There a times when you have an array and need to slit that array into smaller ones, I usually reach for explode or a foreach and do some custom coding but there is a far better way that’s built into PHP a function called array_chunk.
It accepts 3 parameters:
- The array of data
- The size of each chunk
- preserve keys – When set to TRUE keys will be preserved. Default is FALSE which will reindex the chunk numerically.
It’s perfect for this for instance take a look at this quick example:
//array of items $items = ['Book', 'Mobile', 'Laptop', 'Monitor', 'Keys', 'Cards']; //split the above array into multiple arrays containing 2 indexes in each. $parts = array_chunk($items, 2); //print out the results echo '<pre>'; print_r($parts); echo '</pre>'; Returns: Array (  => Array (  => Book  => Mobile )  => Array (  => Laptop  => Monitor )  => Array (  => Keys  => Cards ) )
