Var Replacement

[exze]

Hello,

 

I am trying to get a string and then replace each {NO} where NO is a number

 

For example the string I am replacing

 

You have {0} steps left {1} {2} {3}

 

The function I am parsing it through

 

public static function parse($string, $array = array())
{
if(empty($array))
{
return $output;
}

for($i=0;$i<count($array);$i++)
{
$output = str_replace('{'.$i.'}', $array[$i], $string);
}

return $output;
}

 

The PHP echo

 

 echo Lang::parse($lang['quest']['steps_left'], array('3', '2', '3'));

 

What is turns out to be

 

You have {0} steps left {1} 3 {3}

 

 

Any help? Simply it needs to replace all {NUMBERS} with the array so {0} would be 3 {1} would be 2 other solutions to make the function smaller will also be appreciated

 

Thanks in advance

It still only seems to replace the last var for some reason :s

Every time you set $output you're using $string in the replace function. So the last time it sets $output = the string replacing the last one only.
