Two identical strings, yet different lengths. Trimmed, cleansed, etc
<p>I have two strings, one is generated by PHP and stored in a database at 128 characters. The generated string is e-mailed to the user and they must input the string.</p>

<p>Now for some reason, the one from the user (with me testing), is 132 characters long through <code>var_dump</code>. When I <code>echo</code> them, they are exactly the same. Same thing for <code>var_dump</code>. Except the character count. Where are these extra 4 (invisible) characters coming from? </p>
