Split An Array Into Smaller Parts In PHP

Splitting an array into sections might be useful for setting up a calendar or pagination on a site. Either way there are numerous ways to do this but the following seems to be the quickest and most reliable method.

function sectionArray($array, $step)


{


 $sectioned = array();


 


 $k = 0;


 for ( $i=0;$i < count($array); $i++ ) {


  if ( !($i % $step) ) {


   $k++;


  }


  $sectioned[$k][] = $array[$i];


 }


 return $sectioned;


}

Run the function by passing it an array, in this case I am going to split the alphabet into 5 arrays of 5 letters.

$array = range('a','z'); // create an array from a to z


 


echo '<pre>'.print_r(ArraySplitIntoParts_Shorter($array,5),true).'</pre>';

This produces the following output.
