3 nested str_replace statements, more efficient method?

[phpchick]

I'm doing this currently but I imagine there has to be a better way of doing it?


<?php echo str_replace("+", "", str_replace("%", "%)", str_replace('"', '', $stock[8]))); ?>

Unfortunately that depends entirely on what you are wanting to do.
String replacement is much better performance wise the pattern matching. However, str_replace in sequence will always apply ltr, so first you replace " with nothing, then you replace % with %), then you replace + with nothing. In this particular situation, you can likely get away with a simple:

PHP Code:

echo str_replace(array('+', '%', '"'), array('', '%)', ''), $stock[8]); 


The thing to be careful with with str_replace is that any replacement you do doesn't impact on the next set (unless that is the intent of course). So if I were to replace + with '%' and '%' with '%)', then every + would become %) when the intent may be to replace it with %.
