修改php代码上的文件扩展名

Question

抱歉，因为我不知道如何提出问题

我这里有一个PHP代码

$productDetails['country'][0]['image']

输出是：

http://localhost/wine-works.co.uk-tester/wp-content/uploads/2013/09/canada-wine_shop.jpg

如何将文件名更改为：

http://localhost/wine-works.co.uk-tester/wp-content/uploads/2013/09/canada-wine_shop-25x17.jpg

Answer 1

$str= 'http://localhost/wine-works.co.uk-tester/wp-content/uploads/2013/09/canada-wine_shop.jpg';
$suffix = '-25x17';
$name = substr($str,strrpos($str,'/')+1);
$leftString = substr($str,0,strrpos($str,'/')+1);
$extension = substr($name,strrpos($name,'.'));
$nameNoExtension = substr($name,0,strrpos($name,'.'));
$string = $nameNoExtension.$suffix.$extension;
echo $leftString.$string;
//http://localhost/wine-works.co.uk-tester/wp-content/uploads/2013/09/canada-wine_shop-25x17.jpg

Answer 2

$d = pathinfo($productDetails['country'][0]['image']);
echo $new_name = $d['dirname'].'/'.$d['filename'].'-25x17.'.$d['extension'];
