Code Examples

// minimum password check php - JavaScript
const regex = /^(?=.*[a-z])(?=.*[A-Z])(?=.*\d)(?=.*[@$!%*?&])[A-Za-z\d@$!%*?&]{8,}$/;

function validate(input) {
  if (!input || typeof input !== 'string') return false;
  return regex.test(input.trim());
}

// Usage examples
console.log(validate('MyPassword123!')); // true
console.log(validate('weak')); // false

# minimum password check php - Python
import re

pattern = r"^(?=.*[a-z])(?=.*[A-Z])(?=.*\d)(?=.*[@$!%*?&])[A-Za-z\d@$!%*?&]{8,}$"
regex = re.compile(pattern)

def validate(input_str):
    if not input_str or not isinstance(input_str, str):
        return False
    return bool(regex.match(input_str.strip()))

# Usage examples
print(validate('MyPassword123!'))  # True
print(validate('weak'))  # False

<?php
// minimum password check php - PHP
function validate($input) {
    if (!is_string($input) || empty(trim($input))) {
        return false;
    }
    
    $pattern = '/^(?=.*[a-z])(?=.*[A-Z])(?=.*\d)(?=.*[@$!%*?&])[A-Za-z\d@$!%*?&]{8,}$/';
    return preg_match($pattern, trim($input)) === 1;
}

// Usage examples
var_dump(validate('MyPassword123!')); // bool(true)
var_dump(validate('weak')); // bool(false)
?>
