multidimensional array find the given value in array in php - php

Question

Array
Array (
[0] => Array (
[0] => Array ( [planoption_id] => 1 )
[1] => Array ( [planoption_id] => 2 )
[2] => Array ( [planoption_id] => 3 )
[3] => Array ( [planoption_id] => 4 )
[4] => Array ( [planoption_id] => 5 )
[5] => Array ( [planoption_id] => 6 )
[6] => Array ( [planoption_id] => 7 )
[7] => Array ( [planoption_id] => 53 )
[8] => Array ( [planoption_id] => 1 )
[9] => Array ( [planoption_id] => 2 )
)
)
how to find the value in givene array.above array is $arraypush ?
if (in_array('2', $arraypush)) {
echo "INCLUDED";
} else {
echo "-";
}
How can i do this ?

Answer 1

This should work for all multidimensional arrays :
function findInArray($array, $value){
foreach($array as $k=>$v){
if((is_array($v) && findInArray($v, $value)) || ($v == $value)){
return "INCLUDED";
}
}
return false;
}

I think you want like this:-
<?php
$arraypush = Array ( 0 => Array ( 0 => Array ( 'planoption_id' => 1 ), 1 => Array ( 'planoption_id' => 2 )));
echo "<pre/>";print_r($arraypush);
foreach($arraypush as $key=>$value){
foreach($value as $key1=>$val){
if(in_array('2', $val) == true){
echo "value exist at the initial array [".$key.']['.$key1.'] index and is INCLUDED.';
}
}
}
?>

The in_array() function in your code is searching for the data in $arraypush and the data is in $arraypush[0]
And you can't compare a value with a array in in_array() function, in yor array the 'needle' isn't a value, is an array so you have to make an array who gets the value in a format comparable whit the array you have
$arraypush = array(
0 => array(
0 => array( 'planoption_id' => 1 ),
1 => array( 'planoption_id' => 2 ),
2 => array( 'planoption_id' => 3 ),
3 => array( 'planoption_id' => 4 ),
4 => array( 'planoption_id' => 5 ),
5 => array( 'planoption_id' => 6 ),
6 => array( 'planoption_id' => 7 ),
7 => array( 'planoption_id' => 53 ),
8 => array( 'planoption_id' => 1 ),
9 => array( 'planoption_id' => 2 )
)
);
//gettig the value for the search
$foo = $_GET['foo'];
// making the 'needle' in a array format like your array definition
$foo_array = array('planoption_id' => $foo);
//use in_array() for search your array-needle
//in the $arraypush[0] where is the data, not in $arraypush only
if(in_array($foo_array, $arraypush[0]))
{
die($foo);
}
else
{
die("-");
}

Try this I think is help full to you.
<?php
$a = array (
0 => array (
0 => array ( 'planoption_id' => 1 ),
1 => array ( 'planoption_id' => 2 ),
2 => array ( 'planoption_id' => 3 ),
3 => array ( 'planoption_id' => 4 ),
4 => array ( 'planoption_id' => 5 ),
5 => array ( 'planoption_id' => 6 ),
6 => array ( 'planoption_id' => 7 ),
7 => array ( 'planoption_id' => 53 ),
8 => array ( 'planoption_id' => 1 ),
9 => array ( 'planoption_id' => 2 ),
)
);
function multi_in_array($value, $array)
{
foreach ($array AS $item)
{
if (!is_array($item))
{
if ($item == $value)
{
//return true;
echo "INCLUDED";
}
continue;
}
if (in_array($value, $item))
{
//return true;
echo "INCLUDED";
}
else if (multi_in_array($value, $item))
{
//return true;
echo "-";
}
}
//return false;
echo "-";
}
echo multi_in_array(2, $a);
Output:- -INCLUDED-------INCLUDED--

The following even works for arrays of arbitrary dimensions:
$found = false;
$needle = 2;
$it = new RecursiveIteratorIterator(new RecursiveArrayIterator($array));
foreach($it as $v) {
if ($v == $needle) {
$found = true;
break;
}
}
echo $found ? 'INCLUDED' : '-';
