I have a bit of code:

 

while($i < mysql_num_fields($result)) {
			$meta = mysql_fetch_field($result,$i);
			echo $i . ". " . str_replace($notallowed,"",$meta->name) . "<br />";
			$i++;
			}

 

what does $meta->name do exactly?

[Mchl]

It's accessing property name of object $meta. It's probably most basic part of object oriented programming.

 

 

See http://pl.php.net/manual/en/language.oop5.php for more info on objects and classes.

[dennismonsewicz]

does it work the same as this:

 

$results = mysql_fetch_array($sql);

		$upload_name = $results['upload_name'];
		$size = $results['size'];

 

could you say $results->upload_name?

 

[PFMaBiSmAd]

Yes, if you use mysql_fetch_object() instead of mysql_fetch_array().

[nrg_alpha]

From what one book I read, it described it like this... consider the '->' to be the equivalent to 'has a'.

 

Therefore:

$meta->name

is like saying: this object 'has a' property called 'name'. For better or worse, I have personally found this 'has a' to be quite nice to think of it as. This description is not meant to be hyper accurate from a computer science standpoint, but rather to looesly illustrate.

thanks for everyone's help. I have a much better understanding of it now!
