I have an nested array that's a mix of words and numbers. It looks like this conceptually. I need to process only numbered indexes such as 15 and 28. I guess this means that I can't use a foreach loop (or is there a way I could). How would you do this?
myarray = (
someindex = (
field1 =
field2 =
);
15 = (
field1 =
field2 =
);
28 = (
field1 =
field2 =
);
anothertext = (
field1 =
field2 =
);
);
foreach($myarr as $key => $item)
{
if(is_int($key))
{
// Do processing here
}
}
Yes, that will loop through every item in the array, so if you wanted to process the other items separately, you could just add in an else block.
Edit: Changed is_numeric to is_int. See comments for explanation.
You can use foreach
foreach($myarray as $key=>$value)
{
if(is_int($key))
{
//process the entry as you want
}
}
You could use a FilterIterator with foreach:
class IntKeyFilterIterator extends FilterIterator {
public function accept() {
return is_int(parent::key());
}
}
$it = new IntKeyFilterIterator(new ArrayIterator($array));
foreach ($it as $value) {
// Will only have those with int keys
}
Another version. Grep the source array for any purely numeric keys, then loop over that result array and do the processing.
$keys = preg_grep('/^\d+$/', array_keys($myarray)) {
foreach($keys as $key) {
doSomething($myarray[$key]);
}

i have this code, want to count as per there value like count 30*4, 35*2, 50*2 & 34*1.
i have already tried:
$counts = array();
foreach ($array as $key=>$subarr) {
// Add to the current group count if it exists
if (isset($counts[$subarr['group']]) {
$counts[$subarr['group']]++;
}
// or initialize to 1 if it doesn't exist
else $counts[$subarr['group']] = 1;
// Or the ternary one-liner version
// instead of the preceding if/else block
$counts[$subarr['group']] = isset($counts[$subarr['group']]) ? $counts[$subarr['group']]++ : 1;
}
but my problem still there
You can merge all the inner arrays into one with array_merge and then use array_count_values to get the counts.
$counts = array_count_values(array_merge(...$feetypes));
Merge all the subarray into a single array and apply array_count_values function to get the result
function merageAll($arr) {
$flatArray = array();
foreach($arr as $element) {
if (is_array($element)) {
$flatArray = array_merge($flatArray, merageAll($element));
} else {
$flatArray[] = $element;
}
}
return $flatArray;
}
$res = array_count_values(merageAll($feetypes));
Result
Array
(
[30] => 4
[35] => 2
[50] => 2
[34] => 1
)
function merageAll work if there are values and sub arrays in the array.
Working DEMO LINK
I used recursion in case values are more than two levels deep. note the $count variable is passed by reference to the function due to recursion.
<?php
$feetypes=[
[30,35,50],
[30,35],
[30,50],
[30,34]
];
$counts = array();
function countValues($arr, &$count) {
foreach($arr as $subval) {
if(is_array($subval)) {
countValues($subval,$count);
} else {
if(isset($count[$subval])) {
$count[$subval] += 1;
} else {
$count[$subval] = 1;
}
}
}
}
countValues($feetypes,$counts);
print_r($counts);
So currently I have an array that pulls data based on an attribute and it puts the data in its own seperate array. What I need to do is to put these 3 arrays into one, so if one of them is null, it won't give me errors. It should be fairly simply but I can't wrap my head around it.
//CV eqpValue
if (is_array(FullDataResponse->dlr->DesignLayoutRecord)) {
foreach(FullDataResponse->dlr->DesignLayoutRecord as $DesignLayoutRecord_key => $DesignLayoutRecord_value ) {
if ($DesignLayoutRecord_value->cktEqpOptions->CktEqpOptions && is_array($DesignLayoutRecord_value->cktEqpOptions->CktEqpOptions)) {
foreach ($DesignLayoutRecord_value->cktEqpOptions->CktEqpOptions as $cv_obj)
{
if($cv_obj->attribute === 'CDR')
{
$this->cvCDRList[] = array("cdr" => $cv_obj->eqpValue);
}
if($cv_obj->attribute === 'CUSTOMER')
{
$this->cvCustomerList[] = array("customer" => $cv_obj->eqpValue);
}
if($cv_obj->attribute === 'LEASE LINE')
{
$this->cvphoneList[] = array("phoneNumber" => $cv_obj->eqpValue);
}
}
}
}
}
See how they are currently put into separate arrays like cvCDRList, cvCustomerList, and cvphoneList? How would I put them into a single array? Thanks!!
you can use array_merge.
