How to offset the start in a foreach loop?

Question

I want my foreach starts of ex : $Element = 10 up to 20

At the moment :

foreach($lang['tech'] as $Element => $ElementName)
    {
       $parse['tt_name'] = $ElementName; // Displays the name

       if($Element > 99) // At over 99 foreach stop
       {
           break;  
       }
    }

I wish I had this principle in :

foreach($lang['tech'] as **$Element(10 to 20)** => $ElementName) // Display Element 10 to 20
    {
       $parse['tt_name'] = $ElementName; // Displays the name
    }

Thanks for your help

why you are not using simple for loop instead of foreach? — Pepo_rasta

for ($i = 10; $i <= 20; $i++) { $parse['tt_name'] = $lang['tech'][$i]; } ? — mhall

If i understand you correct you want to loop only element 10 to 20, you could use a for loop

for($i = 10; $i <= 20;$i++) {
    $entry = $lang['tech'][$i];
    // do something
}

You could use continue:

foreach($lang['tech' as $Element => $ElementName)
{
   if($Element < 10) // Less than 10 - skip!
   {
       continue;  
   }

   $parse['tt_name'] = $ElementName; // Displays the name

   if($Element > 99) // At over 99 foreach stop
   {
       break;  
   }
}

Or you could use for loop:

for ($Element=10; $Element<=99; $Element++) {
    $ElementName = $lang['tech'][$Element];
}

you missed ] in your foreach loop

foreach($lang['tech'] as $Element => $ElementName)
                    ^

You're missing ] in two places in your example code:

foreach($lang['tech'] as $Element => $ElementName)
                    ^

and

foreach($lang['tech'] as **$Element(10 to 20)** => $ElementName)
                    ^

You can filter it before iterating:

$tech = array_filter($lang['tech'], function($key) {
    return $key >= 10 && $key <= 20;
}, ARRAY_FILTER_USE_KEY);

foreach ($tech as $key => $name) {
    // do what you need
}

Probably because of the PHP version :)

You can loop into the subarray :

foreach( array_slice ($yourarray , 10, 10) as $Element) {
...
}
