with an edit from the php array_dif example, here’s a nice comparison and removal script,

“green”, “red”, “blue”, “red”, “purple”);
$array2 = array(“b” => “green”, “yellow”, “red”);
$result = array_diff($array1, $array2);
$myray[] = implode(“,”,$result);
echo implode(“,”,$myray);
?>

I have used unset() on an array element to remove the element.

I like your solution!

@Cool, yes you can use a combo of array_filter with another helper to remove any elements with the letter ‘c’ from you array above. Here’s some sample code for your use case:

$array = array(‘abc’,'cde’,'efg’);

function hasNoC($val) {
return (stripos($val, ‘c’) === false);
}

$clean_array = array_filter($array, “hasNoC”);

For example,

$array = array(abc,cde, efg);

If i want to remove elements that match with character ‘c’ from an array like above,

can it be works by using array_filter() and preg_match()?

Coz from wat i see here is using function within it to remove the elements. so i need to put whole command in current function, right?

Please correct me if i’m wrong.

You may change your discussion title. It is too global.

Maybe with something like :

“Delete selected items from an array with conditions”

for people looking for unset or array_splice.
