I am using Solr and have the following query which works fine from my browser:
http://www.someipaddress.com:8983/solr/select?q=*&fq=shopid:40&start=0&rows=18&fq=manufacturer:"Bausch+%26+Lomb"
In part of the return xml I see:
<str>manufacturer:"Bausch & Lomb"</str>
However when I try and get the above url using simplexml_load_file like this:
$xml = simplexml_load_file("http://127.0.0.1:8983/solr/select?q=*&fq=shopid:40&start=0&rows=18&fq=manufacturer:\"Bausch+%26+Lomb\"");
I get no results because Solr is being passed the manufacturer string that looks like this (from print_r):
[str] => Array ( [0] => shopid:40 [1] => manufacturer:"Bausch+%26+Lomb" )
So when I am doing the query through the browser I pass in %26 but it deals with it correctly in the query. But when I use simplexml_load_file it remains as %26 and so the query fails.
Try:
simplexml_load_file(rawurlencode('http://127.0.0.1:8983/solr/select?q=*&fq=shopid:40&start=0&rows=18&fq=manufacturer:"Bausch' .urlencode('&'). 'Lomb"'))
See note on file parameter: http://php.net/manual/en/function.simplexml-load-file.php
Didn't work:
$url = 'http://127.0.0.1:8983/solr/select?q=*&fq=shopid:40&start=0&rows=18';
$url .= '&fq=manufacturer:"Bausch' .urlencode('&'). 'Lomb"';
simplexml_load_file(rawurlencode($url));
Manufacturer part of query came out as: "Bausch&Lomb";
Didn't work:
simplexml_load_file(rawurlencode('http://127.0.0.1:8983/solr/select?q=*&fq=shopid:40&start=0&rows=18&fq=manufacturer:"Bausch ' .urlencode('&'). ' Lomb"'))
Adding spaces next to the words Bausch and Lomb produced simplexml_load file error.
Worked:
simplexml_load_file(rawurlencode('http://127.0.0.1:8983/solr/select?q=*&fq=shopid:40&start=0&rows=18&fq=manufacturer:"Bausch+' .urlencode('&'). '+Lomb"'))
Swapping spaces for + works!
This is how I ended up doing it dynamically.
$manufacturer = urlencode("Bausch & Lomb");
$manufacturer_insert = "&fq=manufacturer:\"$manufacturer\"";
$xml = simplexml_load_file(rawurlencode("http://127.0.0.1:8983/solr/select?q=$shopid_insert$start_insert$rows_insert$sort_insert$manufacturer_insert"));
That works for manufacturers with an ampersand in their name.
It is important to note that if you were passing values with spaces they will now need to be urlencoded before being added. For example:
Before I could just use this for my sort insert:
$sort_insert = "&sort=price desc";
Now I need to urlencode just "price desc". When I tried to urlencode the whole sort_insert string the simplexml query would fail.
After (works):
$sort = urlencode("price desc");
$sort_insert = "&sort=$sort";
Thanks again... Back to the project!

The question seems quite simple, but I've tried everything that I've read and nothing worked
I have this example url: localhost/test/{"user":"test","password":"test"} so, that json is part of the url how can I add it? I tried the following things
$arrayVariable = array (
"Usuario" => "user",
"Clave" => "test"
);
$res = json_encode($arrayVariable);
but the answer of $res is the following
"{\"Usuario\":\"user\",\"Clave\":\"test\"}"
I've tried str_replace to remove backslashed but it didn't work, I tried the following two functions
$res = str_replace("\\","",$res)
$res = str_replace("\\\\","",$res)
but it didn't work because seems the backslash is part of the " quote
Edit: I can't change the url because is an external API so nothing I can do that way
You could use the urlencode() function.
$arrayVariable = array (
"Usuario" => "user",
"Clave" => "test"
);
$res = urlencode(json_encode($arrayVariable));
But i think you should re-think your logic since this is a very unusual thing to do.
I have a page working as I need it to, with the last /arist-name/ parsing into the correct variable, but the client is adding /artist-name/?google-tracking=1234fad to their links, which is breaking it.
http://www.odonwagnergallery.com/artist/pierre-coupey/ WORKS
http://www.odonwagnergallery.com/artist/pierre-coupey/?mc_cid=b7e918fce5&mc_eid=[UNIQID] DOES NOT WORK
$expl = explode("/",$_SERVER["REQUEST_URI"]);
$ArtistURL = $expl[count($expl)-1];
$ArtistURL = preg_replace('/[^a-z,-.]/', '', $ArtistURL);
Please help, I have been searching for a solution. Thanks so much!
