how to skip elements in foreach loop

Five solutions come to mind:

Double addressing via array_keys

The problem with for loops is that the keys may be strings or not continues numbers therefore you must use "double addressing" (or "table lookup", call it whatever you want) and access the array via an array of it's keys.

// Initialize 25 items$array = range( 1, 25, 1);// You need to get array keys because it may be associative array// Or it it will contain keys 0,1,2,5,6...// If you have indexes staring from zero and continuous (eg. from db->fetch_all)// you can just omit this$keys = array_keys($array);for( $i = 21; $i < 25; $i++){    echo $array[ $keys[ $i]] . "\n";    // echo $array[$i] . "\n"; // with continuous numeric keys}

Skipping records with foreach

I don't believe that this is a good way to do this (except the case that you have LARGE arrays and slicing it or generating array of keys would use large amount of memory, which 68 is definitively not), but maybe it'll work: :)

$i = 0;foreach( $array as $key => $item){    if( $i++ < 21){        continue;    }    echo $item . "\n";}

Using array slice to get sub part or array

Just get piece of array and use it in normal foreach loop.

$sub = array_slice( $array, 21, null, true);foreach( $sub as $key => $item){    echo $item . "\n";}

Using next()

If you could set up internal array pointer to 21 (let's say in previous foreach loop with break inside, $array[21] doesn't work, I've checked :P) you could do this (won't work if data in array === false):

while( ($row = next( $array)) !== false){  echo $row;}

_{btw: I like hakre's answer most.}

Using ArrayIterator

Probably studying documentation is the best comment for this one.

// Initialize array iterator$obj = new ArrayIterator( $array);$obj->seek(21); // Set to right positionwhile( $obj->valid()){ // Whether we do have valid offset right now    echo $obj->current() . "\n";    $obj->next(); // Switch to next object}

$i = 0;foreach ($query){  if ($i++ < 20) continue;  /* php code to execute if record 21+ */}

if want to skipped some index then make an array with skipped index and check by in_array function inside the foreach loop if match then it will be skip.

Example:

//you have an array like that$data = array(    '1' => 'Hello world',    '2' => 'Hello world2',    '3' => 'Hello world3',    '4' => 'Hello world4',    '5' => 'Hello world5',// you want to skip this    '6' => 'Hello world6',// you want to skip this    '7' => 'Hello world7',    '8' => 'Hello world8',    '9' => 'Hello world8',    '10' => 'Hello world8',//you want to skip this);//Ok Now wi make an array which contain the index wich have to skipped$skipped = array('5', '6', '10');foreach($data as $key => $value){    if(in_array($key, $skipped)){        continue;    }    //do your stuf}
