<?php $mypeople=array("age"=>23,"fname"=>"sami","family"=>"soheili","job"=>"Dev", "father" => array("age" => 66
, "name" => "fara"
, "family" => "soheili"
, "job" => "clerk") ); ?>
I know this way for coding array in array but how I can use [] for it?
For example:
<?php $myarr=["name"=>"sami","family"=>"soheili"]
I want make another array inside the [ ], is it possible? (without using array())
Use:
<?php
$myarr=[
"name"=>"sami",
"family"=>"soheili",
"details" => [
"telephone" => "072...",
"email" => "test#yahoo.com"
]
];
This can be done dynamically too.
<?php $arr = ["ar"=>"1","ar2"=>"2"];
print_r( $arr ); // OutPut Array ( [ar] => 1 [ar2] => 2 )
$arr["ar"] = ["ar11"=>"11","ar2"=>"2"];
print_r( $arr["ar"] ); //Output Array ( [ar11] => 11 [ar2] => 2 )
?>

I have a large multidimensional array that looks like the below.
I want to remove duplicate arrays based on the ID, however, I am struggling to achieve this.
I want the duplicates to work over the entire array, so you can see that ID 1229873 is a duplicate, in the array 2021-07-07 and 2021-07-09, it should therefore be removed from 2021-07-09
How would I achieve this? array_unique has not worked for me.
$data = array (
'2021-07-07' =>
array (
0 =>
array (
'id' => 5435435,
'homeID' => 8754,
'match_url' => '/usa/reading-united-ac-vs-ocean-city-noreasters-fc-h2h-stats#1229873',
'competition_id' => 5808,
'matches_completed_minimum' => 12,
),
1 =>
array (
'id' => 1229873,
'homeID' => 8754,
'match_url' => '/usa/reading-united-ac-vs-ocean-city-noreasters-fc-h2h-stats#1229873',
'competition_id' => 5808,
'matches_completed_minimum' => 12,
),
),
'2021-07-09' =>
array (
0 =>
array (
'id' => 3243234,
'homeID' => 8754,
'match_url' => '/usa/reading-united-ac-vs-ocean-city-noreasters-fc-h2h-stats#1229873',
'competition_id' => 5808,
'matches_completed_minimum' => 12,
),
1 =>
array (
'id' => 1229873,
'homeID' => 8754,
'match_url' => '/usa/reading-united-ac-vs-ocean-city-noreasters-fc-h2h-stats#1229873',
'competition_id' => 5808,
'matches_completed_minimum' => 12,
),
),
);
This is a perfect case for array_uunique()! No wait, scratch that. The PHP devs refused to implement it for the perfectly valid reason of... [shuffles notes] "the function name looks like a typo".
[sets notes on fire]
Anyhow, you just need to iterate over that data, keep track of the IDs you've seen, and remove entries that you've already seen.
$seen = [];
foreach(array_keys($data) as $i) {
foreach(array_keys($data[$i]) as $j) {
$id = $data[$i][$j]['id'];
if( in_array($id, $seen) ) {
unset($data[$i][$j]);
} else {
$seen[] = $id;
}
}
}
I've opted for the foreach(array_keys(...) as $x) approach as avoiding PHP references is always the sane choice.
Run it.
I am Sure That is the way which you want to get the unique array.
$unique = array_map("unserialize", array_unique(array_map("serialize", $data)));
echo "<pre>";
print_r($unique);
echo "</pre>";
This is an array of PHP database output：
[
[hi]=>array(
[text] => 'ok'
)
[work]=>array(
[text] => 'usa'
)
[city]=>array(
[text] => 'newyork'
)
]
How do I convert it to look like this:
[
[hi]=> 'ok'
[work]=> 'usa'
[city]=> 'newyork'
]
You just want to loop over the array and build your newly formatted array.
<?php
$arr = [
'please' => [
'text' => 'it'
],
'use' => [
'text' => 'will'
],
'google' => [
'text' => 'help'
]
];
$formattedArr = [];
foreach ($arr as $k => $v) {
$formattedArr[$k] = $v['text'];
}
Another way using some array sorting methods to get us a one liner:
$formattedArr = array_combine( array_keys($arr), array_column($arr, 'text'));
array_combine is a php function that creates a new array using an array for keys and an array for values.
