下载之前，请检查远程服务器上是否存在映像
|
我试图从远程服务器下载图像，调整大小，然后将其保存在本地计算机上。
为此，我使用WideImage。
<?php
include_once($_SERVER[\'DOCUMENT_ROOT\'].\'libraries/wideimage/index.php\');
include_once($_SERVER[\'DOCUMENT_ROOT\'].\'query.php\');
do {
wideImage::load($row_getImages[\'remote\'])->resize(360, 206, \'outside\')->saveToFile($_SERVER[\'DOCUMENT_ROOT\'].$row_getImages[\'local\']);}
while ($row_getImages = mysql_fetch_assoc($getImages));
?>
do {
if(file_exists($row_getImages[\'remote\'])){
wideImage::load($row_getImages[\'remote\'])->resize(360, 206, \'outside\')->saveToFile($_SERVER[\'DOCUMENT_ROOT\'].$row_getImages[\'local\']);}
}
while ($row_getImages = mysql_fetch_assoc($getImages));
没有找到相关结果
