PHP Question

Rename Directory using PHP Script

I have a directory containing folders like


baseurl/2-435435435_323423/

baseurl/5_435435435_32423/

baseurl/3_543543543_2342342/


Now i want to rename all the folders from their original name to new name i.e. truncate last part separated by '_'. new names would be



baseurl/2-435435435/

baseurl/5_435435435/

baseurl/3_543543543/


$path_from = 'E:/documents/';
if(file_exists($path_from)){
$files = scandir($path_from);
foreach($files as $key1 => $file) {
$newName = ? // I need this
rename($path_from.$file,$path_from.$newName);
}
}


Or Let me know if there is anyway in windows to rename batch without any script.

Answer

As you mention for getting only $newName, Just use substr and strrpos.

strrpos - Find the numeric position of the last occurrence of a string

$str = 'baseurl/3_543543543_2342342/';

$pos = strrpos($str, "_");
if ($pos === false){
    //do nothing
}else
    $str = substr($str, 0, $pos)."/";

echo $newName = $str; //baseurl/3_543543543/
