[SOLVED] str_ireplace

[Renlok]

is there another way of doing case insenstitive string replaces other than with str_ireplace? Im making a open source script and for the word filter i need it to be case insensitive but i dont want to use str_ireplace as its a php5 function and i want it to work on php4

 

anyone have any ideas?

[.josh]

could use preg_replace.

[Renlok]

yes that works fine thakyou

[redarrow]

i am not sure but has php4 got to have preg_replace enabled in php.ini if so use eregi_replace()

[Daniel0]

i am not sure but has php4 got to have preg_replace enabled in php.ini

Yes.

 

if so use eregi_replace()

No.

[.josh]

i am not sure but has php4 got to have preg_replace enabled in php.ini if so use eregi_replace()

 

Yes preg_replace is enabled by default.  Don't use eregi_replace or any posix functions (ereg_xxx) as they are not going to be part of the core as of php6.  Why?  Because they are stupid and inferior.

if you want the letters to be uppercase then use strtoupper() function.

<?php

$letters="abcdefg";

echo" ".strtoupper($letters)."";

?>

 

yes dont use eregi due to it being tured off in php6 but your working on a php4 script i notice or is it a script that can be used on php4 and  php5 and php6 if so use preg_repalce()

[.josh]

okay redarrow, but if you strtoupper then you won't preserve the case of the rest of the string. 

[Daniel0]

yes dont use eregi due to it being tured off in php6 but your working on a php4 script i notice or is it a script that can be used on php4 and  php5 and php6 if so use preg_repalce()

 

Could you rephrase that, please? It's not legible.

[redarrow]

here a example mate encase you dont no how to get it to work.

 

like i say still got to use strtoupper mate

<?php

$letters="abcdefg";


$letters = preg_replace("/[A-Za-z]/e", 'strtoupper("$0")', $letters, 100); 


echo $letters;

?>

 

dan all i am saying is that if the user is going to create a script for php4 only then he can use eregi_relace()

[.josh]

there's no such thing as an 'e' modifier.  I assume maybe you meant 'i' except that you already cover capital and lower case in your char class so really, I have no idea what you intended to do with that 'e'

[redarrow]

When using the e modifier, this function escapes some characters

(namely ', ", \ and NULL) in the strings that replace the

backreferences. This is done to ensure that no syntax errors arise

from backreference usage with either single or double quotes (e.g.

'strlen(\'$1\')+strlen("$2")'). Make sure you are aware of PHP's

string syntax to know exactly how the interpreted string will look

like.

 

Seems a stripslashes to finish up is what you need.

[redarrow]

there is a e modifier just for backslash yes can use \\

[Daniel0]

dan all i am saying is that if the user is going to create a script for php4 only then he can use eregi_relace()

 

But he could also use the PCRE functions, which he, according to the manual, should. That is assuming he is using 4.2+, but seeing as support for the 4.x branch is discontinued and the latest PHP4 version is 4.4.9 it would be logical to assume that's not the case.

 

<?php

$letters="abcdefg";


$letters = preg_replace("/[A-Za-z]/e", 'strtoupper("$0")', $letters, 100); 


echo $letters;

?>

 

That's a stupid example and what is it even supposed to be showing?

look e up mate it there.

[redarrow]

so what your solution i ant got another with preg_repalce show us mate.

[.josh]

ah that's a preg_replace only modifier.  Okay but still, I don't really see why you need that in there.
