I would like to replace the value of a multidimensional array if a corrosponding array contains a certain value.
Basically, I have two multidimensional arrays. One contains the actual data and the other contains a yes/no for whether the first array should be modified.
Is there any way to do this:
if optB[i][i] contains 'yes'
then opt[i][i] = '<strong>'.opt[i][i].'</strong>';
I'm lost as to whether this is even possible. Any help would be greatly appreciated -- thank you!
Thank you for the help so far. Here is the array:
[opt] => Array
(
[0] => Array
(
[0] => value1
[1] => value2
)
[1] => Array
(
[0] => value3
[1] => value4
)
)
[optB] => Array
(
[0] => Array
(
[0] => on
)
[1] => Array
(
[1] => on
)
)
Those are some interesting arrays because usually numeric arrays always have a 0. I imagine you may have some different key combination so I think this is the best "future-proof" method:
foreach ($optB as $i => $optB2) {
foreach ($optB2 as $j => $val) {
if ($val) {
$opt[$i][$j] = '<strong>' . $opt[$i][$j] . '</strong>';
}
}
}
It is possible. You can do this:
for ($i = 0; $i < count(opt); $i++) {
if ($optB[$i][$i] == "yes")
opt[$i][$i] = '<strong>'.opt[$i][$i].'</strong>';
}
It can be written like this:
if (strpos($optB[$i][$i], 'yes'))
$opt[$i][$i] = '<strong>'.$opt[$i][$i].'</strong>';
Something along these lines:
foreach ($opt as $i => &$arr) {
foreach ($arr as $j => &$val) {
if ($optB[$i][$j]) {
$val = "<strong>$val</strong>";
}
}
}
Modify as needed.

This has to be easy but I am struggling with it. If the array below exists (named "$startersnames") and I specifically want to echo the value that has "qb" as the key, how do I do that?
I assumed $startersnames['qb'], but no luck.
$startersnames[0]['qb'] works, but I won't know that it's index 0.
Array
(
[0] => Array
(
[qb] => Tannehill
)
[1] => Array
(
[rb] => Ingram
)
[2] => Array
(
[wr] => Evans
)
[3] => Array
(
[wr] => Hopkins
)
[4] => Array
(
[wr] => Watkins
)
[5] => Array
(
[te] => Graham
)
[6] => Array
(
[pk] => Hauschka
)
[7] => Array
(
[def] => Rams
)
[8] => Array
(
[flex] => Smith
)
)
You can use array_column (from php 5.5) like this:
$qb = array_column($startersnames, 'qb');
echo $qb[0];
Demo: http://3v4l.org/QqRuK
This approach is particularly useful when you need to print all the wr names, which are more than one. You can simply iterate like this:
foreach(array_column($startersnames, 'wr') as $wr) {
echo $wr, "\n";
}
You seem to be expecting an array with text keys and value for each, but the array you have shown is an array of arrays: i.e. each numeric key has a value which is an array - the key/value pair where you are looking for the key 'qb'.
If you want to find a value at $array['qb'] then your array would look more like:
$array = [
'qb' => 'Tannehill',
'rb' => 'etc'
];
now $array['qb'] has a value.
If the array you are inspecting is a list of key/value pairs, then you have to iterate over the array members and examine each (i.e. the foreach loop shown in your first answer).
For your multi-dim array, you can loop through the outer array and test the inner array for your key.
function findKey(&$arr, $key) {
foreach($arr as $innerArr){
if(isset($innerArr[$key])) {
return $innerArr[$key];
}
}
return ""; // Not found
}
echo findKey($startersnames, "qb");
You can try foreach loop
$key = "qb";
foreach($startersnames as $innerArr){
if(isset($innerArr[$key])) {
echo $innerArr[$key];
}
}
$keyNeeded = 'qb';
$indexNeeded = null;
$valueNeeded = null;
foreach($startersnames as $index => $innerArr){
//Compare key
if(key($innerArray) === $keyNeeded){
//Get value
$valueNeeded = $innerArr[key($innerArray)];
//Store index found
$indexNeeded = $index;
//Ok, I'm found, let's go!
break;
}
}
if(!empty($indexNeeded) && !empty($valueNeeded)){
echo 'This is your value: ';
echo $startersnames[$indexNeeded]['qb'];
echo 'Or: ':
echo $valueNeeded;
}

I have an array set up like:
Array (
[0] => Array ( [stage] => biometrics [applicant_id] => b79a4c6ea30611e3a3160675fe500303 )
[1] => Array ( [stage] => biometrics [applicant_id] => b79a4c6ea30611e3a3160675fe600303 )
[2] => Array ( [stage] => biometrics [applicant_id] => b79a4c6ea30611e3a3160675fe700303 )
[3] => Array ( [stage] => biometrics [applicant_id] => b79a4c6ea30611e3a3160675fe800303 )
[4] => Array ( [stage] => biometrics_queue [applicant_id] => b79a4c6ea30611e3a3160675fe900303 )
)
First, I want to check to see if there are any duplicate applicant_id's then I need to check the stages for the duplicates. If the applicant_id are the same, but stages are different, they are ok, If the applicant_id's are the same and stages are either the same (biometrics & biometrics) or if it is (biometrics and biometrics_queue) I need to delete that entry from the array.
