<?php
$categories = [
133 => 'Siomay',

How to get id categories? The example shown
Results:
133
123
20
-1 // Miss (-1)
To get the IDs in a loop:
foreach($categories as $key=>$value)
{
echo $key . "<br />";
}
That will output
133
123
20
I assume you should show -1 when there is no appropriate value? If it's all about, try this:
<?php
$categories = [
133 => 'Siomay',
123 => 'Indonesian',
20 => 'Bento',
];
$input_categories = [
'Siomay',
'Indonesian',
'Bento',
'Yoghurt',
];
foreach($input_categories as $input_category)
{
if(in_array($input_category, $categories))
echo array_search($input_category, $categories).'<br/>';
else
echo '-1<br/>';
}
Output:
133
123
20
-1
You can use array_keys() method for this. like below:
$ids = array_keys($categories);
echo "<pre>";
print_r($ids);
foreach ( $categories as $k => $v ) {
echo $k; echo "<br/>";
}
if you wants to get category id which exits in $input_category then user this
$flipped = array_flip($categories);
foreach ( $input_categories as $v ) {
echo $flipped[$v]; echo "<br/>";
}

I have a multidimensional array which has keys and key has values or have another array with keys and values so I want to search by keys but in input like 230 is user input
and it will go to 3 then 4 then 1 if result is a value but not an array it must print the value like
input = 230 result should be = "3-4-1"
so I need to str_split the number and search it 1 by 1 if first number is array then look for second kinda
edit1 = I found the way to split the key
//edit1
$keys = "021";
$keysSplit =str_split($keys, strlen($keys)/strlen($keys));
echo $keys[0];
//edit 1 ends
$arr = [0 => [0=>"1-1", 1 => "1-2" , 2=>"1-3", 3=>[0=>"1-4-1", 1 => "1-4-2" , 2=>"1-4-3"]],
1 => [0=>"2-1", 1 => "2-2" , 2=>"2-3"],
2 => [0=>"3-1", 1 => "3-2" , 2=>"3-3", 3=>[0 =>"3-4-1" , 1=> "3-4-2"]],
];
$keys = "021";
function searchByKey($array , $keys){
$result = [];
$keys = "021";
$keys =str_split($keys, strlen($keys)/strlen($keys));
$key1 = $keys[0];
$key2 = $keys [1];
$key3 = $keys [2];
foreach ($array as $key1 => $value){
if (is_array($value)){
$key1 = null;
$key1 = $key2;
$key2 = $key3;
return searchByKey($value , $key1);
}
else {
$result=$value;
echo $result;
}
}
}
$arr = searchByKey($arr, $keys);
The function only works as key and value given and it will print every key and value on the key it asked first so its not the thing I wanted to do could anyone help and explain?
Answer given by #Anggara I made it in to function ;
$input = "11";
function searchByNumber($array, $input){
$result = $array;
for ($i = 0; $i < strlen($input); $i++) {
if (is_array($result)) {
$result = $result[$input[$i]];
} else {
$result = "Does not exists";
break;
}
}
echo $result;
}
$arr = searchByNumber($arr, $input);
You can access char in string like accessing an array. For example:
$input = "230";
// $input[0] is "2"
// $input[1] is "3"
// $input[2] is "0"
So my approach is to loop for each character in input key, and look for corresponding value in $arr. Each iteration will set found array element into variable $result. If the searched key does not exist (ex: "021"), print error message.
<?php
$arr = [
0 => [
0 => "1-1",
1 => "1-2",
2 => "1-3",
3 => [
0 => "1-4-1",
1 => "1-4-2",
2 => "1-4-3"
]
],
1 => [
0 => "2-1",
1 => "2-2",
2 => "2-3"
],
2 => [
0 => "3-1",
1 => "3-2",
2 => "3-3",
3 => [
0 => "3-4-1",
1 => "3-4-2"
]
],
];
$input = "230";
$result = $arr;
for ($i = 0; $i < strlen($input); $i++) {
if (is_array($result)) {
$result = $result[$input[$i]];
} else {
$result = 'Can not traverse path';
break;
}
}
echo $result;
After splitting the keys
for($i=0;$i<strlen($keys);$i++){
$arr = $arr[$keys[$i]];
}
if(is_array($arr)){
echo json_encode($arr);
}else{
echo $arr;
}
You need a loop, which will go through the keys one by one and assigning into the array.
