Replace a String in array php - php

Question

I have an array named $info. I want to replace string "YES" found wherever within the array with space or empty string.How can it be done?
Below is the code:
<?php
$conn = mysql_connect("localhost" , "root" , "") or die("Can not connect." . mysql_error());
$db = mysql_select_db("leothian" , $conn) or die("Can not connect." . mysql_error());
$selTable = "select * from dump_hotelbasicinfo ORDER BY id ASC LIMIT 5";
$resultTable = mysql_query($selTable,$conn);
while($rowTable = mysql_fetch_array($resultTable))
{
$selQuery = "SELECT * FROM dump_hotelamenities WHERE HotelCode='$rowTable[HotelCode]' LIMIT 5";
$resultQuery = mysql_query($selQuery);
while($row=mysql_fetch_array($resultQuery))
{
echo "<br> Hotel Code : " .$row['HotelCode'];
$info = array();
$info = (explode(';',$row['PAmenities']));
echo array_search("YES",$info);
echo "<br> Hotel Features : " ;
print_r( $info);
echo "<hr>";
}
}
?>
OUTPUT :
Hotel Features : Array ( [0] => Small pets allowed under 5 kg [1] => YES Small pets allowed under 5 kg [2] => Large pets allowed over 5 kg [3] => YES Large pets allowed over 5 kg [4] => Wheelchair-accessible [5] => YES Wheelchair-accessible [6] => Car park [7] => YES Car park [8] => Garage [9] => YES Garage [10] => Mobile phone coverage [11] => Wired Internet [12] => Wi-fi [13] => Transfer service [14] => Secure parking [15] => Room service [16] => Laundry service [17] => Hotel safe [18] => Cloakroom [19] => Lift access [20] => Newspaper stand [21] => Supermarket [22] => Bicycle storage [23] => Sun terrace [24] => Gym [25] => Newspapers [26] => Restaurant [27] => Non-smoking area [28] => Photocopier [29] => Sun loungers [30] => Children& [31] => apos [32] => s play area [33] => TV lounge [34] => Sauna [35] => Massage [36] => Spa treatments [37] => Year of construction - 2008 [38] => Number of floors main building - 10 [39] => Apartments - 25 [40] => Studios - 1 [41] => Connecting rooms [42] => YES Connecting rooms [43] => Apartment complex [44] => Nearest Bus / Metro Stop - 25000 m [45] => Ski slopes - 2000 m )

Answer 1

A for each loop would work
foreach($info as $k=>$v)
$info[$k] = str_replace('YES','',$v);

Answer 2

<?php
$array = array('this','is','a','test','yes it is','YES it is');
$array = array_map(function($item){
$item = str_replace('YES','', $item);
return $item;
}, $array);
var_dump($array);

Answer 3

function customSearch($keyword, $arrayToSearch){
foreach($arrayToSearch as $key => $arrayItem){
if( stristr( $arrayItem, $keyword ) ){
$arrayToSearch[key] = "yes";
return $key;
}
}
}
I haven't actually tried this but please Refer to this question here if my code is a bit off:
