I want to get the combination keys for an array - here the example:
$keys = array(
array(
'original',
'section 1',
'section 2'
),
array(
'original',
'section 1'
),
array(
'original',
'section 1'
),
array(
'original',
'section 1',
'section 2'
),
array(
'original',
'section 1'
)
);
all original sections would be 00000 (5 digits because of 5 different arrays, but there can be 1 to n arrays, not limited to 5) and variation #15 would be for example 01010. i basically want to get a list of all variations in a list with that key to get them. we assume that there are not more than 9 sections + original inside each array.
output should look like this:
array(
array(
"key" => "00000",
"data" => array(
"original", "original", "original", "original", "original"
)
),
array(
"key" => "10000",
"data" => array(
"section 1", "original", "original", "original", "original"
)
),
array(
"key" => "20000",
"data" => array(
"section 2", "original", "original", "original", "original"
)
),
array(
"key" => "01000",
"data" => array(
"original", "section 1", "original", "original", "original"
)
)
[...]
)
in addition to this it would be nice to have a good way to get it the other way too. giving the key 01010 and getting all sections back.
thanks!
Here is what i came up with:
$options = array();
$counter1 = 0;
foreach($keys as $values) {
$counter1++;
$counter2 = 0;
$options[$counter1] = array();
foreach($values as $key => $value) {
if(isset($options[($counter1 - 1)])) {
foreach($options[($counter1 - 1)] as $old_val) {
$counter2++;
$old_array = $old_val['data'];
array_push($old_array, $value);
$options[$counter1][$counter2] = array();
$options[$counter1][$counter2]['key'] = $old_val['key'] . $key;
$options[$counter1][$counter2]['data'] = $old_array;
}
}
else {
$counter2++;
$options[$counter1][$counter2] = array();
$options[$counter1][$counter2]['key'] = $key;
$options[$counter1][$counter2]['data'] = array($value);
}
}
}
$all_options = end($options);
You get 72 results which is correct because it is 3 * 2 * 2 * 3 * 2 = 72

How to modify an array based on the value as key?
array(
array(
"name" => "BIBAR",
"cutoff" => 20220725,
"totals" => 5614
),
array(
"name" => "BIBAR",
"cutoff" => 20220810,
"totals" => 5614
),
array(
"name" => "BIBAR",
"cutoff" => 20220825,
"totals" => 5614
)
);
I tried the following but it's not working:
foreach($cutoffs as $catoff) {
$ii = 0;
$sums[$ii][$catoff] = array_filter($array, function($val){
return $val['cutoff'] === $catoff ? $val['totals'] : $val;
});
$ii++;
}
My desired array:
array(
'20221025' => array(
12345,
12343,
24442
),
'20221110' => array(
3443,
744334
)
)
I'm stuck here for hours ... Please help
IF the "name" is irrelevant, I think also the previous answer should be fine.
If this code does "not work", then your explanation might be wrong, so you need to either explain better, or give us more examples - please mind that in your example the input and output are very different - the input you gave does not match your ouput.
My code is:
$a = array(
array(
"name" => "BIBAR",
"cutoff" => 20220725,
"totals" => 5614
),
array(
"name" => "BIBAR",
"cutoff" => 20220810,
"totals" => 5614
),
array(
"name" => "BIBAR",
"cutoff" => 20220725,
"totals" => 1234
)
);
print_r($a);
echo "\n================================\n\n";
$newArr = [];
foreach ($a as $k => $vArr) {
// maybe some validation would be useful here, check if they keys exist
$newArr[$vArr['cutoff']][] = $vArr['totals'];
}
print_r($newArr);
function changeArr($data){
$new = [];
foreach ($data as $v){
$new[$v['cutoff']][] = $v['totals'];
}
return $new;
}
I'm trying to wrap my head around how to accomplish this…
I have an that's something like:
$contributors = array(
[0] => array(
[name] => 'John',
[role] => 'author',
),
[1] => array(
[name] => 'Gail',
[role] => 'author',
),
[2] => array(
[name] => 'Beth',
[role] => 'illustrator',
),
)
I'm trying to use this information to construct a detailed byline, like:
Written by John and Gail. Designed by Beth.
I need to compare each role to the previous and next ones in order to:
Use a label before the first instance of each role
Separate multiple instances of the same role with a comma
Use "and" instead of a comma before the last instance of each role
I'm no PHP expert so I'm having a hard time figuring out how to approach this! I have a function to output the right label depending on the role, but it's the comparisons I can't seem to figure out. I've considered foreach and while loops, but neither seems up to the job. I've never used a for loop so I don't know if it applies.
