hi i need to get the values of a var that after making it a var_dump($var) i get:
array(1) {
["docs"]=> array(3) {
[0]=> array(1) {
["imgurl"]=> string(68) "http://xxxxx.com/demos/grider/wp-content/uploads/2013/02/22.jpg" }
[1]=> array(1) {
["imgurl"]=> string(68) "http://xxxxx.com/demos/grider/wp-content/uploads/2013/02/33.jpg" }
[2]=> array(1) {
["imgurl"]=> string(68) "http://xxxxx.com/demos/grider/wp-content/uploads/2013/02/22.jpg" } } }
I need to foreach the 2 img url strings starting with http://
Any help would be appreciated.
Thank you
This should work:
foreach($var['docs'] as $sub) {
echo $sub['imgurl'];
}
foreach ($arr['docs'] AS $key => $link) {
echo $link['imgurl'].'<br />';
}

I have an array that consists of the keys:
$countries = ['EU', 'UK', 'Asia'];
Another array that consists of further elements based on those keys:
$countries_array=['UK'=>['London', 'Birmingham', 'Manchester'], 'EU'=> ['Germany','Netherlands'] , 'Asia'=> ['Pakistan','Bangladesh','China']];
$mid_countries[];
I want to pass through all the elements, check if they are empty or not and then further create another array. I have written a code and it works fine. But it has foreach loops. Is there any way that I could optimize this code?
foreach ($countries as $each_country) {
if (!empty($countries_array["$each_country"][0])) {
foreach ($countries_array["$each_country"] as $value) {
$mid_countries[] = array("wildcard" => array("$each_country" => $value. "*"));
}
}
}
Expected result:
array(8) {
[0]=> array(1) { ["wildcard"]=> array(1) { ["EU"]=> string(8) "Germany*" } } [1]=> array(1) { ["wildcard"]=> array(1) { ["EU"]=> string(12) "Netherlands*"}}
[2]=> array(1) { ["wildcard"]=> array(1) { ["UK"]=> string(7) "London*" } } [3]=> array(1) { ["wildcard"]=> array(1) { ["UK"]=> string(11) "Birmingham*" } } [4]=> array(1) { ["wildcard"]=> array(1) { ["UK"]=> string(11) "Manchester*" } } [5]=> array(1) { ["wildcard"]=> array(1) { ["Asia"]=> string(9) "Pakistan*" } } [6]=> array(1) { ["wildcard"]=> array(1) { ["Asia"]=> string(11) "Bangladesh*"}}
[7]=> array(1) { ["wildcard"]=> array(1) { ["Asia"]=> string(6) "China*" } } }
I think you expected this (Code updated use its working in single loop)
foreach ($countries_array as $key=>$value) {
$tmp=implode('*#'.$key.'#',$value);
$tmp='#'.$key.'#'.$tmp."*";
$tmp=str_replace('#'.$key.'#',"\"}},{\"wildcard\":{\"".$key."\":\"",$tmp);
$result=$result.substr($tmp,3)."\"}}";
}
$result="[".ltrim($result,"\"}},")."]";
$result=json_decode($result,true);
print_r($result);
My goal is to get specific element/value from a multidimensional array and assign them in a URL in loop. I have already tried and was able to get elements in the array but this displays all elements. I only want to get specific, like nid and field_x values.
This is my link structure: http://localhost:8080/$nid/$field_x
Expected result:
http://localhost:8080/123/one
http://localhost:8080/789/three
This is my sample var_dump result
array(1) {
[0]=>
array(38) {
["nid"]=>
array(1) {
[0]=>
array(1) {
["value"]=>
int(123)
}
}
["vid"]=>
array(1) {
[0]=>
array(1) {
["value"]=>
int(456)
}
}
["field_x"]=>
array(1) {
[0]=>
array(4) {
["target_id"]=>
string(6) "One"
}
}
["field_y"]=>
array(1) {
[0]=>
array(4) {
["target_id"]=>
string(2) "Two"
}
}
}
[1]=>
array(38) {
["nid"]=>
array(1) {
[0]=>
array(1) {
["value"]=>
int(789)
}
}
["vid"]=>
array(1) {
[0]=>
array(1) {
["value"]=>
int(321)
}
}
["field_x"]=>
array(1) {
[0]=>
array(4) {
["target_id"]=>
string(6) "Three"
}
}
["field_y"]=>
array(1) {
[0]=>
array(4) {
["target_id"]=>
string(2) "Four"
}
}
}
}
You can use a foreach() and get the data using $values['nid'][0]['value'] or $values['field_x'][0]['target_id']:
foreach ($result as $values) {
$nid = $values['nid'][0]['value'];
$field_x = $values['field_x'][0]['target_id'];
echo "http://localhost:8080/$nid/$field_x" ;
}
Will outputs:
http://localhost:8080/123/One
http://localhost:8080/789/Three
You probably want to do something else than an echo, so you can create a new array:
$urls = [];
foreach ($result as $values) {
$nid = $values['nid'][0]['value'];
$field_x = $values['field_x'][0]['target_id'];
$urls[] = "http://localhost:8080/$nid/$field_x" ;
}
print_r($urls);
I am calling a REST Api to get data using curl in php. It gives me the list of data/contents in the api in Array php format.
