Sorting an array of objects

[The14thGOD]

Is there a way to sort an array of objects by the objects variable name or a property within the object?

I'm new to OOP so sorry if this is dumb.

 

<?php
//example code
$members = array();
$member_name = 'John Doe';
$member_last_name = 'Doe';
$_GET['filter'] == 'alpha' ? $array_safe_name = str_replace(' ','_',$member_last_name) : $array_safe_name = str_replace(' ','_',$member_name);									
$array_safe_name = str_replace('.','',$array_safe_name);
$array_safe_name = str_replace("'",'',$array_safe_name);
${$array_safe_name} = new njl_member($member_name,$member_title,$member_image,$member_phone,get_permalink());
array_push($members,${$array_safe_name});

foreach($members as $member){
//do stuff
}
?>

ksort/asort obviously wont work (as far as I know them....)

 

So if I have 'John Doe', 'Joe Adams', 'Jane Smith', I'd like the foreach to display them

Joe Adams

John Doe

Jane Smith

 

Thanks for any and all help,

Justin
