I want to get request in a website like that
$id = "something";
$response = http_get("http://example.com?id=$id, array("timeout"=>1), $out);
I don't find how exactly I can use http_get
I've tried with file_get_contents, it is working like
$out = file_get_contents("http://www.example.com?id=something");
but I want it like that
$out = file_get_contents("http://www.example.com?id=$id");
this one is not working
The way I got it to work was using the code below.
$out = file_get_contents("http://www.example.com?id=".$id);
This will concatenate the $id variable contents onto the end of the url to request.

I've looked at every post on SO that remotely pertains to this and I just can't figure this out. This code is taken directly from another SO post and was marked as the correct working answer:
$query = $_GET;
// replace parameter(s)
$query['d'] = 'new_value';
// rebuild url
$query_result = http_build_query($query);
// new link
Link
Again, taken straight from another post. When I try this code, i change the $_GET to the actual URL that i want to alter. When the code gets to the $query['d'] part, it tells me I get an illegal string offset and the error is the index that's specified. So then I parse the URL, and then do parse_str($query, $output) which in turn allows me to do $output['d'] and THEN I can set a new value to that variable. If I echo it out, it's fine.
But then I get to the http_build_query line, and it tells me that it's expecting an array or object and I can't build the new URL. Here is my code:
$link = parse_url('https://www.google.com/search?source=hp&ei=85GhW6CNHoSqsgXnzoD4Ag&q=coding+tutorial&btnK=Google+Search&oq=coding+tutorial', PHP_URL_QUERY);
parse_str($link, $output);
$output['oq'] = 'new value';
$query_result = http_build_query($link);
echo $query_result;
This code yields that the http_build_query function wants an array or object...i guess i'm not giving it that in some way? What do I need to do to get this to work?
If you want to rebuild the full URL after modifying the query parameters, you could do this:
$url = 'https://www.google.com/search?source=hp&ei=85GhW6CNHoSqsgXnzoD4Ag&q=coding+tutorial&btnK=Google+Search&oq=coding+tutorial';
$link = parse_url($url, PHP_URL_QUERY);
parse_str($link, $output);
$output['oq'] = 'new value';
echo substr($url, 0, strpos($url, '?') + 1) . http_build_query($output);
Output:
https://www.google.com/search?source=hp&ei=85GhW6CNHoSqsgXnzoD4Ag&q=coding+tutorial&btnK=Google+Search&oq=new+value
I'm looking to get some input on how to make modular code that performs a PHP parse_ini_file and then uses the returned values to run JSON decodes.
I have a BACnet API that returns a JSON structure for BACnet points in an automation system. I wrote the following code to decode the JSON data to return just the "present-value" field and then I display the value on a webpage.
<?php
$url = "http://hostname.lcl:47800/api/v1/bacnet/devices/10100/objects/0.0";
$json = file_get_contents($url);
$json_data = json_decode($json, true);
echo "<b>Room temperature</b>: ". $json_data["present-value"]. " DEG F";
;?>
This works well but I want to make this code modular so it can be used for many other points.
I created an INI file with a list of other points and the URL that contains the JSON data from the API.
## BACnet Configuration File
# BACnet Object URLs from WACNET Browser API
[bacnet]
SEA_RMT = http://hostname.lcl:47800/api/v1/bacnet/devices/10100/objects/0.0
SEA_SRV_SEA_SV1_01_EXHT = http://hostname.lcl:47800/api/v1/bacnet/devices/10100/objects/0.3
SEA_SRV_SEA_SV1_02_EXHT = http://hostname.lcl:47800/api/v1/bacnet/devices/10100/objects/0.4
SEA_SRV_SEA_SV1_03_EXHT = http://hostname.lcl:47800/api/v1/bacnet/devices/10100/objects/0.5
What I'd like to do is use the INI file to get the present value of each point in the list and then create a variable that is the name of the point and set it equal to the "present-value" field. Then I can reference the point using the PHP variable on the HTML page like this:
<?php echo "$SEA_SRV_SEA_SV1_01_EXHT";?>
I started with the code below but it doesn't work.
<?php
// Parse the settings file
$bacnetini = parse_ini_file('/var/www/config/bacnet.ini');
// Parse the keys to variables and add data
foreach ($bacnetini as $key => $value) {
$url = $value;
$json = file_get_contents($url);
$json_data = json_decode($json, true);
$$key = $json_data;
}
?>
I'd love to get some other opinions on the best way to accomplish this since I don't really know where to go from here.