Some additional background:
I'm working with WordPress and the Advanced Custom Fields plugin.
$contributors is the value of an ACF Repeater field, where name and role are subfields. (I've simplified the names to make things easier.)
You can group the array per role and use array_pop to remove the element. implode the remaining array elements and just append the popped value.
$contributors = array(
array(
"name" => 'John',
"role" => 'author',
),
array(
"name" => 'Gail',
"role" => 'author',
),
array(
"name" => 'Jose',
"role" => 'author',
),
array(
"name" => 'Thomas',
"role" => 'author',
),
array(
"name" => 'Beth',
"role" => 'illustrator',
),
array(
"name" => 'Mary',
"role" => 'producer',
),
array(
"name" => 'Criss',
"role" => 'producer',
),
);
//Grouped the names according to role
$grouped = array_reduce($contributors, function($c, $v) {
if ( !isset( $c[ $v['role'] ] ) ) $c[ $v['role'] ] = array();
$c[ $v['role'] ][] = $v['name'];
return $c;
}, array());
//Construct final Array
$final = array();
foreach( $grouped as $key => $group ) {
$last = array_pop( $group );
if ( count( $group ) == 0 ) $final[ $key ] = $last; /* One one name on the role, no need to do anything*/
else $final[ $key ] = implode( ", ", $group ) . " and " . $last;
}
echo "<pre>";
print_r( $final );
echo "</pre>";
This will result to:
Array
(
[author] => John, Gail, Jose and Thomas
[illustrator] => Beth
[producer] => Mary and Criss
)
You can now use it as
echo 'Written by ' . $final["author"] . '. Designed by ' . $final["illustrator"] . '. Produced by ' . $final["producer"];
And will result to:
Written by John, Gail, Jose and Thomas. Designed by Beth. Produced by
Mary and Criss
You can try like this -
$contributors = array(
array(
'name' => 'John',
'role' => 'author',
),
array(
'name' => 'Gail',
'role' => 'author',
),
array(
'name' => 'Ali',
'role' => 'author',
),
array(
'name' => 'Beth',
'role' => 'illustrator',
)
);
#This function prepare array to expected String
function PrepareArray($data){
$combined = '';
if (count($data)>1) {
$last = array_slice($data, -1);
$first = join(', ', array_slice($data, 0, -1));
$both = array_filter(array_merge(array($first), $last), 'strlen');
$combined = join(' and ', $both);
}else{
$combined = implode('', $data);
}
return $combined;
}
$authors = array();
$designers = array();
foreach ($contributors as $key => $value) {
if ($value['role']=='author') {
$authors[] = $value['name']; #Keep Authors name in Array
}else if ($value['role']=='illustrator') {
$designers[] = $value['name']; #Keep Designers name in Array
}
}
$authors = PrepareArray($authors);
$designers = PrepareArray($designers);
echo "Written by {$authors}. Designed by {$designers}.";
Output :
Written by John, Gail and Ali. Designed by Beth.
Try below code:
<?php
$contributors = array(
0 => array(
'name' => 'John',
'role' => 'author',
),
1 => array(
'name' => 'Gail',
'role' => 'author',
),
2 => array(
'name' => 'Beth',
'role' => 'illustrator',
),
3 => array(
'name' => 'Albert',
'role' => 'author',
),
);
$labels = ['author'=>'Written by', 'illustrator'=>'Designed by', 'producer'=>'Produced by'];
$new_contributors = [];
foreach($contributors as $cont){
$new_contributors[$cont['role']][] = $cont['name'];
}
$str = '';
foreach($labels as $role=>$label){
if(isset($new_contributors[$role]) && is_array($new_contributors[$role])){
$str .= ' '.$label.' ';
foreach($new_contributors[$role] as $key=>$new_contributor){
$count = count($new_contributors[$role]);
if(($count - $key) == 1 ){
$str .= ' and ';
$str .= $new_contributor;
}else if(($count - $key) == 2){
$str .= $new_contributor;
}else{
$str .= $new_contributor.', ';
}
}
}
}
echo $str;
I would like in php to stop duplicate messages by logging msgid to a text file using something like this file_put_contents("a.txt", implode(PHP_EOL, $array1), FILE_APPEND);
and then converting it back to an array using $array1 = file("a.txt"); I would also like to delete messages from the array if they are from a set name
I know how to convert json to an array $array1 = json_decode($json, true);

Hi use the following code, first test it out accordingly
$uniqueMessages = unique_multidim_array($messages,'msg');
Usage : Pass the key as the 2nd parameter for which you need to check the uniqueness of array.
<?php
/* Function to handle unique assocative array */
function unique_multidim_array($array, $key) {
/* temp array to hold unique array */
$temp_array = array();
/* array to hold */
$i = 0;
/* array to hold the key for unique array */
$key_array = array();
foreach($array as $val) {
if (!in_array($val[$key], $key_array)) {
$key_array[$i] = $val[$key];
$temp_array[$i] = $val;
}
$i++;
}
return $temp_array;
}
$messages = array(
0 => array(
'info' => array(
'name' => 'example'
),
'msg' => 'example',
'msgid' => 'example'
),
1 => array(
'info' => array(
'name' => 'example 1'
),
'msg' => 'example 1',
'msgid' => 'example 1'
),
3 => array(
'info' => array(
'name' => 'example'
),
'msg' => 'example',
'msgid' => 'example'
)
);
echo '<pre>';
echo '*****************BEFORE***********************<br/>';
var_dump($messages);
echo '*****************AFTER***********************<br/>';
$uniqueMessages = unique_multidim_array($messages,'msg');
var_dump($uniqueMessages);
This works for me this is an modded function click here for original function
function RemoveElementByArray($array, $key, $seen){
foreach($array as $subKey => $subArray){
if(in_array($subArray[$key], $seen)){
unset($array[$subKey]);
}
}
return $array;
}
Example:
$array = array(
array("id" => "1", "name" => "example1"),
array("id" => "2", "name" => "example2"),
array("id" => "3", "name" => "example3"));
$SeenArray = array("1", "2");
print_r(RemoveElementByArray($array, "id", $SeenArray));
Result:
Array
(
[2] => Array
(
[id] => 3
[name] => example3
)
)
$arr[] = array('title' => 'Overview');
$arr[] =array('title' => 'General');
$arr[] =array('title' => 'History');
$arr[] =array('title' => 'Construction');
$arr[] =array('title' => 'Plan');
$arr[] =array('title' => 'Other');
$info_arr[] = array("title" => "General", text => "value1");
$info_arr[] = array("title" => "History", text => "value1");
$info_arr[] = array("title" => "Construction", text => "value1");
$info_arr[] = array("title" => "Plan", text => "value1");
I need to be able merge these arrays together.So they look something like this. As I will need to loop thru the consolidated array. Other, Overview do not have any text values but still need to placed into the array.
$new_arr[] = array("title" => "General", text => "value1", "title" => "History", text => "value1", "title" => "Construction", text => "value1"
,"title" => "Plan", text => "value1","title" => "Overview", text => "","title" => "Other", text => "");
I have tried for loops (using count value), foreach loops, I thought array_intersect or array_diff don't see to solve the issue. This should not be so difficult, but I'm trying to piece together some really bad legacy code. Or the cube/florescent lights might have finally got to me.
Update:
while ($stmt->fetch()) {
$arr[] = array("title" => $Title);
}
and
while ($dstmt->fetch()) {
$info_arr[] = array("title" => $descriptionType, "descriptiontext" => $descriptionText); , "descriptiontext" => $val );
}
$dstmt & $stmt are queries.
I thought this would work but not so much
$r = array_intersect($arr, $info_arr);
var_dump($r);
Something like this Let me clarify:
$new_arr = array(array("title" => "General", text => "value1"),
array("title" => "History", text => "value1"),
array("title" => "Construction", text => "value1"),
array("title" => "Plan", text => "value1"),
array("title" => "Overview", text => ""),
array("title" => "Other", text => "")
);
If you want to work with these two arrays, you can just use the title as the key in $r.
foreach (array_merge($arr, $info_arr) as $x) {
$r[$x['title']]['title'] = $x['title'];
$r[$x['title']]['text'] = isset($x['text']) ? $x['text'] : '';
}
Or, you can go back a step and avoid having separate arrays by building the $r array in the same manner as you fetch your query results:
while ($stmt->fetch()) {
$r[$Title] = array('title' => $Title, 'text' => '');
}
while ($dstmt->fetch()) {
$r[$descriptionType] = array("title" => $descriptionType, "text" => $descriptionText);
}
Or, ideally, you could go back another step and avoid having separate queries by using a JOIN to get the same results in one query, but there's nothing in the question on which to base any specific suggestion for that.