$products = Array ( [products] => Array ( [0] => 12,11,10 [1] => 16,15,14 [2] => 600,103,20 ) );
foreach($products as $k=>$v)
{
$product_id = $v[0];
$product_weight_id = $v[1];
$product_quantity = $v[2];
}
output required like:
12 16 600
11 15 103
10 14 20
current output :
12,11,10 16,15,14 600,103,20
Update:
If you want to generate a different output, next example may help:
PHP:
<?php
$products = array(
'12,11,10',
'16,15,14',
'600,103,20'
);
$output = array();
foreach($products as $product) {
$a = explode(',', $product);
foreach ($a as $key => $value) {
$output[$key][] = $value;
}
}
foreach($output as $line) {
echo implode(' ', $line)."<br>";
}
?>
Output:
12 16 600
11 15 103
10 14 20
Original answer:
Next example demonstrates two possible approaches to get an output from your array.
PHP:
<?php
$products = array(
'12,11,10',
'16,15,14',
'600,103,20'
);
// Complex approach
foreach($products as $product) {
$a = explode(',', $product);
foreach ($a as $value) {
echo $value." ";
}
echo "<br>";
}
// Simple approach
foreach($products as $product) {
echo $product."<br>";
}
?>
Output:
12 11 10
16 15 14
600 103 20
12,11,10
16,15,14
600,103,20
Please see below code.
$products = array (
'0' => '12,11,10',
'1' => '16,15,14',
'2' => '600,103,20'
);
$productIds = array();
$productWeights = array();
$productQuantities = array();
foreach( $products as $k => $v ) {
$line = explode(',', $v );
$productIds[] = $line[0];
$productWeights[] = $line[1];
$productQuantities[] = $line[2];
}
echo implode( ' ', $productIds);
echo '<br />';
echo implode( ' ', $productWeights);
echo '<br />';
echo implode( ' ', $productQuantities);
echo '<br />';
Using array_map() and implode() you can do it easily. Example:
$products = [[12,11,10], [16,15,14], [600,103,20]];
echo implode('<br />', array_map(function ($arr) { return implode(' ', $arr); }, $products));
Working demo.
I have this some arrays that look like this,
$array = Array(
'Homer' => Array
(
'id' => 222,
'size' => 12
),
'Bart' => Array
(
'id' => 333,
'size' => 3
)
);
I would like to echo Homer: id is 222, size is 12
then in the next line echo Bart: id is 333, size is 3 using a foreach loop as key and values.
So i basically want to echo all the Simpsons character names which have their id and size next their names.
I tired this but it printed homer too many times and it even used Bart's id and size at one point.
foreach( $array as $billdate => $date) {
foreach( $date as $k => $v) {
echo $billdate; // Prints Homer and bart
foreach($array as $innerArray){
foreach($innerArray as $key => $value){
echo "[". $key ."][". $value ."] <br/>";
}}
}
}
Thanks in advance.
you can try like this:
foreach( $array as $billdate => $date) {
echo $billdate.': id is '.$date['id'].', size is '.$date['size'];
}
Don't use so many foreach ,just think your need loop ...
foreach( $array as $billdate => $date) {
echo $billdate; // Prints Homer and bart
foreach($date as $key => $value){
echo "[". $key ."][". $value ."] <br/>";
}
}
I have an array that looks like this:
$rowarray(
[0] => [PID] => 97162 [TID] => 340 [StatsID] => 49678
[1] => [PID] => 97165 [TID] => 340 [StatsID] => 49673
[2] => [PID] => 97167 [TID] => 340 [StatsID] => 49675
[3] => [PID] => 97162 [TID] => 340 [StatsID] => 49679
)
Then my code looks like this:
$cntr=0;
foreach($rowarray as $row)
{
echo "<tr><td>$row[PID] $row[TID] $row[StatsID] </td></tr>";
$cntr++;
}
Two things I want to do I want to be able not print the duplicates in the array but print the additional column that has a different value. So my desired output would look like this.
97162 340 49678 49679
97165 340 49673
97167 340 49675
I started out with the array_unique() but that only returned:
97162 340 49678
Assuming only the StatsID changes (not clear from the question)
$map = array();
foreach($rowarray as $row){
$k = $row["PID"] . '-' . $row["TID"];
if( !isset( $map[$k] ) ){
$map[$k] = array();
}
array_push( $map[$k], $row["StatsId"] );
}
foreach($map as $k=>$v){
$row = explode( '-', $k );
echo "<tr><td>$row[0] $row[1] " . implode( " ", $v ) . " </td></tr>";
}
Here's what I'd do:
Start by sorting the array (using usort to sort by PID, then by TID)
Initialize "last" variables ($last_PID and $last_TID). They will store the respective values in the loop
In the loop, first compare the "current" variables to the "last" ones, if they're the same then just echo the StatsID value.
