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.<br /> 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 <a href="function.variant-add.html" class="function">variant_add()</a> in PHP corresponds to <i>VarAdd() </i> in the MSDN documentation.<br /></p></blockquote> </div> <div class="refsect1 returnvalues"> <h3 class="title">Return Values</h3> <p class="para"> If <i><tt class="parameter">variant</tt></i> is negative, then the first negative integer greater than or equal to the variant is returned, otherwise returns the integer portion of the value of <i><tt class="parameter">variant</tt></i>. </p> </div> <div class="refsect1 notes"> <h3 class="title">Notes</h3> <div class="warning"><b class="warning">Warning</b> <p class="simpara"> This documentation is based on the MSDN documentation; it appears that this function is either the same as <a href="function.variant-int.html" class="function">variant_int()</a>, or that there is an error in the MSDN documentation. </p> </div> </div> <div class="refsect1 seealso"> <h3 class="title">See Also</h3> <p class="para"> <ul class="simplelist"> <li class="member"><a href="function.variant-int.html" class="function" rel="rdfs-seeAlso">variant_int()</a></li> <li class="member"><a href="function.variant-round.html" class="function" rel="rdfs-seeAlso">variant_round()</a></li> <li class="member"><a href="function.floor.html" class="function" rel="rdfs-seeAlso">floor()</a></li> <li class="member"><a href="function.ceil.html" class="function" rel="rdfs-seeAlso">ceil()</a></li> <li class="member"><a href="function.round.html" class="function" rel="rdfs-seeAlso">round()</a></li> </ul> </p> </div></div><hr /><div style="text-align: center;"> <div class="prev" style="text-align: left; float: left;"><a href="function.variant-eqv.html">variant_eqv</a></div> <div class="next" style="text-align: right; float: right;"><a href="function.variant-get-type.html">variant_get_type</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>⌨️ 快捷键说明
