build an array of array in php [duplicate]

Question

I am trying to build an indexed array of array's in php, not a key value array of arrays, I keep getting parse error. Can you show me where my mistake is? Why is it that I can set the values of the singly dimensioned arrays but not $ax? Thanks!

<?php
class mdArray{
public $a0 = array('10','20','30','40','50','60','70','80','90');
public $a1 = array('11','21','31','41','51','61','71','81','91');
public $a2 = array('12','22','32','42','52','62','72','82','92');
public $a3 = array('13','23','33','43','53','63','73','83','93');
public $a4 = array('14','24','34','44','54','64','74','84','94');
public $a5 = array('15','25','35','45','55','65','75','85','95');
public $ax = array($a0,$a1,$a2,$a3,$a4,$a5);
}
?>

Which line has a syntax error? What is the exact error you get? — gen_Eric

@RocketHazmat - I'd imagine public $ax = array($a0,$a1,$a2,$a3,$a4,$a5); which is dependent on run-time information — Mark Baker

Why don't you do : class mdArray{ public $ax = array( array('10','20','30','40','50','60','70','80','90'), array('11','21','31','41','51','61','71','81','91'), array('12','22','32','42','52','62','72','82','92'), array('13','23','33','43','53','63','73','83','93'), array('14','24','34','44','54','64','74','84','94'), array('15','25','35','45','55','65','75','85','95'), ); } — Mark Baker

@MarkBaker I am writing a function that takes small values to create a string with implode. I add a single charter to the end of the string, I do this for every array, then I implode all the strings together into one string, I'm trying to pass only one parameter into the function — demuro1

It's probably this line:

public $ax = array($a0,$a1,$a2,$a3,$a4,$a5);

You need to do that in your constructor:

<?php
    class mdArray{
        public $a0 = array('10','20','30','40','50','60','70','80','90');
        public $a1 = array('11','21','31','41','51','61','71','81','91');
        public $a2 = array('12','22','32','42','52','62','72','82','92');
        public $a3 = array('13','23','33','43','53','63','73','83','93');
        public $a4 = array('14','24','34','44','54','64','74','84','94');
        public $a5 = array('15','25','35','45','55','65','75','85','95');
        public $ax;

        function __construct(){
            $this->ax = array($this->a0,$this->a1,$this->a2,$this->a3,$this->a4,$this->a5);
        }
    }
?>

This declaration may include an initialization, but this initialization must be a constant value--that is, it must be able to be evaluated at compile time and must not depend on run-time information in order to be evaluated.