I've looked through these other Stack Overflow questions but I don't know how to get the pieces to all fit together.
Parsing a config file in php to variables
Get JSON object from URL
Why not try something like this instead? This will allow you to create other sections in your INI file that won't affect your script.
<?php
$bacnetini = parse_ini_file('/var/www/config/bacnet.ini', true);
$data = array();
foreach ($bacnetini['bacnet'] as $key => $url) {
$data[$key] = json_decode(file_get_contents($url), true);
}
var_dump($data['SEA_SRV_SEA_SV1_01_EXHT']);
?>
Im new to php and tried to get a json object from the twitch API to retrieve one of its values and output it. i.e
i need to get the information from this link: https://api.twitch.tv/kraken/users/USERNAME/follows/channels/CHANNELSNAME
plus i need to to something so i can modify the urls USERNAME and CHANNELSUSERNAME. I want it to be a api to call for howlong user XY is following channelXY and this will be called using nightbots $customapi function.
the date i need from the json is "created_at"
Since we were able to clear out the errorsheres the final PHP file that works if anyone encounters similiar errors:
<?php
$url = "https://api.twitch.tv/kraken/users/" . $_GET['username'] . "/follows/channels/" . $_GET['channel'];
$result = file_get_contents($url);
$result = json_decode($result, true);
echo $result["created_at"];
?>
You have a typo in your code on the first line and you're not storing the result of your json_decode anywhere.
<?php
$url = "https://api.twitch.tv/kraken/users/" . $_GET['username'] . "/follows/channels/" . $_GET['channel'];
$result = file_get_contents($url);
$result = json_decode($result, true);
echo $result["created_at"];
You have to call the page this way page.php?username=yeroise&channel=ceratia in order to output the created_at value for this user and this channel.
In your code you're using 2 different ways to get the content of the page and you only need one (either file_get_contents or using CURL), I chose file_get_contents here as the other method adds complexity for no reason in this case.
I am trying to set up a small script that can play youtube videos but thats kinda besides the point.
I have $ytlink which equals www.youtube.com/watch?v=3WAOxKOmR90
But I want to make it become www.youtube.com/embed/3WAOxKOmR90
Currently I have tried
$result = str_replace('https://youtube.com/watch?v=', "https://youtube.com/watch?v=", $ytlink);
But this returns it as standard
I have also tried
preg_replace('/https://youtube.com/watch?v=/, '/https://youtube.com/embed/', $ytlink);
but both of these dont work.
Instead of using ugly regexes, I recommend using parse_url() with parse_str(). This allows you to be flexible in the event that you want to change something or if Youtube decides to change their URL slightly.
$url = 'https://www.youtube.com/watch?v=3WAOxKOmR90';
// Parse the URL into parts
$parsed_url = parse_url($url);
// Get the whole query string
$query = $parsed_url['query'];
// Parse the query string into parts
parse_str($query, $params);
// Get the parameter you want
$v = $params['v'];
// Now re-build the URL how you want
echo $parsed_url['scheme'].'://'.$parsed_url['host'].'/embed/'.$v;
// Outputs: https://www.youtube.com/embed/3WAOxKOmR90
This works:
$ytlink = 'www.youtube.com/watch?v=3WAOxKOmR90';
$result = str_replace('watch?v=', 'embed/', $ytlink);
echo $result;
$url = 'www.youtube.com/watch?v=3WAOxKOmR90';
echo preg_replace('/.*?v=(\w+)/i', 'www.youtube.com/embed/$1', $url);
i'm doing api calls from php backend like this:
$term = "AT&T Park";
$q = '"'. urlencode($term) .'"';
$url = "http://search.twitter.com/search.json?q={$q}&rpp=100";
$api_call = file_get_contents($url);
it's not returning anything, but same api call working just fine on my terminal.
here is a little screencast showing what's going on:
http://screencast.com/t/RnZsrwfGcc2q
any ideas?
you need to urlencode the quotes too.
change your code to the following
$term = '"AT&T Park"';
$q = urlencode($term);
$url = "http://search.twitter.com/search.json?q={$q}&rpp=100";
$api_call = file_get_contents($url);
and it should work
You can use cURL in your PHP file. This may work.
