In a PHP for loop, the three expressions are typically used to set the initial value of a counter variable, provide the condition that the loop should end, and modify the counter variable. The initial value expression sets the starting point of the counter variable, the condition expression determines when the loop should end, and the modification expression updates the counter variable after each iteration. These expressions work together to control the loop's flow and determine how many times the loop executes the code block. Learn more: https://www.php.net/manual/en/control-structures.for.php
