I am trying to use this in my page class. I only just started using objects in PHP so I'm still a little clueless (but learning as much as I can). This is in my page() function (so called when there is a new instance of page) set_error_handler('$this->appendError'); This is causing an error Warning: set_error_handler() expects the argument (appendError) to be a valid callback Now h
我正尝试在我的页面类中使用它。 我只是刚开始在PHP中使用对象,所以我仍然有点无知(但尽可能多地学习)。 这是在我的page()函数中(当有新的页面实例时调用) set_error_handler('$this->appendError'); 这是造成错误 警告:set_error_handler()期望参数(appendError)是有效的回调 现在如何设置一个类内部函数,同时将该函数作为字符串传递。 这不可能吗? 我应该使用一个普通函数,然后调用类函数并通过所有
i have code like this, <input id="email" name="email" type="email" placeholder="email" class="form-control input-md" required="" /> and my action form php $email=$_POST["email"]; when i type echo $email, it not showing what i input. but if i change <input id="email" name="email" type="text" placeholder="email" class="form-control input-md" required="" /> (type=text)
我有这样的代码, <input id="email" name="email" type="email" placeholder="email" class="form-control input-md" required="" /> 和我的行动形式php $ email = $ _ POST [“email”]; 当我输入echo $ email时,它不显示我输入的内容。 但如果我改变 <input id="email" name="email" type="text" placeholder="email" class="form-control input-md" required="" /> (type=text) 它显示我输入的内容,类
I'm having trouble with php script that I've created to insert instances into a database, however I'm getting a trivial output and i dont know how to fix it. the code is: <?php try{ $user = 'root'; $pass = null; $pdo = new PDO('mysql:host=localhost; dbname=divebay', $user, $pass); $pdo->setAttribute(PDO::ATTR_ERRMODE, PDO::ERRMODE_EXCEPTIO
我遇到了我创建的用于将实例插入到数据库中的php脚本的问题,但是我得到一个简单的输出,我不知道如何解决它。 代码是: <?php try{ $user = 'root'; $pass = null; $pdo = new PDO('mysql:host=localhost; dbname=divebay', $user, $pass); $pdo->setAttribute(PDO::ATTR_ERRMODE, PDO::ERRMODE_EXCEPTION); $username = $_POST['username']; $password = sha1(
i often run into a problem when variables/attributes have the wrong type. The Problem is that it is hard to trace since my PHP (5.3) just crashes, does not put out an error or even write to the error log (*1). It just crashes. I think accessing a string like an array shouldn't be untraceable should it? I mean, PHP is not C right? Is there a way to change this behavior or some sort of b
当变量/属性的类型错误时,我经常遇到问题。 问题在于它很难追踪,因为我的PHP(5.3)刚刚崩溃,没有发出错误,甚至没有写入错误日志(* 1)。 它只是崩溃。 我认为访问像数组这样的字符串不应该是难以追踪的吗? 我的意思是,PHP不是对的? 有没有办法改变这种行为或某种最佳实践来解决这个问题? 除了始终检查每个变量,因此写入5倍以上的代码? [更新] :好的,如果我简化了Zend之外的代码,它似乎工作。 它肯定是
I have a function that 'echos' before returning an array. When assigning that function to a variable like below, it executes the function outputting the echo. Is this expected behavior as I thought assigning to a variable should only do just that, assign? Thanks function check($link) { //..... echo "some text "; return $array; } $test = check($link); When you assign a functio
在返回数组之前,我有一个“回声”的函数。 当将该函数分配给像下面这样的变量时,它执行输出回声的函数。 这是预期的行为,因为我认为分配给一个变量应该只做到这一点,分配? 谢谢 function check($link) { //..... echo "some text "; return $array; } $test = check($link); 当你将一个函数赋值给一个变量时,php实际上正在执行的函数是获取其返回值,然后将该值赋予该变量。 所以php执行你的函数(因此执行ec
I'm trying to get the variables from a $_GET request the request is like /markers/var1/var2/var3/var4 the route file is as follows: Markers: pattern: /markers/{slug} defaults: { _controller: ngNearBundle:Markers:index } First question is : does index method need to be an action method ? "indexAction" the method will output json. how can I get the value of var1 and var2 etc .
我试图从$ _GET请求获取变量,请求类似于/ markers / var1 / var2 / var3 / var4,路由文件如下所示: Markers: pattern: /markers/{slug} defaults: { _controller: ngNearBundle:Markers:index } 第一个问题是: 索引方法是否需要是一个动作方法? “indexAction”方法将输出json。 我怎样才能得到var1和var2等的价值......? 谢谢 ! 1) 是的,它需要是控制器内部的一个动作。 如果你返回一个JSON体,你可以使

这两个PHP语句是否做同样的事情?: $o =& $thing; $o = &$thing; Yes, they are both the exact same thing. They just take the reference of the object and reference it within the variable $o . Please note, thing should be variables. They're not the same thing, syntactically speaking. The operator is the atomic =& and this actually matters. For instance you can't use the =&am
这两个PHP语句是否做同样的事情?: $o =& $thing; $o = &$thing; 是的,他们都是完全一样的东西。 它们只是取对象的引用并在变量$o内引用它。 请注意, thing应该是变数。 从句法上讲,它们不是同一个东西。 运算符是atomic =& ,这实际上很重要。 例如,你不能在三元表达式中使用=&运算符。 以下两种都不是有效的语法: $f = isset($field[0]) ? &$field[0] : &$field; $f =& isset($field[0])
This function is not working for me. I think it is isset($_GET['success']) that's not working but I'm really not sure. the problem is it doesn't print anything ever. And without if(isset($_GET['success'])) it only prints "username taken" Please help? <?php if(isset($_GET['success'])) { $success=$_GET['success']; if($success=='yes') { echo "<center&g
这个功能对我不起作用。 我认为这是isset($ _ GET ['success'])不起作用,但我真的不确定。 问题是它不会打印任何东西。 没有if(isset($ _ GET ['success']))它只打印“用户名采取”请帮助? <?php if(isset($_GET['success'])) { $success=$_GET['success']; if($success=='yes') { echo "<center><font color='red'>Comment Posted!</font></center>"; } else { echo "<
What does $_GET return when the index is not set? (Couldn't find anything in php manual about $_GET.) I wrote this to check, if the $_GET['id'] isset - and if it is not, set $id to false: <?php $id = (isset($_GET['id'])) ? $_GET['id'] : false ?> $_GET is just an ordinary array, so it behaves exactly the same as any other array. This means, it will return NULL to the varia
索引未设置时,$ _GET返回什么? (在php手册中找不到任何关于$ _GET的内容。) 我写这个来检查,如果$ _GET ['id'] isset - 如果不是,则将$ id设置为false: <?php $id = (isset($_GET['id'])) ? $_GET['id'] : false ?> $ _GET只是一个普通的数组,所以它的行为与任何其他数组完全相同。 这意味着,当你调用一个不存在的索引时,它会将NULL返回给变量并引发“undefined index”通知。 使用$ _GET唯一需
