I am using a URL to fetch data stored/shown within URL. I get all the value of variable using $_REQUEST['v_name'] but if there is a array in URL how can i retrieve that value.
For Example:
WWW.example.com/rooms?&hid=213421&type=E
I got the value hid and type using
$hid=$_REQUEST['hid'];
but in URL like:
WWW.example.com/rooms?&rooms=2&rooms[0].adults=2&rooms[0].children=0&rooms[1].adults=2&rooms[1].children=0
how can i retrieve value of adults and children in each room.
please help.
Thanks in Advance
You could also try something like this, since most of your original $_REQUEST isn't really an array (because of the .s in between each key/value pair):
<?php
$original_string = rawurldecode($_SERVER["QUERY_STRING"]);
$original_string_split = preg_split('/&/', $original_string);
$rooms = array();
foreach ($original_string_split as $split_one) {
$splits_two[] = preg_split('/\./', $split_one);
}
foreach ($splits_two as $split_two) {
if (isset($split_two[0]) && isset($split_two[1])) {
$split_three = preg_split('/=/', $split_two[1]);
if (isset($split_three[0]) && isset($split_three[1])) {
$rooms[$split_two[0]][$split_three[0]] = $split_three[1];
}
}
}
// Print the output if you want:
print '<pre>' . print_r($rooms, 1) . '</pre>';
$valuse = $_GET;
foreach ($valuse as $key=>$value)
{
echo $key .'='. $value. '<br/>';
}

I have this json file: and I would like to get all the title so my code is: var_dump($json['results'][0]['title']); but it getting just one title, I know I need to do a foreach but I don't know how :( so if you could help me that will be great ! Thanks
Your data is coming back as an array with item's inside of it. This mean's you'll need to loop through this JSON and print each item;
foreach($json['results'] as $movie) {
echo $movie['title'] . "<br />";
}
You will want to loop through all of the JSON results objects and echo or store the 'title' value;
foreach ($json['results'] as $object) {
//Option 1
echo $object['title'];
//Option 2
array_push($titles, $object['title'];
}
Assuming that the variable $json contains your data, I see two equivalent options in order to iterate trough the array
Using for
for($index = 0; $index < count($json['results']); $index++) {
echo $json['results'][$index]['title'] . "\n";
}
Using foreach
foreach($json['results'] as $movie) {
echo $movie['title'] . "\n";
}
So I would like to create just one loop to parse the json data i have. I can successfully parse it in 2 foreach loops however when trying to combine in one loop using $key => $value the $key returns nothing when called. How can I successfully take the 2 foreach loops I have here and combine them into one?
$contents = file_get_contents($url);
$results = json_decode($contents, true);
$jsonList = $results['genres'];
foreach($jsonList as $key) {
$GenreID = $key['id'].'<br>';
echo $GenreID;
}
foreach($jsonList as $key => $value) {
$GenreName = $value['name'].'<br><br>';
echo $GenreName;
}
The json data is as follows:
{"genres":[{"id":28,"name":"Action"},{"id":12,"name":"Adventure"},{"id":16,"name":"Animation"},{"id":35,"name":"Comedy"},{"id":80,"name":"Crime"},{"id":99,"name":"Documentary"},{"id":18,"name":"Drama"},{"id":10751,"name":"Family"},{"id":14,"name":"Fantasy"},{"id":36,"name":"History"},{"id":27,"name":"Horror"},{"id":10402,"name":"Music"},{"id":9648,"name":"Mystery"},{"id":10749,"name":"Romance"},{"id":878,"name":"Science Fiction"},{"id":10770,"name":"TV Movie"},{"id":53,"name":"Thriller"},{"id":10752,"name":"War"},{"id":37,"name":"Western"}]}
You can still use $key as an index when also extracting the $value.
However note that you shouldn't be assigning the line breaks to your variables, and should instead consider them part of the view by echoing them out independently:
$contents = file_get_contents($url);
$results = json_decode($contents, true);
$jsonList = $results['genres'];
foreach($jsonList as $key => $value) {
$GenreID = $key['id']; // Depending on structure, you may need $value['id'];
$GenreName = $value['name'];
echo $GenreID . '<br>';
echo $GenreName . '<br><br>';
}
Your single loop below here.
foreach($jsonList as $key)
{
$GenreID = $key['id'].'<br>';
echo $GenreID;
$GenreName = $value['name'].'<br><br>';
echo $GenreName;
}
$key is a assosative array.Therefore it had some index.So you can use this index in single loop.
It seems you get confused over your data structure. Seeing the json, the resulting "$jsonlist" supposed to contain array with id and value as keys.
You can iterate over it and extract the the appropriate key.
