var with regexp validates more than expected

I'm trying to work with PHP's filter_var function to validate some inputs from an uploaded CSV. A couple of the values I'm working with don't fall into the built-in validation filters, so I turned to FILTER_VALIDATE_REGEXP. I'm getting different results in PHP than I am from http://regex101.com/, where I was playing around to make sure I get my patterns right. My issue i

var与regexp验证超出预期

我正在尝试使用PHP的filter_var函数来验证上传的CSV中的一些输入。我正在使用的几个值不属于内置的验证过滤器，所以我转向了FILTER_VALIDATE_REGEXP。我在PHP中得到了不同于http://regex101.com/的结果，我在那里玩耍以确保我的模式正确无误。我的问题是，一些非常基本的模式在PHP中并不适合我，而filter_var允许通过的字符串看起来不符合我的模式。一些例子： php > $regex = array("options" => array("rege

var in php 5.3.8

I am developing a user registration form and want to validate a user's email address. However,all the php docs I have read suggest the use of filter_var. My script validates a valid email as invalid. Please post a working script or perhaps guide me through my script. Hers is my script : <?php if(isset($_POST['email'])== true && empty($_POST['email'])false) {

var在PHP 5.3.8中

我正在开发用户注册表单并希望验证用户的电子邮件地址。但是，我读过的所有php文档都提示使用filter_var。我的脚本验证有效的电子邮件是无效的。请发布一个工作脚本，或者引导我通过我的脚本。她的是我的剧本： <?php if(isset($_POST['email'])== true && empty($_POST['email'])false) { $email = $_POST['email']; } if(filter_var($email,FILTER_VALIDATE_EMAIL))

var W/ FILTER

I've searched this site for similar answers and I still can't make up my mind. Also I'm new to this site. I'm in the process of developing a PHP script to allow users to register. After they register they are sent a email with a token to validate that they have access to that email saying it is valid and it will mark them as 'valid users' otherwise it will delete that

var W / FILTER

我在这个网站上搜索了类似的答案，但我仍然无法下定决心。另外我是这个网站的新手。我正在开发一个PHP脚本以允许用户注册。在他们注册后，他们会发送一封带有令牌的电子邮件来验证他们是否有权访问该电子邮件，说明该电子邮件有效，并将其标记为“有效用户”，否则它会在设定的时间后删除该条目。我想知道的是，如果我制作的自定义REGEX（大部分工作相当好，只需要不时调整），或者filter_var与FILTER_VALIDATE_EMAIL比我

Is using PHP's explode() for HTML scraping considered a bad practice?

I have been coding for a while now but just can't seem to get my head around regular expressions. This brings me to my question which is the following: is it bad practice to use PHP's explode for breaking up a string of html code to select bits of text? I need to scrape a page for various bits of information and due to my horrific regex knowledge (In a full software engineering degree

使用PHP的explode（）进行HTML抓取被认为是一种不好的做法？

我一直在编写代码，但似乎无法绕过正则表达式。这使我想到了以下问题：使用PHP的爆炸破解一串html代码来选择文本的位是不好的做法？我需要为各种信息刮掉一页，并由于我的可怕的正则表达式知识（在一个完整的软件工程学位，我不得不写一个......）我决定使用explode（）。我在下面提供了我的代码，所以比我更有经验的人可以告诉我是否使用正则表达式是必要的！ public function split_between($start, $end, $blob) {

php

Zend_Validate_EmailAddress和filter_var(..., FILTER_VALIDATE_EMAIL) ，这在验证电子邮件地址时更好，为什么？ Both can be used to validate an email address, but Zend_Validate_EmailAddress is more powerful. While filter_var is a simple yes or no validator, there are many options which can change how strict Zend_Validate_EmailAddress is. You can choose which parts to validate, rules for validating

Zend_Validate_EmailAddress和filter_var(..., FILTER_VALIDATE_EMAIL) ，这在验证电子邮件地址时更好，为什么？两者都可用于验证电子邮件地址，但Zend_Validate_EmailAddress功能更强大。虽然filter_var是一个简单的yes或no验证器，但有很多选项可以改变Zend_Validate_EmailAddress的严格程度。您可以选择验证哪些部分，验证这些部分的规则，甚至是验证MX记录。最后，可以将Zend_Validate_EmailAddress与Zend_Filter_

var($email, FILTER

I was just setting up the validation for a form in which I decided to try using the filter_var function to check the validity of my email address. I can not find out what filter_var actually allows anywhere though (since the documentation is very simple), and I found out that it is allowing an email address like test@test. Doesn't there have to be a .com, .net etc... in the domain? The be

var（$ email，FILTER

我只是设置了表单的验证，我决定尝试使用filter_var函数来检查我的电子邮件地址的有效性。我无法找到filter_var实际上允许的任何地方（因为文档非常简单），并且我发现它允许像test @ test这样的电子邮件地址。在域中不必有.com，.net等...吗？这种行为在四月份左右发生了变化。请参阅错误＃49576和修订版297350。该电子邮件确实无效，或者至少这是PHP开发人员所理解的。信息来源载有此通知： /* * The regex bel

PHP function to generate v4 UUID

So I've been doing some digging around and I've been trying to piece together a function that generates a valid v4 UUID in PHP. This is the closest I've been able to come. My knowledge in hex, decimal, binary, PHP's bitwise operators and the like is nearly non existant. This function generates a valid v4 UUID up until one area. A v4 UUID should be in the form of: xxxxxxxx-xx

PHP函数生成v4 UUID

所以我一直在做一些挖掘工作，我一直在拼凑一个可以在PHP中生成有效v4 UUID的函数。这是我能够最接近的。我在十六进制，十进制，二进制，PHP的按位运算符等方面的知识几乎不存在。该功能可以生成有效的v4 UUID，直到一个区域。 v4 UUID应该采用以下形式： xxxxxxxx-xxxx- 4 xxx- y xxx-xxxxxxxxxxxx 其中y是8,9，A或B.这是函数失败的地方，因为它不遵守这个规则。我希望在这方面有比我更多知识的人可以借我一把，
