if 语句的单独子句？
有没有办法在 if() 语句中包含多个子句？
例如：
if( ($username=='textUser' && $role=='admin') || ($admin=='yes'))
{
// If the username AND role are set to admin OR if the admin is set to 'yes'
}
else
{
// Neither clauses of the if statement are true
}
也许这实际上是正确的代码，我没有尝试过 - 但如果没有，有人能告诉我怎么做吗？ :)
Is there any way to have multiple clauses in an if() statement?
For instance:
if( ($username=='textUser' && $role=='admin') || ($admin=='yes'))
{
// If the username AND role are set to admin OR if the admin is set to 'yes'
}
else
{
// Neither clauses of the if statement are true
}
Perhaps this is actually the correct code, i have no tried it - but if not, could anyone tell me how? :)

这实际上是正确的代码。除了
||，您还可以使用或（尽管它们在 运算符优先级，与当前的情况无关，但值得注意，欢呼@Timothy。）我倾向于将每个条件放入
$a == b放入括号中：($a == b)以避免复杂的if语句中出现有趣的情况。That is actually the correct code. Instead of
||, you can also useor(although they differ slightly in operator precedence, not relevant in the case at hand but worth noting, cheers @Timothy.)I tend to put every condition
$a == binto brackets:($a == b)to avoid funny situations in complexifstatements.
