This is a large data structure with many embedded arrays. Each array has n elements, in this example, 37. I am trying to access the 'content' element in the 1st and 3rd position, of each of the arrays.
array[1]->percentage->content
and
array[3]->grade->content
$tdata is the variable that contains the data structure. I have tried looping over like this:
$i=0;
foreach($tdata as $td){
if($td[$i] == 1 OR $td[$i] == 3){
var_dump($td[$i])
}
$i++;
}
This is the data structure.

I need to show a page with links from my database
array (size=5)
0 =>

array (size=3)
'id' => string '7' (length=1)

like this
A
apple <-- it's a link name with url
N
nokia
S
samsung
sony
X
xaomi
in alphabet order with letter (capital)
I know how to do it with ordinary array (just names)
$result = array();
$previous = null;
$i = 0;
foreach ($this->model as $value) {
$firstLetter = substr($value, 0, 1);
if ($previous !== $firstLetter) {
$result[$i] = mb_convert_case($firstLetter, MB_CASE_UPPER, "UTF-
8");
$i++;
}
$result[$i] = $value;
$previous = $firstLetter;
$i++;
}
but i don't understand how can i do it with multidimensional array.
i can sort firstly by "name" attribute, but how to get a first letter to put in new array
[
"A" = > array ('name' => apple,'url' => 'http://...'),
"S" => array ('name' => samsung, 'url' => 'http://...')
]
to show it with foreach operator
I use this function for getting firstletter
$result = array();
$previous = null;
$i = 0;
foreach ($model as $value => $key) {
$firstLetter = substr($key["name"], 0, 1);
if ($previous !== $firstLetter) {
$result[$firstLetter] = $firstLetter;
$result[$firstLetter[$i]] = $key;
}
// something must be here to assign secons array to
$result[$firstLetter
$previous = $firstLetter;
}
and i get
array (size=4)
'a' =>
array (size=3)
'id' => string '1' (length=1)
'name' => string 'apple' (length=5)
'url' => string 'http://iphone7' (length=14)
'n' =>
array (size=3)
'id' => string '7' (length=1)

'x' =>
array (size=3)
'id' => string '3' (length=1)
'name' => string 'xiaom' (length=5)

You can use array_multisort
array_multisort( array_column($yourArray, "name"), SORT_ASC, $yourArray );
Here is my array;
var_dump($contact['poco']['tags']);
array (size=5)
0 =>
array (size=3)
'tag' => string 'boy' (length=3)
'color' => string '#332409' (length=7)
'id' => string '57160583b0e6df19598b4568' (length=24)
1 =>
array (size=3)
'tag' => string 'girl' (length=4)
'color' => string '#2e2f15' (length=7)
'id' => string '57160589b0e6df1d598b4567' (length=24)
2 =>
array (size=3)
'tag' => string 'zebra' (length=5)
'color' => string '#646604' (length=7)
'id' => string '57160592b0e6df7b588b4567' (length=24)
3 =>
array (size=3)
'tag' => string 'potential duplicate' (length=19)
'color' => string '#f00' (length=4)
'id' => string '57161d9db0e6df0f5c8b456b' (length=24)
4 =>
array (size=3)
'tag' => string 'no phone numbers' (length=16)
'color' => string '#5833d2' (length=7)
'id' => string '5716059ab0e6df7b588b456d' (length=24)
I just want to unset/remove one that have the following tags;
$smartTags = ['potential duplicate', 'no emails', 'no phone numbers'];
So I end up with;
array (size=3)
0 =>
array (size=3)
'tag' => string 'boy' (length=3)
'color' => string '#332409' (length=7)
'id' => string '57160583b0e6df19598b4568' (length=24)
1 =>
array (size=3)
'tag' => string 'girl' (length=4)
'color' => string '#2e2f15' (length=7)
'id' => string '57160589b0e6df1d598b4567' (length=24)
2 =>
array (size=3)
'tag' => string 'zebra' (length=5)
'color' => string '#646604' (length=7)
'id' => string '57160592b0e6df7b588b4567' (length=24)
I have tried;
$smartTags = ['potential duplicate', 'no emails', 'no phone numbers'];
foreach ($contact['poco']['tags'] as $key => $tag) {
if (in_array($tag, $smartTags)) {
unset($contact['poco']['tags'][$key]);
}
}
But it doesn't do anything. I might be having trouble because of the multi-dimensionalness of this array...
What is the correct syntax?
Try up with this.
foreach ($contact['poco']['tags'] as $key => $tag) {
if (in_array($tag['tag'], $smartTags)) {
unset($contact['poco']['tags'][$key]);
}
}
I have just implemented https://github.com/thujohn/twitter-l4 for Laravel 4, it basically pulls in an array
of tweets from a search of a hashtag.
It seems like its working, I think there are some things that are not working though.
I get a blank screen with no errors which means a positive sign.
Here is my code.
PHP:
$tweets = Twitter::getSearch(array('q' => 'secretsocial', 'count' => 100, 'format' => 'array'));
var_dump($tweets);
This code basically gives me an array of json:
array (size=2)
'statuses' =>
array (size=20)
0 =>
array (size=24)
'metadata' =>
array (size=2)
'result_type' => string 'recent' (length=6)
'iso_language_code' => string 'en' (length=2)
'created_at' => string 'Fri May 16 14:28:14 +0000 2014' (length=30)
'id' => int 467310562603331586
'id_str' => string '467310562603331586' (length=18)
'text' => string 'On that #merch #grind. #spotify #swag just got shipped in. #secretsocial #free #leeds #leedsuni… http://t.co/67phqjeg5W' (length=121)
'source' => string 'Instagram' (length=59)

