Hello folks! welcome back to a new edition of our tutorial on PHP. In this tutorial guide, we are going to be studying about the PHP tmpfile() Function.

The built-in PHP tmpfile() function is used for creating a temporary file with a unique name in the read-write (w+) mode.
Syntax
Following below is the syntax to use this function -
resource tmpfile ( void )
READ: PHP | symlink() Function
This function creates a temporary file with a unique name in the read-write (w+) mode and then returns a filehandle. The file is automatically removed when it is closed (for example by calling the fclose() function or when there are no remaining references to the filehandle returned by tmpfile()), or when the script ends.
Return Value
This function returns the filehandle similar to the one returned by the fopen() function for the new file, or false on failure.
Example
Try out the below example -
<?php $temp = tmpfile(); fwrite($temp, "Webdesigntutorialz!!!!"); rewind($temp); // Rewind to start of a file echo fread($temp, 1024); // Read 1k from a file fclose($temp); // it removes the file ?>
Output
When the above code is executed, it will produce the following result -
Webdesigntutorialz!!!!
