How to sort an array of arrays in php?

How can I sort an array like: $array[$i]['title'];

Array structure might be like:

array[0] (   'id' => 321,   'title' => 'Some Title',   'slug' => 'some-title',   'author' => 'Some Author',   'author_slug' => 'some-author' );  array[1] (   'id' => 123,   'title' => 'Another Title',   'slug' => 'another-title',   'author' => 'Another Author',   'author_slug' => 'another-author' ); 

So data is displayed in ASC order based off the title field in the array?

Answer 1

Use usort which is built explicitly for this purpose.

function cmp($a, $b) {     return strcmp($a["title"], $b["title"]); }  usort($array, "cmp");
