It show
best%20engineering%20college%20in%20India
Here, I want to replace %20 with (-) from url and get result like
best-engineering-college-in-India
how can I fix this problem please help.
Thank you
1.you can use this php built in function.you just want to replace a piece of string by another.
$new_url = str_replace('%20', '-', $url);
for more information
http://fr2.php.net/str_replace
2.Use urlencode to encode. The decoding will happen automatically,
and if you want to remove total 20% then use this code.
$url = "one%20%26%20two";
$a = urldecode($url); // -> "one & two"
suppose your page when loading then create your url like this
$protocol = (!empty($_SERVER['HTTPS']) && $_SERVER['HTTPS'] !== 'off' || $_SERVER['SERVER_PORT'] == 443) ? "https://" : "http://";
$base_url = $protocol . $_SERVER["SERVER_NAME"];
then use it
urldecode($base_url)
if you want to use this in url then
echo '<a href="?mycgi?foo=', urlencode($userinput), '">';
for more information
http://www.php.net/manual/en/function.urldecode.php
You should use str_replace() here:
echo str_replace('%20', '-', $input); // best-engineering-college-in-India
Basically you want to decode the URL. You can decode it using
echo utf8_decode(urldecode($input));

I am going to make a URL checking system.
I have this URL
https://lasvegas.craigslist.org/mob/6169799901.html
Now I want to make this URL like this
https://lasvegas.craigslist.org/search/mob?query=6169799901
how can I do it using PHP?
Since I ended up (maybe?) solving it anyways, here's one method using URL/path parsing:
$url = 'https://lasvegas.craigslist.org/mob/6169799901.html';
$parsed = parse_url($url);
$basepath = pathinfo($parsed['path']);
echo $parsed['scheme'].
"://".
$parsed['host'].
"/search".
$basepath['dirname'].
"?query=".
$basepath['filename'];
Formatted for readability.
https://3v4l.org/E6Y54
Try this
$url = "https://lasvegas.craigslist.org/mob/6169799901.html";
$id = substr($url, strrpos($url, '/') + 1);
$id = str_replace(".html","",$id);
$result = "https://lasvegas.craigslist.org/search/mob?query=".$id;
echo $result;
I have this domain
https://test.com/?url=https://google.com/search?q=#ie7&rls=login.microsoft:en-US:IE-Address&ie=&oe=#
And this is the code:
<?php
//check if the url parameter exists
if(isset($_GET['url'])) $url=$_GET['url'];
else $url=FALSE;
?>
If I use this in the html
<?=(!$url) ? '' : $url ?>
I get an output that cuts off in special characters like # or & etc.. and becomes like this for example https://google.com/search?q=# I tried urlencode/decode but couldn't figure it out
if you need all after ?url=, you can try this:
$url = $_SERVER['REQUEST_URI'];
$url2 = substr($url, strpos($url, '?url')+5);
$url = substr($url, strpos($url, '?url'));
print($url); // url?=https://..etc
print($url2); // https://..etc
you want to output the full domain just after
https://test.com/?url=
to the end, and get https://google.com/search?q=#ie7&rls=login.microsoft:en-US:IE-Address&ie=&oe=# right?
So if this is fixed, you can do:
echo substr($url, 22);
This question already has answers here:
Get only filename from url in php without any variable values which exist in the url
(13 answers)
Closed 7 years ago.
I wanted to print the last characters after "/" in a url. but instead it is printing the whole url, I expected the output to be just "index.php" instead it is printing out the whole url.
How should i go about doing it right?
$data = $_SERVER['REQUEST_URI'];
$whatIWant = substr($data, strpos($data, "/") + 1);
echo $whatIWant;
You can see it here
You should get the actual link by
<?php
$actual_link = "http://$_SERVER[HTTP_HOST]$_SERVER[REQUEST_URI]";
$getpath=explode("/",$actual_link);
echo end($getpath);
?>
Short Explanation :
Step 1 : Get the url by
http://$_SERVER[HTTP_HOST]$_SERVER[REQUEST_URI]
Step 2 : Explode with slash
explode("/",$actual_link)
Step 3 : Get the last part
end($getpath);
Try this..
<?php
$data = "http://$_SERVER[HTTP_HOST]$_SERVER[REQUEST_URI]";
$whatIWant = explode("/",$data);
echo end($whatIWant);?>
You can also try it this way using strrchr :
$url = 'http://spiritofethiopia.com/test/test/test/index.php';
$str = substr(strrchr($url, '/'), 1);
echo $str;
strrchr — Find the last occurrence of a character in a string.
You can use preg_match whith a correct RegExp to capture the end of the URL.
