so it's probably not str_replace what's slowing you down, but
the loops? Maybe they could be optimized some more... (I don't
want it sound like I'm saying it's your fault, or that you're
a bad programmer, just to make it clear.)
No it's not the loops it's just PHP being as slow as it always is.
The loop looks something like this:
$str = "lots of text";
$arr = array( "a", "b", "c", "d" );
$vals = array( "e", "f", "g", "h" );
$a = each( $arr );
$b = each( $vals );
while( $a $b )
{
str = str_replace( $a[1], $b[1], $str );
$a = each( $arr );
$b = each( $vals );
}
Anyways this is beyond the point which is that these three functions
(str_replace, ereg_replace and preg_replace) does the same things but
varying complexity, but their usage is not the same. This is just a
matter of consistency amongst functions.
When I want to replace a simple string with another string I use
str_replace, when I want to replace a regular expression with a string
I use ereg_replace or preg_replace. However when I want replace lots
of simple strings I must use preg_replace due to speed. This is not
good.
So I ask again:
Are there any plans to make str_replace and ereg_replace take arrays
as parameters as well, in the same manner as preg_replace does?
(a simple yes or no will suffice)
Or do I have to do this myself?

[PHP-DEV] string replacement
Is there any plans to extend str_replace and ereg_replace to accept arrays in the same manner as preg_replace does? At the moment using preg_replace on arrays are faster than iterating trough the arrays and passing them to str_replace, which is bad. -- - Jan Borsodi [EMAIL PROTECTED] - Systems Engineer @ eZ systems - Web: http://ez.no QtVu: http://www.qtvu.org - RegExplorer: http://regexplorer.sourceforge.net EMacro: http://emacro.sourceforge.net - Apollo: http://www.apolloplayer.org -- PHP Development Mailing List http://www.php.net/ To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, e-mail: [EMAIL PROTECTED] To contact the list administrators, e-mail: [EMAIL PROTECTED]

Cynic [EMAIL PROTECTED] writes: why is it bad? Why? Because it's quite normal for functions like str_replace to be *much* faster than preg_replace, but since str_replace on arrays is slower (due to iterating over them using PHP code) you have to use preg_replace. I'll happily use preg_replace whenever I need to do some Regular Expression replacement, but when I want to do normal text replacement I expect str_replace to give me the same flexibility as preg_replace.