Simply enough, array_keys gets - you guessed it - the keys of the array.
array_column creates an array of a selected property from an inner array, so in this case, it goes plucks the 'text' values from the inner arrays.
I am able to create array values using
$array = array("key" => "value" ... );
Now I want to add them dynamically after assigning the value to $array
<?php
$array = array(
"foo" => "bar",
42 => 24,
"multi" => array(
"dimensional" => array(
"array" => "foo"
)
)
);
var_dump($array["foo"]);
var_dump($array[42]);
var_dump($array["multi"]["dimensional"]["array"]);
?>
This helps you. Refer the php documentation of arrays.
you can access your array by using [] so
$array["new_key"] = "new value";
I would like to add an array to within an existing array.
I am tryin to use array_push which works as long as i dont try to assign a key to the array (if i try to add a key i get a syntax error... :-()
This is my initial array:
$ResultArray = array(
"TransactionDate" => "$TransactionDate",
"tx"=>array(
"0"=>array(
"TxIndex" => "$TxIndex",
"value" => "$Value",
"PaymentConfirmedCount" => "$PaymentConfirmedCount"
),
"1"=>array(
"TxIndex" => "$TxIndex",
"value" => "$Value",
"PaymentConfirmedCount" => "$PaymentConfirmedCount"
)
)
);
i would then like to add:
$ArrayTOAdd = array(
"0"=>array(
"TxIndex" => "$TxIndex",
"value" => "$Value",
"PaymentConfirmedCount" =>
"$PaymentConfirmedCount"
)
);
if I try:
array_push($ResultArray->tx, $ArrayTOAdd);
BUT this does not work and results in a warning of "array_push() [function.array-push]: First argument should be an array"
if i try this :
array_push($ResultArray, $ArrayTOAdd);
it just adds the array but not to $ResultArray->tx
Any suggestions would be greatly welcomed!
You have to access the element in the array with $ResultArray["tx"] and not $ResultArray->tx. The second one is for the access to members in a php class. So an
array_push($ResultArray["tx"], $ArrayTOAdd);
should work.
I have a variable number of multidimensional arrays but all with the same 4 possible values for each item.
For example:
Array
(
[companyid] => 1
[employeeid] => 1
[role] => "Something"
[name] => "Something"
)
but every array may have a different ammount of items inside it.
I want to turn all the arrays into one single table with lots of rows. I tried array_merge() but I end up with a table with 8, 12, 16... columns instead of more rows.
So... any ideas?
Thanks
Didn't test it, but you could try the following:
$table = array();
$columns = array('companyid' => '', 'employeeid' => '', 'role' => '', 'name' => '');
foreach($array as $item) {
$table[] = array_merge($columns, $item);
}
This should work since the documentation about array_merge say:
If the input arrays have the same string keys, then the later value
for that key will overwrite the previous one.
So you either get the value of the current item or a default value that you can specify in the $columns array.
$array1=Array
(
"companyid" => 1,
"employeeid" => 4,
"role" => "Something",
"name" => "Something",
);
$array2=Array
(
"companyid" => array(2,2,2),
"employeeid" => 5,
"role" => "Something2",
"name" => "Something2"
);
$array3=Array
(
"companyid" => 3,
"employeeid" => 6,
"role" => "Something3",
"name" => "Something3"
);
//Using array_merge
$main_array["companyid"]=array_merge((array)$array1["companyid"],(array)$array2["companyid"],(array)$array3["companyid"]);
$main_array["employeeid"]=array_merge((array)$array1["employeeid"],(array)$array2["employeeid"],(array)$array3["employeeid"]);
for($i=0;$i<count($main_array["companyid"]);$i++)
echo $main_array["companyid"][$i] + "<br />";
for($i=0;$i<count($main_array["employeeid"]);$i++)
echo $main_array["employeeid"][$i] + "<br />";
I've tested the code above and seems right.
You coult also improve this code into a DRY function.
