PHP 4 - variables inside class

Question

I have a class like

class blah extends blahblah{

  private $variable = '5';

  function somefunction(){
    echo $variable;
  }
}

this works in php 5, but not in php 4. I get a error:

Parse error: parse error, unexpected
T_VARIABLE, expecting T_OLD_FUNCTION
or T_FUNCTION or T_VA....

I also tried with public and static. Same error.

How can I add a variable inside that class that I can access from all class functions?

Answer 1

private is not a valid keyword in PHP 4 change it to var $variable = '5'; also the function is wrong it should be...

class blah extends blahblah{

  var $variable = '5';

  function somefunction(){
    echo $this->variable;
  }
}
