Hi there, i have been trying different methods and i wonder if somebody could explain to me how i would perform a comparison on two arrays for example
I have two arrays above, and i want to something like this
the code above does not work, but hopefully, you'll get from it the general idea of what im trying to do.. the line that is bugging me is the one directly under the "for" statement ....i know that line is screwed but i cant seem to work out how to test the existence of the $name variable in the other array
its probably a really simple fix to my above code but any help on this would be greatly appreciated

Is there anyway that I can compare two Arrays to see if any new strings have been added in them? eg:
Array 1: Joe Bob Jane
Array 2: Joe Bob Jane Greg
It would then output a new array with the changes:
Array 3: Greg

LEARN ABOUT PHP
array_intersect_assoc
ARRAY_INTERSECT_ASSOC(3) 1 ARRAY_INTERSECT_ASSOC(3)array_intersect_assoc - Computes the intersection of arrays with additional index checkSYNOPSIS
array array_intersect_assoc (array $array1, array $array2, [array $...])
DESCRIPTION array_intersect_assoc(3) returns an array containing all the values of $array1 that are present in all the arguments. Note that the keys
are used in the comparison unlike in array_intersect(3).
PARAMETERS
o $array1
- The array with master values to check.
o $array2
- An array to compare values against.
o $...
- A variable list of arrays to compare.
RETURN VALUES
Returns an associative array containing all the values in $array1 that are present in all of the arguments.
EXAMPLES
Example #1
array_intersect_assoc(3) example
<?php
$array1 = array("a" => "green", "b" => "brown", "c" => "blue", "red");
$array2 = array("a" => "green", "b" => "yellow", "blue", "red");
$result_array = array_intersect_assoc($array1, $array2);
print_r($result_array);
?>
The above example will output:
Array
(
[a] => green
)
In our example you see that only the pair "a" => "green" is present in both arrays and thus is returned. The value "red" is not returned
because in $array1 its key is 0 while the key of "red" in $array2 is 1, and the key "b" is not returned because its values are different in
each array.
The two values from the key => value pairs are considered equal only if (string) $elem1 === (string) $elem2 . In other words a strict type
check is executed so the string representation must be the same.
