Traits in php–bible perspective
What are traits in php ?
Traits solves the problem where php classes can’t inhrerit behaviours or use properties, methods, etc from other classes except the parent class it extends to.
Traits in php makes a class have access to methods, properties in othe classes.
Let’s use the bible story to elaborate this: We are not native isrealites so by default we as “gentile class” can’t have any inheritance with the jews, but traits, Jesus Christ, has come to bridge this gap. Take for example :
The child class, isrealites extends (inherits) to the parent class, God
class isrealites extends God {
}Gentile class (actually, Gentile Nation) wants to have access to the abrahamic promises but can’t. Then Jesus Christ came in for us –Traits !
So create a trait class:
trait JesusChrist {
public function salvationPromise() {
return "the promise is unto you and to your children, children";
}
public function prosperityPromise() {
return "I will above all things that thou mayeth prosper even as thy soul prospereth ";
}
public function freedomFromSin() {
return "If the son shall make you free, you shall be free indeed";
}
}For gentiles to use this trait as well as inherit all the promises of Isrealite class, we provide a “Jesus Trait” for them.
// ....
class Gentiles {
use JesusChrist;
}
$gentile = new Gentiles();
//pick one promise
echo $gentile->freedomFromSin();A full code will look like this:
trait JesusChrist {
public function salvationPromise() {
return "the promise is unto you and to your children, children";
}
public function prosperityPromise() {
return "I will above all things that thou mayeth prosper even as thy soul prospereth ";
}
public function freedomFromSin() {
return "If the son shall make you free, you shall be free indeed";
}
}
class Gentiles {
use JesusChrist;
}
$gentile = new Gentiles();
//pick one promise
echo $gentile->freedomFromSin();Traits are used to access methods and properties that extend the capabilities of a class.
