多個條件不能在「if」中工作

Question

我在if中使用多個條件，請參閱下面的代碼;

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

如果我添加另一個條件它不起作用;

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

任何人都可以引導我，可能是什麼原因？

Answer 1

你有語法error.Try這

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

這是因爲u必須在代碼中添加一個額外的括號。

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

試試這個
