What are loops in PHP?

Like other languages, PHP has loops. PHP loops are used to execute a statement or a block of statements multiple times according to a specific condition.

Why do you use loops?

Loops are helped the user save the effort of writing the same code multiple times, and it also saves the time of the user.

The following two examples have the same output.

1) Without using Loop – Echo all array values.

  $names = array('James','Mark','John','Barry','Bruce','Joe');

  echo $names[0].'<br>';
  echo $names[1].'<br>';
  echo $names[2].'<br>';
  echo $names[3].'<br>';
  echo $names[4].'<br>';
  echo $names[5].'<br>';

2) Using Loop – Echo all array values

  $names = array('James','Mark','John','Barry','Bruce','Joe');

  foreach($names as $single_name){
      echo $single_name.'<br>';
