📄 PHPValidator
==============

[](#-phpvalidator)

A flexible PHP validation class for validating strings, numbers, and files. It supports both static chaining and method chaining for clear and readable validation rules.

[](#-custom-validation)

```
->custom(callable $callback, string $errorMessage)
```

Run any custom logic. If it fails, the provided error message is returned.

Example:

```
->custom(fn($v) => strlen($v) % 2 === 0, 'Length must be even.')
```

### 🚦 Final Step

[](#-final-step)

`->run()`Executes all validation rules and returns an array of error messages.

#### 🧪 Examples

[](#-examples)

##### Validate String

[](#validate-string)

```
$errors = Validate::string('Hello123!')
    ->min_length(5)
    ->max_length(10)
    ->uppercase()
    ->lowercase()
    ->has_number()
    ->special_character()
    ->run();
```

##### Validate Number

[](#validate-number)

```
$errors = Validate::number(5.5)
    ->min(0)
    ->max(10)
    ->float()
    ->run();
```

##### Validate File Upload

[](#validate-file-upload)

```
$errors = Validate::file('image')
    ->min_size(100) // 100KB
    ->max_size(2048) // 2MB
    ->allowed_extension(['jpg', 'png'])
    ->allowed_mime(['image/jpeg', 'image/png'])
    ->run();
```

#### 🧼 Notes

[](#-notes)

`run()` always returns an array. If valid, it will be an empty array.

File size is automatically handled in kilobytes.

You can extend this class easily with more rules or by subclassing.

Let me know if you'd like a version of this in a .md file or integrated into a documentation tool.
