This class method can search in multidimensional array by multiple conditions:
<?php
$data = array(
array('foo' => 'test4', 'bar' => 'baz'),
array('foo' => 'test', 'bar' => 'baz'),
array('foo' => 'test1', 'bar' => 'baz3'),
array('foo' => 'test', 'bar' => 'baz'),
array('foo' => 'test', 'bar' => 'baz4'),
array('foo' => 'test4', 'bar' => 'baz1'),
array('foo' => 'test', 'bar' => 'baz1'),
array('foo' => 'test3', 'bar' => 'baz2'),
array('foo' => 'test', 'bar' => 'baz'),
array('foo' => 'test', 'bar' => 'baz'),
array('foo' => 'test4', 'bar' => 'baz1')
);
class Stdlib_Array
{
public static function multiSearch(array $array, array $pairs)
{
$found = array();
foreach ($array as $aKey => $aVal) {
$coincidences = 0;
foreach ($pairs as $pKey => $pVal) {
if (array_key_exists($pKey, $aVal) && $aVal[$pKey] == $pVal) {
$coincidences++;
}
}
if ($coincidences == count($pairs)) {
$found[$aKey] = $aVal;
}
}
return $found;
}
}
$result = Stdlib_Array::multiSearch($data, array('foo' => 'test4',
'bar' => 'baz1'));
var_dump($result);
?>
Will produce:
array(2) {
[5]=>
array(2) {
["foo"]=>
string(5) "test4"
["bar"]=>
string(4) "baz1"
}
[10]=>
array(2) {
["foo"]=>
string(5) "test4"
["bar"]=>
string(4) "baz1"
}
}