As stated in the comments, the exact $new_arr you're requesting isn't possible. However, I think this will give you a similar result that should work for your purposes:
foreach ($info_arr as $infoArray) {
$found = array_search(array('title' => $infoArray['title']), $arr);
if (false !== false) {
unset($arr[$found]);
}
}
$new_arr = array_merge($info_arr, $arr);
It works by removing the "duplicates" from the original $arr before doing the array_merge().
If it's important to add an empty text value for the remaining items in $arr, do this before the array_merge():
foreach ($arr as &$arrArray) {
$arrArray['text'] = '';
}
The resulting array will look like this:
$new_arr[] = array(
array(
'title' => 'General',
'text' => 'value1',
),
array(
'title' => 'History',
'text' => 'value1',
),
array(
'title' => 'Construction',
'text' => 'value1',
),
array(
'title' => 'Plan',
'text' => 'value1',
),
array(
'title' => 'Overview',
'text' => '',
),
array(
'title' => 'Other',
'text' => '',
),
);
Suppose i have a array like this :
Array(
'1' => Array(
"ID" => 1,
"Name" => "name 1"
),
'2' => Array (
Array(
"ID" => 2,
"Name" => "name 2"
)
),
'3' => Array(
Array(
Array(
Array(
"ID" => 3,
"Name" => "name3"
)
)
),
'4' => Array (
Array {
"ID" => 4,
"Name" => "name 4"
),
Array(
"ID" => 5,
"Name" => "name 5"
),
Array(
"ID" => 6,
"Name" => "name 6"
)
);
number of sub-arrays is not ordered it may be 3, 4 or 5 etc...
and i wanted to get :
Array(
Array( "ID" => 1, "Name" => "name 1"),
Array( "ID" => 2, "Name" => "name 2"),
Array( "ID" => 3, "Name" => "name 3"),
Array( "ID" => 4, "Name" => "name 4"),
Array( "ID" => 5, "Name" => "name 5"),
Array( "ID" => 6, "Name" => "name 6"));
Is there an easy way to do this ?
EDIT :
Edited the above array to add :
'4' => Array (
Array {
"ID" => 4,
"Name" => "name 4"
),
Array(
"ID" => 5,
"Name" => "name 5"
),
Array(
"ID" => 6,
"Name" => "name 6"
)
);
which aren't nested but i still want them to be in my final array.
Thanks.
//Assuming your data is in $in
$out=array();
foreach($in as $k=>$v) {
while ((is_array($v)) && (isset($v[0]))) $v=$v[0];
//See below for next line
$out[]=$v;
}
print_r($out);
With the marked line being either $out[$k]=$v; or $out[]=$v; depending on wether you want to keep the 1st-level keys. In your desired output you do not ,so use the shown version
Edit
With you changed input array, you need to do something like
function addtoarray($inarray, &$outarray) {
foreach ($inarray as $i) {
if (!is_array($i)) continue;
if (isset($i['ID'])) $outarray[]=$i;
else addtoarray($i,$outarray);
}
}
$out=array();
addtoarray($in,$out);
print_r($out);
This was tested against your new input data
You could recurse through the array and check for the ID field.
function combine_array(array $src, array &$dest)
{
if( isset( $src['ID'] ) ) {
$dest[] = $src;
return;
}
foreach( $sub in $src ) {
combine_array( $sub, $dest );
}
}
Just wrote this off the top of my head, no testing, so it might have a few problems. But that's the basic idea.
This may work for you, assuming $array is the variable and php 5.3
//process
$array = array_map(function($block) {
$return = '';
foreach ($block as $sub) {
if (true === isset($sub['ID']) {
$return = $block;
break;
}
}
return $block;
}, $array);
array_filter($array); //remove empty elements
Wrote up a quick recursive function. You'll need to write any appropriate error handling and check the logic, since a discrepancy in your data could easily turn this into an infinite loop:
$output = array();
foreach ( $data as $d ) {
$output[] = loop_data( $d );
}
function loop_data( $data ) {
// Check if this is the right array
if( ! array_key_exists( "ID", $data ) ) {
// Go deeper
$data = loop_data( $data[0] );
}
return $data;
}
