Question

I wanted to check to enter data into the database.Checks are as follows

$implode1 = "cat, dog, chicken";

$implode2 = "cow, goat, cat";

If the cat in the variable $implode1 is also contained in the variable $implode2, it should display a warning message. How to code for the above problem?

Help me please 🙁

Answer 1

You could explode your strings to arrays, then use array_intersect to return the values which are present in both, eg:

$string1 = 'cat, dog, chicken';
$string2 = 'cow, goat, cat';

$compare = explode(', ', $string1);
$against = explode(', ', $string2);

$matches = array_intersect($compare, $against);
