How can I put out the following array?
$newdata = array (
'Spiel_ID' => $ausgabeT->Spielplan_ID,
'Heimmannschaft' => $ausgabeVereinT->Name,
'Gastmannschaft' => $ausgabeVereinTGast->Name
);
var_dump($newdata);
foreach($newdata as $result) {
echo $result['Spiel_ID'], '<br>';
}
For the echo I get error:
Illegal string offset 'Spiel_ID'
You are trying to echo a value that doesn't exist.
When you use foreach ($newdata as $result) the $result is a string, not an array.
You have two options, based on this structure:
$newdata = array (
'Spiel_ID' => $ausgabeT->Spielplan_ID,
'Heimmannschaft' => $ausgabeVereinT->Name,
'Gastmannschaft' => $ausgabeVereinTGast->Name
);
Option 1 — Display all values
foreach($newdata as $result) {
echo $result;
}
Option 2 — Display a single value
echo $newdata['Spiel_ID'];
Option 3 — Display Key + Value
foreach($newdata as $key => $value) {
echo $key . ' = ' . $value . '<br>';
}
All you need to do is just echo $result

I have a multi-dimensional array as follows:
Array
(
[lists] => Array
(
[0] => Array
(
[id] => 23ybdwhdwbed
[name] => TEST
(
[1] => Array
(
[id] => e223edsewed
[name] => TEST 2
(
)
)
I want to access the ID & name variables using a foreach loop.
I'm using this:
$x = 0;
foreach($lists as $list){
$listId = $list[$x]['id'];
$listName = $list[$x]['name'];
echo"$x | $listId $listName <br />";
$x++;
}
For some strange reason, I can only get the value of the first $listId & $name, not the second $listId or $name.
What am I doing wrong here?
You're assuming that you still need to provide the key for each child element. This is not the case.
try
foreach($lists as $list){
$listId = $list['id'];
$listName = $list['name'];
$listId $listName <br />";
}
the foreach() will iterate over them in turn.
if you do need the index number, do this instead.
foreach($lists as $x => $list){
where $x is the index.
The array you posted is wrong because it's missing closing ), so correct that (I think that is TYPO mistake)
After that you need to do it like below:-
foreach($lists['lists'] as $key=> $list){
$listId = $list['id'];
$listName = $list['name'];
echo "$key | $listId $listName <br />";
}
Output:-https://eval.in/846464
Or an one-liner code:-
foreach($lists['lists'] as $key=> $list){
echo "$key | ".$list['id']." ".$list['name']." <br />";
}
Output:-https://eval.in/846465
Your foreach iterates the first, not the second level of your multi dimensional array.
Since the first level only holds the lists array as one and only element the loop only executes once.
Pass the lists key to the foreach instead like so:
$x = 0;
foreach($lists['lists'] as $list) {
echo "$x | " . $list['id'] . " " . $list['name'] . "<br />";
++$x;
}
Also note how in here I reference the list elements by name to make it easier to read.
I think those numerical indexed will just confuse you so try this instead:
$my_array = array(array("id" => "23ybdwhdwbed", "name" => "TEST"), array("id" => "e223edsewed", "name" => "TEST 2"));
To access the values: use:
foreach($my_array as $my_data){
echo "ID:" . $my_data["id"];
echo "<br>";
echo "NAME:" .$my_data["name"];
echo "<br><br>";
}
you just need to do:
foreach($lists['list'] as $listKey=>$listValue){
$listId = $listValue['id'];
$listName = $listValue['name'];
echo"$listKey | $listId : $listName <br />";
}
Try this, I fixed your array structure to work, this is also dynamic so it does not matter how many array you have 0 -> above
$array = array(
'lists' => array(
'0' => array(
'id' => '23ybdwhdwbed',
'name' => 'TEST 1'
),
'1' => array(
'id' => 'e223edsewed',
'name' => 'TEST 2'
)
)
);
foreach ($array as $key => $value) {
for($ctr = 0; $ctr < count($value); $ctr++){
echo 'ID: ' . $value[$ctr]['id'] . '<br>';
echo 'Name: : ' . $value[$ctr]['name'] . '<br><br>';
}
}
I would like the data to be echoed out in this format
[0] - [name][description]
[1] - [name][description]
[2] - [name][description]
$options = array('guide_info' => $guide_info);
$guide_info = array( 'guide_name' => $guide_name,
'guide_description' => $guide_description
);
I created two foreach loops to try and echo out the name and description of each, like this:
foreach ($options as $key => $value) {
foreach ($guide_info as $type => $info){
$html .= $type . " " . $info . "\n";
}
}
but I receive errors about invalid argument supplied for foreach() on the second loop.
Currently my print_r($options) shows
Array ( [guide_name] => f
[guide_description] => fff
[0] => Array (
[guide_name] => fsss
[guide_description] => sssss
)
)
and my echo prints
guide_name fsss
guide_description sssss
guide_name fsss
guide_description sssss
guide_name fsss
guide_description sssss
How would I be able to echo out the correct information that print_r is showing?
