Quick Reference
The PHP file_put_contents() writes data to a file.
This function follows these rules when accessing a file:
- If FILE_USE_INCLUDE_PATH is set, check the include path for a copy of filename
- Create the file if it does not exist
- Open the file
- Lock the file if LOCK_EX is set
- If FILE_APPEND is set, move to the end of the file. Otherwise, clear the file content
- Write the data into the file
- Close the file and release any locks
<?php
echo file_put_contents('test.txt', 'Hello World!');
?>
Output
// writes data to a file

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
