Visits counter without database with PHP

由 隐身守侯 提交于 2019-12-17 15:56:06
问题 I have a single webpage and i would like to track how many times it's visited without using a database. I thought about XML, updating a file every time a user visits the page: <?xml version='1.0' encoding='utf-8'?> <counter>8</counter> Then i thought it could have been a better idea to declare a PHP counter in a separate file and then update it everytime a user visits the page. counter.php <?php $counter = 0; ?> update_counter.php: <?php include "counter.php"; $counter += 1; $var = "<?php\n\t

Tracking unique visitors only?

由 末鹿安然 提交于 2019-12-17 10:54:09
问题 Currently I have a file called "hits.php" and on any page I want to track page hits I just use <?php include("hits.php"); ?> How can I track unique visitors only though? My hits are false since it can be refreshed by the same person and hits go up. Here's my source: <?php $hits = file_get_contents("./client/hits.txt"); $hits = $hits + 1; $handle = fopen("./client/hits.txt", "w"); fwrite($handle, $hits); fclose($handle); print $hits; ?> I don't really know how I could do cookie checking... is

How do I correctly use setInterval and clearInterval to switch between two different functions?

由 Deadly 提交于 2019-12-17 09:44:07
问题 For practice I am trying to display a number that increments from 0 - 9, then decrements from 9 - 0, and infinitely repeats. The code that I have so far seems to be close, but upon the second iteration the setInterval calls of my 2 respective functions countUp and countDown seem to be conflicting with each other, as the numbers displayed are not counting in the intended order... and then the browser crashes. Here is my code: <!DOCTYPE html> <html> <head> <title>Algorithm Test</title> </head>

gVim find/replace with counter

由 本秂侑毒 提交于 2019-12-17 07:26:21
问题 Is there a way to insert the value from some sort of counter variable in gVim search/replace? e.g. convert this document: <SomeElement Id="F" ... /> <SomeElement Id="F" ... /> <SomeElement Id="F" ... /> to this resulting document: <SomeElement Id="1" ... /> <SomeElement Id="2" ... /> <SomeElement Id="3" ... /> I imagine the command would look something like: :%s/^\(\s*<SomeElement Id="\)F\(".*\)$/\1<insert-counter-here>\2/g I am using a very recent Windows build, from their provided installer

Get loop counter/index using for…of syntax in JavaScript

由 不羁岁月 提交于 2019-12-17 06:59:44
问题 Caution: question still applies to for…of loops.> Don't use for…in to iterate over an Array , use it to iterate over the properties of an object. That said, this I understand that the basic for…in syntax in JavaScript looks like this: for (var obj in myArray) { // ... } But how do I get the loop counter/index ? I know I could probably do something like: var i = 0; for (var obj in myArray) { alert(i) i++ } Or even the good old: for (var i = 0; i < myArray.length; i++) { var obj = myArray[i]

Pandas groupby.size vs series.value_counts vs collections.Counter with multiple series

由 南笙酒味 提交于 2019-12-17 04:29:25
问题 There are many questions (1, 2, 3) dealing with counting values in a single series . However, there are fewer questions looking at the best way to count combinations of two or more series . Solutions are presented (1, 2), but when and why one should use each is not discussed. Below is some benchmarking for three potential methods. I have two specific questions: Why is grouper more efficient than count ? I expected count to be the more efficient, as it is implemented in C. The superior

Having trouble making a list of lists of a designated size [duplicate]

由 ☆樱花仙子☆ 提交于 2019-12-17 02:51:48
问题 This question already has answers here : List of lists changes reflected across sublists unexpectedly (13 answers) Closed 6 years ago . I am trying to make a list of lists of about 5000 lists and it keeps messing up. right now I just do this: array = [[]]*5000 for line in f2: a = line.split() grid = int(a[0]) array[grid].append(a[1]) print Counter(array[0]).most_common(10) the problem is when I make the counter it does it as if the whole array of lists was actually just one list. Is there

How to access CSS generated content with JavaScript

由 别等时光非礼了梦想. 提交于 2019-12-17 02:23:18
问题 I generate the numbering of my headers and figures with CSS's counter and content properties: img.figure:after { counter-increment: figure; content: "Fig. " counter(section) "." counter(figure); } This (appropriate browser assumed) gives a nice labelling "Fig. 1.1", "Fig. 1.2" and so on following any image. Question: How can I access this from Javascript? The question is twofold in that I'd like to access either the current value of a certain counter (at a certain DOM node) or the value of

spring boot admin + spring boot actuator + erueka 微服务监控

由 江枫思渺然 提交于 2019-12-16 21:09:59
spring boot admin + spring boot actuator + erueka 微服务监控 简单的spring boot actuator 使用 POM <dependency> <groupId>org.springframework.boot</groupId> <artifactId>spring-boot-starter-actuator</artifactId> <version>1.5.6.RELEASE</version> </dependency> application.yml 这里开启了SpringSecurity保护,一般应用上,我们使用form作为用户登录,如果需要监控程序,那么我们会需要一个与应用业务无关的账户.可以设置一个账户角色为admin,随便什么的,可以使用httpbasic验证 #开启shutdown的安全验证 management: security: enabled: true roles: USER # port: 8060 # address: 127.0.0.1 health: mail: enabled: false #允许关闭请求 endpoints: shutdown: enabled: false httpbasic验证,密码必须是经过basic64编码,这是编码,不是加密 带着请求头去请求,返回一大串数据

Python中collections模块

由 霸气de小男生 提交于 2019-12-16 01:40:55
目录 Python中collections模块 Counter defaultdict OrderedDict namedtuple deque ChainMap Python中collections模块 这个模块实现了特定目标的容器，以提供Python标准内建容器 dict、list、set、tuple 的替代选择。 Counter：字典的子类，提供了可哈希对象的计数功能 defaultdict：字典的子类，提供了一个工厂函数，为字典查询提供了默认值 OrderedDict：字典的子类，保留了他们被添加的顺序 namedtuple：创建命名元组子类的工厂函数 deque：类似列表容器，实现了在两端快速添加(append)和弹出(pop) ChainMap：类似字典的容器类，将多个映射集合到一个视图里面 Counter Counter是一个dict子类，主要是用来对你访问的对象的频率进行计数。 常用方法： elements()：返回一个迭代器，每个元素重复计算的个数，如果一个元素的计数小于1,就会被忽略。 most_common([n])：返回一个列表，提供n个访问频率最高的元素和计数 subtract([iterable-or-mapping])：从迭代对象中减去元素，输入输出可以是0或者负数 update([iterable-or-mapping])
