<h1>PHP Text Validator Lib</h1>
<p>Validate input values</p>
<div class="note">
		<span>
		This library validates input values in a consistent and reliable way.<br/>
		It allows you to verify whether a given string represents a valid email address, phone number, domain, IP address, numeric value, decimal number, binary content, date, or datetime...<br/>
		<br/>
		In addition to format validation, the library supports <b>value and length constraints</b>, enabling checks for minimum and maximum values, string length, number of words, and numeric ranges.<br/>
		It also provides <b>date and datetime comparisons</b>, allowing validation of earlier or later dates, as well as date intervals.<br/>
		<br/>
		This library is ideal for input validation, form processing, API request validation, and enforcing data integrity across PHP applications.
		</span>
