how can output of inside foreach with serialize store in database? next: called of database?
please give me example.
foreach($upload_data as $file) {
echo serialize($file['file']);
}
output: s:54:"Chrysanthemum6.jpg";s:47:"/Desert6.jpg";
With respect
Something like this?
$result = array();
foreach ($upload_data as $file) {
$result[] = $file['file'];
}
var_dump(serialize($result));
store the serialize in a variable?
$result = '';
foreach($upload_data as $file) {
$result .= serialize($file['file'];
}
echo $result;

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.
I'm loading event listing as an JSON-File from an URL:
$file = file_get_contents('http://ecample.com/listing.php?');
$data = json_decode($file);
?>
The direct output looks like this (more values and mor lines):
[{"id":"1","name":"NAME_1","booking_url":"https://ecample.com/Event_ID65654","category_id":"195"},
{"id":"2","name":"NAME_2","booking_url":"https://ecample.com/Event_ID65654","category_id":"195"},
"id":"1","name":"NAME_1","booking_url":"https://ecample.com/Event_ID65654","category_id":"195"}]
I need to search for all entrys with the value "name":"NAME_1" and print out the value of "booking_url".
I tried different things like array_seach() etc. but did not work out.
Any help is appreciated!
try this
<?php
$file = file_get_contents('http://ecample.com/listing.php?');
$data = json_decode($file, true);
foreach ($data as $r)
{
if ($r['name'] == 'NAME_1')
{
echo $r['booking_url'];
}
}
?>
The other option is to access your data in object context, thus:
<?php
$file = file_get_contents('http://ecample.com/listing.php?');
$data = json_decode($file);
foreach ($data as $r)
{
if ($r->name == 'NAME_1')
{
echo $r->booking_url;
}
}
?>
Either one should work just as well.
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 .'='. $value. '<br/>';
}
I have this code:
foreach ($row as $result) {
if (empty($row[28])) {
$string28 = '';
} else {
$string28 = '<div class="add_img">
<h1>Connexion</h1>
<img src="images/' . $row[28] . '.jpeg">
</div>';
}
}
foreach ($row as $result) {
if (empty($row[30])) {
$string30 = '';
} else {
$string30 = '<div class="add_img">
<h1>Fixation</h1>
<img src="images/' . $row[30] . '.jpeg">
</div>';
}
}
foreach ($row as $result) {
if (empty($row[31])) {
$string31 = '';
} else {
$string31 = '<div class="add_img">
<h1>Schéma</h1>
<img src="images/' . $row[31] . '.jpeg">
</div>';
}
}
$applications = array($string28, $string30, $string31);
if (empty($applications)) {
$vide = "<h1>Pas D'Application Pour Ce Produit</h1>";
}
What I want to say here is: if all the variables are empty then show me this:
Pas D'Application Pour Ce Produit (Translated: No application for this product)
But When I use the print_r function it tells to me that the array has no data to deal with.
Please I need Help.
And Thanks to all in advanced
You are not accessing your rows correctly in your foreach loops. When using foreach($row as $result) you need to refer to the array element as $result, not row. If you need to identify a specify array key you can specify that by using foreach($row as $key => $result).
For example, in your first loop you should use this:
$string28 = ''; //Initialize your variable so can be used after the foreach loop exits
foreach ($row as $key => $result) {
if($key == 28 && empty($result[$key]) {
$string28 = '';
} else {
$string28 = '<div class="add_img"><h1>Connexion</h1><img src="images/'.$result[$key].'.jpeg">
}
}
Repeat for the other loops in your script.
EDIT
Yes, you can setup one foreach loop that will go through all your variables and create variables for you. Based on your question, if you don't have any apps an error message shows. What you may wish to do is simply set a flag based on that criteria. You could do do this like so:
$noApps = true;
$applications = array();
foreach($row as $key => $result) {
if(isset($result[$key]) && empty($result[$key])) {
$applications[$key] = '<div class="add_img"><h1>Connexion</h1><img src="images/'.$result[$key].'.jpeg'>;
$noApps = false;
}
}
if($noApps) {
echo "<h1>Pas D'Application Pour Ce Produit</h1>";
} else {
print_r($applications); //For viewing/debugging purposes
}
Your foreach loops is wrong. You are using the whole array instead of the elements as is used within a foreach loop.
You have used
foreach ($row as $result) {
//You are doing something with $row
}
Instead correct usage is
foreach ($row as $result) {
//Do something with $result
}
Hope it helps :)
Your design looks bad. You are essentially repeating the same functionality 3 times.
Your while loops don't work because you're using $row in them, instead of the $result variable.
The second point is, The $string28, $string30, $string31 are created as local variables within the if conditions you have written in the while loops. Once the control exits the "if" loops these variables are nothing. To solve this problem, try initializing these to empty data like$string28 ="" at the beginning point of your code.
However, I would recommend you to look at the structure of your code first.
I have got following array in php:
theArray('id':'123','akey':'a';
'id':'234','akey':'b';
'id':'567','akey':'c';)
I would like to dynamically add another key in a loop so that my array will look like:
theArray('id':'123','akey':'a', 'anotherkey':'1';
'id':'234','akey':'b'; 'anotherkey':'1';
'id':'567','akey':'c'; 'anotherkey':'1';)
The code I have written is the following:
foreach($theArray as $row)
{
$row['anotherkey'] = "1";
}
but it is not working. What am I doing wrong?
You're not actually storing your new value in $theArray, you're just assigning it to your temporary $row variable. What you want to do is this:
foreach($theArray as $key => $row) {
$theArray[$key]["anotherkey"] = "1";
}
Try with
foreach($theArray as &$row)
{
$row['anotherkey'] = "1";
}
foreach($theArray as $key => $row)
{
$theArray[$key]['anotherkey'] = "1";
}
is more robust
