I have a multidimensional array below. And I am trying to get certain part of the array based on a value that is passed into the function. But for some reason it returns false even though the path matches, it only return something if /test is used but if I type /hello the if fails and it returns false.
here is the array:
Array
(
[0] => Array
(
[name] => test_route
[path] => /test
[controller] => TestController
[action] => indexAction
)
[1] => Array
(
[name] => hello_route
[path] => /hello
[controller] => HelloController
[action] => helloAction
)
)
and here is the method:
public function getRoute($path = "", $name = "")
{
foreach($this->routes as $key => $val)
{
if($val['path'] === $path || $val['name'] === $name)
{
return $this->routes[$key];
}
else
{
return false;
}
}
}
Just modifying on the code you provided , may be you should try something like this :
public function getRoute($path = "", $name = "")
{
foreach($this->routes as $key => $val)
{
if($val['path'] === $path || $val['name'] === $name)
{
return $this->routes[$key];
}
}
return false;
}
Your method exists after examining the first element. Remove the else block and put the return false outside the loop.
foreach($this->routes as $key => $val)
{
if($val['path'] === $path || $val['name'] === $name)
{
return $this->routes[$key];
}
}
return false;
I'm not sure why /test even works. You're dealing with a multidimensional array. foreach does not do deep searches. You're going to have to modify your code to this:
public function getRoute($path = "", $name = "")
{
foreach($this->routes as $route) {
foreach($route as $key => $val)
{
if($val['path'] === $path || $val['name'] === $name)
{
return $route[$key];
}
}
}
return false;
}

I'm trying to solve an issue where I have an multilevel array that needs to be filtered with user controlled filters.
Example of the array
[1] => Array
(
[objectID] => 5038
[Data] => Array
(
[originalId] => 6
)
[titles] => InfoType Object
(
[_] => string
[language] => eng
)
)
The filters would be then language and objectID, for example.
Anything that doesn't meet the criteria will have to be excluded. Sounds perfectly find if that would be a SQL query, but it's not. The API returns a string that cannot be controlled and it's in a form of an array. Have to work with what you have.
The idea came up to write a function that would prepare an if-statement. Problem is that you can't do just that
foreach ($cache as $listing) {
foreach ($filters as $filter_param => $filter_value) {
if ($query) $output[] = $listing;
}
}
In this case the $query would be equal to something like this:
$listing["titles"]["language"] =="eng" && $listing["objectID"] =="5038"
I'm pretty sure there's an easier way that wouldn't actually be bad. Really stuck with this one.
function isGood($what, $filters) {
foreach ($filters as $key => $value) {
if (is_array($value)) {
if (isGood($what[$key], $value) === false) {
return false;
}
} else {
if ($what[$key] != $value) {
return false;
}
}
}
return true;
}
foreach($cache as $listing) {
if (isGood($listing, $filters)) {
$output[] = $listing;
}
}
I created a recursive function to find a key-value in a multidimensional array
Function:
public function find_key_recursive($haystack, $needle) {
foreach($haystack as $key=>$value) {
if(is_array($value)){
$this->find_key_recursive($value, $needle);
} else if($key === $needle) {
return $value;
}
}
}
(Part of) Array:
$oLayoutProperties =
Array
(
[header] => Array
(
[logo_float] => left
[logo_upload] => http://placehold.it/150x100&text=afbeelding
[logo_margin_top] => 0
[searchbar_toggle] => false
[language_toggle] => false
[color] => 0
[font_size] => 12
[background_color] => 0
)
[menu] => Array
(
[menu_type] => full
[menu_align] => left
[menu_position_toggle] => false
[menuheight] => Array
(
[bar_height] => 0
)
[color] => 0
[font_size] => 12
[text_transform] => like_pagetitle
[background_color_hover] => 0
[color_hover] => 0
)
[submenu] => Array
(
[color] => 0
[font-size] => 12
[item_height] => 0
[item_width] => 0
[text-transform] => like_pagetitle
[background_color] => 0
[background_color_hover] => 0
[color_hover] => 0
)
)
I call the function as following:
$oElement_controller->find_key_recursive($oLayoutProperties, 'logo_float');
I validated (using echo's) that the key 'logo_float' indeed gets found, but I don't seem to be able to cancel the recursive function?
