PHP native types will be converted to variants using the same rules as found in the constructor for the <a href="class.variant.html" class="xref">VARIANT</a> class. COM and DOTNET objects will have the value of their default property taken and used as the variant value. </p> <p class="para"> The variant arithmetic functions are wrappers around the similarly named functions in the COM library; for more information on these functions, consult the MSDN library. The PHP functions are named slightly differently; for example <span class="function"><a href="function.variant-add.html" class="function">variant_add()</a></span> in PHP corresponds to <em>VarAdd() </em> in the MSDN documentation. </p> </p></blockquote> </div> <div class="refsect1 returnvalues" id="refsect1-function.variant-eqv-returnvalues"> <h3 class="title">Return Values</h3> <p class="para"> If each bit in <em><code class="parameter">left</code></em> is equal to the corresponding bit in <em><code class="parameter">right</code></em> then <strong><code>TRUE</code></strong> is returned, otherwise <strong><code>FALSE</code></strong> is returned. </p> </div> </div><hr /><div class="manualnavbar" style="text-align: center;"> <div class="prev" style="text-align: left; float: left;"><a href="function.variant-div.html">variant_div</a></div> <div class="next" style="text-align: right; float: right;"><a href="function.variant-fix.html">variant_fix</a></div> <div class="up"><a href="ref.com.html">COM Functions</a></div> <div class="home"><a href="index.html">PHP Manual</a></div> </div></body></html>
