using arrays in classes - problems geting an array's value

thehedgehog

class testClass {
     var $blah; // defining my array*

 function setArrayValue($value) {
      $this->blah[] = $value;
 }
}

$newObject = new testClass;
$newObject->setArrayValue("foobar");
echo "$newObject->blah[0]"; 

//last line will produce array[0] to browser

simple example to illustrate what i'm trying.

*i've also tried doing:

var $blah = array();

within the class, but no love there either.

use:
echo $newObject->blah[0];

Hi,

alternatively you can use

echo "{$newObject->blah[0]}";

too weird. i've known about the explicitly wrapping variables in curlys for some time, but i've never actually come across a scenario where i needed to use it.

thanks both 🙂

And thanks from me... had me pulling what little hair I had out. And from a shell scripting background I should have known better!

<?php

class doArray {

var $a;

function test_arr($ar)
{
	echo "doing something<br>";
	while( list($key,$val) = each($ar) ) 
{ 
		echo "$val => $key <br>";
    $this->a[$val] = $key;
} 
}

function echo_arr() {
echo "doing something else<br>";
	for ( $i=0; $i<3; $i++ ) {
	echo "array $i = {$this->a[$i]} <br>";
	}
}

}

echo "starting<br>";
$artest = new doArray();

$artest->test_arr(array('yes'=>0,'it'=>1,'works'=>2));

$artest->echo_arr();
echo "finishing<br>";

returns...

starting
doing something
0 => yes
1 => it
2 => works
doing something else
array 0 = yes
array 1 = it
array 2 = works
finishing