I tried the following:
return false;
break;
None of the above seem to work.
How do you stop a recursive function?
You can use a static variable to remember the status between multiple function calls. It makes the function remember the value of the given variable ($needle_value in this example) between multiple calls.
public function find_key_recursive($haystack, $needle){
static $needle_value = null;
if($needle_value != null){
return $needle_value;
}
foreach($haystack as $key=>$value) {
if(is_array($value)){
$this->find_key_recursive($value, $needle);
} else if($key === $needle) {
$needle_value = $value;
return $needle_value;
}
}
}
This function finally returns $needle_value, which is your desired needle in the haystack.
public function find_key_recursive($haystack, $needle) {
foreach($haystack as $key=>$value) {
if(is_array($value)){
var $found = $this->find_key_recursive($value, $needle);
if ($found){
return $found;
}
} else if($key === $needle) {
return $value;
}
}
return false;
}
I haven't touched PHP in a while, but something like this will probably work.
You can put the result in a variable passed by reference, like this:
public function find_key_recursive($haystack, $needle, &$found) {
foreach($haystack as $key => $value) {
if (is_array($value)) {
$this->find_key_recursive($value, $needle, $found);
} else if($key === $needle) {
$found = $value;
return;
}
}
}
$found = false;
$oElement_controller->find_key_recursive($oLayoutProperties, 'logo_float', $found);
if ($found !== false) {
// found!
}
I have following array
Array
(
[0] => Array
(
[data] => PHP
[attribs] => Array
(
)
[xml_base] =>
[xml_base_explicit] =>
[xml_lang] =>
)
[1] => Array
(
[data] => Wordpress
[attribs] => Array
(
)
[xml_base] =>
[xml_base_explicit] =>
[xml_lang] =>
)
)
one varialbe like $var = 'Php, Joomla';
I have tried following but not working
$key = in_multiarray('PHP', $array,"data");
function in_multiarray($elem, $array,$field)
{
$top = sizeof($array) - 1;
$bottom = 0;
while($bottom <= $top)
{
if($array[$bottom][$field] == $elem)
return true;
else
if(is_array($array[$bottom][$field]))
if(in_multiarray($elem, ($array[$bottom][$field])))
return true;
$bottom++;
}
return false;
}
so want to check if any value in $var is exists in array(case insensitive)
How can i do it without loop?
This should work for you:
(Put a few comments in the code the explain whats goning on)
<?php
//Array to search in
$array = array(
array(
"data" => "PHP",
"attribs" => array(),
"xml_base" => "",
"xml_base_explicit" => "",
"xml_lang" => ""
),
array(
"data" => "Wordpress",
"attribs" => array(),
"xml_base" => "",
"xml_base_explicit" => "",
"xml_lang" => "Joomla"
)
);
//Values to search
$var = "Php, Joomla";
//trim and strtolower all search values and put them in a array
$search = array_map(function($value) {
return trim(strtolower($value));
}, explode(",", $var));
//function to put all non array values into lowercase
function tolower($value) {
if(is_array($value))
return array_map("tolower", $value);
else
return strtolower($value);
}
//Search needle in haystack
function in_array_r($needle, $haystack, $strict = false) {
foreach ($haystack as $item) {
if (($strict ? $item === $needle : $item == $needle) || (is_array($item) && in_array_r($needle, $item, $strict))) {
return true;
}
}
return false;
}
//Search ever value in array
foreach($search as $value) {
if(in_array_r($value, array_map("tolower", array_values($array))))
echo $value . " found<br />";
}
?>
Output:
php found
joomla found
to my understanding , you are trying to pass the string ex : 'php' and the key : 'data' of the element .
so your key can hold a single value or an array .
