Hi,
To search an array for anything that match another array I'm doing this:
$array1 = array(array()); //I put value in here not shown
$array2 = array(array()); //I put value in here not shown
$position1 = 0;
foreach ( $array1 as $value ){
$position2 = 0;
foreach($array2 as $value2 ){
if ( $array1[$position1]['id'] == $array2[$position2]['id']){
$array1[$position2]['answer'] =
$array2[$position2]['answer'];
$array1[$position2]['remote_address'] =
$array2[$position2]
['remote_address'];
$$array1[$position2]['date_time'] =
$array2[$position2]['date_time'];
} //end ID match test
$position2++;
} //end pre loop
$position1++;
}// end array search
So this lets me search one array for any instance match in another.
Is there a better way to do this?
Now how to sort the results in $array1 by $array1[]['answer'] ??
Sincerely,
Mike
