Question

I have a method to save an image, which is meant to deal gracefully with an error, setting $imageSrc to a particular image in the event of failure. My method works fine if the image is present, but no error conditions seems to be handled correctly.

$imageSrc = save_pic($PIC_URL, $pk);  function save_pic($pic_url, $pk) {     $imageDir = './';     if (!strlen($pic_url))             return 'removed.jpg';     if (!is_dir($imageDir) || !is_writable($imageDir)) {         return 'removed.jpg';     }     $image = file_get_contents($pic_url);     if (empty($image)) {         return 'removed.jpg';     }     $r = file_put_contents($imageDir.$pk.'.jpg', $image);     if ($r) {             return './$pk.jpg';      } else {             return 'removed.jpg';     } } 

If the image does not exist, I get :

Warning: getimagesize(http://127.0.0.1/555.jpg) [function.getimagesize]: failed to open stream: HTTP request failed! HTTP/1.1 404 Not Found in C:\Program Files\EasyPHP 2.0b1\www\get_auction.php on line 144  Array (  [type] => 2 [message] => getimagesize(http://127.0.0.1/555.jpg)  function.getimagesize]: failed to open stream: HTTP request failed! HTTP/1.1 404 Not Found  [file] => C:\Program Files\EasyPHP 2.0b1\www\get_auction.php  [line] => 144 ) 1 

returned.jpg is never returned in any event.

edit: added imageResize code:

function imageResize($imageURL, $maxWidth, $maxHeight)  {  global $outputWidth, $outputHeight, $maxWidth, $maxHeight;  $size = getimagesize($imageURL);  if ($size) {      $imageWidth  = $size[0];      $imageHeight = $size[1];      $wRatio = $imageWidth / $maxWidth;      $hRatio = $imageHeight / $maxHeight;      $maxRatio = max($wRatio, $hRatio);        if ($maxRatio > 1) {          $outputWidth = $imageWidth / $maxRatio;          $outputHeight = $imageHeight / $maxRatio;      } else {          $outputWidth = $imageWidth;          $outputHeight = $imageHeight;      }  } else {      die(print_r(error_get_last()));  }  }

The problem was not a code issue, but was caused by file corruption. This was determined while testing on other machines.
