So, I want to split the REQUEST_URI in to pieces
Lets say I have a REQUEST_URI like this: /core/info/rules/
And want to display it like this: Core » Info » Rules
Any help or examples are appreciated :)
$uri=trim($uri,'/');
$uri=str_replace("/"," >> ",$uri);
$uri=ucwords($uri);
DEMO
Strip the first and last slash with trim() and then str_replace the leftover slashes with a right guillemet (» in HTML).
you can use str_replace function for this task..
i.e: `str_replace("/",">>","/core/info/rules/");`
Try this..Its may helpfull to you.
Thanks.
I would probably throw it into an array so you can iterate over it, add links to the navigation, etc
$nav = explode('/', $_SERVER['REQUEST_URI']);
array_shift($nav); // to remove the initial empty record

I have a page at:
http://somewebsite.com/1234/test/
How do I get the 1234 extracted from it with a PHP regex?
Don't use RegEx use parse_url() and explode().
For one level up, use dirname()
I like to avoid regex if I don't need it, so I would recommend you do it this way:
$url = explode("/", $_SERVER['PHP_SELF']);
Then you can reference the part of the url that you want using this:
$url[1]
If you need/want to use regex, I'll think about it for a second and try to post a solution later.
To just get the one above you can use
echo dirname("http://www.google.com/cake/lol");
Outputs
http://www.google.com/cake
Or for just the bit between the / and / you could do
var_dump(explode("/", "http://www.google.com/cake/lol"));
Or in regex
preg_match_all('#/([^/]*)/#',$sourcestring,$matches);
Perform regex on $_SCRIPT['REQUEST_URL'] or split it by '/' and get the first element => 1234
If the PHP was triggered by launching that URL, then these will probably be true:
$_SERVER['REQUEST_URI'] == "/1234/test/"
dirname($_SERVER['REQUEST_URI']) == "/1234"
basename(dirname($_SERVER['REQUEST_URI'])) == "1234"
preg_match(".*\/(\w+)\/(\w+)\/", "$url", $matches);
The parent directory is $matches[1].
I have this url (several similar ones)..
images/image1/image1.jpg
images/images1/images2/image2.jpg
images/images2/images3/images4/image4.jpg
I have this regex: but I want it to strip away the image name from the string:
<?php $imageurlfolder = $pagename1;
$imageurlfolder = preg_replace('/[A-Za-z0-9]+.asp/', '', $pagename1);?>
the string would look like the url's above images/images2/images3/images4/ but without the image4.jpg
hope you can help
Thanks
For this particular purpose function dirname() would be sufficient:
<?php echo dirname('images/images2/images3/images4/image4.jpg'); ?>
Would return:
images/images2/images3/images4
I think you can use the dirname function
for instance (from that page)
dirname("/etc/passwd")
would print
/etc
A quite straightforward way to do it:
preg_replace("#(?<=/)[^/]+$#","",$your_string);
It will remove everything between the last / and the end of the string.
Edit: as many peopole pointed out, you can also use dirname which might proof faster…
Hi all i know preg_replace can be used for formatting string but
i need help in that concerned area
my url will be like this
www.example.com/en/index.php
or
www.example.com/fr/index.php
what i want is to get
result as
www.example.com/index.php
i need it in php code so as to set in a session
can anyone please explain how ?
preg_replace('/www.example.com\/(.+)\/index.php/i', "www.example.com/index.php?lang=$1", $url); will do the thing
This is one way to do it:-
$newurl = preg_replace('/\/[a-z][a-z]\//', '/', $url);
Note that the search string appears with quotes and forward slashes ('/.../') and that the forward slashes in the URL then have to be escaped (\/). The language code is then matched with '[a-z][a-z]', but there are several other ways to do this and you may want something more liberal in case there are ever 3 letter codes, or caps. Equally you may need to do something tighter depending on what other URL schemes might appear.
I suspect in this instance it would be faster simply to use str_replace as follows:
$cleanedData = str_replace(array('www.example.com/en/', 'www.example.com/fr/'), '', $sourceData);
Finally i got a method my thanks to Purpletoucan
$newurl = preg_replace('/\/(en|esp|fr)\//', '/', $url);
it's working now i think!
