Limit foreach?

jonzy

I'm wondering if I can limit a foreach statement?

my code is to pull links from an html page, but I would like to limit the results to the first 10 instead of all links found.

if(preg_match_all("/$regexp/siU", $file, $matches, PREG_SET_ORDER)) { 
foreach($matches as $match) { 

echo $match[2];
echo $match[3];

} 
}

Thanks for any help you can provide.

One way is to use a counter to determine when to break from within the loop. Another way is to use array_slice() to reduce the array to a maximum of ten elements.

One way:

$counter = 0;
foreach($matches as $match)
{
   // do stuff, then...
   if ++$counter >= 10 {
      break;
   }
}

Another way:

for($i=1, $max = min(10, count($matches)); $i <= $max; $i++)
{
   $match = next($matches);
   // do stuff with $match....
}

If you're not sure the array pointer is at the first element before starting the loop, do a reset($matches) first.

PS: Another way: use array_slice(). 🙂

Another:

foreach(array_slice($matches, 0, 10) as $match)
{...}