Use a recursive function to echo out the name and description values in the desired format.
function process_array($arr, $counter){
foreach($arr as $key => $value){
if(is_array($value)){
process_array($value, ++$counter);
}else{
if($key == "guide_name"){
echo "[" . $counter . "] - [" . $value . "][";
}else{
echo $value . "]<br />";
}
}
}
}
// Here $options is your original array
process_array($options, 0);
Output:
[0] - [f][fff]
[1] - [fsss][sssss]
$guide_info = array( 'guide_name' => 'guid name',
'guide_description' => 'guid description',
);
$options = array('guide_info' => $guide_info);
foreach ($options as $key => $value) {
foreach($value as $a => $b) {
echo $a," =",$b ;
}
}
or for print_r
foreach ($options as $key => $value) {
print_r($value) ;
}
Why are you putting the $guide_info in $options.If you want all the entries from $guide_info, you can do this-
for($i = 0; $i < count($guide_info); $i++){
$html .= $type . " " . $info . "\n";
}
-> considering $guide_info is a multidimensional array like = array( [0] => 'guide_name' => $guide_name,
'guide_description' => $guide_description)
If for some reason $guide_info IS important, I would suggest it to be an indexed array not assoc.. Hope you find the solution :)
I have the following code which displays the results that I want. I'm trying to get it to sort on the key 'value' from the output below. So Eric, Eric 2, Eric 3
An example output of $resultnames is:
Array
(
[0] => Array
(
[Eric 2] => Asdf
)
[1] => Array
(
[Eric] => Asdf
)
[2] => Array
(
[Eric 3] => Asdf
)
)
So the key is the first name and the value of that key is the last name. I'm trying to sort the array by first name
foreach (array_chunk($uvugroups, 6, true) as $uvugroup)
{
foreach ($uvugroup as $uvustate) {
echo "<h4>Registrants</h4>";
$fnames = explode( '|', $uvustate['fname'] );
$lnames = explode( '|', $uvustate['lname'] );
$resultnames = array();
foreach ($fnames as $i => $key) {
$resultnames[] = array($key => $lnames[$i]);
}
foreach ($resultnames as $resultname) {
foreach ($resultname as $fkey => $lkey) {
echo "<ul>";
echo "<li>" . $fkey . " " . substr($lkey,0,1) . ".</li>";
echo "</ul>";
}
}
}
}
I tried to use ksort in different places in the code, but it didn't seem to have an effect.
It's a bit hard because the expected output is not defined in the question, but with this code as the contents of the second foreach it should produce a list sorted by first name.
$fnames = explode( '|', $uvustate['fname'] );
$lnames = explode( '|', $uvustate['lname'] );
$resultnames = array_combine($fnames, $lnames);
ksort($resultnames);
echo "<ul>";
foreach ($resultnames as $fkey => $lkey) {
echo "<li>" . $fkey . " " . substr($lkey,0,1) . ".</li>";
}
echo "</ul>";
I need some help reading the values from multidimension arrays. The array looks like below.
Array
(
[translations] => Array
(
[0] => Array
(
[translatedText] => fantasma
[detectedSourceLanguage] => en
)
)
)
I tried the following, but kept on getting blanks. Any help be appreciated?
foreach($item as $translations)
{
foreach($row['0'] as $k)
{
echo $k['translatedText'];
echo $k['detectedSourceLanguage'];
}
}
When working with foreach loops, you want to call the array you plan on iterating over with the following syntax:
foreach($array as $variable){ }
Array being the array you plan on going through, and the variable being the variable you are planning to call it as within the foreach.
More information on foreach loops can be found at PHP:foreach
With that said, try the code below:
$data = array(
"translations" => array(
array("translatedText" => "fantasma",
"detectedSourceLanguage" => "en"
)
)
);
echo "<pre>";
echo print_r($data);
echo "</pre>";
foreach($data["translations"] as $translation) {
echo $translation['translatedText'] . "<br />";
echo $translation['detectedSourceLanguage'] . "<br />";
}
//Or, if the $data variable will be holding multiple translation arrays:
foreach($data as $d) {
foreach($d as $translation){
echo $translation['translatedText'];
echo $translation['detectedSourceLanguage'];
}
}
Try this:
foreach ($item['translations'] as $translation) {
echo $translation['translatedText'];
echo $translation['detectedSourceLanguage'];
}
See DEMO
Change your code to below :
$test = Array(
"translations" => Array (
"0" => Array (
"translatedText" => "fantasma",
"detectedSourceLanguage" => "en"
)
)
);
foreach ($test as $translations) {
foreach ($translations as $k) {
echo $k["translatedText"];
echo "<br/>";
echo $k["detectedSourceLanguage"];
}
}
This should work.
Follow this for more info about array : http://php.net/manual/en/language.types.array.php
The issue is that you are not defining the $row variable. The good news is that you don't need it.
You can simply do this:
foreach($item as $translations => $values)
{
foreach($values as $k)
{
echo $k['translatedText']."\n";
echo $k['detectedSourceLanguage'];
}
}
This question already has answers here:
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/>';
}
?>
