PHP - Need Help Using Namespaces
Hey Guys. I am new to using namespaces. I am trying to use it on the code below but it keeps giving me an error message saying Class 'lesson_one\Lecture' not found
I am not sure what I am doing wrong here... I have provided an example below. I know there is a duplicate conditional statement. But I am just working with this code to test out the namespace.
Any help would be really appreciated!
namespace lesson_one;
abstract class Lesson {
protected $duration;
const FIXED = 1;
const TIMED = 2;
private $costtype;
function __construct($duration, $costtype=1) {
$this->duration = $duration;
$this->costtype = $costtype;
}
function cost(){
switch($this->costtype) {
case self::TIMED:
return (5* $this->duration);
break;
case self::FIXED:
return 30;
break;
default:
$this->costtype = self::FIXED;
return 30;
}
}
function chargeType() {
switch($this->costtype) {
case SELF::TIMED:
return "hourly rate";
break;
case self::FIXED :
return "fixed rate";
break;
default:
$this->costtype = self::FIXED;
return "fixed rate";
}
}
}
class Lecture extends Lesson {
}
class Seminar extends Lesson {
}
//echo Lesson::FIXED;
$lecture = new \lesson_one\Lecture("5", Lesson1::FIXED);
echo $lecture->cost(). "<br>";
echo $lecture->chargeType(). "<br>";
Similar TutorialsDoes the concept of a "Namespace" exist in PHP? If so, how do you use them? This is a snippet from ASP.NET that made me ask this question... Quote <%@ Import Namespace="System.Data" %> <%@ Import Namespace="System.Data.SqlClient" %> TomTees when trying to call
get_class($this)it will return the namespace of my class Application\Models\User_Model But what im really after is just User_Model... is there a way of actually getting the class name and not the namespace itself? thought i'd ask before making a class for that...thank you
I have to be doing something wrong here, but so far Googling hasn't helped. Take a look he
https://demo.envrin.com/api/classes/apex.app.msg.emailer.html#method_send
The doc-block is correct, or at least as far as I can tell it is, character-by-character. I'm blind though, but have tried different combinations of things like "String" instead of "string" or "@Param" instead of "@param". Made sure the ends of the @param lines ende din a period, and that seemed to help a little.
Nonetheless, why does it keep adding the namespace to everything in front of "string" like that? Any why are the paramaters section all screwed up?
Any help would be appreciated. Thanks!
Hi,
Well, I'm having this
The formatter threw an exception while trying to deserialize the message: Error in deserializing body of request message for operation 'GetSomething'. End element 'Body' from namespace 'http://schemas.xmlso.../soap/envelope/' expected. Found element 'param1' from namespace ''.
The soapclient request itself is something with multiple namespaces, like :
<aaa xmlns="namespace1"> <bbb xmlns="namespace2" xmlns:i="http://www.w3.org/20...hema-instance"> <requestparams>xxxxx</requestparams> </bbb> </aaa> So far I think this may got to do with multiple namespaces, so I've been trying to figure out how to deal with this for hours to no avail. Anyone can shed a light into this problem ? Thanks in advance, I'm not entirely sure what is wrong with me, but I'm having a super difficult time understanding namespaces.
I have 2 primary classes
# Resides within class.DataTypeBase.php
namespace DTB\Base;
class DataTypeBase {
protected $name = '';
protected function getName() {
return $this->name;
}
protected function setName($name) {
$this->name = $name;
}
}
# Resides within class.DataType.php
namespace DTB;
class DataType extends DataTypeBase {
public function process_data(){
....
}
}
I then have a third file that contains approximately 9 different classes that further extend DataType
# Resides within class.DataTypes.php
namespace DataTypes;
class Silver extends DataType {
public function differ($type) {
....
}
}
The namespace system seems to work for class DataTypes, but with the class Silver I get an error message saying that the class DataType does not exist. From what I read online, and using the example above I figured the "extends DataType" may have to be "extends \DTB\DataType" but it results in the same error message.
I'm not entirely sure what I need to do for this to work properly
