As far as I know, there are two ways to use PHP to output static pages. One is to use template technology, and the other is to use ob series functions. Both methods look similar, but in fact they are different.
The first way: using templates . There are currently many PHP templates, including the powerful smarty and the simple and easy-to-use smarttemplate. Each of their templates has a function to get the output content. The way we generate static pages is to use this function. The advantage of using this method is that the code is clearer and more readable.
Here I use smarty as an example to illustrate how to generate a static page
require('smarty/Smarty.class.php');
$t = new Smarty;
$t->assign("title","Hello World!");
$content = $t->fetch("templates/index.htm");
//The fetch() here is the function to get the output content. Now in the $content variable, is the content to be displayed
$fp = fopen("archives/2005/05/19/0001.html", "w");
fwrite($fp, $content);
fclose($fp);

The second method : Use the ob series of functions. The functions used here are mainly ob_start(), ob_end_flush(), ob_get_content(), where ob_start() means to open the browser buffer. After opening the buffer, all non-file header information from the PHP program will not be sent. Instead, it is stored in the internal buffer until you use ob_end_flush(). The most important function here is ob_get_contents(). The function of this function is to obtain the contents of the buffer, which is equivalent to the fetch() above. The reason Same. Code:
echo "Hello World! ";
$content = ob_get_contents();//Get all the content output by the php page
$fp = fopen("archives/2005/05/19/0001.html", "w");
fwrite($fp, $content);
fclose($fp);
?>

php把负数转为正整数的方法:1、使用abs()函数将负数转为正数,使用intval()函数对正数取整,转为正整数,语法“intval(abs($number))”;2、利用“~”位运算符将负数取反加一,语法“~$number + 1”。

实现方法:1、使用“sleep(延迟秒数)”语句,可延迟执行函数若干秒;2、使用“time_nanosleep(延迟秒数,延迟纳秒数)”语句,可延迟执行函数若干秒和纳秒;3、使用“time_sleep_until(time()+7)”语句。

php除以100保留两位小数的方法:1、利用“/”运算符进行除法运算,语法“数值 / 100”;2、使用“number_format(除法结果, 2)”或“sprintf("%.2f",除法结果)”语句进行四舍五入的处理值,并保留两位小数。

判断方法:1、使用“strtotime("年-月-日")”语句将给定的年月日转换为时间戳格式;2、用“date("z",时间戳)+1”语句计算指定时间戳是一年的第几天。date()返回的天数是从0开始计算的,因此真实天数需要在此基础上加1。

php判断有没有小数点的方法:1、使用“strpos(数字字符串,'.')”语法,如果返回小数点在字符串中第一次出现的位置,则有小数点;2、使用“strrpos(数字字符串,'.')”语句,如果返回小数点在字符串中最后一次出现的位置,则有。

方法:1、用“str_replace(" ","其他字符",$str)”语句,可将nbsp符替换为其他字符;2、用“preg_replace("/(\s|\ \;||\xc2\xa0)/","其他字符",$str)”语句。

在PHP中,可以利用implode()函数的第一个参数来设置没有分隔符,该函数的第一个参数用于规定数组元素之间放置的内容,默认是空字符串,也可将第一个参数设置为空,语法为“implode(数组)”或者“implode("",数组)”。

php字符串有下标。在PHP中,下标不仅可以应用于数组和对象,还可应用于字符串,利用字符串的下标和中括号“[]”可以访问指定索引位置的字符,并对该字符进行读写,语法“字符串名[下标值]”;字符串的下标值(索引值)只能是整数类型,起始值为0。