PHP has a function called parse_url which should clean up the request uri for you before you try to use it.
parse_url
Parse a URL and return its components
http://php.net/parse_url
Example:
// This
$url_array = parse_url('/artist/pierre-coupey/?mc_cid=b7e918fce5&mc_eid=[UNIQID]');
print_r($url_array);
// Outputs this
Array
(
[path] => /artist/pierre-coupey/
[query] => mc_cid=b7e918fce5&mc_eid=[UNIQID]
)
Here is a demo: https://eval.in/873699
Then you can use the path piece to perform your existing logic.
If all your URLs are http://DOMAIN/artist/SOMEARTIST/
you could do:
$ArtistURL = preg_replace('/.*\/artist\/(.*)\/.*/','$1',"http://www.odonwagnergallery.com/artist/pierre-coupey/oij");
It would work in this context. Specify other possible scenarios if there are others. But #neuromatter answer is more generic, +1.
if you simply want to remove any and all query parameters, this single line would suffice:
$url=explode("?",$url)[0];
this would turn
http://www.odonwagnergallery.com/artist/pierre-coupey/?mc_cid=b7e918fce5&mc_eid=[UNIQID]&anything_else=whatever
into
http://www.odonwagnergallery.com/artist/pierre-coupey/
but if you want to specifically remove any mc_cid and mc_eid parameters, but otherwise keep the url intact:
$url=explode("?",$url);
if(count($url)===2){
parse_str($url[1],$tmp);
unset($tmp['mc_cid']);
unset($tmp['mc_eid']);
$url=$url[0].(empty($tmp)? '':('?'.http_build_query($tmp)));
}else if(count($url)===1){
$url=$url[0];
}else{
throw new \LogicException('malformed url!');
}
this would turn
http://www.odonwagnergallery.com/artist/pierre-coupey/?mc_cid=b7e918fce5&mc_eid=[UNIQID]&anything_else=whatever
into
http://www.odonwagnergallery.com/artist/pierre-coupey/?anything_else=whatever
may not have explained this properly but here we go.
I have a URL that looks like http://www.test.co.uk/?page=2&area[]=thing&area[]=thing2
Multiple "area"s can be added or removed from the URL via links on the site. on each addition of n "area" I wanted to remove the "page" part of the URL. so it can be reset to page1. I used parse_url to take that bit out.
Then I built an http query so it could generate the URL properly without "page"
this resulted in "area%5B0%5D=" "area%5B1%5D=" instead of "area[]="
When I use urldecode, now it shows "area[0]=" and "area[1]="
I need it to be "[]" because when using a link to remove an area, it checks for the "[]=" - when it's [0] it doesn't recognise it. How do I keep it as "[]="?
See code below.
$currentURL = currentURL();
$parts = parse_url($currentURL);
parse_str($parts['query'], $query);
unset($query['page']);
$currenturlfinal = http_build_query($query);
urldecode($currenturlfinal);
$currentURL = "?" . urldecode($currenturlfinal);
This is what I've done so far - it fixes the visual part in the URL - however I don't think I've solved anything as I've realised that what represents 'area' and 'thing' is not recognised as $key or $val as a result of what I think is parsing or reencoding the url in accordance with the code below. So I still can't remove 'areas' using the links
$currentURL_with_QS2 = currentURL();
$parts = parse_url($currentURL_with_QS2);
parse_str($parts['query'], $query);
unset($query['page']);
$currenturlfinal = http_build_query($query);
$currenturlfinal = preg_replace('/%5B[0-9]+%5D/simU', '[]', $currenturlfinal);
urldecode($currenturlfinal);
$currentURL_with_QS = "?" . $currenturlfinal;
$numQueries = count(explode('&', $_SERVER['QUERY_STRING']));
$get = $_GET;
if (activeCat($val)) { // if this category is already set
$searchString = $key . '[]= ' . $val; // we build the query string to remove
I'm using Wordpress as well may I add - maybe there's a way to reset the pagination through Wordpress. of course even then - when I go to page 2 on any page it still changes the "[]" to "5b0%5d" etc....
