how to remove indexes form an array in php? - arrays

Question

I am looking to except single element from array. My array is:
Array
(
[0] => Array
(
[0] => Array
(
[COUNT(ID)] => 0
)
)
)
I have already use PHP functions basename and array_shift, but they didn't give me proper value. I want only single string COUNT(ID) value.
Here is my function using in cakephp model:
$res = $this->query("select COUNT(ID) from users where Username = '".$Username['Username']."'");
if ($res[0][0]['COUNT(ID)'] >= 1)
{
return false;
}
else
{
return true;
}
I don't need $res[0][0], I need only COUNT[ID]. Is there any easy way to find only COUNT[ID].

Answer 1

If you are using CakePHP, it's good to use model and inbuilt functions to get answer what you want...
$this->loadModel('User'); //If you are in controller
$total = $this->User->find('count', array(
'conditions' => array('Username' => $Username['Username'])
));
You'll get answer in single variable..!!

Answer 2

Your output is produced by code like this
$data = array(
array(
array(
'COUNT(ID)' => 0
)
)
);
You can access its value by calling directly
$data[0][0]['COUNT(ID)']
This could be wrong problem you are solving, as it seems like database query result that should not look like that and could be done with more ease. You should show your original function/problem, that this script is part of.

Answer 3

Let's say you array's name is $myArray, than you can assign the value of $myArray[0][0]['COUNT(ID)'] to $value in the way you usually assign a value: $value = $myArray[0][0]['COUNT(ID)'];.
If you want to delete an index from an array, use unset() like this: unset($myArray[0][0]['COUNT(ID)']). I hope this answers your question.

Answer 4

If you know the exact count of nesting in array you can just access it with indexes
$array[0][0]['COUNT(ID)']
If no, you might want to use the function which will recursively find you the first nested element that is not an array
function getStringFromArray($array) {
if (is_array($array)) {
foreach ($array as $key => $value) {
if (is_array($value)) {
return getStringFromArray($value);
} else {
return $value;
}
}
} else {
throw new Exception("Not an array given");
}
}

If you are sure that array structure will remain same then this could be useful :-
function array_values_recursive($ary)
{
$lst = array();
foreach( array_keys($ary) as $k ){
$v = $ary[$k];
if (is_scalar($v)) {
$lst[] = $v;
} elseif (is_array($v)) {
$lst = array_merge( $lst,
array_values_recursive($v)
);
}
}
return $lst;
}
$arr=array(array(array('COUNT(ID)'=>5)));
$res=array_values_recursive($arr);
echo '<pre>';print_r($res);
output :-
Array
(
[0] => 5
)

Answer 6

You can probably fetch it by associative array to reduce dimension but you can remove index. May be you can use foreach to automatically use indexs.

Answer 7

Try this code:
public $uses = array('User');
$count = $this->User->find('count', array(
'conditions' => array('Username' => $Username['Username'])
));
if ($count >= 1) {
return false;
} else {
return true;
}

Answer 8

You can use following technique for your solution. i did not get you what you want to do with your array but you can try below solution
$arr = Set::extract("/0/COUNT(ID)",$data);
where $data is your input array.
you will get following output
Array
(
[0] => 5
)
