[SOLVED] easy replace

[dtdetu]

hello can somebody help me how i can change

 

page?id=1

to

page

 

value of id changes everytime, like id=2 id=4 etc

thanks

[rhodesa]

can you elaborate on what you are trying to accomplish? is the first part in a string? are you trying to just remove the id attribute or strip everything after the question mark?

i am tryign to get the page name of the page but i want to get the page name alone like this page is

index.php?id=12 i want to get index , can u also give me the code for get page name thanks

dtdetu, I mean no offense when I say this, but I would strongly recommend taking some time to learn regex basics. It isn't hard to learn per say.. a little intimidating at first, but once you get past the basics, you realise how useful regex can be.

And if all you want is the breakdown of the url, you can use parse_url instead:

 

example:

 

$str = 'index.php?id=12';
$parse = parse_url($str);
echo '<pre>'.print_r($parse, true);

 

Output:

Array
(
    [path] => index.php
    [query] => id=12
)

thank you all , there is too much to learn and not enough time thanks

[dtdetu]

i used this code and works , incase someone needs.. thanks

   $str = $_SERVER['REQUEST_URI'];
     $parse = parse_url($str);
       $parse[path]=str_replace('/','',$parse[path]);
       $parse[path]=str_replace('.php','',$parse[path]);
     return $parse[path];

Poor excuse which can only last so long... No one has all the time to learn.. we make the time to do so. Otherwise, you are at the mercy of everyone else.. a pity really. Don't be lazy.

See, now that I see you post a code snippet, I can see you are making effort.. good for you.

 

Here is my take on this:

 

$str = 'index.php?id=12';
$parse = parse_url($str);
preg_match('#^([^.]+)#', $parse['path'], $match);
echo $match[1];

 

Output:

index

[dtdetu]

thanks

[nrg_alpha]

Or if you wanted to use preg_replace instead:

 

$str = $_SERVER['REQUEST_URI'];
$parse = parse_url($str);
$parse['path'] = preg_replace('#^/([^.]+).*#', "$1", $parse['path']);
echo $parse['path'];

[nrg_alpha]

Actually, come to think of it, we can just get that first part even without the parse url bit:

 

$str = $_SERVER['REQUEST_URI'];
$str = preg_replace('#^/([^.]+).*#', "$1", $str);
echo $str;

[dtdetu]

yes but if we dont use parse url then it gets the ?id=2 part too and other $_GETs

 

[nrg_alpha]

yes but if we dont use parse url then it gets the ?id=2 part too and other $_GETs

 

It should work.. here is the breakdown of the preg:

 

'#^/([^.]+).*#', "$1", $str

 

Basically, this is saying: At the start of the string ( noted by the ^ character), after the /, capture anything that is not a dot, and replace the entire thing with just what was captured.. so if I were to use '/someFile.php?id=7' to pretend it is the end results of $_SERVER['REQUEST_URI'], I plug this into the last snippet example like so:

 

$str = '/someFile.php?id=7';
$str = preg_replace('#^/([^.]+).*#', "$1", $str);
echo $str;

 

The regex will only use what it captured.. so in this case, the initial /, and everything (including and after) the dot character is replaced with what is inside those brackets.. so in the above case, the result would be

 

someFile

 

Try it out.

[nrg_alpha]

You know what? Even easier (now that I think about it.. [man I must be brain dead today]), is to use pathinfo like so:

 

$str = $_SERVER['REQUEST_URI'];
$x = pathinfo($str);
echo $x[filename];

 

So let's pretend $_SERVER['REQUEST_URI'] = /someFile.php?id=7, once again, the end result will be

 

someFile

 

I think this snippet is the best way to go.

hehe thank you:) dont think more about this its ok:)

[nrg_alpha]

ok done deal.
