Isn’t there a file_put_content() function?
You need to use the ob_start() series of methods,
Using curl file_get_contentS and other simulated requests will be very inefficient, and various frameworks are implemented using ob
It’s difficult to type on the mobile phone, I don’t know for sure
You can take a look at the Output Control function in php
Why not use wget to directly grab the mirror and download it as a tgz package
`ob_start();
//Template processing
//echo template content
$content = ob_get_contents();
ob_end_clean();
file_put_contents('./demo.html', $content);`
It can also be implemented using smart templates, as shown below:
<code><?php require('smarty/Smarty.class.php'); $t = new Smarty; $t->assign("title","Hello World!"); $content = $t->fetch("templates/index.htm"); //这里的 fetch() 就是获取输出内容的函数,现在$content变量里面,就是要显示的内容了 $fp = fopen("archives/2005/05/19/0001.html", "w"); fwrite($fp, $content); fclose($fp); ?></code>
It is also very easy to use.
<code><?php /* 在这里数据库增删改查之前对缓存进行过期判断和应用 */ $app['data'] = db_crud(); $view = render('index.php'); function render($template) { global $app; ob_end_clean(); ob_start(); require APP_ROOT.'/view/'.$template; //模板里会用到数据$app['data'] $html = ob_get_contents(); ob_end_clean(); ob_start(); /* 在这里把 ob_get_contents 拿到的字符串 file_put_contents 写入文件系统 */ return $html; }</code></code>

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。

在php中,可以使用substr()函数来读取字符串后几个字符,只需要将该函数的第二个参数设置为负值,第三个参数省略即可;语法为“substr(字符串,-n)”,表示读取从字符串结尾处向前数第n个字符开始,直到字符串结尾的全部字符。

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。

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。
