Question

I’m trying to achieve the following

I have post data which is an array[]

I’m using a foreach to run through the array

foreach($images as $image){

  update_option( 'image-'. $mycounter .'', $image );

}

I need $mycounter to be counting as it runs through the foreach. How can I achieve that. I tried it with a while loop but not working 🙁

Thanks

You could use the incrementing operator:

$mycounter = 0;

foreach($images as $image){

  update_option( 'image-'. $mycounter .'', $image );
  $mycounter++; // increments through each iteration

}

OR use the unique numerical indices as your counter, assuming the indices are numerical.

foreach($images as $index => $image){

  update_option( 'image-'. $index .'', $image );

}