<?php
$data = $_SERVER['REQUEST_URI'];
if(preg_match('#/([^/]*?)$#', $data, $matches) == 1) {
echo $matches[1];
}
else {
// Should not happen
/*
* Throw exception
*/
}
?>
Try strripos instead of strpos, it may works
<?php
$data = $_SERVER['REQUEST_URI'];
$whatIWant = substr($data, strripos($data, "/") + 1);
echo $whatIWant;
?>
Try This:
working solution,
<?php
$url = 'http://test/test/test/index.php';
$tokens = explode('/', $url);
echo $tokens[sizeof($tokens)-1];
?>
I'm trying to change a value in a string that's holding my current URL. I'm trying to get something like
http://myurl.com/test/begin.php?req=&srclang=english&destlang=english&service=MyMemory
to look like
http://myurl.com/test/end.php?req=&srclang=english&destlang=english&service=MyMemory
replacing begin.php for end.php.
I need the end.php to be stored in a variable so it can change, but begin.php can be a static string.
I tried this, but it didn't work:
$endURL = 'end.php';
$beginURL = 'begin.php';
$newURL = str_ireplace($beginURL,$endURL,$url);
EDIT:
Also, if I wanted to replace
http://myurl.com/begin.php?req=&srclang=english&destlang=english&service=MyMemory
with
http://newsite.com/end.php?req=&srclang=english&destlang=english&service=MyMemory
then how would I go about doing that?
Assuming that you want to replace the script filename of the url, you can use something like this :
<?php
$endURL = 'end.php';
$url ="http://myurl.com/test/begin.php?req=&srclang=english&destlang=english&service=MyMemory";
$pattern = '/(.+)\/([^?\/]+)\?(.+)/';
$replacement = '${1}/'.$endURL.'?${3}';
$newURL = preg_replace($pattern , $replacement, $url);
echo "url : $url <br>";
echo "newURL : $newURL <br>";
?>
How do you want them to get to end.php from beigin.php? Seems like you can just to a FORM submit to end.php and pass in the variables via POST or GET variables.
The only way to change what page (end.php, begin.php) a user is on is to link them to another page from that page, this requires a page refresh.
I recently made a PHP-file for this, it ended up looking like this:
$vars = $_SERVER["QUERY_STRING"];
$filename = $_SERVER["PHP_SELF"];
$filename = substr($filename, 4);
// for me substr removed 'abc/' in the beginning of the string, you can of course adjust this variable, this is the "end.php"-variable for you.
if (strlen($vars) > 0) $vars = '?' . $vars;
$resultURL = "http://somewhere.com" . $filename . $vars;
I use $_SERVER['QUERY_STRING'] to get the query sting.
A example would be a=123&b=456&c=789
How could I remove the b value from the query string to obtain a=123&c=789 where b can be any value of any length and is alpha numeric.
Any ideas appreciated, thanks.
A solution using url parsing:
parse_str($_SERVER['QUERY_STRING'], $result_array);
unset($result_array['b']);
$_SERVER['QUERY_STRING'] = http_build_query($result_array);
The value is going to be $_GET['b'].
How about:
str_replace('&b='.$_GET['b'], '', $_SERVER['QUERY_STRING']);
you can use this function:
function Remove_QS_Key($url, $key) {
$url = preg_replace('/(?:&|(\?))'.$key.'=[^&]*(?(1)&|)?/i', "$1", $url);
return $url;
}
to remove any key you want, e.g.
echo Remove_QS_Key("http://domain.com/?a=b&ref=dusername&c=d&e=f&g=h", "ref");
result
http://www.domain.com/?a=b&c=d&e=f&g=h
Try this:
$query_new = preg_replace('/(^|&)b=[^&]*/', '', $query);
All the answers look good, but it will be more flexible if you do:
// Make a copy of $_GET to keep the original data
$getCopy = $_GET;
unset($getCopy['b']); // or whatever var you want to take out
// This is your cleaned array
var_dump($getCopy);
// If you need the URL-encoded string, just use http_build_query()
$encodedString = http_build_query($getCopy);
You simply make a variable using $_GET and exclude b query string in build process:
$query_string_new = 'a=' . urlencode($_GET['a']) . '&c=' . urlencode($_GET['c']);
The $query_string_new should now contain a=123&c=789
Pear already has a class(Net_URL2) that handles URL parsing/building:
Install via Composer: https://packagist.org/packages/pear/net_url2
Install as include: https://github.com/pear/Net_URL2/blob/master/Net/URL2.php
Example code:
$url = new Net_URL2('http://www.example.com/?one=1');
$url->setQueryVariable('two', 2);
echo $url; // http://www.example.com/?one=1&two=2
Here is a function to replace a query parameter: (like example.com?a=1&b=2 -> example.com?a=5&b=2)
function replace_qs_key($key, $value) {
$current_url = (isset($_SERVER['HTTPS']) && $_SERVER['HTTPS'] === 'on' ? "https" : "http") .
"://$_SERVER[HTTP_HOST]$_SERVER[REQUEST_URI]";
$current_url_without_qs = strtok($current_url, '?');
parse_str($_SERVER['QUERY_STRING'], $query_params);
$query_params['page'] = $value;
$_SERVER['QUERY_STRING'] = http_build_query($query_params);
$new_url = $current_url_without_qs .'?'. $_SERVER['QUERY_STRING'];
return $new_url;
}
