这是以下示例中提供的代码:http://www.php.net/manual/en/function.imagecopyresampled.php
test.jpg尺寸:500x357
phpdotnet_resize.php
这显示test.jpg调整为200x142
<?php
// The file
$filename = 'test.jpg';
// Set a maximum height and width
$width = 200;
$height = 200;
// Content type
header('Content-Type: image/jpeg');
// Get new dimensions
list($width_orig, $height_orig) = getimagesize($filename);
$ratio_orig = $width_orig/$height_orig;
if ($width/$height > $ratio_orig) {
$width = $height*$ratio_orig;
} else {
$height = $width/$ratio_orig;
}
// Resample
$image_p = imagecreatetruecolor($width, $height);
$image = imagecreatefromjpeg($filename);
imagecopyresampled($image_p, $image, 0, 0, 0, 0, $width, $height, $width_orig, $height_orig);
// Output
imagejpeg($image_p, null, 100);
echo "<img src='$filename'>";
?>
但是,这会将test.jpg显示为原始大小500x357
<?php
include "phpdotnet_resize.php";
echo "<img src='$filename'>";
?>
我正在尝试将已调整大小的test.jpg移动到images /但它会继续移动原始大小的图像。

echo "Success";
