Please see my DEMO and answer my question: why date in values html on offset 2 not as date and it is a number?
DEMO: http://codepad.viper-7.com/r9FYnb
$data = array();
$data_1 = $_POST['data_1'];
$static = $_POST["static"];
foreach($static as $idx=>$val){
$data[] = array(
'data_1' => json_encode(Array($data_1[$idx*2],$data_1[$idx]*2+1)),
'static' => $static[$idx]
);
}
This is output:
Array
(
[0] => Array
(
[data_1] => ["2011\/8\/02",4023] **//4023 !?**
[static] => 12
)
[1] => Array
(
[data_1] => ["2011\/8\/09",4023] **// 4023!?**
[static] => 34
)
[2] => Array
(
[data_1] => ["2011\/8\/16",4023] **// 4023 !?**
[static] => 56
)
)
I'm not certain what you are trying to do here, but I see an inconsistency between how you manipulate $idx
'data_1' => json_encode(Array($data_1[$idx*2],$data_1[$idx]*2+1)),
// -----^^^^^^^^-------^^^^^^^^^^^^
For the second offset, perhaps you intend to modify $idx inside the []
'data_1' => json_encode(Array($data_1[$idx*2],$data_1[($idx*2)+1])),
// ---------------------^^^^^^^^^^^^
Sample output after modifying your demo:
Array
(
[0] => Array
(
[data_1] => ["2011\/8\/02","2011\/8\/08"]
[static] => 12
)
[1] => Array
(
[data_1] => ["2011\/8\/09","2011\/8\/15"]
[static] => 34
)

I have array value like this
Array
(
[0] => Array
(
[channel] => 15
[id] => clsrnMdVKq2omEuQabSCHp83ezAX6w
)
[1] => Array
(
[channel] => 16
[id] => MfSoHUKjD5n90EZbstpiRGY7e8cgh2
)
[2] => Array
(
[channel] => 17
[id] => MfSoHUKjD5n90EZbstpiRGY7e8cgh2
)
)
Now i want to add another array value in specific index .lets say i wants to add this array value at index 1
[1] => Array
(
[channel] => 20
[id] => xxxxxxxxxxxewqeqwexxxxxxxewrewrw
)
Now the result output should be like this
Array
(
[0] => Array
(
[channel] => 15
[id] => clsrnMdVKq2omEuQabSCHp83ezAX6w
)
[1] => Array
(
[channel] => 20
[id] => xxxxxxxxxxxewqeqwexxxxxxxewrewrw
)
[2] => Array
(
[channel] => 16
[id] => MfSoHUKjD5n90EZbstpiRGY7e8cgh2
)
[3] => Array
(
[channel] => 17
[id] => MfSoHUKjD5n90EZbstpiRGY7e8cgh2
)
)
this is my foreach loop to serlize channel and id
foreach ($channel as $key => $ch) {
$user_hash['channel'] = json_encode($ch);
$user_hash['id'] = random_string('alnum', 30);
array_push($user_hash_array, $user_hash);
}
You need to split the array into 2, then insert your new value at the end of the first sub-array, then merge it with the second sub-array. EG: an array which looks like [1,3,4,5] and you want to insert "2" at position 2, then you split at position one to have [1] and [3,4,5]; then you append "2" at the end of first sub-array to form [1,2], then merge this new subarray with the other sub-array([3,4,5]) to form [1,2] + [3,4,5].
For your implementation, try this code:
$array = array() // the original array you want to modify
$insert = array() // the array you want to push into the original one above
$position = 1 // the position at which you want to insert the new item
$newArray = array_slice($array, 0, $position, TRUE) + $insert + array_slice($array, $position, NULL, TRUE);
you can use array_splice array method for add element in array at particular position
<?php
$original_array = array(
array("channel"=>15,"id"=>"sdfdfsf1"),
array("channel"=>16,"id"=>"sdfdfsf2"),
array("channel"=>17,"id"=>"sdfdfsf3")
);
echo "<pre>";print_r($original_array);
$inserted_element =
array(array("channel"=>20,"id"=>"xxxxxxxxxxewqeqwexxxxxxxewrewrw"));
$position=1;
array_splice( $original_array, $position, 0, $inserted_element );
echo "<pre>";print_r($original_array);
?>
Output will be as following
Array
(
[0] => Array
(
[channel] => 15
[id] => sdfdfsf1
)
[1] => Array
(
[channel] => 16
[id] => sdfdfsf2
)
[2] => Array
(
[channel] => 17
[id] => sdfdfsf3
)
)
Array
(
[0] => Array
(
[channel] => 15
[id] => sdfdfsf1
)
[1] => Array
(
[channel] => 20
[id] => xxxxxxxxxxewqeqwexxxxxxxewrewrw
)
[2] => Array
(
[channel] => 16
[id] => sdfdfsf2
)
[3] => Array
(
[channel] => 17
[id] => sdfdfsf3
)
)
I want to remove parent array index in array.
Following is my array.
Array
(
[0] => Array
(
[0] => Array
(
[id] => 296
[username] => David0123
[profile_slug] => david-love
)
)
[1] => Array
(
[0] => Array
(
[id] => 297
[username] => Anne_wils
[profile_slug] => anne-chase
)
)
[2] => Array
(
[0] => Array
(
[id] => 300
[username] => malina001
[profile_slug] => malina-reid
)
)
)
And I want like this way..
Array(
[0] => Array
(
[id] => 296
[username] => David0123
[profile_slug] => david-love
)
[1] => Array
(
[id] => 297
[username] => Anne_wils
[profile_slug] => anne-chase
)
[2] => Array
(
[id] => 300
[username] => malina001
[profile_slug] => malina-reid
)
)
I used following script for it but not work.
$myMainArray = json_decode(json_encode($allEscorts),true);
$i=0;
foreach( array_values($myMainArray) as $k=> $val){
echo $val[$i]['id'];
$i++;
}
I want to display data each element but first i have to remove parent array indexes.
You can use array_map to pull values up one level
$myMainArray = json_decode(json_encode($allEscorts),true);
$myMainArray = array_map(function($el) {
return $el[0];
}, $myMainArray);
You should check if the first array could be generate as you wish.
If not you can use array_map to get the first index from the inner-array.
for example:
$result = array_map(function($item){
return $item[0]; // always return the first array-index
}, $first_array);
I am working in PHP so I have an array like this, from this array I want filter take user_id to another array like I given below.
Array
(
[0] => Array
(
[user_id] => 66
[distance] => 0
)
[1] => Array
(
[user_id] => 68
[distance] => 0
)
[2] => Array
(
[user_id] => 81
[distance] => 0
)
[3] => Array
(
[user_id] => 65
[distance] => 0.00010218008081861118
)
)
I want an array like this,
$user_id=array(66,68,81,65);
Use array_column()
Returns an array of values representing a single column from the input array.
<?php
$user_array = array(
0 => array('user_id' => 1, 'name' => 'Bob'),
1 => array('user_id' => 2, 'name' => 'John'),
2 => array('user_id' => 3, 'name' => 'Mary')
);
$users = array_column($user_array, 'user_id');
print_r($users);
Output :
Array
(
[0] => 1
[1] => 2
[2] => 3
)
Where $array is the multidimensional array you provided above:
$data = array();
foreach ($array as $item) {
$data[] = $item['user_id'];
}
print_r($data);
There is an array which is built looks like the following (with some more values which i left away for this example):
Array
(
[0] => Array
(
[id] => 44
[cars] => Array
(
[0] => Array
(
[id] => 38
)
[1] Array
(
[id] => 39
)
)
)
[1] => Array
(
[id] => 45
[cars] => Array
(
[0] => Array
(
[id] =>136
)
[1] =>Array
(
[id] =>137
)
[2] =>Array
(
[id] =>138
)
)
)
)
I want to build another array from the above in the following form:
Array
(
[0] => Array
(
['car_filter_sort_id'] => 44
['car_id'] => 38
)
[1] => Array
(
['car_filter_sort_id'] => 44
['car_id'] => 39
)
[2] => Array
(
['car_filter_sort_id'] => 45
['car_id'] => 136
)
[3] => Array
(
['car_filter_sort_id'] => 45
['car_id'] => 137
)
[4] => Array
(
['car_filter_sort_id'] => 45
['car_id'] => 138
)
)
I tried to achieve this with following function:
foreach($filterSortSaveArray as $filterSortSaveArray['cars'] => $value){
$id = $filterSortSaveArray['id'];
foreach($value['cars'] as $value => $car){
$field_values['car_filter_sort_id'] = $id;
$field_values['car_id'] = $car['id'];
}
}
But the the result differs from what I have expected. Any suggestions?
There are two big issues in your code. First, are you referencing undefined value with $filterSortSaveArray['cars'], since there is no 'cars' key in the first level of the original array. Second, by assigning values to $field_values['car_filter_sort_id'] and $field_values['car_id'] in the loop you are just overriding them in each iteration. You need to push the values into an array using []= operator (which is equivalent to applying array_push()).
Try this:
$result = [];
foreach($filterSortSaveArray as $k => $v) {
if (!is_array($v['cars']))
continue;
$id = $v['id'];
foreach ($v['cars'] as $i => $car){
$result[] = [
'car_filter_sort_id' => $id,
'car_id' => $car['id']
];
}
}
I have following arrays:
1) for total placed

