PHP Continue Example with for loop

Example

In the following example, we will print only those values of i and j that are same and skip others.

1. <?php  
2.     //outer loop  
3.     for ($i =1; $i<=3; $i++) {  
4.         //inner loop  
5.         for ($j=1; $j<=3; $j++) {  
6.             if (!($i == $j) ) {  
7.                 continue;       //skip when i and j does not have same values  
8.             }  
9.             echo $i.$j;  
10.             echo "</br>";  
11.         }  
12.     }  
13. ?>  

Output:

PHP continue Example in while loop

Example

In the following example, we will print the even numbers between 1 to 20.

1. <?php  
2.     //php program to demonstrate the use of continue statement  
3.   
4.     echo "Even numbers between 1 to 20: </br>";  
5.     $i = 1;  
6.     while ($i<=20) {  
7.         if ($i %2 == 1) {  
8.             $i++;  
9.             continue;   //here it will skip rest of statements  
10.         }  
11.         echo $i;  
12.         echo "</br>";  
13.         $i++;  
14.     }     
15. ?>  

Output:

Even numbers between 1 to 20:2468101214161820

PHP continue Example with array of string

Example

PHP continue Example with optional argument

The continue statement accepts an optional numeric value, which is used accordingly. The numeric value describes how many nested structures it will exit.

Example

Look at the below example to understand it better:

1. <?php  
2.     //outer loop  
3.     for ($i =1; $i<=3; $i++) {  
4.         //inner loop  
5.         for ($j=1; $j<=3; $j++) {  
6.             if (($i == $j) ) {      //skip when i and j have same values  
7.                 continue 1;     //exit only from inner for loop   
8.             }  
9.             echo $i.$j;  
10.             echo "</br>";  
11.         }  
12.     }     
13. ?>  

Output:
