php loops

<?php
  
  /* There are 4 types of loops:
  1) while - loops through a block of code as long as the specified condition is true
  2) do...while - loops through a block of code once, and then repeats the loop as long as the specified condition is true
  3) for - loops through a block of code a specified number of times
  4) foreach - loops through a block of code for each element in an array
  */
  
  #While loop syntax
  
  while (condition is true) {
  code to be executed;
  }

  #While loop example
  <?php
  $x = 1;

  while($x <= 5) {
    echo "The number is: $x <br>";
    $x++;
  }

  #Do while loop syntax

  do {
  code to be executed;
  } while (condition is true);

  #Do while loop example

  $x = 1;

  do {
    echo "The number is: $x <br>";
    $x++;
  } while ($x <= 5);

  #For loop syntax

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

  for ($x = 0; $x <= 100; $x+=10) {
    echo "The number is: $x <br>";
  }

  #Foreach loop syntax

  foreach ($array as $value) {
    code to be executed;
  }

  #Foreach loop example

  $colors = array("red", "green", "blue", "yellow");

  foreach ($colors as $value) {
    echo "$value <br>";
  }

  #Break and continue

  #After break and continue, the lines after it are not executed

  #Continue:

  for ($x = 0; $x < 10; $x++) {
    if ($x == 4) {
      continue;
    }
    echo "The number is: $x <br>";
  }

  #Break:

  $x = 0;

  while($x < 10) {
    if ($x == 4) {
      break;
    }
    echo "The number is: $x <br>";
    $x++;
  }
?>

How to write a loop in PHP

<?php

//FOR each item within the array, "ECHO" out the index ($i) and value of each item.
$numbersArray = [1, 2, 3]
for($i = 0; $i < count($numbersArray); $i++) {
	echo "Index of ".$i."= ".$numbersArray[$i]."<br>";
}

?>
