wp_mkdir_p: 这个函数创建一个目录和任何必要的父目录(如果它们不存在)。它是mkdir函数的一个封装器,用于确保在创建文件或存储数据时必要的目录存在。

基于全路径的递归目录创建。

将尝试设置文件夹的权限。

function wp_mkdir_p( $target ) {
	$wrapper = null;

	// Strip the protocol.
	if ( wp_is_stream( $target ) ) {
		list( $wrapper, $target ) = explode( '://', $target, 2 );
	}

	// From php.net/mkdir user contributed notes.
	$target = str_replace( '//', '/', $target );

	// Put the wrapper back on the target.
	if ( null !== $wrapper ) {
		$target = $wrapper . '://' . $target;
	}

	/*
	 * Safe mode fails with a trailing slash under certain PHP versions.
	 * Use rtrim() instead of untrailingslashit to avoid formatting.php dependency.
	 */
	$target = rtrim( $target, '/' );
	if ( empty( $target ) ) {
		$target = '/';
	}

	if ( file_exists( $target ) ) {
		return @is_dir( $target );
	}

	// Do not allow path traversals.
	if ( false !== strpos( $target, '../' ) || false !== strpos( $target, '..' . DIRECTORY_SEPARATOR ) ) {
		return false;
	}

	// We need to find the permissions of the parent folder that exists and inherit that.
	$target_parent = dirname( $target );
	while ( '.' !== $target_parent && ! is_dir( $target_parent ) && dirname( $target_parent ) !== $target_parent ) {
		$target_parent = dirname( $target_parent );
	}

	// Get the permission bits.
	$stat = @stat( $target_parent );
	if ( $stat ) {
		$dir_perms = $stat['mode'] & 0007777;
	} else {
		$dir_perms = 0777;
	}

	if ( @mkdir( $target, $dir_perms, true ) ) {

		/*
		 * If a umask is set that modifies $dir_perms, we'll have to re-set
		 * the $dir_perms correctly with chmod()
		 */
		if ( ( $dir_perms & ~umask() ) != $dir_perms ) {
			$folder_parts = explode( '/', substr( $target, strlen( $target_parent ) + 1 ) );
			for ( $i = 1, $c = count( $folder_parts ); $i <= $c; $i++ ) {
				chmod( $target_parent . '/' . implode( '/', array_slice( $folder_parts, 0, $i ) ), $dir_perms );