'in_reply_to_status_id' => null
'in_reply_to_status_id_str' => null

'id' => int 167993141
'id_str' => string '167993141' (length=9)

'url' => string 'http://t.co/FL3uuA6QcN' (length=22)
'entities' =>
array (size=2)
'url' =>
array (size=1)
'urls' =>
array (size=1)
0 =>
array (size=4)

'expanded_url' => string 'http://linkd.in/R70tjB' (length=22)
'display_url' => string 'linkd.in/R70tjB' (length=15)
'indices' =>
array (size=2)
0 => int 0
1 => int 22
'description' =>
array (size=1)
'urls' =>
array (size=0)
empty
So from that I wrote this:
if(isset($tweets->statuses) && is_array($tweets->statuses)) {
if(count($tweets->statuses)) {
foreach($tweets->statuses as $tweet) {
echo $tweet->text;
}
}
else {
echo 'The result is empty';
}
}
I get no errors on the page. Can anyone point me in the right direction please?
Cheers
Since each $tweet is an array so you should use $tweet['text'] instead of $tweet->text
foreach($tweets->statuses as $tweet) {
echo $tweet['text'];
}
Also $tweets->statuses should be $tweets['statuses'].

I tried array_shift and array_chunk but nothing works !!!
Please help, thank you all :)
Use array_multisort to sort multi-dimensional arrays or to sort an array using multiple keys.
I think this should do it but it's be a lot cleaner if you didn't have the extra level off the array.
$new_array = array();
$index = 0;
foreach($array as $i1 => $a1){
foreach($a1 as $i2 => $a2){
$new_array[$index][$index] = $a2;
}
$index++;
}
You can use 'array_values' for re-indexing which start index from 0. As per your requirement inner array are not starting from 0 but are same as parent array index. You have to use foreach for that. To index the way you want can be done like this:
$info = array(
0 => array (
0 => array (
'username' => 'wajdi',
'userimage' => 'file_3898.jpg',
'date' => 1373721708,
'postid' => '118',
'type' => 'comment',
'comment' => 'a',
'notify' => '0'
)
),
2 => array (
2 => array (
'username' => 'wajdi',
'userimage' => 'file_3898.jpg',
'date' => 1373721708,
'postid' => '118',
'type' => 'comment',
'comment' => 'a',
'notify' => '0'
)
),
3 => array (
3 => array (
'username' => 'wajdi',
'userimage' => 'file_3898.jpg',
'date' => 1373721708,
'postid' => '118',
'type' => 'comment',
'comment' => 'a',
'notify' => '0'
)
)
);
var_dump($info); // original index
$info = array_values($info);
foreach ($info as $key => $value) {
$temp = array();
foreach($value as $k => $v) {
$temp[$key] = $v;
}
$info[$key] = $temp;
}
var_dump($info); // re-index
array (size=10)

Want to rebuild this array to an more useful array. Like this
array
( [image0] (
'name' =>
'text' =>
'author' =>
'date' =>
'verImage' =>
'imagePicsPath' =>
'imageThumbPath' =>
'imagePath' =>
'imageID' =>
)
[image1] (
'name' =>
'text' =>
'author' =>
'date' =>
'verImage' =>
'imagePicsPath' =>
'imageThumbPath' =>
'imagePath' =>
'imageID' =>
)
And so on depending on how many pictures there is, the keys inside the image array holds the values for each image. Like name, path so on. The incoming array is a $_POST that holds multiple form input data. Need some help to crack this one guys. Need to iterate trough the $_POST array, get the contents and transform to a new array ?
I want unique image arrays that holds the image information before doing my stuff with the database =)
I haven't tested this but it should work:
$incomingArray = $_POST['array'];
$sortedArray = array();
for($i = 0; $i < count($incomingArray); $i++){
foreach($incomingArray as $key => $value){
$sortedArray["image".$i][$key] = $value[i];
}
}
Doing it this way means you don't have to write $sortedArray["image".$i]['NAME'] = $incomingArray['NAME'][$i] for each image value (name, test, author etc.).
Try
foreach( $array as $1st_level_key => $1st_level_value ) {
foreach ( $1st_level_value as $2nd_level_key => $2nd_level_value ) {
$new_array['image'.$2nd_level_key][$1st_level_key] = $2nd_level_value;
}
}
Short answer yes, pretty much like this:
for($i = 0; $i < count($YourArray); $i++)
{
$NewArray["image".$i]["name"] = $YourArray["name"][$i];
...
}
