Question

我在if中使用多个条件，请参阅下面的代码;

if (strpos(serialize($row['pirority']),"P1")!==false &&
    strpos(serialize($row['product']),"WFS")!==false) 
    { $wfsp1++; }

如果我添加另一个条件则不起作用;

if (strpos(serialize($row['pirority']),"P1")!==false &&
    strpos(serialize($row['product']),"WFS")!==false) ||
    strpos(serialize($row['product']),"DayEnd")!==false) 
    { $wfsp1++; }

任何人都可以指导我，可能是什么原因？

Answer 1

您有语法错误。请尝试此

if (strpos(serialize($row['pirority']),"P1")!==false &&
    strpos(serialize($row['product']),"WFS")!==false ||   //extra parenthesis was given
    strpos(serialize($row['product']),"DayEnd")!==false) 
    { $wfsp1++; }

Answer 2

这是因为你在代码中添加了一个额外的括号。

    if (strpos(serialize($row['pirority']),"P1")!==false &&
    strpos(serialize($row['product']),"WFS")!==false ||
    strpos(serialize($row['product']),"DayEnd")!==false) 
   { $wfsp1++; }

试试这个

多个条件不适用于＆＃34;如果＆＃34;
