PHP two-dimensional array sorting

$arr = Array (
Array (' desc ' = ' pic13.jpg '),
Array (' desc ' = ' pic18.jpg '),
Array (' desc ' = ' pic21.jpg '),
Array (' desc ' = ' pic22.jpg '),
Array (' desc ' = ' pic23.jpg '),
Array (' desc ' = ' pic5.jpg '),
Array (' desc ' = ' pic6.jpg '),
Array (' desc ' = ' pic7.jpg '),
Array (' desc ' = ' pic8.jpg '),
Array (' desc ' = ' pic9.jpg '),
);

The desc of the array is sorted in order, with values from small to large.

The original two-dimensional array is such that it needs to be displayed after sorting.

PHP Code?123456789101112131415$arr = array (' desc ' = ' pic13.jpg '), array (' desc ' = ' pic18.jpg '), Array (' d Esc ' = ' pic21.jpg '), array (' desc ' = ' pic22.jpg '), array (' desc ' ...

The original interception is also calculated Ah, it seems that the PHP developer has done a lot of matching this function ah

Isn't that the same thing?

Isn't that the same thing?

Is the reason for my own procedures, thank you boss ~ ~ ~

Isn't there an array sort function?