Not sure how to do this.
.
So here is what I have so far. It works, but there are a lot of loops going on, don't wanna end up using too many resources or getting into an infinite loop...Does anyone see anything wrong with what I'm doing?
First, I used a function called convert stages, so that if there is anything that is a stage name and then _queue appended to the end, it changes it to just the stage name.
foreach ($timer_entry as $key => $value){
$timer_entry[$key]['stage'] = convert_stages($timer_entry[$key]['stage']);
}
Then I have a foreach inside of a for, checking for applicant_id's that might be the same:
for ($i = 0; $i < count($timer_entry); $i++) {
foreach ($timer_entry as $key => $value){
if ($key == $i) {
continue;
}
else {
if ($timer_entry[$key]['applicant_id'] == $timer_entry[$i]['applicant_id']) {
if ($timer_entry[$key]['stage'] == $timer_entry[$i]['stage']) {
unset($timer_entry[$key]);
}
}
}
}
}
If they are the same, I unset them.
I didn't test it, but I think this might do the trick:
$array = array_map('unserialize', array_unique(array_map('serialize', $array)));
How about:
foreach( $myArray as $index => $element )
if (isset($tmp[$element['applicant_id']][str_replace('_queue','',$element['stage'])])
unset($myArray[$index]);
else
$tmp[$element['applicant_id']][str_replace('_queue','',$element['stage'])] = true;
I am having a terrible time getting this to work I have been struggling with it for a couple hours now. Can someone please help me? I have included a fiddle.
I believe my problem is in this string:
$$salesAndOwner[$i]["$salesAndOwner[$i]".$l] = $salesAndOwner[$i.$l][$param] = $values[$l];
Basically I have the following multidimensional array:
[sales] => Array
(
[FirstName] => Array
(
[0] => salesFirst1
[1] => salesFirst2
)
[LastName] => Array
(
[0] => salesLast1
[1] => salesLast2
)
)
[decisionmaker] => Array
(
[FirstName] => Array
(
[0] => dmFirst1
[1] => dmFirst2
)
[LastName] => Array
(
[0] => dmLast1
[1] => dmLast2
)
)
)
I need this to be reorganized like I did with the following array:
Array
(
[additionallocations0] => Array
(
[Address] => Address1
[State] => State1
)
[additionallocations1] => Array
(
[Address] => Address2
[State] => State2
)
)
Here is the original:
Array
(
[additionallocations] => Array
(
[Address] => Array
(
[0] => Address1
[1] => Address2
)
[State] => Array
(
[0] => State1
[1] => State2
)
)
This is how I reorganize the above array:
if(isset($_POST['additionallocations'])) {
$qty = count($_POST['additionallocations']["Address"]);
for ($l=0; $l<$qty; $l++)
{
foreach($_POST['additionallocations'] as $param => $values)
{
$additional['additionallocations'.$l][$param] = $values[$l];
}
}
And this is what I am using for the sales and decisionmaker array. If you notice I have an array that contains sales and decisionmaker in it. I would like to be able to sort any future arrays by just adding its primary arrays name. I feel I am close to solving my problem but I can not get it to produce right.
$salesAndOwner = array(0 => "sales", 1 => "decisionmaker");
for($i = 0; $i < 2; $i++){
$qty = count($_POST[$salesAndOwner[$i]]["FirstName"]);
for ($l=0; $l<$qty; $l++)
{
foreach($_POST[$salesAndOwner[$i]] as $param => $values)
{
$$salesAndOwner[$i]["$salesAndOwner[$i]".$l] = $salesAndOwner[$i.$l][$param] = $values[$l];
}
}
}
In the above code I hard coded 'sales' into the variable I need it to make a variable name dynamically that contains the sales0 decisionmaker0 and sales1 decisionmaker1 arrays so $sales and $decisionmaker
I hope this makes sense please let me know if you need any more info
Let's break it down. Using friendly variable names and spacing will make your code a lot easier to read.
Remember. The syntax is for you to read and understand easily. (Not even just you, but maybe future developers after you!)
So you have an array of groups. Each group contains an array of attributes. Each attribute row contains a number of attribute values.
