  php function
  In CakePHP there is a (quite fundamental) method called find. Most of the time this method would return an array but if you pass count as the first parameter the method would return a different data type – an integer.The method is allowed to return various data types.Isn’t that bad?

  php session variables if-statement phpmyadmin
  I am trying to create a user login page. Upon successful registration admins are assigned a value of “A” in my database and customers a “C”.

  When throwing a new exception is it best to simply return true if no exception needs to be thrown. Alternatively is it best to return false instead of throwing an exception. Im using php.

  php sqlsrv
  I have experience with mysql databases and have successfully connected to them with a couple dozen projects. Now, I’m having trouble connecting to a SQL Server 2007. This works: <?php phpinfo(); ?> and the sqlsrv and pdo_sqlsrv sections appear on this page. Here’s the code that I’m using to connect: <?php $serverName = “serverName\sqlexpress”; //serverName\instanceName $connectionInfo = array( “Database”=>”dbName”, “UID”=>”userName”, “PWD”=>”password”); $conn = sqlsrv_connect(

  php function types parameters casting
  This might sound like a silly question to many of you, but it keeps me wondering why PHP does not allow typecasting in its function parameters. Many people use this method to cast into their parameters:private function dummy($id,$string){echo (int)$id.” “.(string)$string }Orprivate function dummy($id,$string){$number=(int)$id;$name=(string)$string;echo $number.” “.$name; }But looking at many other programming languages, they accept typecasting into their function parameters. But doing this in PH

  php forms sed submit isset
  With a good deal of help I have created a script that edits a file on my VPS. It has been working great but I have one issue that has me totally stumped. When I need to adjust a value in the file to 0 it will not work. Pretty much any other value will work (i.e. value=”3″) except 0 (value=”0″). I’m very confused. I need to have the script change the color= value to color=0 I have no idea why 0 won’t work but any other number or letter will. Here is my code:<?php //Color$color = explode(“=”, t

  So I’m using .load() to call a CI method to load some code into a div like normal. CI loads the correct content into the div UNLESS there is a trailing slash on the class, then it actually ignores the method I am loading and loads the default method in that class … ie:THIS WORKS FINE:I call .load(‘http://domain.com/class/ajaxmethod’)from domain.com/class/methodTHIS DOES NOT:I call .load(‘http://domain.com/class/ajaxmethod’)from domain.com/class/method/It will actually load http://domain.com/cl

  php codeigniter inheritance protected
  I can use at least two basic ways to access a protected class method from a child class:parent::myMethod();$this->myMethod();If I don’t need to override it in the child class, in which case I would have to do this:function myMethod() {…parent::myMethod();… }which is the most recommended way to call it? I personally feel more comfortable using parent::myMethod() rather than $this->myMethod, because the first one immediately tells me this method is being inherited. But I’m not sure which wa

  mvc model view controller components
  Question number three in my quest to properly understand MVC before I implement it:I have two cases in mind:The primary application window needs to launch the preferences window. (One View invoking another View.) The primary Model for an application needs to access a property in the preferences Model. (One Model accessing another Model.)These questions are related in that they both involve communication across Model-View-Controller triplets, a topic that I haven’t found much discussion of in my

  view orientation
  I have unexpected problem with obtaining view’s dimensions on orientation change. I have my custom ImageView. In onDraw() method I get view’s width and height via getWidth() and getHeight() and using these values I scale and move my image. On activity’s onConfigurationChange() I simply call setImageBitmap(bmp);Everything is fine with that, but sometimes when orientation has changed, my ImageView in onDraw() still remember old values of it’s width and height. How can I update it?