<?php
$array1 = array("a12","a12","a13");
$array2 = array("a21","a22","a23");
$array3 = array("a31","a32","a33");
$finalArray = array_merge($array1,$array2,$array3);
foreach( $finalArray as $key => $value ){
echo $key."=>".$value."<br>";
}
?>
You can create another property called "allAtributes" .
When you finalize to fill your 3 arrays you can call to another method of class than make the merge between 3 array.
The finally you will have got like this :
allAtributes (array)=>{
["cdr"](array)=> {
['cdrkey1'] = cdrAtt1 ,
['cdrKey2'] = cdrAtt2 ...
},
["customer"](array)=> {
['customerkey1'] = customerAtt1 ,
['customerKey2'] = customerAtt2 ...
},
["phoneNumber"](array)=> {
['phoneNumberkey1'] = phoneNumberAtt1 ,
['phoneNumberKey2'] = phoneNumberAtt2 ...
}
}
You only must declare an array an add the other three arrays with the function array_merge into loops
I need compare 2 arrays , the first array have one order and can´t change , in the other array i have different values , the first array must compare his id with the id of the other array , and if the id it´s the same , take the value and replace for show all in the same order
For Example :
$array_1=array("1a-dogs","2a-cats","3a-birds","4a-people");
$array_2=array("4a-walking","2a-cats");
The Result in this case i want get it´s this :
"1a-dogs","2a-cats","3a-birds","4a-walking"
If the id in this case 4a it´s the same , that entry must be modificate and put the value of other array and stay all in the same order
I do this but no get work me :
for($fte=0;$fte<count($array_1);$fte++)
{
$exp_id_tmp=explode("-",$array_1[$fte]);
$cr_temp[]="".$exp_id_tmp[0]."";
}
for($ftt=0;$ftt<count($array_2);$ftt++)
{
$exp_id_targ=explode("-",$array_2[$ftt]);
$cr_target[]="".$exp_id_targ[0]."";
}
/// Here I tried use array_diff and others but no can get the results as i want
How i can do this for get this results ?
Maybe you could use the array_udiff_assoc() function with a callback
Here you go. It's not the cleanest code I've ever written.
Runnable example: http://3v4l.org/kUC3r
<?php
$array_1=array("1a-dogs","2a-cats","3a-birds","4a-people");
$array_2=array("4a-walking","2a-cats");
function getKeyStartingWith($array, $startVal){
foreach($array as $key => $val){
if(strpos($val, $startVal) === 0){
return $key;
}
}
return false;
}
function getMergedArray($array_1, $array_2){
$array_3 = array();
foreach($array_1 as $key => $val){
$startVal = substr($val, 0, 2);
$array_2_key = getKeyStartingWith($array_2, $startVal);
if($array_2_key !== false){
$array_3[$key] = $array_2[$array_2_key];
} else {
$array_3[$key] = $val;
}
}
return $array_3;
}
$array_1 = getMergedArray($array_1, $array_2);
print_r($array_1);
First split the 2 arrays into proper key and value pairs (key = 1a and value = dogs). Then try looping through the first array and for each of its keys check to see if it exists in the second array. If it does, replace the value from the second array in the first. And at the end your first array will contain the result you want.
