Please suggest a code which returns length of longest string passed as its arguments in php
<p>There is a function GetLongestString, whose arguments are character strings. It should return an integer representing the length of the longest string passed as its argument; for example:</p>

<pre><code>GetLongestString("a", "aaa", "aa");             // should return 3,
GetLongestString("a", "bcd", "efgh", "ij", ""); // should return 4.
</code></pre>
