Rename a large number of pictures

There are 1,000 pictures in the img folder. How do I change the names of these 1,000 pictures from 1 to 1,000? ? ? ?

<code>$arr = glob("img/*.jpg");
var_dump($arr);
$i = 1;
foreach($arr as $file) {
    // 获取图片后缀名
    $ext = pathinfo($file,PATHINFO_EXTENSION);
    $name = $i++ . "." . $ext;
    // 重命名 
    rename($file, $name);
}
</code>

You can use bash. Assuming that your php is running under Linux and you have bash, you can do something similar: shell_exec("i=1;for file in /path/to/img; do mv $file $i; i=$i 1; done")

Of course there is actually a function in php called rename: rename php manual, you can:

<code>$arr = scandir("/path/to/img");
$i = 1;
foreach($arr as $file) {
    rename($file, $i++);
}
</code>

Just pay attention to the php version.

<code>// 获取图片列表
$arr = scandir("/path/to/img");
$i = 1;
foreach($arr as $file) {
    // 获取图片后缀名
    $ext = pathinfo($file,PATHINFO_EXTENSION);
    $name = $i++ . "." . $ext;
    // 重命名 
    rename($file, $name);
}

I recommend you take a look at what Zhang Xinxu wrote not long ago. What can you do with js for general web page reconstruction?
The above example uses nodejs to batch change names
