所以我試圖做一個網站,並且我使用一個PHP文件作爲索引(index.php),並且非常像控制頁面整個網站。防止str_replace評論字符串中的php代碼
由於它收到所有的請求並返回使用str_replace
的頁面,它的所有工作都應該如此(因爲它使Web模板按照它應該的工作),但問題是我無法在PHP代碼中使用文件是模板的一部分,只在index.php中。
所以我的問題是,有沒有辦法阻止str_replace
將php代碼轉換爲註釋?
的index.php:
<?php
//dirs
$pagesDir = "pages/";
$templatesDir = "templates/";
$errorsDir = "errors/";
if (isset($_REQUEST['page'])) {
if ($_REQUEST['page'] != "")
if (file_exists($pagesDir . $_REQUEST['page'] . ".html"))
$page_content = file_get_contents($pagesDir . $_REQUEST['page'] . ".html");
else
if (file_exists($_REQUEST['page'] . ".html"))
$page_content = file_get_contents($_REQUEST['pages'] . ".html");
else
echo "<h1>Page:" . $_REQUEST['page'] . " does not exist! Please check the url and try again!</h1>";
} else {
$page_content = file_get_contents($pagesDir . "home.html");
}
//PLACEHOLDER REPLACEMENT
$page_content = str_replace("!!HEAD!!", file_get_contents($templatesDir . "head.html"), $page_content);
$page_content = str_replace("!!BODY!!", file_get_contents($templatesDir . "body.html"), $page_content);
$page_content = str_replace("!!FOOT!!", file_get_contents($templatesDir . "eofScripts.html"), $page_content);
//RETURN THE CONTENT OF THE PAGE
echo $page_content;
新調度後的變化(這一個工程):
<?php
$templatesDir = "templates/";
$pagesDir = "pages/";
$loggedPagesDir = "templates/logged";
$pageExists = false;
$pageContent = null;
require_once('scripts/php/db_conn.php');
if (isset($_REQUEST['page'])) {
$page = $_REQUEST['page'] . ".php";
}
if (isset($_SESSION['redirect_reason'])) {
$dialogs->alertDialog("warningDialog", $_SESSION['redirect_reason']);
unset($_SESSION['redirect_reason']);
}
if (isset($_SESSION['user_action'])) {
$dialogs->alertDialog("infoDialog", $_SESSION['user_action']);
unset($_SESSION['user_action']);
}
if ($user->is_logged()) { //Only runs beyond this point if user is logged, if not, it will run the other one.
if (isset($_POST['logout_btn'])) {
$user->logout();
$user->redirect("pageDispatcher.php");
}
if (isset($page)) {
if ($page != "") {
if (file_exists($pagesDir . $page)) {
$pageExists = true;
$pageContent = ($pagesDir . $page);
} else {
echo "<h1>Page: " . $page . "does not exist! Please check the url and try again</h1>";
}
} else {
$pageExists = true;
$pageContent = ($pagesDir . "loggedhome.php");
}
} else {
$pageExists = true;
$pageContent = ($pagesDir . "loggedhome.php");
}
} else { //Only runs beyond this point if user isn't logged.
if (isset($_POST['login_btn'])) {
if ($user->login($_POST['email'], $_POST['password']) == false) {
$dialogs->loginFailed();
} else {
$_SESSION['user_action'] = "Welcome back " . $_SESSION['user_name'];
$user->redirect("pageDispatcher.php");
}
}
if (isset($page)) {
if ($page != "") {
if (file_exists($pagesDir . $page)) {
$pageExists = true;
$pageContent = ($pagesDir . $page);
} else {
echo "<h1>Page: " . $page . " does not exist! Please check the url and try again!</h1>";
}
} else {
$pageExists = true;
$pageContent = ($pagesDir . "home.php");
}
} else {
$pageExists = true;
$pageContent = ($pagesDir . "home.php");
}
}
?>
<html>
<?php include($templatesDir . "head.html"); ?>
<body>
<?php
if ($user->is_logged()) {
include($templatesDir . "loggedBody.html");
} else {
include($templatesDir . "body.html");
}
include($pageContent);
?>
</body>
</html>
注意:除非是出於學習的目的,它的壞,不要使用此方法就可以了,結果很難維護,並且可能最終會變得很慢,因爲我有很多服務器端方法可以做客戶端。

我認爲OP正試圖將他的模板作爲字符串進行回顯,並且他在結果頁面中看到了php標籤(和我的猜測)。 – Aioros
