Looping the array in select - php

Question

I have this kind of array shown in Picture. How can i insert the values in the select option as
<option value="7">7</option>
<option value="13000">13000</option>
<option value="19AAAAA">19AAAAA</option>
<option value="sdsdas">sdsdas</option>
<option value="dasdasdasd">dasdasdasd</option>

Answer 1

Simply flatten the multi-dimensional array, and then loop through it.
Suppose $arr in your original multi-dimensional array
$it = new RecursiveIteratorIterator(new RecursiveArrayIterator($arr));
foreach($it as $value){
?>
<option value="<?php echo $value; ?>"><?php echo $value; ?></option>
<?php
}
Here are the relevant references:

Answer 2

<?php
foreach($arr as $val){
foreach($val as $val2){
foreach($val2 as $val3){ ?>
<option value="<?php echo $val3;?>"><?php echo $val3 ;?></option><?php
}
}
}
?>

Answer 3

You need to flat array. You can do it with recursive function. Here you have general function for that.
/**
* Get multilevel array convert to single-level array
* #param $array
* #return array
*/
function getFlattened($array) {
$flattened = [];
foreach ($array as $flat) {
if (is_array($flat)) {
$flatArray = array_merge($flatArray, getFlattened($flat));
} else {
$flattened[] = $flat;
}
}
return $flattened;
}
Of course you can use that approach to recursively display select - not only to flat array.

Answer 4

<?php foreach($array as $inner): ?>
<?php foreach($inner as $innerTwo): ?>
<?php foreach($innerTwo as $item): ?>
<option value="<?= $item ?>"><?= $item ?></option>
<?php endforeach; ?>
<?php endforeach; ?>
<?php endforeach; ?>

Answer 5

you may try this.
<?php
$input = Array(
Array
(
0 => 7,
1 => 13000
),
Array
(
0 => '19AAAAA',
1 => 'sdsdas'
)
);
$options = "";
$result = call_user_func_array("array_merge", $input);
for($i = 0;$i< count($result);$i++ ){
$options .="<option value='".$result[$i]."'>".$result[$i]."</option>";
}
echo $options;
