PHP从函数中获取数组值

Question

I have the following function:

function telephoneNums($telephoneNum) {
    $telephoneNum = trim($telephoneNum);
    $telephoneNum = preg_replace("/[^0-9]/", '', $telephoneNum);

    if($telephoneNum !=8){
        $errorMsg[] = 'The contact number must be exactly 8 charators long';
    }


    return $telephoneNum;
    return array_values($errorMsg[]);
}

I am managing to return $telephoneNum but I am not managing to return $errorMsg[] - I am getting the following error PHP Fatal error: Cannot use [] for reading

I also tried return $errorMsg[]; but I still get the same errors.

How can I return $errorMsg[]

Answer 1

Just try like

return array_values($errorMsg);

And you also having return statement before this line.Try to return at once.In your case after the first return statement it won't return the second value.

Also just initialize the $errorMsg like

$errorMsg = array();

If your IF condition not satisfies then at least it should be initialized with empty value or as an array.
