how to skip elements in foreach loop

Question

I want to skip some records in a foreach loop.

For example, there are 68 records in the loop. How can I skip 20 records and start from record #21?

Answer 1

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
}
