv1.png');
radar_status('bv2.png');
?>Thank you!
