Passing a number of arguments on a sigle string

[rastacre]

Hi All,

 

I'm a newbe of the forum and of PHP in general.

 

I have a class items with no constructor but few functions that applies to it and most of the sub classes.

 

then i have classes extending it publisher, category, author and book. They both have constructors:

 

publisher and category, have the same constructor with one argument for $name

 

author' arguments are $name and $surname

 

and for book i have the following constructor:

 

__construct($category_id , $isbn , $name , $year , $author_id , $publisher_id , $price , $qty) 

 

now i'm trying to do this:

 

$type = 'book';
$attributes = "'1', 'qwerty123', 'The Title', '2000', '2', '3', '15.95', '12'";
$new_{"$type"} = new $type({$attributes});

 

i understand that

 

new $type({$attributes})

 

doesnt work, but i'd like to know if it's actually possible to pass the arguments with a single string interpreted not as the variable itself, but the variable's value....

 

i hope it makes sense the way i explained and I hope someone can shed some light on this... the PHP manual didn't help me too much.

 

Thanks in advance

No, its not possible to do it the way you have described. You would be best off sending your arguments within an array.

Yeah, send it as an array. I kinda asked the same question before.

 

Just send it as an associative array and use variable variables

 

$arr = array('a' => 1, 'b' => 2);

 

then you just loop through and set the vars

 

foreach($arr as $key => $val){

$$key = $val;

}

 

that will give you

$a which holds the value 1 and $b which holds 2

Thanks guys,

 

and emehrkay, thanks for the code, i thought that was the way to go, but i was still hoping for the string solution..

 

well I'll have to modify the rest of my classes as well

 

thanks again