EDIT: this is all part of a function that refers to $key (the area/category) and $val (name of area or category) which is echoed in the link itself
EDIT2: It works now!
I don't know why but I had to use the original code and make the adjustments I did before again and now it works exactly how I want it to! Yet I couldn't see any visible differences in both codes afterwards. Strange...
As far as I know, there is no built-in way to do this.
You could try with:
$currenturlfinal = http_build_query($query);
Where $query is querystring part w/o area parameters and then:
foreach ($areas as $area) {
$currenturlfinal .= '&area[]='.$area;
}
UPD:
you could try with:
$query = preg_replace('/%5B[0-9]+%5D/simU', '%5B%5D', $query);
just place it right after http_build_query call.
$tempmoviename = "Battleship";
$omdburl = "http://www.omdbapi.com/?t=" . $tempmoviename;
$imdb_json = file_get_contents($omdburl);
$imdb_info = json_decode($imdb_json,true);
print ($imdb_info[0]->runtime[0]);
I can't get it to print the runtime of the movie. I can get it to print the actual website but not the information I need from the website.
In addition to that if I remove true
json_decode($imdb_json,true);
I get this error.
Fatal error: Cannot use object of type stdClass as array
How do I write this so it grabs the data from an array correctly? I also need to swap spaces and dashes in titles like Black Sheep, Black_Sheep to Black%20Sheep?
Do like this... Since you are converting the JSON to array (by passing true in the json_decode()), You need to access it like an array.
<?php
$tempmoviename = "Battleship";
$omdburl = "http://www.omdbapi.com/?t=" . $tempmoviename;
$imdb_json = file_get_contents($omdburl);
$imdb_info = json_decode($imdb_json,true);
echo $imdb_info['Runtime']; //"prints" 131 min
I have this code converting a mysql query to json:
$sth = mysql_query('SELECT * FROM `staff` ORDER BY `id` DESC LIMIT 20') or die(mysql_error());
$rows = array();
while($r = mysql_fetch_array($sth)) {
$rows[] = $r;
}
print json_encode($rows);
Works great, but i have in my database, a url field, here is a sample json row:
{"0":"4","id":"4","1":"Noter 2","name":"Noter 2","2":null,"desc":null,"3":"http:\/\/images.apple.com\/webapps\/productivity\/images\/noter2_20091223182720-thumb.jpg","iconurl":"http:\/\/images.apple.com\/webapps\/productivity\/images\/noter2_20091223182720-thumb.jpg","4":"1262032317","date":"1262032317","5":"dBelement, LLC","company":"dBelement, LLC","6":"http:\/\/dbelement.com\/","companyurl":"http:\/\/dbelement.com\/","7":"http:\/\/noter2.dbelement.com","appurl":"http:\/\/noter2.dbelement.com"},
How can i get around this?
I suppose the "problem" is the presence of backslashed in the URLs ?
Like :
http:\/\/images.apple.com\/webapps\/productivity\/images\/noter2_20091223182720-thumb.jpg
Well, that's not a problem for Javascript : try to assign your JSON data to a Javascript object, and display one of those URL :
var data = {"0":"4","id":"4","1":"Noter 2","name":"Noter 2","2":null,"desc":null,"3":"http:\/\/images.apple.com\/webapps\/productivity\/images\/noter2_20091223182720-thumb.jpg","iconurl":"http:\/\/images.apple.com\/webapps\/productivity\/images\/noter2_20091223182720-thumb.jpg","4":"1262032317","date":"1262032317","5":"dBelement, LLC","company":"dBelement, LLC","6":"http:\/\/dbelement.com\/","companyurl":"http:\/\/dbelement.com\/","7":"http:\/\/noter2.dbelement.com","appurl":"http:\/\/noter2.dbelement.com"};
alert(data[3]);
The URL is displayed correctly :
http://images.apple.com/webapps/productivity/images/noter2_20091223182720-thumb.jpg
So, the backslashes are not a "problem" ;-)
And, in fact, if you take a look at the "string" section of json.org, you'll see that slashes have to be backslashed for your string to be valid.
I don't see a problem here. If you're wondering why the URLs look like this:
http:\/\/www.example.com\/
Instead of like this:
http://www.example.com/
It's because the / characters are being appropriately escaped. When you unserialize the JSON object in javascript, the URLs will look as they do in your database.
