php生成HTML文件的应用和原理笔记_PHP教程

$title = "新标题";
$content = "新内容www.bKjia.c0m";

$fp = fopen("tmp.htm", "r"); //打开文件，以只读方式。
$str = fread($fp, filesize("tmp.htm")); //读取文件内容，格式：fread(打开的文件,结束的位置);。
$str = str_replace("{title}", $title, $str); //将str变量中的路径文件内容替换掉重新赋值
$str = str_replace("{content}", $content, $str);
fclose($fp); //以上为替换模板的内容。

$id = "hello";
$path = $id . '.htm';
$handle = fopen($path, "w"); //写入方式打开新闻路径
fwrite($handle, $str); //把刚才替换的内容写进生成的HTML文件
fclose($handle);
echo "生成成功";
