PHP implementation method of using continue to skip the remaining code in the loop

The continue jump statement is used to skip the statement specifying the condition in this loop and continue to execute other loop statements. As we all know, in PHP, continue is used in loop structures to skip the remaining code in this loop and start executing the next loop when the condition evaluates to true. It must be noted that when using continue, you must use ";" to separate other codes, otherwise it may cause errors!

continue Usage:

<?php
for ($n = 0; $n < 5; $n++) {
 if ($n == 2)
  continue;
  echo "$n\n";
}
?>

Output result:

0 1 3 4

Obviously, when $n is equal to 2, it is skipped The output is exactly what we want. If the semicolon is missing, an error will be reported!

Error code:

<?php
for ($n = 0; $n < 5; $n++) {
 if ($n == 2)
  continue
  echo "$n\n";
}
?>

Error message:

Parse error: syntax error, unexpected 'echo' (T_ECHO) in D:\phpStudy\WWW\demo\fun \continue.php on line 5

So note: when we use continue, we must be careful not to miss the semicolon!
