核心代码如下:
复制代码 代码如下:
$now=time();
$oc = array(
'team_type' => 'normal',
"begin_time "end_time > '{$now}'",
);
$p="p2";
$pp1="";
$pp2="";
$now = time();
switch ($p)
{
case "p1":
$pp1="team_price $pp2="";
break;
case "p2":
$pp1="team_price > 10";
$pp2="team_price break;
case "p3":
$pp1="team_price > 50";
$pp2="team_price break;
case "p4":
$pp1="team_price > 100";
$pp2="team_price break;
case "p5":
$pp1="team_price > 200";
$pp2="";
break;
default:
$pp1="";
$pp2="";
}
if(!empty($pp1)){
array_push($oc,$pp1);
}
if(!empty($pp2)){
array_push($oc,$pp2);
}
print_r($oc);
?>
因为是多条件查询所以需要先判断是否为空,然后再添加到数组里面。

php求2个数组相同元素的方法:1、创建一个php示例文件;2、定义两个有相同元素的数组;3、使用“array_intersect($array1,$array2)”或“array_intersect_assoc()”方法获取两个数组相同元素即可。

C语言数组初始化的三种方式:1、在定义时直接赋值,语法“数据类型 arrayName[index] = {值};”;2、利用for循环初始化,语法“for (int i=0;i<3;i++) {arr[i] = i;}”;3、使用memset()函数初始化,语法“memset(arr, 0, sizeof(int) * 3)”。

Part1聊聊Python序列类型的本质在本博客中,我们来聊聊探讨Python的各种“序列”类,内置的三大常用数据结构——列表类(list)、元组类(tuple)和字符串类(str)的本质。不知道你发现没有,这些类都有一个很明显的共性,都可以用来保存多个数据元素,最主要的功能是:每个类都支持下标(索引)访问该序列的元素,比如使用语法Seq[i]。其实上面每个类都是使用数组这种简单的数据结构表示。但是熟悉Python的读者可能知道这3种数据结构又有一些不同:比如元组和字符串是不能修改的,列表可以

c++初始化数组的方法:1、先定义数组再给数组赋值,语法“数据类型 数组名[length];数组名[下标]=值;”;2、定义数组时初始化数组,语法“数据类型 数组名[length]=[值列表]”。

增加元素的方法:1、使用unshift()函数在数组开头插入元素;2、使用push()函数在数组末尾插入元素;3、使用concat()函数在数组末尾插入元素;4、使用splice()函数根据数组下标,在任意位置添加元素。

php判断数组里面是否存在某元素的方法:1、通过“in_array”函数在数组中搜索给定的值;2、使用“array_key_exists()”函数判断某个数组中是否存在指定的key;3、使用“array_search()”在数组中查找一个键值。

元组是固定长度不可变的顺序容器(元素序列),go语言中没有元组类型,数组就相当于元组。在go语言中,数组是一个由固定长度的特定类型元素组成的序列,一个数组可以由零个或多个元素组成;数组的声明语法为“var 数组变量名 [元素数量]Type”。

php去除第一个数组元素的方法:1、新建一个php文件,并创建一个数组;2、使用“array_shift”方法删除数组首个元素;3、通过“print_”r输出数组即可。

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.

Mantis is an easy-to-deploy web-based defect tracking tool designed to aid in product defect tracking. It requires PHP, MySQL and a web server. Check out our demo and hosting services.

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),
