Use cases of continue in php

This article mainly introduces the use cases of continue in php. Interested friends can refer to it. I hope it will be helpful to everyone.

The key to using continue in PHP is to clearly distinguish the levels of the loop structure:

continue is used in the loop structure to skip the remaining code in this loop and evaluate the condition as When true, start executing the next loop. For example:

<?php  
    $i=0;  
    while($i<5)  
    {  
      if($i==2)  
       {  
         continue;  
       }  
      echo "$i<br>";  
      $i++;  
    }    
>

When $i is 2, it will jump out of the loop and execute the next loop. The output is:

0  
1  
3  
4

continue accepts an optional numeric parameter to determine how many loops to skip to the end of the loop. The default value is 1, which jumps to the end of the current loop.

 <?php  
for($m=0; $m <5; $m++)  
{   
     for($i=0; $i <5; $i++)  
     {  

        if($i > 3)  
        {  
          continue 2;          
       }  
       echo "$i    $m    <br>";  
     }  


 }  
?>

The result is

1 0   
2 0   
3 0   
0 1   
1 1   
2 1   
3 1   
0 2   
1 2   
2 2   
3 2   
0 3   
1 3   
2 3   
3 3   
0 4   
1 4   
2 4   
3 4
