Things to note when php uses continue to skip the remaining code in this loop

continueThe jump statement is used to skip the statement that specifies the condition in this loop, and continue to execute other loop statements. The following article mainly introduces you to a point to note about using continue to skip the remaining code in this loop in PHP. The content in the article is relatively basic, and friends in need can refer to it. Let’s take a look together.

Preface

As we all know, in PHP, continue is used in the loop structure to skip the remaining code in this loop and The next iteration of the loop begins 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!

continueUsage:

<?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, the output is skipped, which 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!
