    # strip_html

    (PHP 5 >= 5.4)
    `strip_html` — Strip HTML and PHP tags from a string.

    ## Description

    ```php
    string strip_html( string $str )
    ```

    This function tries to return a string with all NULL bytes, HTML and PHP tags stripped from a given `str`. Unlike [`strip_tags()`](https://php.net/strip-tags), this function is mindful of line-breaks and metadata elements (e.g., `<style>`).

    This function is useful for converting a HTML-rich string into a plain-text string for emails.

    ## Parameters

    - `str` — The input string.

    ## Return Values

    Returns the stripped string.

    ## Installation
