tmpfile — Creates a temporary file
Description
tmpfile(): resource|false
Creates a temporary file with a unique name in read-write (w+) mode and returns a file handle.
The file is automatically removed when closed (for example, by calling fclose(), or when there are no remaining references to the file handle returned by tmpfile()), or when the script ends.
Caution
If the script terminates unexpectedly, the temporary file may not be deleted.
Parameters
This function has no parameters.
Return Values
Returns a file handle, similar to the one returned by
fopen(), for the new file or false on failure.
Examples
Example #1 tmpfile() example
<?php
$temp = tmpfile();
fwrite($temp, "writing to tempfile");
fseek($temp, 0);
echo fread($temp, 1024);
fclose($temp); // this removes the file
?>
The above example will output:
writing to tempfile
