imagecreatefrompng error

问题:

<?php function LoadPNG($imgname) {     /* Attempt to open */     $im = @imagecreatefrompng($imgname);      /* See if it failed */     if(!$im)     {         /* Create a blank image */         $im  = imagecreatetruecolor(150, 30);         $bgc = imagecolorallocate($im, 255, 255, 255);         $tc  = imagecolorallocate($im, 0, 0, 0);          imagefilledrectangle($im, 0, 0, 150, 30, $bgc);          /* Output an error message */         imagestring($im, 1, 5, 5, 'Error loading ' . $imgname, $tc);     }      return $im; }  header('Content-Type: image/png');  $img = LoadPNG('http://www.prideofhome.com/wp-content/uploads/328145505image_11.png');  imagepng($img); imagedestroy($img); ?> 

i am getting error..how to solve.is imagecreatefrompng doesnt support the file from remote server.

回答1:

To use a file from a remote server, use imagecreatefromstring in conjunction with file_get_contents:

$im = imagecreatefromstring(file_get_contents($imgname)); 

Note that a URL can be used as a filename with file_get_contents only if fopen wrappers have been enabled.

If this doesn't solve your problem, clarify your question. Give at least the error you're receiving. :)

回答2:

Removing the @ will let you see what's wrong. Either the apppropriate option isn't set, or the gd extension was built without PNG support, or the remote file doesn't exist/can't be downloaded.
