为什么要赢得这项工作？如果$ a Boolean为true，它应该只显示html。 我是否正确地使用PHP有条不紊地显示HTML？ 我真的不知道为什么它不会工作。我真的很感激能给予我任何帮助。 ：）

答案 0 :(得分：7)
您需要在输出原始HTML时关闭PHP，以便在此处更改
import UIKit
import GoogleMobileAds
class ViewController: UIViewController, GADInterstitialDelegate {
var admobInterstitial : GADInterstitial?
var timer : NSTimer?
override func viewDidLoad() {
super.viewDidLoad()
admobInterstitial = createAndLoadInterstitial()
timer = NSTimer.scheduledTimerWithTimeInterval(5.0, target:self, selector: Selector("presentInterstitial"), userInfo: nil, repeats: false)
}
func createAndLoadInterstitial()->GADInterstitial {
var interstitial = GADInterstitial(adUnitID: "yourAdMobADUnitID")
interstitial.delegate = self
interstitial.loadRequest(GADRequest())
return interstitial
}
func presentInterstitial() {
if let isReady = admobInterstitial?.isReady {
admobInterstitial?.presentFromRootViewController(self)
}
}
func interstitial(ad: GADInterstitial!, didFailToReceiveAdWithError error: GADRequestError!) {
println("interstitialDidFailToReceiveAdWithError:\(error.localizedDescription)")
admobInterstitial = createAndLoadInterstitial()
}
在最底层改变
<!DOCTYPE html>
<html>
<?php
$a = False;
if($a == True){
?> <-- new line
<head>
答案 1 :(得分：1)
您的问题是您正在尝试将HTML解析为PHP。您必须关闭PHP标记，或者回显它。关闭PHP标签可能更好，因为：
if($a == True){
?>
<head>
<!--- More HTML here --->
并在if语句的结束括号之前打开它：
<!--- HTML coming in here... --->
</body>
<?php } ?>
