I'm new to working with classes in PHP
When I try to call $example->vars();
in the following class, the method changeVar()
within this method vars()
doesn't work. Why can't I call this?
<?php
class example {
private $var1;
public function __construct($var1) {
$this->var1 = $var1;
}
public function changeVar() {
$var1 = $this->var1;
$var1 = $var1 + 1;
return $var1;
}
public function vars() {
$var1 = $this->var1;
$var1 = 2;
$var1 = $this->var1;
echo "<br>made it here<br>";
$var1 = changeVar(); // Calls function changeVar() from above. This step doesn't work?
return $var1;
}
}
$example = new example(1);
echo $example->changeVar(); // Echos 2
echo $example->vars(); // Should echo 3?
?>
You need to call it like $this->changeVar()
inside class
