Question

我有以下声明

if ( !(strstr($Description1,'word1') OR strstr($Description1,'word2') OR
       strstr($Description2,'word1') OR strstr($Description2,'word2') OR 
       strstr($Description3,'word1') OR strstr($Description3,'word2') OR 
       strstr($Description4,'word2') OR strstr($Description4,'word2') OR 
       ($_POST['fine'] == x) OR ($_POST['fine'] == y) OR ($_POST['fine'] == z))) { 

    Action1
} else { 
    Action2
}

如果任何陈述为真，它会发生什么，它会转到Action2。我想要它做的是，如果任何陈述是真的，请转到Action1

Answer 1

将“或”位保留在一组括号内 if（$ a ==“a”|| $ b ==“b”）{ 措施1} 否{Action2}

Answer 2

为什么不在开头删除!或只切换action1和action2 ??

if ((strstr($Description1,'word1') OR strstr($Description1,'word2') OR
       strstr($Description2,'word1') OR strstr($Description2,'word2') OR 
       strstr($Description3,'word1') OR strstr($Description3,'word2') OR 
       strstr($Description4,'word2') OR strstr($Description4,'word2') OR 
       ($_POST['fine'] == x) OR ($_POST['fine'] == y) OR ($_POST['fine'] == z))) { 

    Action1
} else { 
    Action2
}

或

if ( !(strstr($Description1,'word1') OR strstr($Description1,'word2') OR
       strstr($Description2,'word1') OR strstr($Description2,'word2') OR 
       strstr($Description3,'word1') OR strstr($Description3,'word2') OR 
       strstr($Description4,'word2') OR strstr($Description4,'word2') OR 
       ($_POST['fine'] == x) OR ($_POST['fine'] == y) OR ($_POST['fine'] == z))) { 

    Action2
} else { 
    Action1
}

如果具有多个条件且1个语句为真的语句不起作用
