Replace the strnatcasecmp() call with whatever sorting mechanism you prefer. Note the use of single quotes in the create_function() args so that variables are not interpolated during compilation.@NogDogMay 29.2011 — #
Well, an array in PHP is, in effect, a (singly) linked list, since it is easily traversable in a repeatable manner via foreach() or next(). All we're doing with the usort() is changing the linkage between elements. Unless you have a functional requirement to be able to know what the next/prior element is for any arbitrarily chosen array element (i.e. foreach() or next() will not suffice), then I see no need for added complexity. :p
How do I sort an array of objects by the object’s property?
I have an array of objects, the objects all have a property with an integer value. I want to sort the array by the value of the property of the object.
I did some searching and found usort(). It’s very confusing for me. Is there a simple function that I can use to sort the array?

usort(
$array,
create_function(
'$obj1, $obj2',
'return strnatcasecmp($obj1->varName, $obj2->varName);'
)
);

Just saying ?[/QUOTE]
