Sort array by version number

[Joveice]

How can you sort an array based on it's version number?

 

the usort works fine, but I don't see how I can use it on my array.

 

array(
    array('id' => 1, 'version' => '1.3'),
    array('id' => 2, 'version' => '1.3.1'),
    array('id' => 3, 'version' => '1.3.2'),
    array('id' => 4, 'version' => '1.3.2-RC1'),
    array('id' => 5, 'version' => '1.3.2-RC2'),
);

I'm trying to get this order

1.3.2

1.3.2-RC2

1.3.2-RC1

1.3.1

1.3

 

how can I get this to work?

You probably will have to do something yourself if you want it to sort the way you do.

rsort(array, SORT_NUMERIC);

 

test example: 

<?php

$fruits = array("1", "2", "2-1", "2-2", "3", 1-1);
rsort($fruits, SORT_NUMERIC );

foreach ($fruits as $key => $val) {
    echo "fruits[" . $key . "] = " . $val . "\n";
}
 

output:

fruits[0] = 3
fruits[1] = 2
fruits[2] = 2-1
fruits[3] = 2-2
fruits[4] = 1
fruits[5] = 0

 

My array is multidimensional

[Joveice]

$array = array(
    '1.3',
    '1.3.1',
    '1.3.2',
    '1.3.2-RC1',
    '1.3.2-RC2',
);

usort($array, 'version_compare');
$array = array_reverse($array);
foreach ($array as $ccc) {
	echo $ccc.'<br>';
}

Output

1.3.2
1.3.2-RC2
1.3.2-RC1
1.3.1
1.3

But I can't do this with a multidimensional array.

You can add  SORT_NUMERIC as parameter to your sort function.

$array = array_reverse($array, SORT_NUMERIC);

 

Why?

[Joveice]

$array = array(
    array('id' => 1, 'version' => '1.3'),
    array('id' => 2, 'version' => '1.3.1'),
    array('id' => 3, 'version' => '1.3.2'),
    array('id' => 4, 'version' => '1.3.2-RC1'),
    array('id' => 5, 'version' => '1.3.2-RC2'),
);

usort($array, function($a,$b) {
    return -1 * version_compare ( $a['version'] , $b['version'] );
});

foreach ($array as $ccc) {
	echo $ccc['version'].'<br>';
}

output

1.3.2
1.3.2-RC2
1.3.2-RC1
1.3.1
1.3
