Clone + Rename file with PHP
This should be pretty easy. I wan't to copy & rename images that already exist on the server while still retaining the original image.
Here's the original image location:
images/
folder/
one.jpg
This is what I want:
images/
folder/
one.jpg
one_thumb.jpg
How can I achieve this? You can see I'm not just simply renaming an existing file / image. I want to copy it and rename it to the same directory.
回答1:
Just use the copy method: http://php.net/manual/en/function.copy.php
Ex:
<?php
$file = 'images/folder/one.jpg';
$newfile = 'Images/folder/one_thumb.jpg';
if (!copy($file, $newfile)) {
echo "failed to copy";
}
回答2:
PHP has a function, copy built-in that can do this. Here's an example:
<?php
$file = 'one.jpg';
$newfile = 'one_thumb.jpg';
if (!copy($file, $newfile)) {
echo "failed to copy $file...\n";
}
?>
The function returns a boolean indicating whether the copy was successful. It's as simple as that!
