If I have the following array
$arrays = $cdo->rows();
Array
(
[0] => Array
(
[0] => what is the name of you ?
[1] => Reham
)
[1] => Array
(
[0] => Where did you came from ?
[1] => earth
)
)
Using PHP language how can i print this like a question and answer
My try since Iam not good in PHP was
foreach ($arrays as $arr){
//print_r($arr);
foreach (arr as $a){
echo $a . "<br />";
}
}
But results like
what is the name of you ?
Reham
Where did you came from ?
earth
So I'm unable to know where is the question and where is the answer, as I'm going to insert it into database so am i supposed to something like
foreach ($arrays as $arr){
//print_r($arr);
foreach (arr as $q => $a){
echo "Question : " . $q . " | Answer : " . $a . "<br />";
}
}
I don't think I fully understood what you want. Is this what you are looking for?
$array = [
[
'what is the name of you ?',
'Reham'
],
[
'Where did you came from ?',
'earth'
]
];
foreach($array as $arr) {
echo $arr[0] . '<br>' . $arr[1] . '<br>';
}
Let me know if this is what you want.
Your array is not really good to deal with, it's only an indexed array, you should use a multidimensional.
But you can just use indexes :
foreach ($arrays as $arr) {
echo $arr[0]; // question
echo $arr[1]; // answer
}

Say I have this PHP array()
$tour_from array
Array
(
[0] => Array
(
[0] => Dhaka
[1] => noakhali
)
[1] => Array
(
[0] => Chittagong
[1] => Sylhet
)
)
I want to make like this:
Dhaka - Noakhali
Chittagong - Sylhet
How can I do this?
I used this but it's the wrong way:
foreach ($tour_from as $key => $value) {
$chunk = array_chunk($value, 2);
foreach ($chunk as $key1 => $value1) {
echo $value1[$key][$key1] . ' - ' . $chunk[$key][$key1];
echo '<br/>';
}
}
I think you're overcomplicating it a bit. Why not just loop over the outer array and implode the inner array?
<?php
$tour_from = [
['Dhaka', 'Noakhali'],
['Chittagong', 'Sylhet'],
];
foreach ($tour_from as $elem) {
print implode(' - ', $elem);
print '<br>';
}
There is no need for chunking or a second loop.
One loop containing implode() will do.
Code: (Demo)
$tour_from = [
['Dhaka', 'Noakhali'],
['Chittagong', 'Sylhet']
];
foreach ($tour_from as $row) {
echo implode(' - ', $row), "\n";
}
Output:
Dhaka - Noakhali
Chittagong - Sylhet
Alternatively, if you like a functional one-liner: (Demo)
echo implode("<br>", array_map(function($row){ return implode(' - ', $row); }, $tour_from));
*The advantage to this is there is no trailing <br> on the final imploded string.
Or with fewer function calls, here is a version with array_reduce(): (Demo)
echo array_reduce($tour_from, function($carry, $row) {
return $carry .= ($carry !== null ? "<br>\n" : '') . $row[0] . ' - ' . $row[1];
});
If you want to avoid using foreach you can do the same thing with array_walk and pass by reference &$var.
$array = [
["Dhaka", "noakhali"],
["Chittagong", "Sylhet"]
];
array_walk($array, function(&$item){
$item = implode(' - ', $item);
});
print_r($array);
Output:
Array
(
[0] => Dhaka - noakhali
[1] => Chittagong - Sylhet
)
Sandbox
If you want to output it instead of modify the array you can just echo it instead or do something like implode('<br>', $array) afterwords.
OH, Yes, I found the way:
foreach ($tour_from as $key => $value) {
$chunk = array_chunk($value, 2);
foreach ($chunk as $key1 => $value1) {
echo implode(' - ', $value1);
echo '<br/>';
}
}
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 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?
(31 answers)
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/>';
}
?>
