我试图弄清楚这一点，但代码在我的自定义函数页面上的函数内部不起作用。即使它确实运行了返回到我的报告中的值以添加到我的 $html 以供以后回显。想法？？？

谢谢！！

所以我为那些不知道该怎么做的人想出来了。

该函数正在工作，但只是我没有计算返回值。基本上我需要设置

return $html;

这将发回我想要返回的 html，在另一个页面上，我想设置一个值以等于返回值或像这样回显返回值。

$html = sql_prepare(...insert values sent here,$html);

或者

 echo sql_prepare(...insert values sent here,$html);

这完成了工作。感谢您的回复
