Help with sorting a 2 dimensional array

I have an array that looks like this:

Array
(
    [0] => stdClass Object
        (
            [id] => 23
            [parent_id] => 0
            [title] => FELA KUTI
        )

    [1] => stdClass Object
        (
            [id] => 24
            [parent_id] => 0
            [title] => STEPHAN MICUS
        )

    [2] => stdClass Object
        (
            [id] => 25
            [parent_id] => 0
            [title] => JOHN LEE HOOKER
        )

)

Code (markup):

And I need to sort it alphabetically by the title. How can I do that?
Thanks for any help.

 

<?php
$array		= array(
	(object) array(
		'id'		=> 23,
		'parent_id'	=> 0,
		'title'		=> "FELA KUTI"
	),
	
	(object) array(
		'id'		=> 24,
		'parent_id'	=> 0,
		'title'		=> "STEPHAN MICUS"
	),
	
	(object) array(
		'id'		=> 25,
		'parent_id'	=> 0,
		'title'		=> "JOHN LEE HOOKER"
	)
);

$temp		= array();
$sorted 	= array();

foreach($array as $object)
	$temp[$object->title] = $object;
	
ksort($temp, SORT_STRING);

foreach($temp as $title => $object)
	$sorted[] = $object;
	
print_r($sorted);

Thanks a million, making the title the index of an array was the part I needed. I'm not very familiar with php syntax, can you tell me the difference between => and ->

 

Well, when dealing with objects (either accessing an object's property or method) the syntax is $object->property / $object->method($arg1, ...). Off the top of my mind, I think that this is the only occasion when you use -> in PHP.

In PHP you may create an array and immediately add some values to it, by writing something like this:

$var = array( 'key' => 'value');
    echo $var['key'];    // Echos 'value'

PHP:

The foreach control structure may also make use of the symbol =>:

foreach (array_expression as $key => $value)
    statement

Code (markup):

BTW, here's an alternative solution for your problem, a bit more elegant than the one I've posted above :

<?php
$array		= array(
	(object) array(
		'id'		=> 23,
		'parent_id'	=> 0,
		'title'		=> "FELA KUTI"
	),
	
	(object) array(
		'id'		=> 24,
		'parent_id'	=> 0,
		'title'		=> "STEPHAN MICUS"
	),
	
	(object) array(
		'id'		=> 25,
		'parent_id'	=> 0,
		'title'		=> "JOHN LEE HOOKER"
	)
);

usort($array, "myComparison");

function myComparison($obj1, $obj2)
{
	return strcasecmp($obj1->title, $obj2->title);
}
