The tempnam Function
The tempnam function creates a temporary file with a unique name in the specified directory. The first parameter of the function is the path to the directory, the second is the prefix for the filename. The function returns the path to the created file or false on error.
Syntax
tempnam(directory, prefix);
Example
Let's create a temporary file in the system temporary directory with the prefix 'my':
<?php
$res = tempnam(sys_get_temp_dir(), 'my');
echo $res;
?>
Code execution result (example):
'/tmp/my5d3b7f2e'
Example
Let's create a temporary file in the current directory:
<?php
$res = tempnam(__DIR__, 'temp');
echo $res;
?>
Code execution result (example):
'/var/www/project/temp5d3b7f2f'
Example
Let's check the function's operation with a non-existent directory:
<?php
$res = tempnam('/nonexistent', 'test');
var_dump($res);
?>
Code execution result:
false
