Replce except text between

[prokhaled]

How can I replce string with another string except string between [E] and [/E]

for example: In This string
$Text="Hi how Are you [E] A A A [/E] Fine A A [E] A any text A [/E]";


I want to replce A with B but ignore A letter that between [E] and [/E]

How can i do that ?

Kinda like how vBulletin Code works?

$text = "Hi how Are you [E] A A A [/E] Fine A A [E] A any text A [/E]";
$text = preg_replace("/\\[E\\]([A])\\[\\/E\\]","B",$text);
echo $text; 

I am not sure if that is what you want, as your question is not very clear. Can you provide an example of how th output should look like?

[prokhaled]

$Text will be

$Text="Hi how Bre you [E] A A A [/E] Fine B B [E] A any text A [/E]";

that mean that all A string between [E] and [/E] will not change.

[cpradio]

It is easier replace the A in the [E] [/E] than outside of them. If I new more preg/reg expressions I would attempt it, but I am pretty novice at them.

I try your code .. but it give me this error :
Warning: No ending delimiter '/' found in C:\apache\htdocs\r.php on line 4

I have an idea how to do it, but I have to go to work. If no one's helped you by then, I'll give it a shot when I get home (around 12:00 EST)

[phpman]

<?php
$text1 = "Hi how Are you [E] A A A [/E] Fine A A [E] A any text A [/E]";
if (preg_match('/(.*) (\\[E\\])(.*)(\\[\\/E]) (.*) (\\[E\\])(.*)(\\[\\/E])/', $text1, $match)){
  
    $rep = str_replace("A", "B", $match[5]);
    $done = $match[1].$match[2].$match[3].$match[4].$rep.$match[6].$match[7].$match[8];
    
    echo "<p>".$done;
 
}else{
  echo "doesn't match";
}  
?>

Although I don't see the purpose of this.

[The Hobo]

By looking at your code, it will only work with the example text he gave, won't it?

I think he needs to to work no matter what the text is...

[The Hobo]

This is what I came up with:

<?php
    $test1 = "Hi how Are you [E] A A A [/E] Fine A A [E] A any text A [/E]";
    echo "Test1 = " . $test1 . "<br>After Function, = " . convert($test1) . "<br><br>";
    
    //THE FUNCTION:
    function convert($text) {
        if (!strpos($text, "[E]") === false) {
            do {
                $pos = strpos($text, "[E]", $epos);
                $ntext .= str_replace("A", "B", substr($text, $epos, $pos - $epos)); // . "<br>";
                
                $epos = strpos($text, "[/E]", $pos) + 4;
                $ntext .= substr($text, $pos, $epos - $pos);
            } while (!strpos($text, "[E]", $epos) === false);
            
        } else {
            $ntext = str_replace("A", "B", $text);
        }        
        
        return $ntext;
    }
?>

[prokhaled]

But i have another good idea

How can I replce A letter that between [E] and [/E]

I try the code of cpradio:

$text = preg_replace("/\[E\]([A])\[\/E\]","B",$text);

but it give me error.

the idea to replace A letter between [E] and [/E] with any strange string for example (!*!*!) and after that replace all A string with B string and after that replace strange string (!*!*!) with A letter

So what is the error in this code:
$text = preg_replace("/\[E\]([A])\[\/E\]","B",$text);

[phpman]

you are correct Hobo, that will only work with what string he had here.

prokhaled, Matt's code is missing a /

$text = preg_replace("/\[E\]([A])\[\/E\]/","B",$text);

[prokhaled]

I try that

<?
$text = "Hi how Are you [E] A A A [/E] Fine A A [E] A any text A [/E]";
$text = preg_replace("/\[E\]([A])\[\/E\]/","B",$text);
Echo $text;
?>

but no thing changed it's echo the same string without replace any thing

output:
Hi how Are you [E] A A A [/E] Fine A A [E] A any text A [/E]

Actually, it was Matt's idea...

So now you want the complete opposite?

[prokhaled]

opposite but short code.

so read through the manual and find out how to do something on your own for once.

now you know why I did it one way. why waste my time when he changes his mind so much and never does anything on his own.


$text1 = "Hi how Are you [E] A A A [/E] Fine A A [E] A any text A [/E]";

$text = preg_replace("/(A) /"," B ",$text1);
echo $text;

[The Hobo]

He's already asked an almost similiar question before...

Personally, my code does not work b/c I did not put time into checking it. I just wrote it as an example to go from.

If you do a search on many popular forums you will figure out how preg and reg expressions work. It isn't complicated it just takes time and patience.

Learning is not a bad thing to do. Depending on others however is.

[prokhaled]

I try it

$text1 = "Hi how Are you [E] A A A [/E] Fine A A [E] A any text A [/E]";
$text = preg_replace("/(A) /"," B ",$text1);
echo $text;

output was:
Hi how Are you [E] B B B [/E] Fine B B [E] B any text B [/E]

but it must be:
Hi how Are you [E] B B B [/E] Fine A A [E] B any text B [/E]

[phpman]

yup that is what I coded it for. now you have the means you can change it so it will change what you want.

Prokky, I think he's telling you to do it on your own.