Like so:
$array_1 = array("1a-dogs","2a-cats","3a-birds","4a-people");
$array_2 = array("4a-walking","2a-cats");
function splitArray ($arrayInput)
{
$arrayOutput = array();
foreach ($arrayInput as $element) {
$tempArray = explode('-', $element);
$arrayOutput[$tempArray[0]] = $tempArray[1];
}
return $arrayOutput;
}
$arraySplit1 = splitArray($array_1);
$arraySplit2 = splitArray($array_2);
foreach ($arraySplit1 as $key1 => $value1) {
if (array_key_exists($key1, $arraySplit2)) {
$arraySplit1[$key1] = $arraySplit2[$key1];
}
}
print_r($arraySplit1);
See it working here:
http://3v4l.org/2BrVI
$array_1=array("1a-dogs","2a-cats","3a-birds","4a-people");
$array_2=array("4a-walking","2a-cats");
function merge_array($arr1, $arr2) {
$arr_tmp1 = array();
foreach($arr1 as $val) {
list($key, $val) = explode('-', $val);
$arr_tmp1[$key] = $val;
}
foreach($arr2 as $val) {
list($key, $val) = explode('-', $val);
if(array_key_exists($key, $arr_tmp1))
$arr_tmp1[$key] = $val;
}
return $arr_tmp1;
}
$result = merge_array($array_1, $array_2);
echo '<pre>';
print_r($result);
echo '</pre>';
This short code works properly, you'll get this result:
Array
(
[1a] => dogs
[2a] => cats
[3a] => birds
[4a] => walking
)
I got stuck somehow on the following problem:
What I want to achieve is to merge the following arrays based on key :
{"Entities":{"submenu_id":"Parents","submenu_label":"parents"}}
{"Entities":{"submenu_id":"Insurers","submenu_label":"insurers"}}
{"Users":{"submenu_id":"New roles","submenu_label":"newrole"}}
{"Users":{"submenu_id":"User - roles","submenu_label":"user_roles"}}
{"Users":{"submenu_id":"Roles - permissions","submenu_label":"roles_permissions"}}
{"Accounting":{"submenu_id":"Input accounting data","submenu_label":"new_accounting"}}
Which needs to output like this:
[{"item_header":"Entities"},
{"list_items" :
[{"submenu_id":"Parents","submenu_label":"parents"},
{"submenu_id":"Insurers","submenu_label":"insurers"}]
}]
[{"item_header":"Users"},
{"list_items" :
[{"submenu_id":"New roles","submenu_label":"newrole"}
{"submenu_id":"User - roles","submenu_label":"user_roles"}
{"submenu_id":"Roles - permissions","submenu_label":"roles_permissions"}]
}]
[{"item_header":"Accounting"},
{"list_items" :
[{"submenu_id":"Input accounting data","submenu_label":"new_accounting"}]
}]
I have been trying all kinds of things for the last two hours, but each attempt returned a different format as the one required and thus failed miserably. Somehow, I couldn't figure it out.
Do you have a construction in mind to get this job done?
I would be very interested to hear your approach on the matter.
Thanks.
$input = array(
'{"Entities":{"submenu_id":"Parents","submenu_label":"parents"}}',
'{"Entities":{"submenu_id":"Insurers","submenu_label":"insurers"}}',
'{"Users":{"submenu_id":"New roles","submenu_label":"newrole"}}',
'{"Users":{"submenu_id":"User - roles","submenu_label":"user_roles"}}',
'{"Users":{"submenu_id":"Roles - permissions","submenu_label":"roles_permissions"}}',
'{"Accounting":{"submenu_id":"Input accounting data","submenu_label":"new_accounting"}}',
);
$input = array_map(function ($e) { return json_decode($e, true); }, $input);
$result = array();
$indexMap = array();
foreach ($input as $index => $values) {
foreach ($values as $k => $value) {
$index = isset($indexMap[$k]) ? $indexMap[$k] : $index;
if (!isset($result[$index]['item_header'])) {
$result[$index]['item_header'] = $k;
$indexMap[$k] = $index;
}
$result[$index]['list_items'][] = $value;
}
}
echo json_encode($result);
Here you are!
In this case, first I added all arrays into one array for processing.
I thought they are in same array first, but now I realize they aren't.
Just make an empty $array=[] then and then add them all in $array[]=$a1, $array[]=$a2, etc...
