How To Number an Array in FOREACH Loop

If you want to number a list of items from an array like this:

You may use the index number of an array to do the numbering with foreach. The simplest syntax is as such:

 $i = 0;
 foreach ($arr as $value) {
     echo $i++;
     echo $value;
 }

You can retrieve the value one at a time.

The other syntax can retrieve the real index number, if there were no literal keys in the array.

 foreach ($arr as $idx => $value) {
     echo $idx + 1;
     echo $value;
 }

It can be very flexible to design your web page. But don't forget that the starting index number of an array is 0.