(
[totalplaced] => 8
)
)
[1] => Array
(
[centers] => Array
(
[name] => mumbai
[id] => 2

[0] => Array
(
[totalplaced] => 1
)
)
)
2) for total working

(
[centers] => Array
(
[name] => mumbai
[id] => 2
)
[0] => Array
(
[totaltrained] => 1
)
)
)
I wanted to merge these arrays so that the resultant array should look like this
[newarray] => Array(
[0] => Array (
[centers] => Array
(
[name] => delhi
[id] => 1
[totalplaced] => 8
[totalworking] => 4
[totaltrained] => 8
)
)
[1]=> Array(
[centers] => Array
(
[name] => mumbai
[id] => 2
[totalplaced] => 1
[totalworking] => 1
[totaltrained] => 1
)
)
)
This is the tabular representation of the above data which i want to display
centername totalplaced totalworking totaltrained
delhi 8 4 8
mumbai 1 1 1
Please help me on this.
Thanks

The difficulty here is that PHP's functions such as array_merge() and array_merge_recursive() will not merge data into numeric keys, but rather will re-key any duplicate numeric key. So for example given two arrays:
array(
'test' => 'abc',
0 => 'xyz'
);
array(
'test' => 'def',
0 => 'uvw'
);
Merging them together with array_merge() will produce an array like:
array(
'test' => 'def',
0 => 'xyz',
1 => 'uvw'
);
So, you need a custom function to be "additive" on any key, regardless of whether it is a string or numeric key. Try this:
function mixed_key_array_merge() {
$args = func_get_args();
$result = array();
foreach ($args as $arg) {
// discard non-array arguments; maybe this could be better handled
if (!is_array($arg)) {
continue;
}
foreach ($arg as $key => $value) {
if (!isset($result[$key])) {
$result[$key] = $value;
} else if (is_array($result[$key])) {
$result[$key] = call_user_func_array('mixed_key_array_merge',array($result[$key],$value));
}
}
}
return $result;
}
