[SOLVED] Variables in a string inputted into Class Method

[WBSKI]

I am not sure what the term is for this so I will do my best to explain my problem.

 

I am calling a method which prints out a mysql table, one variable is required by the function: $template

 

$template looks like this: "<p>$row[name]</p>

 

So the method call would look like this:

$theclassobject->echotabletemplated("<p>$row[name]</p>

 

The problem is that I want the $row to be the referencing variable within the method, rather than the $row  variable from where the method is called, which is not in the same class. Is this possible?

Its possible, but not at all pretty. Firstly, you need to make sure that the argument passed to echotabletemplated() is a single quoted string so it won't be interpolated from within the calling code. There is no way to inforce this in php or any other language I'm aware of.

 

Once that is done, you can use http://php.net/eval]eval[/url]() to parse the passed in string as php within the echotabletemplated() method.

 

Having pointed out how it may be possible I would urge you to rethink your design. This is never going to hold water.

So is $row a property inside the class?

 

 

<?php

class foo {

    public function echo($var){
        echo $this->{$var};
    }

}

$foo = new foo();
$foo->echo('testVar');
// will display $foo->testVar

?>

$row is within the method called

Ok, the eval worked perfectly. Thanks guys!

I would strongly reconsider your design implementation. You should not know what properties are within an object if they are not public.
