Validations

The GenericDatabase\Helpers\Validations class provides several static methods for performing common validation tasks. These methods include checking if a value is numeric, checking "Booleanic" conditions, generating random strings, and detecting if a query is a SELECT statement.

Example Usage:

// Check if a value is numeric
$value = '123';
$isNumber = Validations::isNumber($value);
echo $isNumber ? 'Numeric' : 'Not numeric';

Output: Numeric

// Check "Booleanic" conditions
$value = 'true';
$isBoolean = Validations::isBoolean($value);
echo $isBoolean ? 'True' : 'False';

Output: True

// Generate a random string
$length = 10;
$randomString = Validations::randomString($length);
echo $randomString;

Output: Random string of length 10

Main functionalities:

• The isNumber method checks if a value is numeric by using the is_numeric function.
• The isBoolean method checks "Booleanic" conditions by using the filter_var function with the FILTER_VALIDATE_BOOLEAN flag.
• The randomString method generates a random string of a specified length by selecting random characters from an array of letters.
• The isSelect method detects if a query is a SELECT statement by checking if the query starts with the word "SELECT" (case-insensitive).

Methods:

• isNumber(string $value): bool: Checks if a value is numeric.
• isBoolean(mixed $value): mixed: Checks "Booleanic" conditions.
• randomString(int $length): string: Generates a random string of a specified length.
