Hello there,
I have about 30 markers in the text which need to be replaced with the value
of a variable or an array.
Common sense comes up with
eregi_replace("!one!","blah",eregi_replace("!heh!",'foobar',eregi_replace("b
lah","ho-ho-ho",text)));
The list above could go on and on... I'm sure there are better ways to
replace many markers or spans of text with something else. A loop? Something
even more easier and better?
Thanks,
Lauri

Re: [PHP] multiple replaces...
If you only want to replace strings, then drop the regular expression functions! (a
common mistake)
Use for example str_replace, or in this case, strtr which is better because it accepts
an array as replacement pattern.
For example:
$foo = array("foo" => "apple", "bar" => "banana");
$string = "I like foos and bars";
$string = strtr($string, $foo);
echo $string;
output:
I like apples and bananas

Re: [PHP] multiple replaces... (2)
And so does preg_replace() if you need any regular expressions. Though str_replace() is probably faster when this is not the case. http://www.php.net/manual/en/function.str-replace.php http://www.php.net/manual/en/function.preg-replace.php bvr. -- PHP General 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]
Re: [PHP] multiple replaces...
No need to loop. str_replace() already supports arrays! check the manual. bvr. On Sat, 12 Jan 2002 12:57:10 -, DL Neil wrote: >Yes, I thought about that.

Re: [PHP] multiple replaces...
Yes, I thought about that. But, what should I do when the markers are absolutely NOT in any sequence. =sequence would matter if it was possible that one of the markers could replace some text and that replacement subsequently became the marker for a further replacement ... nightmare=recursion! I also thought about something like $replace[1][1] = "!one!"; //marker $replace[1][2] = "hehee"; //replace with $replace[1][1] = "test"; //marker $replace[1][2] = "foobar"; //replace with $replace[1][1] = "repl"; //marker $replace[1][2] = "humpty-dumpty"; //replace with $replace[1][1] = "blah"; //marker $replace[1][2] = "boo"; //replace with Now, when I would do a loop thingie that goes through all those, then it would be a pretty nice and compact solution... What about speed issues regarding this solution? =check out string functions. On simple stuff they will beat RegEx for speed hands down - but watch out if case-sensitivity is relevant. =dn -- PHP General 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]

I don't think speed will be an issue unless you have thousands of
markers, in which case you'll need to re-think the whole thing.
Can you not put all of your markers in an array like
$markers=array("m1", "m2", "m_whatever");
and all your replacements likewise
$replace=array("r1", "r2", "r_whatever");
and then loop through like that?
If not, explain a little more about the context of the problem and let's
see if we can come up with an alternative.
