有人知道这段代码出了什么问题吗?它并没有给我一个实际的图片,而是给了我一个图片错误。我认为我已经正确设置了所有的函数和其他内容。有任何建议都将不胜感激。
<?php
function resizeImage($filename, $max_width, $max_height) {
list($orig_width, $orig_height) = getimagesize($filename);
$width = $orig_width;
$height = $orig_height;
# taller
if ($height > $max_height) {
$width = ($max_height / $height) * $width;
$height = $max_height;
}
# wider
if ($width > $max_width) {
$height = ($max_width / $width) * $height;
$width = $max_width;
}
$image_p = imagecreatetruecolor($width, $height);
$image = imagecreatefromjpeg($filename);
imagecopyresampled($image_p, $image, 0, 0, 0, 0,
$width, $height, $orig_width, $orig_height);
return $image_p;
}
$directory = "uploads/";
$images = glob($directory."*");
foreach($images as $image) {
// Set a maximum height and width
$width = 200;
$height = 200;
$newImage = resizeImage($image, $width, $height);
echo '<img src="'.$newImage.'" /><br />';
}
?>
