how do you continue a loop that an iteration has failed but still want the remaining part of the loop to be run.



$arr = [1, 2, 3, 4];



foreach($arr as $val) {

    if($val == 2) {

        throw new Exception('Value = 2');

    }



    try {

        echo $val;

    }

    catch(Execption $e) {

        echo $e;

    }

}


How do i go about this

  • You're trying to catch an exception thrown outside your try block. That's not how exceptions work.

You can try something like this pattern if want to follow the pattern.



$arr = [1, 2, 3, 4];



foreach($arr as $a) {

    try {

        if ( $a == 2 ) {

            throw new Exception('Exception');

        }



        echo $a.' ';     

    }

    catch(Exception $e) {

        echo 'Message ';

    }



    echo PHP_EOL;

}


it will help for not breaking the loop



Result will be as:



1 Message 3 4


Hope it helps.

    Rather than throw an exception you can create a Log



    Log::error('Array value = ' . $val);
    
continue;


    This will record the issue but still allow the processing of the rest of the array



    There is more details here:

My colleague who was the previous DB admin is able to create a schema or change the permissions as there is a permission tab in the properties and he can change permissions by clicking easily. Would you please let me know how I can create schema and change permissions as well? Why his dbeaver looks different from me?

            0 $begingroup$ This is the question from a Codility test, as a task in an interview: DeepestPit - problem description A non-empty zero-indexed array A consisting of N integers is given. A pit in this array is any triplet of integers (P, Q, R) such that: ·         0 ≤ P < Q < R < N; ·         sequence [A[P], A[P+1], ..., A[Q]] is strictly decreasing, i.e. A[P] > A[P+1] > ... > A[Q]; ·         sequence A[Q], A[Q+1], ..., A[R] is strictly increasing, i.e. A[Q] < A[Q+1] < ... < A[R]. The depth of a pit (P, Q, R) is the number min {A[P] − A[Q], A[R] − A[Q]}. For example, consider array A consisting of 10 elements such that: A[0] = 0 A[1] = 1 A[2] = 3 A[3] = -2 A[4] = 0 A[5] = 1 A[6] = 0 A[7] = -3 A[8] = 2 A[9] = 3 Triplet (2, 3, 4) is
