remove elements in array

[corics15]

hello everyone!

i have two arrays, for simplicity i have an example:

 

first array:
Array
(
    [0] => 370
    [1] => 368
    [2] => 424
    [3] => 496
    [4] => 307
)

second array:
Array
(
    [0] => 368
    [1] => 496
)

all i want is, remove the elements on the first array based from the second array, thus having:

final array:
Array
(
    [0] => 370
    [2] => 424
    [4] => 307
)

...please help me out...thanks...

Take a look at the function array_intersect

Take a look at the 'in_array()' function. Walk through your first array with a for each loop. Have it check to see if the current value exists in the second array. Throw the unique values into another array.

$arr1 = array(370, 368, 424, 496, 307);
$arr2 = array(368, 496);

foreach($arr2 as $v2) {
foreach($arr1 as $k => $v1) {
	if($v1 == $v2) {
		unset($arr1[$k]);
	}
}
}

$arr3 = array_values($arr1);
print_r($arr3);

use array_diff:

 

$new = array_diff($arr1, $arr2);

Go with array_diff as AlexWD says.

array_intersect will return what is found that matches the values of the second array. Not what you want.

in_array will only return a single key of the found value. Not what you want.

Note on array diff. It will diff multiple values. If you have the value of say"6" in 3 separate elements you will catch them all.

wrong choice you should have gone for AlexWD's solution. It's stupid to write something that is already built-in.

thanks ignace..no need to get furious. i also did AlexWD's solution.

I wasn't furious (bare in mind I'm not a native English speaker) I just pointed out that there is no need to write a function for something that already exists like when someone writes a function to get the extension of a filename instead of using pathinfo

lol, until recently i never even knew what basename() did. I'd split my urls into arrays and reverse em and take the first element as a new string. There are such useful inbuilt functions

Yeah like end which you clearly don't know either

[MatthewJ]

Yeah, I have never had a reason to use array_diff(), but it is obviously the better solution. I'm just happy the stupid code I wrote worked
