Question

出于某种原因，我在设置会话变量时遇到问题，并使用if / else查看该值是否等于特定的值。这是相关代码：

function ask_name(){
     return "What is your name?\n\n";   
     $_SESSION['status'] = "name";
}

if (!isset($_SESSION["name"])||!isset($_SESSION['status'])) {
  $message = ask_name();
} 
elseif ($_SESSION["status"]==="name"){
$message = hello_name();
}
else{
    $message = respond_to_answer();
}

我知道$_SESSION["name"]肯定是设定的，但我无法让if/elseif/else转移到elseif，因为它没有$_SESSION['status']没有设置。

我在这里缺少什么？

return

$_SESSION['status'] = "name";退出当前函数并返回被调用者，这意味着您的function ask_name(){ $_SESSION['status'] = "name"; return "What is your name?\n\n"; }代码永远不会运行，切换它：

def __extractRepeats(self, repeatClass):
    process = subprocess.Popen(["./repeats1/repeats11", "-i", "-r"+repeatClass, "-n2", "-psol"],stdout=subprocess.PIPE, stdin=subprocess.PIPE, stderr=subprocess.STDOUT)
    process.stdin.write(' '.join(map(str,self.__concatenatedDAG)))
    text_file = ''
    while process.poll() is None:
        output = process.communicate()[0].rstrip()
        text_file += output
    process.wait()
    repeats=[]
    firstLine = False
    for line in text_file.splitlines():
        if firstLine == False:
            firstLine = True
            continue
        repeats.append(line.rstrip('\n'))
    return repeats

带有if / else的PHP Session变量