If they're not the same, output the <tr> (but not the final </tr>, so the first part of the loop can add more StatsID values if necessary)
Still inside the loop, after outputting everything, update the "last" variables.
After the loop, output the final </tr>
This may not be optimal, but I'm pretty sure it'll work.
Transfer the $rowarray structure into a map of maps of arrays, like this:
$rowarray = array(
array('PID' => 97162, 'TID' => 340, 'StatsID' => 49678),
array('PID' => 97165, 'TID' => 340, 'StatsID' => 49673),
array('PID' => 97167, 'TID' => 340, 'StatsID' => 49675),
array('PID' => 97162, 'TID' => 340, 'StatsID' => 49679)
);
$keys = array();
foreach ($rowarray as $row) {
if (!is_array(#$keys[$row['TID']])) {
$keys[$rowarray['TID']] = array();
}
if (!is_array(#$keys[$row['TID']][$row['PID']])) {
$keys[$row['TID']][$row['PID']] = array();
}
$keys[$row['TID']][$row['PID']][] = $row['StatsID'];
}
foreach ($keys as $pid => $pid_arr) {
foreach ($pid_arr as $tid => $tid_arr) {
echo "<tr><td>$tid $pid " . implode(' ', $tid_arr) . "</td></tr>";
}
}
See this code in action
As far as I can tell, the only way to do this would be to loop through the array creating a new unique array as you go.
$unique = array();
foreach ($row as $value)
{
$key = $value['PID'];
if (isset($unique[$key]))
{
$unique[$key]['StatsID'] .= ' ' . $value['StatsID'];
}
else
{
$unique[$key] = $value;
}
}
Now, $unique would give you the results you're looking for and you can loop through the unique array and output your results (I also added your counter if needed):
$count = count($unique);
foreach ($unique as $row)
{
echo "<tr><td>{$row['PID']} {$row['TID']} {$row['StatsID']} </td></tr>";
}

Is there a pretty print for PHP?

Closed 7 months ago.
Here is the code for pulling the data for my array
<?php
$link = mysqli_connect('localhost', 'root', '', 'mutli_page_form');
$query = "SELECT * FROM wills_children WHERE will=73";
$result = mysqli_query($link, $query) or die(mysqli_error($link));
if ($result = mysqli_query($link, $query)) {
/* fetch associative array */
if($row = mysqli_fetch_assoc($result)) {
$data = unserialize($row['children']);
}
/* free result set */
mysqli_free_result($result);
}
?>
When I use print_r($data) it reads as:
Array ( [0] => Array ( [0] => Natural Chlid 1 [1] => Natural Chlid 2 [2] => Natural Chlid 3 ) )
I would like it to read as:
Natural Child 1
Natural Child 2
Natural Child 3
Instead of
print_r($data);
try
print "<pre>";
print_r($data);
print "</pre>";
print("<pre>".print_r($data,true)."</pre>");
I have a basic function:
function prettyPrint($a) {
echo "<pre>";
print_r($a);
echo "</pre>";
}
prettyPrint($data);
EDIT: Optimised function
function prettyPrint($a) {
echo '<pre>'.print_r($a,1).'</pre>';
}
EDIT: Moar Optimised function with custom tag support
function prettyPrint($a, $t='pre') {echo "<$t>".print_r($a,1)."</$t>";}
Try this:
foreach($data[0] as $child) {
echo $child . "\n";
}
in place of print_r($data)
I think that var_export(), the forgotten brother of var_dump() has the best output - it's more compact:
echo "<pre>";
var_export($menue);
echo "</pre>";
By the way: it's not allway necessary to use <pre>. var_dump() and var_export() are already formatted when you take a look in the source code of your webpage.
if someone needs to view arrays so cool ;) use this method.. this will print to your browser console
function console($obj)
{
$js = json_encode($obj);
print_r('<script>console.log('.$js.')</script>');
}
you can use like this..
console($myObject);
Output will be like this.. so cool eh !!
