The editor below will share with you an example of how to obtain ajax headers in php and its content. It has a good reference value and I hope it will be helpful to everyone. Let’s follow the editor and take a look.
1. Front-end page

2.php page
<?php $arr = get_getallheaders();//获取http头数组 //echo $arr["Token"];//输出Token var_dump($arr);//输出整个数组 function get_getallheaders() //定义方法 { foreach ($_SERVER as $name => $value) //循环_SERVER数组 { if (substr($name, 0, 5) == 'HTTP_') //前5个字符是HTTP_的进入循环 { $headers[str_replace(' ', '-', ucwords(strtolower(str_replace('_', ' ', substr($name, 5)))))] = $value; //注释 //substr($name, 5),从$name第5个字符向后截取 //str_replace('_', ' ',)下划线替换成空格 //strtolower()全部转换为小写 //ucwords()首字母转换为大写 //str_replace(' ', '-',)所有空格替换为- } } return $headers; //返回前key前5个字符是HTTP_的数组 //return $_SERVER; //返回_SERVER数组 }
3.php page returns headers
array(11) { ["Cookie"]=> string(94) "Hm_lvt_f62fa14829605f0d29c05da9c30e045a=1503649309,1503884728; _ga=GA1.1.1091059248.1504832863" ["Accept-Language"]=> string(14) "zh-CN,zh;q=0.8" ["Accept-Encoding"]=> string(17) "gzip, deflate, br" ["Referer"]=> string(62) "http://localhost/DianNaoBengKuiFangYunDuan/qrcode/headers.html" ["Token"]=>//自定义token及值 string(12) "token7758521" ["X-Requested-With"]=> string(14) "XMLHttpRequest" ["Accept"]=> string(3) "*/*" ["User-Agent"]=> string(110) "Mozilla/5.0 (Windows NT 10.0; WOW64) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/61.0.3163.100 Safari/537.36" ["Origin"]=> string(16) "http://localhost" ["Connection"]=> string(5) "close" ["Host"]=> string(9) "localhost" }

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。

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。

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。

mPDF
mPDF is a PHP library that can generate PDF files from UTF-8 encoded HTML. The original author, Ian Back, wrote mPDF to output PDF files "on the fly" from his website and handle different languages. It is slower than original scripts like HTML2FPDF and produces larger files when using Unicode fonts, but supports CSS styles etc. and has a lot of enhancements. Supports almost all languages, including RTL (Arabic and Hebrew) and CJK (Chinese, Japanese and Korean). Supports nested block-level elements (such as P, DIV),

SecLists
SecLists is the ultimate security tester's companion. It is a collection of various types of lists that are frequently used during security assessments, all in one place. SecLists helps make security testing more efficient and productive by conveniently providing all the lists a security tester might need. List types include usernames, passwords, URLs, fuzzing payloads, sensitive data patterns, web shells, and more. The tester can simply pull this repository onto a new test machine and he will have access to every type of list he needs.
