I have following arrays :
<?php
$a=array(
"abc"=>array("red","white","orange"),
"def"=>array("green","vilot","yellow"),
"xyz"=>array("blue","dark","pure")
);
echo array_search(array("dark"),$a);
?>
How to get output of xyz in array list.
array_search returns false or the key. Since you have multiple dimensions you must loop through to get the lowest level.
Since we are in another dimension your return will actually be 1. For this reason, if array_search succeeds we must use the key that is defined in the foreach
<?php
$a=array("abc"=>array("red","white","orange"),"def"=>array("green","vilot","yellow"),"xyz"=>array("blue","dark","pure"));
foreach($a as $key=>$data){
if(array_search("dark",$data)){
echo $key;
}
}
Outputs: xyz
You can create one user-define function to check value
$a=array("abc"=>array("red","white","orange"),"def"=>array("green","vilot","yellow"),"xyz"=>array("blue","dark","pure"));
function search_data($value, $array) {
foreach ($array as $key => $val) {
if(is_array($val) && in_array($value,$val))
{
return $key;
}
}
return null;
}
echo search_data("dark",$a);
Please try this
function searchMultiArray($arrayVal,$val){
foreach($arrayVal as $key => $suba){
if (in_array($val, $suba)) {
return $key;
}
}
}
$a = array("abc"=>array("red","white","orange"),"def"=>array("green","vilot","yellow"),"xyz"=>array("blue","dark","pure"));
echo $keyVal = searchMultiArray($a , "dark");
