My array is like:
Array
(
[0] => Array
(
[id] => 6
[name] => Name1
)
[1] => Array
(
[id] => 7
[name] => Name2
)
)
How can I check any perticular value of name exists in this multi-dimentional array?
function checkName($haystack, $needle) {
foreach($haystack as $hay) {
if($hay['name'] == $needle) {
return true;
}
}
return false;
}
Iterate.
function multi_in_array($name, $array) {
foreach ($array as $sub_array) {
if (in_array($name, $array)) {
return true;
}
}
return false;
}
With that structure, your only option is essentially a linear search:
$found = null;
foreach ($arr as $idx => $elem) {
if ($elem['name'] == $searchName) {
$found = $idx;
}
}
if ($found !== null) {
echo "Found $searchName at $idx.";
}
This function will help you,
<?php
function multi_dim_array_search($array,$col,$val)
{
foreach($array as $elem)
if($elem[$col] == $val)
return true;
return false;
}
$array = array(
array('id' => 1,'name' => 'Name1'),
array('id' => 2,'name' => 'Name2')
);
//usage
var_dump(multi_dim_array_search($array,'name','Name1')); //true
var_dump(multi_dim_array_search($array,'name','Name2')); //true
var_dump(multi_dim_array_search($array,'name','Name3')); //false
?>