$array = '[{"Entities":{"submenu_id":"Parents","submenu_label":"parents"}},
{"Entities":{"submenu_id":"Insurers","submenu_label":"insurers"}},
{"Users":{"submenu_id":"New roles","submenu_label":"newrole"}},
{"Users":{"submenu_id":"User - roles","submenu_label":"user_roles"}},
{"Users":{"submenu_id":"Roles - permissions","submenu_label":"roles_permissions"}},
{"Accounting":{"submenu_id":"Input accounting data","submenu_label":"new_accounting"}}]';
$array = json_decode($array, true);
$intermediate = []; // 1st step
foreach($array as $a)
{
$keys = array_keys($a);
$key = $keys[0]; // say, "Entities" or "Users"
$intermediate[$key] []= $a[$key];
}
$result = []; // 2nd step
foreach($intermediate as $key=>$a)
{
$entry = ["item_header" => $key, "list_items" => [] ];
foreach($a as $item) $entry["list_items"] []= $item;
$result []= $entry;
}
print_r($result);
I would prefer an OO approach for that.
First an object for the list_item:
{"submenu_id":"Parents","submenu_label":"parents"}
Second an object for the item_header:
{"item_header":"Entities", "list_items" : <array of list_item> }
Last an object or an array for all:
{ "Menus: <array of item_header> }
And the according getter/setter etc.
The following code will give you the requisite array over which you can iterate to get the desired output.
$final_array = array();
foreach($array as $value) { //assuming that the original arrays are stored inside another array. You can replace the iterator over the array to an iterator over input from file
$key = /*Extract the key from the string ($value)*/
$existing_array_for_key = $final_array[$key];
if(!array_key_exists ($key , $final_array)) {
$existing_array_for_key = array();
}
$existing_array_for_key[count($existing_array_for_key)+1] = /*Extract value from the String ($value)*/
$final_array[$key] = $existing_array_for_key;
}
I have the following code:
$rt1 = array
(
'some_value1' => 'xyz1',
'some_value2' => 'xyz2',
'value_1#30'=>array('0'=>1),
'value_2#30'=>array('0'=>2),
'value_3#30'=>array('0'=>3),
'value_1#31'=>array('0'=>4),
'value_2#31'=>array('0'=>5),
'value_3#31'=>array('0'=>6),
'some_value3' => 'xyz3',
'some_value4' => 'xyz4',
);
$array_30 = array
(
'0'=>1,
1=>'2',
2=>'3'
);
$array_31 = array
(
'0'=>4,
'1'=>'5',
'2'=>'6'
);
I need to make it an array and insert the array_30 and array_31 into a DB.
foreach($rt1 as $value){
$rt2[] = $value['0'];
}
The question was updated, so here is an updated answer. Quick check, you should really try and update this to whatever more generic purpose you have, but as a proof of concept, a runnable example:
<?php
$rt1 = array
(
'some_value1' => 'xyz1',
'some_value2' => 'xyz2',
'value_1#30'=>array('0'=>1),
'value_2#30'=>array('0'=>2),
'value_3#30'=>array('0'=>3),
'value_1#31'=>array('0'=>4),
'value_2#31'=>array('0'=>5),
'value_3#31'=>array('0'=>6),
'some_value3' => 'xyz3',
'some_value4' => 'xyz4',
);
$finalArrays = array();
foreach($rt1 as $key=>$value){
if(is_array($value)){
$array_name = "array_".substr($key,-2);
${$array_name}[] = $value['0'];
}
}
var_dump($array_30);
var_dump($array_31);
?>
will output the two arrays with the numbers 1,2,3 and 4,5,6 respectivily
i assume you want to join the values of each of the second-level arrays, in which case:
$result = array();
foreach ($rt1 as $arr) {
foreach ($arr as $item) {
$result[] = $item;
}
}
Inspired by Nanne (which reminded me of dynamically naming variables), this solution will work with every identifier after the \#, regardless of its length:
foreach ( $rt1 as $key => $value )
{
if ( false == strpos($key, '#') ) // skip keys without #
{
continue;
}
// the part after the # is our identity
list(,$identity) = explode('#', $key);
${'array_'.$identity}[] = $rt1[$key]['0'];
}
Presuming that this is your actual code, probably you will need to copy the array somewhere using foreach and afterwards create the new array as you wish:
foreach($arr as $key => $value) {
$arr[$key] = 1;
}
