Filters string for valid email characters.

Parameters:

path

Description:

Filters string for valid path syntax, with optional trailing slash.

This method removes any whitespace, spaces, and leading slashes. It will also convert reverse and multiple slashes to one single forward slash.

• $trailing = true (bool): Require trailing slash

Returns:

• (string)

Example:

$path = '/some/ bad//path';

escape

Description:

Escape strings and arrays. Other data types return their original value.

NOTE: Use caution when escaping entire arrays, as strings should typically only be escaped when outputting to HTML.

See: https://www.php.net/manual/en/mbstring.supported-encodings.php

Parameters:

• $value (mixed)
• $encoding = 'UTF-8' (string)

Returns:

use Bayfront\Sanitize\Sanitize;

$html = '<a href="#">Hyperlink</a>';
