Sort array of objects by object fields
Use usort, here's an example adapted from the manual:
function cmp($a, $b) {
return strcmp($a->name, $b->name);
}
usort($your_data, "cmp");
You can also use any callable as the second argument. Here are some examples:
Using anonymous functions (from PHP 5.3)
usort($your_data, function($a, $b) {return strcmp($a->name, $b->name);});
From inside a class
usort($your_data, array($this, "cmp")); // "cmp" should be a method in the class
Using arrow functions (from PHP 7.4)
usort($your_data, fn($a, $b) => strcmp($a->name, $b->name));
Also, if you're comparing numeric values, fn($a, $b) => $a->count - $b->count
as the "compare" function should do the trick, or, if you want yet another way of doing the same thing, starting from PHP 7 you can use the Spaceship operator, like this: fn($a, $b) => $a->count <=> $b->count
.
Heres a nicer way using closures
usort($your_data, function($a, $b)
{
return strcmp($a->name, $b->name);
});
Please note this is not in PHP's documentation but if you using 5.3+ closures are supported where callable arguments can be provided.
If you want to sort integer values:
// Desc sort
usort($array,function($first,$second){
return $first->number < $second->number;
});
// Asc sort
usort($array,function($first,$second){
return $first->number > $second->number;
});
UPDATED with the string don't forget to convert to the same register (upper or lower)
// Desc sort
usort($array,function($first,$second){
return strtolower($first->text) < strtolower($second->text);
});
// Asc sort
usort($array,function($first,$second){
return strtolower($first->text) > strtolower($second->text);
});