Myabe something like this:
foreach($jsonlist as $value) {
echo "id: " . $value['id'] . "\n";
echo "name: " . $value['name'] . "\n";
}
extra bonus, if you want to create 1 level array from your json based on id with the name you could try array reduce using anon function like this:
$jsonlist = array_reduce($jsonlist, function($result, $item){
$result[$item['id']] = $item['name'];
return $result;
}, []);
extra neat for transformation of static structure data.
So, I wanna select item per item from this array ["A185","A740","A540"]
Like for example I wanna select
$cie[0] = A185 or A740
with something like $cie[0] = A185
This is my code so far, since I fetch that code from a row in a MySQL table.
while ($row = pg_fetch_array($resul)) {
$cie10 = array($row["cie"]);
}
$cie = ["A185","A740"];
$values = array_count_values($cie);
$top = array_slice($values, 0, 1);
print_r($top);
What I get:
Array ( [["A185","A740","A540"]] => 1 )
It just won't work.
I'm Sure you are looking to display the data that is in the array variable
$var = ["A185","A740","A540"]; // Asume as you stored the values in the array called var
foreach($var as $x){
print_r($x);
echo "<br/>";
}
EDIT: Highlighted the code
If i understand your problem. You are looking for this:-
$Fullarray = ["A185","A740","A540"];
$cie = array_slice($Fullarray,0,2);
foreach ($cie as $name) {
$d[] = '"' . $name . '"';
}
$implodekeys = "[".implode(',',$d)."]";
$newarray[$implodekeys] =1;
echo "<pre>"; print_r($newarray);
Hope it helps!
I used http build query to send data from URL
The Url is in the following format :
http://www.abc.in/xyz/Tak-Wadi?0%5Bmerchant_location_id%5D=1&1%5Bmerchant_location_id%5D=2
Now How to get data ie. merchant_location_id 1 & 2.
This might help you.
echo $id1 = $_GET[0]['merchant_location_id'];
echo $id2 = $_GET[1]['merchant_location_id'];
if you do the following:
$url = urldecode("http://www.abc.in/xyz/Tak-Wadi?0%5Bmerchant_location_id%5D=1&1%5Bmerchant_location_id%5D=2");
echo $url;
That will clear it up a bit:
http://www.abc.in/xyz/Tak-Wadi?0[merchant_location_id]=1&1[merchant_location_id]=2
Now, this url let's you know that you've got two arrays each containing one key (merchant_location_id)
$_GET[0]
$_GET[1]
Now that we know this it's easy to retrieve the data.
echo $_GET[0]['merchant_location_id'];
echo $_GET[1]['merchant_location_id'];
That should be all there is to it.
$queryString = array();
foreach ($_GET as $key => $value) {
$queryString[] = $key . '=' . $value;
}
$queryString = implode('&', $queryString);
For further assistance you can get reference from this weblink.
I need to pass a variable to a foreach loop from a mySQL result.
So I have this code:
$GetClaim = "SELECT * FROM cR_Claimants WHERE memberID = '".$memberID."' AND ParentSubmission ='".$refNumb."'";
$resultGetClaim=mysql_query($GetClaim) or die("Error select claimants: ".mysql_error());
while($rowGetClaim = mysql_fetch_array($resultGetClaim)) {
$name = $rowGetClaim['Name'];
$city = $rowGetClaim['city'];
$region = $rowGetClaim['region'];
}
Now I need to pass the variable to the foreach
foreach($name as $k=>$v) {
echo $city;
echo $region;
etc..
}
The above code does not work. I think I cannot pass a variable from a mySQL loop. The problem is also tat every row I get from the database should be related to the specific $name. So obvioiusly one $name will have its own $city etc..
How do I achieve this?
Please help
You are not retrieving an array with all returned records, you are retrieving an array which contains a single record.
To get the next name (the next record), you must make another call to mysql_fetch_array.
The code you present does that implicitly by assigning $rowGetClaim within a while conditional. A failed mysql_fetch_array call would return false, which would exit the while loop.
There is absolutely no need to use the for each as you presented. Just place the echo right after the assignment (e.g.
$region = $rowGetClaim['region'];
echo $region
Either out put directly fromt eh loop or build an array and then loop through it.
while($rowGetClaim = mysql_fetch_array($resultGetClaim)) {
echo $rowGetClaim['Name'];
echo $rowGetClaim['city'];
echo $rowGetClaim['region'];
}
OR
while($rowGetClaim = mysql_fetch_array($resultGetClaim)) {
foreach($rowGetClaim as $k => $v{
echo $v;
}
}
OR
$names = array();
while($rowGetClaim = mysql_fetch_array($resultGetClaim)) {
$names[] = $rowGetClaim;
}
foreach($names as $data){
foreach($data as $k => $v) {
echo $v;
}
}
