Quick Reference
The PHP touch() function sets the access and modification time of the specified file.
If the specified file does not exist, it will be created.
<?php
file = 'test.txt';
if (touch($file)) {
echo $file . ' modification time has been changed';
}
else {
echo $file . 'time could not be modified';
}
?>Output
// sets the access and modification time of the specified fileSyntax
touch(filename, time, atime)Parameters
| Parameter | Description |

| filename | Specifies the file to touch (required) |
| time | Sets the touch time (current system time is set by default) |
| atime | Sets the access time (default is the current system time if no parameters are set, or the same as the time parameter if that parameter is set) |
PHP Notes:
- When using PHP, single or double quotation marks are acceptable and work identically to one another; choose whichever you prefer, and stay consistent
- Arrays count starting from zero NOT one; so item 1 is position [0], item 2 is position [1], and item 3 is position [2] … and so on
We’d like to acknowledge that we learned a great deal of our coding from W3Schools and TutorialsPoint, borrowing heavily from their teaching process and excellent code examples. We highly recommend both sites to deepen your experience, and further your coding journey. We’re just hitting the basics here at 1SMARTchicken.
