Replacing unwanted symbols in string 1

[overyde]

Hi,

If I want to delete unwanted characters from my variable (say info from a form), is this the best way to do this:

$restricted = array("!", "@", "#", "$", "%", "^", "&", "*", "/", "(", ")", "|", "\\");

$output = str_replace($restricted, "", "$input");
$input = "oranges &*/()|\* and lemons";
print "$output";

This is certainly a good way to do it.
An alternative is always a regular expression. Here then comes the 'timing' issue which is that regular expressions usually have a timing advantage only if the same expression is used multiple times. However, this is quite theoretical as the amount of data parsed probably is small scale.
If you have a good server that is not taxed to its limits then either way should be fine.