I was able to get single element value using $resultArray[0]['nid'][0]['value'];. But my goal is to get elements in all contents in the api.
Say I want to get the following elements in the nested arrays.
$resultArray[0]['nid'][0]['value'];
$resultArray[0]['vid'][0]['value'];
$resultArray[0]['cid'][0]['value'];
And use these values in a loop too.
I am trying to search how I can do it loop, and if anyone can provide sample code, that would be appreciated.
Update:
This is the sample result of var_dump:
array(1) {
[0]=>
array(38) {
["nid"]=>
array(1) {
[0]=>
array(1) {
["value"]=>
int(1)
}
}
["vid"]=>
array(1) {
[0]=>
array(1) {
["value"]=>
int(2)
}
}
["cid"]=>
array(1) {
[0]=>
array(1) {
["value"]=>
int(3)
}
}
["field"]=>
array(1) {
[0]=>
array(4) {
["target_id"]=>
int(4)
}
}
}
[1]=>
array(38) {
["nid"]=>
array(1) {
[0]=>
array(1) {
["value"]=>
int(11)
}
}
["vid"]=>
array(1) {
[0]=>
array(1) {
["value"]=>
int(22)
}
}
["cid"]=>
array(1) {
[0]=>
array(1) {
["value"]=>
int(33)
}
}
["field"]=>
array(1) {
[0]=>
array(4) {
["target_id"]=>
int(44)
}
}
}
[2]=>
array(38) {
["nid"]=>
array(1) {
[0]=>
array(1) {
["value"]=>
int(111)
}
}
["vid"]=>
array(1) {
[0]=>
array(1) {
["value"]=>
int(222)
}
}
["cid"]=>
array(1) {
[0]=>
array(1) {
["value"]=>
int(333)
}
}
["field"]=>
array(1) {
[0]=>
array(4) {
["target_id"]=>
int(444)
}
}
}
}
And I want to use these elements values in a loop.
Say my expected result is.
Test1 = "1", "2", "3"
Test2 = "11", "22", "33"
Test3 = "111", "222", "333"
These equivalent numbers should be comming from the element nid, vid, cid.
I dont just want to assign/echo these values in the result as I have array[100s] in one api call.
Since your array is a multidimensional array, you need to have nested foreach loops:
$test = 1;
foreach ($resultArray as $items) {
// Echo the current test number
echo "Test{$test} = ";
$values = [];
foreach ($items as $item) {
// Get the correct value.
if (array_key_exists('value', $item[0])) {
$values[] = $item[0]['value'];
continue;
}
if (array_key_exists('target_id', $item[0])) {
$values[] = $item[0]['target_id'];
continue;
}
}
echo '"' . implode('", "', $values) . '"' . "\n";
$test++;
}

I have array $result
array(2) {
["Smiley TV"]=>
array(2) {
["Speed"]=>
array(2) {
[0]=>
string(4) "9510"
[1]=>
string(5) "33775"
}
["Turbo"]=>
array(2) {
[0]=>
string(4) "2427"
[1]=>
string(5) "19696"
}
}
["Victory Media"]=>
array(1) {
["Speed"]=>
array(2) {
[0]=>
string(4) "4144"
[1]=>
string(5) "80445"
}
}
}
How with foreach i can get values. For example in the "Smyley TV" how i can result "Speed".
Also please write how i can get all data one by one. Thanks
You can fetch this way
foreach ($arrays as $array) {
echo $array['smyley TV'];
}
I have a fairly big array that I source from Facebook:
array(25) {
[0]=>
array(14) {
["id"]=>
string(31) "245226895508982_651884328176568"
["from"]=>
array(2) {
["name"]=>
string(16) "Madeleine Björs"
["id"]=>
string(15) "100002249777453"
}
["to"]=>
array(1) {
["data"]=>
array(1) {
[0]=>
array(2) {
["name"]=>
string(31) "Wohnung/WG in München gesucht!"
["id"]=>
string(15) "245226895508982"
}
}
}
Now what I want to do is go through the array and save ID, name and various other information from that array into a mysql database. However, to understand how to target specific information I tried to echo the data first.
$data = json_decode(file_get_contents('https://graph.facebook.com/'), true);
foreach($data as $item) {
echo $item['id'];
echo '<pre>'; var_dump($item);
}
This PHP code is based on various posts on Stackoverflow, however, the code returns nothing. May you please help me to target the arrays appropriately? You may check the enire array here: http://faculty-fight.de/milliondollaridea/facebook_session.php
Cheers!
foreach($array as $key=>$subArray)
{
foreach($subArray as $subKey=>subSubArray)
{
if(is_array($subSubArray))
{
foreach($subSubArray as $subSubKey=>$value)
{
if(is_array($value))
{
foreach($value as $valueKey=>$subValue)
{
/* your code /*
}
}
}
}
}
you can check for id values for example for 1st loop (if($subKey == "to")).
