Example of how to delete a directory and all files in php

/**
* Loop delete directory and file function
* @delDirAndFile
* @param $dirName
* @edit bbs.it-home.org
function delDirAndFile( $dirName )
{
if ( $handle = opendir( "$dirName" ) ) {
while ( false !== ( $item = readdir( $handle ) ) ) {
if ( $item != "." && $item != ".." ) {
if ( is_dir( "$ dirName/$item" ) ) {
delDirAndFile( "$dirName/$item" );
} else {
if( unlink( "$dirName/$item" ) ) echo "File deleted successfully: $dirName/$item
 n";
}
}
}
closedir( $handle );
if( rmdir( $dirName ) ) echo "Directory deleted successfully: $dirName
n";
}
}
?>

Function 2, only deletes files in the specified directory, not the directory folder.

/**
 * Loop all files in the directory
 * @func delFileUnderDir
 * @param $dirName
 * @edit bbs.it-home.org
*/
function delFileUnderDir( $dirName )
{
if ( $handle = opendir( "$dirName" ) ) {
while ( false !== ( $item = readdir( $handle ) ) ) {
if ( $item != "." && $item != ".." ) {
if ( is_dir( "$dirName/$item" ) ) {
delFileUnderDir( "$dirName/$item" );
} else {
if( unlink( "$dirName/$item" ) ) echo "File deleted successfully: $dirName/$item
n";
}
}
}
closedir ( $handle );
}
}
?>

Let’s look at the specific calling example. 1. Delete a sibling directory named "upload", that is, all files in this directory:

delDirAndFile( 'upload');
?>

2, delete all files in a directory named "upload" (but there is no need to delete the directory file folder):

delFileUnderDir( 'upload');
?>
