preg_replace VS. eval speed

[snorider]

Just a short question. Is there a speed difference between eval() and preg_replace when used in a loop?

It would be used to either eval a string like:

"My name is $name"

Or in a preg_replace string like:

"My name is <DATA:name>" Where <DATA:name> is replaced with $name.

Sorry it's so short, but trying to explain the whole thing would be difficult and most likely confusing since I'm not very good at explaining things 🙂

Any input would be great,

Thanks in advance
