Why does this code doesn't work on Xampp? It works fine in an online 'real' server but not on my local xampp.
Any ideas?
Any code that i've tested to generate graphics wont work locally.
Example:
- Code: Select all
<?
// Add values to the graph
$graphValues=array(0,80,23,11,190,245,50,80,111,240,55);
// Define .PNG image
header("Content-type: image/png");
$imgWidth=250;
$imgHeight=250;
// Create image and define colors
$image=imagecreate($imgWidth, $imgHeight);
$colorWhite=imagecolorallocate($image, 255, 255, 255);
$colorGrey=imagecolorallocate($image, 192, 192, 192);
$colorBlue=imagecolorallocate($image, 0, 0, 255);
// Create border around image
imageline($image, 0, 0, 0, 250, $colorGrey);
imageline($image, 0, 0, 250, 0, $colorGrey);
imageline($image, 249, 0, 249, 249, $colorGrey);
imageline($image, 0, 249, 249, 249, $colorGrey);
// Create grid
for ($i=1; $i<11; $i++){
imageline($image, $i*25, 0, $i*25, 250, $colorGrey);
imageline($image, 0, $i*25, 250, $i*25, $colorGrey);
}
// Create line graph
for ($i=0; $i<10; $i++){
imageline($image, $i*25, (250-$graphValues[$i]), ($i+1)*25, (250-$graphValues[$i+1]), $colorBlue);
}
// Output graph and clear image from memory
imagepng($image);
imagedestroy($image);
?>
Thanks.
