Below we combine simple code examples to introduce how to obtain the directory path of temporary files in PHP.

<?php
$temp_file = tempnam(sys_get_temp_dir(), &#39;aaa&#39;);

echo $temp_file."\n";

The output is as follows:

Function introduction:

The tempnam() function is used to create a file with a unique file name.

tempnam ( string $dir , string $prefix ) : string

Create a file with a unique file name in the specified directory. If the directory does not exist, tempnam() generates a file in the system temporary directory and returns its filename.

The parameter dir indicates the directory in which the temporary file name will be created, and prefix indicates the prefix of the temporary file.

Note: Windows only uses the first three characters of the prefix.

The return value returns the new temporary file name, and returns FALSE on error.

sys_get_temp_dir() function Returns the directory used for temporary files

sys_get_temp_dir ( void ) : string

Returns the path to the default directory where PHP stores temporary files.

Return value returns the path of the temporary directory.
