php生成html文件方法总结
本文这里汇总了一些自己使用的和网上搜集来的php生成html静态文件的方法，非常的使用，也分析了他们的优缺点，是篇非常不错的文章，这里推荐给大家。
我经常会在网上看到有人问怎么将整个动态的网站静态化，其实实现的方法很简单。
代码如下:
<?php //在你的开始处加入 ob_start(); ob_start(); //以下是你的代码 //在结尾加入 ob_end_clean(),并把本页输出到一个变量中 $temp = ob_get_contents(); ob_end_clean(); //写入文件 $fp = fopen (‘文件名','w'); fwrite($fp,$temp) or die(‘写文件错误'); ?>
这只是最基本的方法，还不是很实用，因为网站是要更新的，要定期重新生成HTML
下面是我用的方法：
代码如下:
if(file_exists(“xxx.html”))
{
$time = time();
//文件修改时间和现在时间相差半小时一下的话，直接导向html文件，否则重新生成html
if($time - filemtime(“xxx.html”) < 30*60)
{
header(“Location:xxx.html”);
}
}
//在你的开始处加入 ob_start();
ob_start();
//页面的详细内容
//在结尾加入 ob_end_clean(),并把本页输出到一个变量中
$temp = ob_get_contents();
ob_end_clean();
//写入文件
$fp = fopen(‘xxx.html','w');
fwrite($fp,$temp) or die(‘写文件错误');
//重新导向
header(“Location:xxx.html”);上面用的缓存文件在大量生成时会出现负载过重，下面我们介绍一种更为高效的方法
以下是输入内容的提交页面：
文件名:aa.html
代码如下:
<html> <head> <title>提交页面</title> <meta http-equiv="Content-Type" content="text/html; charset=gb2312"> </head> <body> <form method="post" action="bb.php"> 标题：<input type="text" name="htmltitle"><br> 内容：<textarea rows="8" cols="45" name="htmlbody"></textarea><br> <input type="submit" name="submit" value="添加新闻"> </form> </body> </html>
以下是代码片段：
文件名：bb.php
代码如下:
<?php
//定义日期函数
function getdatetime()
{
$datetime=getdate();
$strReturn=$datetime["year"]."-";
$strReturn=$strReturn.$datetime["mon"]."-";
$strReturn=$strReturn.$datetime["mday"];
return $strReturn;
}
//定义时间函数（文件名)
function gettime()
{
$times=getdate();
$strtime=$times["year"];
$strtime=$strtime.$times["mon"];
$strtime=$strtime.$times["mday"];
$strtime=$strtime.$times["minutes"];
$strtime=$strtime.$times["seconds"];
return $strtime;
}
?><?php
//判断提交值是否为空
$submit=$_POST["submit"];
//定义文件头部信息
$htmltitle=$_POST["htmltitle"];
//定义文件内容
$htmlbody=$_POST["htmlbody"];
if ($submit) {
//定义html文件标签
$html1=$html1."<html>";
$html1=$html1."<head>";
$html1=$html1."<title>";
$html1=$html1.$htmltitle;
$html1=$html1."</title>";
$html1=$html1."<meta http-equiv='Content-Type' content='text/html; charset=gb2312'>";
$html1=$html1."</head>";
$html1=$html1."<body>";
$html1=$html1."<table border='1' width='740' cellpadding='2' cellspacing='0' bordercolordark='#f7f7f7' bordercolorlight='#cccccc'><tr><td align='center' bgcolor='#f7f7f7' height='30'><font size='3'><b>";
$html1=$html1.$htmltitle;
$html1=$html1."</b></font></td></tr>";
$html1=$html1."<tr><td><font size='2'>";
$html1=$html1.$htmlbody;
$html1=$html1."</font></td></tr></table>";
$html1=$html1."</body>";
$html1=$html1."</html>";
//判断今天的文件夹是否存在
if (!is_dir(getdatetime())) {
//如果不存在就建立
mkdir(getdatetime(),0777);
}
//写成html文件
$filedir=getdatetime();
$filename=gettime();
$filename=$filename.".html";
$fp=fopen("$filedir/$filename","w");
fwrite($fp,$html1);
fclose
($fp);
echo "<script>alert('文件写入成功');location.href='111.php';</script>";
}
?>如果提示文件写入成功，那你就成功了，然后回到你的相应目录里看看有没有生成静态的html文件！
smarty模板生成方法
代码如下:
<?php
require_once("./config/config.php");
ob_start();
$id=$_GET[id];
$sql="select * from table_name where id='$id'";
$result=
mysql_query
($sql);
$rs=mysql_fetch_object($result);
$smarty->assign("showtitle",$rs->title);
$smarty->assign("showcontent",$rs->content);
$smarty->
display
("content.html");
$this_my_f= ob_get_contents();
ob_end_clean();
$filename = "$id.html";
tohtmlfile_cjjer($filename,$this_my_f);
// 文件生成函数
function tohtmlfile_cjjer($file_cjjer_name,$file_cjjer_content){
if (is_file ($file_cjjer_name)){
@unlink ($file_cjjer_name); //存在，就删除
}
$cjjer_handle = fopen ($file_cjjer_name,"w"); //创建文件
if (!is_writable ($file_cjjer_name)){ //判断写权限
return false;
}
if (!fwrite ($cjjer_handle,$file_cjjer_content)){
return false;
}
fclose ($cjjer_handle); //关闭指针
return $file_cjjer_name; //返回文件名
}
?>
smarty中有一个获取模板页内容方法fetch(), 它的声明原形是这样的:
代码如下:
<?php $smarty = new Smarty(); //其它模板替换语法... //下面这句取得页面中所有内容, 注意最后一个参数为false $content = $smarty->fetch('模板名称.tpl', null, null, false); //下面将内容写入至一个静态文件 $fp = fopen('news.html', 'w'); fwrite($fp, $content); fclose($fp); //OK, 到这里这个news.html静态页就生成了, 你可以处理你下一步的工作了 ?>
好了结合上面的方法我们生成文件几乎原理都一样，先把数据读取出来然后给我们定义好的模板，最后利用fopen函数生成一个.html的文件
以上几种php生成html静态文件的方法原理上都大同小异，只是在方法上略有不同，都有优缺点，大家根据自己的项目需求，自由选择吧

Explain JSON Web Tokens (JWT) and their use case in PHP APIs.
Apr 05, 2025 am 12:04 AM
JWT is an open standard based on JSON, used to securely transmit information between parties, mainly for identity authentication and information exchange. 1. JWT consists of three parts: Header, Payload and Signature. 2. The working principle of JWT includes three steps: generating JWT, verifying JWT and parsing Payload. 3. When using JWT for authentication in PHP, JWT can be generated and verified, and user role and permission information can be included in advanced usage. 4. Common errors include signature verification failure, token expiration, and payload oversized. Debugging skills include using debugging tools and logging. 5. Performance optimization and best practices include using appropriate signature algorithms, setting validity periods reasonably,
