Php（使用数组的表）

Question

How would I make a table that takes a PHP array. The array is decided by a html input. The table has the actual values in the first column, length in the second column, and if it starts with 3 letters, 3 numbers or neither in the third column.

echo '<table>';
    foreach ($array as $key => $value) {
        echo '<tr><td>';
        echo htmlspecialchars($array);
        echo '</td><td>';
        echo strlen($array);
        echo '</td><td>';

            //to work on
            $trim = substr($array, 0, 3);
                if(is_numeric($trim)){
                    echo 'numeric';
                }elseif(is_string($trim)){
                    echo 'string';
                }else{
                    echo 'else ?';
                }

        echo '</td></tr>';
        }
    echo '</table>';

Answer 1

PHP will interpret POST values with brackets in their name as arrays.

<form method="POST">
    <input type="text" name="values[]" >
    <input type="text" name="values[]" >
    <input type="text" name="values[]" >
    <button type="submit">Go</button>
</form>

Now... The solution presented here is only to get you started. The third column can be a bit tricky because a value of 'ab123c' will pass as string.

I will let you work the kinks the way you want them to be handled.

if(is_array($_POST['values'])){
    echo '<table>';
        foreach ($_POST['values'] as $key => $value) {
            echo '<tr><td>';
            echo htmlspecialchars($value);
            echo '</td><td>';
            echo strlen($value);
            echo '</td><td>';

                //to work on
                $trim = substr($value, 0, 3);
                    if(is_numeric($trim)){
                        echo 'numeric';
                    }elseif(is_string($trim)){
                        echo 'string';
                    }else{
                        echo 'else ?';
                    }

            echo '</td></tr>';
            }
        echo '</table>';
}

PS: Never trust user input ;)

I know the code is not squeaky clean, the goal was for it to be easy to understand.
