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 ) )
For the past 12 years, I’ve been developing applications for the web using mostly PHP. I do this for a living and love what I do as every day there is something new and exciting to learn.
In my spare time, the web development community is a big part of my life. Whether managing online programming groups and blogs or attending a conference, I find keeping involved helps me stay up to date. This is also my chance to give back to the community that helped me get started, a place I am proud to be apart of.
Besides programming I love spending time with friends and family and can often be found together going out catching the latest movie, staying in playing games on the sofa or planning a trip to someplace I’ve never been before.