PHP's foreach is a fantastic way to iterate through this, because you will need to iterate through (and use) the index names of the arrays:
<?php
$new_array = array();
// For each group:
foreach($original_array as $group_name => $group) {
// $group_name = e.g 'sales'
// For each attribute in this group:
foreach($group as $attribute_name => $attributes) {
// $attribute_name = e.g. 'FirstName'
// For each attribute value in this attribute set.
foreach($attributes as $row_number => $attribute) {
// E.g. sales0
$row_key = $group_name . $row_number;
// if this is the first iteration, we need to declare the array.
if(!isset($new_array[$row_key])) {
$new_array[$row_key] = array();
}
// e.g. Array[sales0][FirstName]
$new_array[$row_key][$attribute_name] = $attribute;
}
}
}
?>
With this said, this sort of conversion may cause unexpected results without sufficient validation.
Make sure the input array is valid (e.g. each attribute group has the same number of rows per group) and you should be okay.
$salesAndOwner = array("sales", "decisionmaker");
$result = array();
foreach ($salesAndOwner as $key) {
$group = $_POST[$key];
$subkeys = array_keys($group);
$first_key = $subkeys[0];
foreach ($group[$first_key] as $i => $val) {
$prefix = $key . $i;
foreach ($subkeys as $subkey) {
if (!isset($result[$prefix])) {
$result[$prefix] = array();
}
$result[$prefix][$subkey] = $val;
}
}
}
DEMO
Try
$result =array();
foreach($arr as $key=>$val){
foreach($val as $key1=>$val1){
foreach($val1 as $key2=>$val2){
$result[$key.$key2][$key1] = $val2;
}
}
}
See demo here
Well this has been a headache.
I have two arrays;
$array_1 = Array
(
[0] => Array
(
[id] => 1
[name] => 'john'
[age] => 30
)
[1] => Array
(
[id] => 2
[name] => 'Amma'
[age] => 28
)
[2] => Array
(
[id] => 3
[name] => 'Francis'
[age] => 29
)
)
And another array
array_2 = = Array
(
[0] => Array
(
[id] => 2
[name] => 'Amma'
)
)
How can I tell that the id and name of $array_2 are the same as the id and name of $array_1[1] and return $array_1[1]['age']?
Thanks
foreach($array_1 as $id=>$arr)
{
if($arr["id"]==$array_2[0]["id"] AND $arr["name"]==$array_2[0]["name"])
{
//Do your stuff here
}
}
Well you can do it in a straightforward loop. I am going to write a function that takes the FIRST element in $array_2 that matches something in $array_1 and returns the 'age':
function getField($array_1, $array_2, $field)
{
foreach ($array_2 as $a2) {
foreach ($array_1 as $a1) {
$match = true;
foreach ($a2 as $k => $v) {
if (!isset($a1[$k]) || $a1[$k] != $a2[$k]) {
$match = false;
break;
}
}
if ($match) {
return $a1[$field];
}
}
}
return null;
}
Use array_diff().
In my opinion, using array_diff() is a more generic solution than simply comparing the specific keys.
Array_diff() returns a new array that represents all entries that exists in the first array and DO NOT exist in the second array.
Since your first array contains 3 keys and the seconds array contains 2 keys, when there's 2 matches, array_diff() will return an array containing the extra key (age).
foreach ($array_1 as $arr) {
if (count(array_diff($arr, $array_2[1])) === 1) {//meaning 2 out of 3 were a match
echo $arr['age'];//prints the age
}
}
Hope this helps!
I assume you want to find the age of somebody that has a known id and name.
This will work :
foreach ($array_1 as $val){
if($val['id']==$array_2[0]['id'] && $val['name']==$array_1[0]['name']){
$age = $val['age'];
}
}
echo $age;
Try looking into this.

My question is maybe repetitive but I really find it hard. (I have read related topics)
This is the array :
Array
(
[0] => Array
(
[legend] => 38440
)
[1] => Array
(
[bestw] => 9765
)
[2] => Array
(
[fiuna] => 38779
)
[3] => Array
(
[adam] => 39011
)
[4] => Array
(
[adam] => 39011
)
[5] => Array
(
[adam] => 39011
)
)
I have tried many ways to handle this array and find out the most common value. The result I expect is "adam"
$countwin = array_count_values($winnernames);
$maxwin = max($countwin);
$mostwinner = array_keys($countswin, $maxwin);
EDIT : My array is like this array("A"=>"1" , "B"=>"2" , "A"=>"1") it should return A is the most common
How about iterating your array and counting the values you've got?
$occurences = array();
foreach ($data as $row) {
foreach ($row as $key => $score) {
if (empty($occurences[$key])) {
$occurences[$key] = 1;
} else {
$occurences[$key]++;
}
}
}
and then sorting that
arsort($occurences);
and grabbing the first element of the sorted array
$t = array_keys($occurences);
$winner = array_shift($occurences);
You may try this code. A brute force method indeed. But a quick search made me to find this an useful one:
function findDuplicates($data,$dupval) {
$nb= 0;
foreach($data as $key => $val)
if ($val==$dupval) $nb++;
return $nb;
}
EDIT : Sorry, I misinterpreted your question! But it might be the first hint of finding the one with maximum counter.
