How to go to next record in foreach loop

Question

In the following code, if $getd[0] is empty, I want to go to the next record.

foreach ($arr as $a1) {   $getd = explode(',' ,$a1);   $b1 = $getd[0]; } 

How can I achieve it?

Answer 1

We can use an if statement to only cause something to happen if $getd[0] is not empty.

foreach ($arr as $a1) {     $getd=explode(",",$a1);     if (!empty($getd[0])) {         $b1=$getd[0];     } } 

Alternatively, we can use the continue keyword to skip to the next iteration if $getd[0] is empty.

foreach ($arr as $a1) {     $getd=explode(",",$a1);     if (empty($getd[0])) {         continue;     }     $b1=$getd[0]; } 

Answer 2

Using continue which will skip to the next iteration of the loop.

foreach ($arr as $a1){     $getd=explode(",",$a1);       if(empty($getd[0])){         continue;     }      $b1=$getd[0];  }
