Örnek 1 - ReflectionClass::getConstant() kullanımı
<?php
class Örnek {
const C1 = false;
const C2 = 'Ben bir sabitim';
}
$reflection = new ReflectionClass('Örnek');
var_dump($reflection->getConstant('C1'));
var_dump($reflection->getConstant('C2'));
var_dump($reflection->getConstant('C3'));
?>Yukarıdaki örneğin çıktısı:
bool(false) string(15) "Ben bir sabitim" bool(false)
If the $name constant doesn't exist in the targetted class the function returns bool(false), not empty nor null but false (you to test with "==="
$constFounded = false ;
$this->currentlangClass = new ReflectionClass($langFile);
$this->currentlangClass->getConstant($constant);
if($myConst !== false){
$constFounded = true ;
}The "getconstant" method can be used to get the value associated with a constant
of a particular class that you are examining.
The following code snippet shows this:
<?php
class Test{
const ONE = "Number one";
const TWO = "Number two";
}
$obj = new ReflectionClass( "Test" );
echo $obj->getconstant( "ONE" )."\n";
echo $obj->getconstant( "TWO" )."\n";
?>
output:
Number one
Number two
