How can i Sort Multidimensional array using PHP??

hi,

An array in PHP is actually an ordered map. A map is a type that associates values to keys. This type is optimized for several different uses; it can be treated as an array, list (vector), hash table (an implementation of a map), dictionary, collection, stack, queue, and probably more. As array values can be other arrays, trees and multidimensional arrays are also possible.

array('comment','1234567893','fghj','mjktyu'),
array('article','1234567891','cvmo','pjklgg'),
array('news','1234567894','qwenb','asbhtyhj'),
);

$sort_field = 3; // enter the number of field to sort

// compare function
function cmpi($a, $b)
{
global $sort_field;
return strcmp($a[$sort_field], $b[$sort_field]);
}

// do the array sorting
usort($latest_array, 'cmpi');

// demo output

PHP identify how to evaluate two numbers or two text strings, but in a multidimensional array, each element is an array. PHP provides many utility to sort an array.

Hi,
Once the PHP array can store all information (strings, numbers, objects, arrays, boolean). We use an array to save the text (string). Tables store data using a key - on a subscription basis. Key is the place we saved the text string. The value is the actual text that we want to keep.
Thanks.
