➤ The for loop is used when you know in advance how many times the script should run.

for (init counter; test counter; increment counter) {
  code to be executed for each iteration;
}

➤ Parameters (divided by ; ): • init counter: Initialize the loop counter value • test counter: Evaluated for each loop iteration. If it evaluates to TRUE, the loop continues. If it evaluates to FALSE, the loop ends. • increment counter: Increases the loop counter value For instance:

// outputs the numbers from 1 to 10
for ($i = 0; $i <= 10; $i++) {
  echo "The number is: $i \n";
} 

// Without first parameter
$i = 0;
for (; $i <= 10; $i++) {
  echo "The number is: $i \n";
} // outputs the numbers from 1 to 10

// Without first and third parameter
$i = 0;
for (; $i <= 10;) {
  echo "The number is: $i \n";
  $i++; // we got the while loop syntax :))
} // outputs the numbers from 1 to 10

// We can make a for loop infinite without using these three parameters
for ( ; ; ){
	echo "infinite \n";
}