foreach($array as $v) echo $v, PHP_EOL;
UPDATE: A more sophisticated solution would be:
$test = [
'key1' => 'val1',
'key2' => 'val2',
'key3' => [
'subkey1' => 'subval1',
'subkey2' => 'subval2',
'subkey3' => [
'subsubkey1' => 'subsubval1',
'subsubkey2' => 'subsubval2',
],
],
];
function printArray($arr, $pad = 0, $padStr = "\t") {
$outerPad = $pad;
$innerPad = $pad + 1;
$out = '[' . PHP_EOL;
foreach ($arr as $k => $v) {
if (is_array($v)) {
$out .= str_repeat($padStr, $innerPad) . $k . ' => ' . printArray($v, $innerPad) . PHP_EOL;
} else {
$out .= str_repeat($padStr, $innerPad) . $k . ' => ' . $v;
$out .= PHP_EOL;
}
}
$out .= str_repeat($padStr, $outerPad) . ']';
return $out;
}
echo printArray($test);
This prints out:
[
key1 => val1
key2 => val2
key3 => [
subkey1 => subval1
subkey2 => subval2
subkey3 => [
subsubkey1 => subsubval1
subsubkey2 => subsubval2
]
]
]
print_r() is mostly for debugging. If you want to print it in that format, loop through the array, and print the elements out.
foreach($data as $d){
foreach($d as $v){
echo $v."\n";
}
}
This may be a simpler solution:
echo implode('<br>', $data[0]);
This tries to improve print_r() output formatting in console applications:
function pretty_printr($array) {
$string = print_r($array, TRUE);
foreach (preg_split("/((\r?\n)|(\r\n?))/", $string) as $line) {
$trimmed_line = trim($line);
// Skip useless lines.
if (!$trimmed_line || $trimmed_line === '(' || $trimmed_line === ')' || $trimmed_line === 'Array') {
continue;
}
// Improve lines ending with empty values.
if (substr_compare($trimmed_line, '=>', -2) === 0) {
$line .= "''";
}
print $line . PHP_EOL;
}
}
Example:
[activity_score] => 0
[allow_organisation_contact] => 1
[cover_media] => Array
[image] => Array
[url] => ''
[video] => Array
[url] => ''
[oembed_html] => ''
[thumb] => Array
[url] => ''
[created_at] => 2019-06-25T09:50:22+02:00
[description] => example description
[state] => published
[fundraiser_type] => anniversary
[end_date] => 2019-09-25
[event] => Array
[goal] => Array
[cents] => 40000
[currency] => EUR
[id] => 37798
[your_reference] => ''
I assume one uses print_r for debugging. I would then suggest using libraries like Kint. This allows displaying big arrays in a readable format:
$data = [['Natural Child 1', 'Natural Child 2', 'Natural Child 3']];
Kint::dump($data, $_SERVER);
One-liner for a quick-and-easy JSON representation:
echo json_encode($data, JSON_PRETTY_PRINT);
If using composer for the project already, require symfony/yaml and:
echo Yaml::dump($data);
echo '<pre>';
foreach($data as $entry){
foreach($entry as $entry2){
echo $entry2.'<br />';
}
}
<?php
//Make an array readable as string
function array_read($array, $seperator = ', ', $ending = ' and '){
$opt = count($array);
return $opt > 1 ? implode($seperator,array_slice($array,0,$opt-1)).$ending.end($array) : $array[0];
}
?>
I use this to show a pretty printed array to my visitors
Very nice way to print formatted array in php, using the var_dump function.
$a = array(1, 2, array("a", "b", "c"));
var_dump($a);
I use this for getting keys and their values
$qw = mysqli_query($connection, $query);
while ( $ou = mysqli_fetch_array($qw) )
{
foreach ($ou as $key => $value)
{
echo $key." - ".$value."";
}
echo "<br/>";
}
I would just use online tools.
first do print_r(your_array)
Second copy the result and paste in http://phillihp.com/toolz/php-array-beautifier/
For single arrays you can use implode, it has a cleaner result to print.
<?php
$msg = array('msg1','msg2','msg3');
echo implode('<br />',$msg);
echo '<br />----------------------<br/>';
echo nl2br(implode("\n",$msg));
echo '<br />----------------------<br/>';
?>
For multidimensional arrays you need to combine with some sort of loop.
<?php
$msgs[] = $msg;
$msgs[] = $msg;
$msgs[] = $msg;
$msgs[] = $msg;
$msgs[] = $msg;
foreach($msgs as $msg) {
echo implode('<br />',$msg);
echo '<br />----------------------<br/>';
}
?>
