Suppose you have a CMS which saves a list of phone numbers for each user. They are stored like this:
$phones['Home'] = '(555)555-1234';
$phones['Office'] = '(555)555-2222';
You only want to save to the database if the list of items has changed. Including if the ORDER of
them has changed.
<?php
// Compares two arrays- keys and values (as strings) must match.
// Keys and order must be the same to be equal.
function arraysEqual($arr1, $arr2){
if(count($arr1) != count($arr2)){
return(FALSE);
}else{
$arrStr1 = serialize($arr1);
$arrStr2 = serialize($arr2);
if( strcmp($arrStr1, $arrStr2)==0 ){
return(TRUE);
}else{
return(FALSE);
}
}
}
?>
