Started learning using CodeIgniter and I am wondering what the best way is to re-do this loop to compare two variables please...
<?php
$user = array('name' => 'name', 'hasCat'=> 1, 'hasDog' => 0);
$pets = array('hasCat', 'hasDog');
foreach($pets as $pet) {
echo ($pet==$user->hasCat) ? 'checked' : '';
the hasCat ^ is the one I want to replace to $pets??
}
?>
You can't access the array value by doing $user->hasCat, that implies hasCat is a variable of the object $user. Try this:
<?php
$user = array('name' => 'name', 'hasCat'=> true, 'hasDog' => false);
$pets = array('hasCat', 'hasDog');
foreach($pets as $pet) {
if($user[$pet]) echo $pet;
}
?>

I need an array like this in PHP?
array = [mani , mani, nithi, nithi, basto]
return in
array = [basto]
not for other elements
Does anyone know how to solve this problem?
<?php
$items = ['mani' , 'mani', 'nithi', 'nithi', 'basto'];
$counts = array_count_values($items);
// Remove elements that occur more than once.
$filtered = array_filter($items, function ($item) use ($counts) {
return $counts[$item] === 1;
});
var_export($filtered);
Output:
array (
4 => 'basto',
)
You may want to specify your question so users here can provide better assistance.
To your issue:
array_unique($array);
https://www.php.net/manual/en/function.array-unique.php
EDIT: you want to search all items by name, to do that you need this function: https://www.php.net/manual/en/function.array-search.php
with your example:
$array = ['mani' , 'mani', 'nithi', 'nithi', 'basto'];
$basto = array_search('basto', $array);
Best,
Sebo

I wanted to output a 3 dimensional array that will come from the Database. This is my database looks like:
Basically, I wanted my first array will be the header_name and under the header_name the sub_header_name will come then underneath is the name
eg:
User Role Management => array(
'' => array (
'Create User Role'
)
),
Config Management => array(
'Organisation' => array('Create Country','Create
Organisation'),
'Site' => array('Create Site','Edit Site')
)
and here are my codes:
$getAllPermission = Permission::get();
$arrHeader = array();
$arrSubHeader = array();
$arrPermissions = array();
// $x = 0;
foreach($getAllPermission as $value){
$title = $value->header_name;
$sub_header_name = $value->sub_header_name;
$permission_name = $value->name;
if ($sub_header_name == ""){
$sub_header_name = 0;
}
array_push($arrPermissions,$permission_name);
$arrHeader[$title] = array($sub_header_name => array($arrPermissions));
//$x++;
}
and my output was like this:
You're pushing onto the same $arrPermissions array every time through the loop, that's why each of the roles gets a longer and longer copy of the permissions array.
You're overwriting $arrHeader[$title] each time through the loop instead of adding a new key to it.
Your desired output has a key of '' for the empty sub_header_name, so I don't see why you have the if that sets $sub_header_name = 0;.
It should simply be:
foreach ($getAllPermissions as $value) {
$arrHeader[$value->header_name][$value->sub_header_name][] = $value->name;
}

I have a complicated JSON and I need create array from this JSON.
I already parsed JSON and create a variablies like this:
$name = $json[response][docs][$i][name][0];
$osm_id = $json[response][docs][$i][osm_id][0];
$place = $json[response][docs][$i][place][0];
$population= $json[response][docs][$i][population][0];
now I need a array, with this variablies, where the $i is changing, like this:
$array = [array_1(name,osm_id,place,population),array_2(name_2,osm_id_2)]
Can you help me with the cycle to fill this array?
If my understanding is correct,
$expected_arr = array();
foreach($json[response][docs] as $inc => $values){
$data = array();
foreach($values as $key => $val){
$data[$key] = $val[0];
}
$expected_arr[$inc] = $data;
}
So you would get something like
array(0 => array( 'name'=>'xxx', 'osm_id'=>'yy',..), 1=> array('name'=>'',.. ,),...)

I want do add values to array in my function to show movies:
$movies = array();
function find_movie($tag) {
// SELECT MOVIE BY %TAG%
$movies[] = $MOVIE;
return 'WATCH MOVIE';
}
Induction:
echo find_movie('cars'); // WATCH MOVIE
My problem is here -> $movies array is empty...
I want to have array with all movies what is showed.
How can I do that ?
You need to pass the $movies array as a reference to make this work out.
Like this..
function find_movie($tag,&$movies){
and call it like..
echo find_movie('cars',$movies);
The code..
<?php
$movies = array();
function find_movie($tag,&$movies) {
$movies[] = "<a href=$tag>WATCH MOVIE</a>";
}
find_movie('cars',$movies);
var_dump($movies);
OUTPUT:
array (size=1)
0 => string '<a href=cars>WATCH MOVIE</a>' (length=28)
