function System::mktemp

Creates temporary files or directories. This function will remove the created files when the scripts finish its execution.

Usage: 1) $tempfile = System::mktemp("prefix"); 2) $tempdir = System::mktemp("-d prefix"); 3) $tempfile = System::mktemp(); 4) $tempfile = System::mktemp("-t /var/tmp prefix");

prefix -> The string that will be prepended to the temp name (defaults to "tmp"). -d -> A temporary dir will be created instead of a file. -t -> The target dir where the temporary (file|dir) will be created. If this param is missing by default the env vars TMP on Windows or TMPDIR in Unix will be used. If these vars are also missing c:\windows\temp or /tmp will be used.

Parameters

Return value

mixed the full path of the created (file|dir) or false