I have this sitation:
..<img src="//http://www... OR ..<img src="/http://www... OR ..<img src="////http://www...
(/ - may be much)
How delete / before http?
Resultat always should be:
..<img src="http://www...
Thanks ;)
This should do the trick.
ltrim($url, "/");
This seems like a rather ad hoc solution. You might want to get to the bottom of the issue and eliminate it at source.
A regular expression along the lines of this should do the trick I think:
$string = preg_replace('/="\/+http:/', '="http:', $string);
Assuming that the url is defined in a variable within your PHP, ltrim() could be the answer
$url = ltrim($url,'/');
though you wouldn't be able to use this option if you had local url's (eg '/images/img.gif') without the 'http://'
You could do something like this (str_replace() because it is faster than a regular expression):
$markup = str_replace('//http://', 'http://', $markup);
Why do you need this? It might be better to eliminate the source of this problem.
I am trying to get the page or last directory name from a url
for example if the url is: http://www.example.com/dir/ i want it to return dir or if the passed url is http://www.example.com/page.php I want it to return page Notice I do not want the trailing slash or file extension.
I tried this:
$regex = "/.*\.(com|gov|org|net|mil|edu)/([a-z_\-]+).*/i";
$name = strtolower(preg_replace($regex,"$2",$url));
I ran this regex in PHP and it returned nothing. (however I tested the same regex in ActionScript and it worked!)
So what am I doing wrong here, how do I get what I want?
Thanks!!!
Don't use / as the regex delimiter if it also contains slashes. Try this:
$regex = "#^.*\.(com|gov|org|net|mil|edu)/([a-z_\-]+).*$#i";
You may try tho escape the "/" in the middle. That simply closes your regex. So this may work:
$regex = "/.*\.(com|gov|org|net|mil|edu)\/([a-z_\-]+).*/i";
You may also make the regex somewhat more general, but that's another problem.
You can use this
array_pop(explode('/', $url));
Then apply a simple regex to remove any file extension
Assuming you want to match the entire address after the domain portion:
$regex = "%://[^/]+/([^?#]+)%i";
The above assumes a URL of the format extension://domainpart/everythingelse.
Then again, it seems that the problem here isn't that your RegEx isn't powerful enough, just mistyped (closing delimiter in the middle of the string). I'll leave this up for posterity, but I strongly recommend you check out PHP's parse_url() method.
This should adequately deliver:
substr($s = basename($_SERVER['REQUEST_URI']), 0, strrpos($s,'.') ?: strlen($s))
But this is better:
preg_replace('/[#\.\?].*/','',basename($path));
Although, your example is short, so I cannot tell if you want to preserve the entire path or just the last element of it. The preceding example will only preserve the last piece, but this should save the whole path while being generic enough to work with just about anything that can be thrown at you:
preg_replace('~(?:/$|[#\.\?].*)~','',substr(parse_url($path, PHP_URL_PATH),1));
As much as I personally love using regular expressions, more 'crude' (for want of a better word) string functions might be a good alternative for you. The snippet below uses sscanf to parse the path part of the URL for the first bunch of letters.
$url = "http://www.example.com/page.php";
$path = parse_url($url, PHP_URL_PATH);
sscanf($path, '/%[a-z]', $part);
// $part = "page";
This expression:
(?<=^[^:]+://[^.]+(?:\.[^.]+)*/)[^/]*(?=\.[^.]+$|/$)
Gives the following results:
http://www.example.com/dir/ dir
http://www.example.com/foo/dir/ dir
http://www.example.com/page.php page
http://www.example.com/foo/page.php page
Apologies in advance if this is not valid PHP regex - I tested it using RegexBuddy.
Save yourself the regular expression and make PHP's other functions feel more loved.
$url = "http://www.example.com/page.php";
$filename = pathinfo(parse_url($url, PHP_URL_PATH), PATHINFO_FILENAME);
