PHP mkdir(): Create a Directory
The PHP mkdir() function is used when we need to create a new directory. For example:
<?php $dir = "Documents"; $chk = mkdir($dir); if($chk) echo "<p>A new directory is created</p>"; else echo "<p>Unable to create</p>"; ?>
Before executing the above PHP code, here is a snapshot of the current directory:
After executing the above PHP code or example, here is the output produced in the web browser:
And here is the new snapshot of the current directory after executing the above PHP code:
PHP mkdir() Syntax
The syntax of the mkdir() function in PHP is:
mkdir(directory, permissions, recursive, context)
The first (directory) parameter is required, whereas all the other three parameters are optional.
Note: The directory parameter is used to specify the directory to create.
Note: The permissions parameter is used to specify permission. The default value is 0777.
Note: The recursive parameter is used when we need to allow the creation of nested directories. The default value is false.
Note: The context parameter is used to specify the context resource. The default value is null.
The mkdir("xyz") is the same as mkdir("xyz", 0777, false, null).
Advantages of the mkdir() function in PHP
- mkdir() is a straightforward function that can create a new directory with a single line of code.
- mkdir() is a built-in PHP function that works on the vast majority of PHP-enabled servers, making it a dependable and portable way to create directories across platforms.
- If the directory was successfully created, mkdir() returns TRUE; otherwise, it returns FALSE. This enables you to handle errors and take appropriate actions based on the operation's success or failure.
- Because mkdir() can create directories recursively, you can create a new directory as well as all of its parent directories in a single call. When creating complex directory structures, this can save you time and effort.
Disadvantages of the mkdir() function in PHP
- Using mkdir() to create a new directory can cause permission problems if the user running the PHP script does not have the necessary permissions to create directories in the specified location.
- If an existing directory has the same name as the directory you're trying to create, mkdir() will overwrite it. If the existing directory contains important data, this can result in data loss.
- mkdir() only returns a Boolean value indicating success or failure and does not provide detailed error messages to assist you in diagnosing the cause of any errors that occur.