$key = in_multiarray("php", $array,"data");
var_dump($key);
function in_multiarray($elem, $array,$field)
{
$top = sizeof($array) - 1;
$bottom = 0;
while($bottom <= $top)
{
if(is_array($array[$bottom][$field]))
{
foreach($array[$bottom][$field] as $value)
{
if(strtolower(trim($value)) == strtolower(trim($elem)))
{
return true;
}
}
}
else if(strtolower(trim($array[$bottom][$field])) == strtolower(trim($elem)))
{
return true;
}
$bottom++;
}
return false;
}
I've trawled the site and the net and have tried various recursive functions etc to no avail, so I'm hoping someone here can point out where I'm going wrong :)
I have an array named $meetingArray with the following values;
Array (
[0] => Array (
[Meet_ID] => 9313
[Meet_Name] => 456136
[Meet_CallInNumber] =>
[Meet_AttendeeCode] =>
[Meet_Password] =>
[Meet_ScheduledDateTime] => 2011-07-18 16:00:00
[Meet_ModeratorCode] =>
[Meet_RequireRegistration] => 0
[Meet_CurrentUsers] => 0
)
[1] => Array (
[Meet_ID] => 9314
[Meet_Name] => 456120
[Meet_CallInNumber] =>
[Meet_AttendeeCode] =>
[Meet_Password] =>
[Meet_ScheduledDateTime] => 2011-07-18 16:00:00
[Meet_ModeratorCode] =>
[Meet_RequireRegistration] => 0
[Meet_CurrentUsers] => 0
)
)
I also have a variable named $meetID.
I want to know if the value in $meetID appears in [Meet_Name] within the array and simply evaluate this true or false.
Any help very much appreciated before I shoot myself :)
function multi_in_array($needle, $haystack, $key) {
foreach ($haystack as $h) {
if (array_key_exists($key, $h) && $h[$key]==$needle) {
return true;
}
}
return false;
}
if (multi_in_array($meetID, $meetingArray, 'Meet_Name')) {
//...
}
I am unsure what you mean by
$meetID appears in [Meet_Name]
but simply substitute the $h[$key]==$needle condition with something that meets your needs.
For single-dimensional arrays you can use array_search(). This can be adapted for multi-dimensional arrays like so:
function array_search_recursive($needle, $haystack, $strict=false, $stack=array()) {
$results = array();
foreach($haystack as $key=>$value) {
if(($strict && $needle === $value) || (!$strict && $needle == $value)) {
$results[] = array_merge($stack, array($key));
}
if(is_array($value) && count($value) != 0) {
$results = array_merge($results, array_search_recursive($needle, $value, $strict, array_merge($stack, array($key))));
}
}
return($results);
}
Write a method something like this:
function valInArr($array, $field, $value) {
foreach ($array as $id => $nestedArray) {
if (strpos($value,$nestedArray[$field])) return $id;
//if ($nestedArray[$field] === $value) return $id; // use this line if you want the values to be identical
}
return false;
}
$meetID = 1234;
$x = valInArr($array, "Meet_Name", $meetID);
if ($x) print_r($array[$x]);
This function will evaluate true if the record is found in the array and also enable you to quickly access the specific nested array matching that ID.
I have the following multidimensional $array:
Array
(
[0] => Array
(
[domain] => example.tld
[type] => 2
)
[1] => Array
(
[domain] => other.tld
[type] => 2
)
[2] => Array
(
[domain] => blaah.tld
[type] => 2
)
)
I simply want to recursively search all the arrays on both key and value, and return true if the key/value was found or false if nothing was found.
Expected output:
search_multi_array($array, 'domain', 'other.tld'); // Will return true
search_multi_array($array, 'type', 'other.tld'); // Will return false
search_multi_array($array, 'domain', 'google.com'); // Will return false
I've figured out a ugly-ugly method to search against the domain against all keys with this function:
function search_multi_array($search_value, $the_array) {
if (is_array($the_array)) {
foreach ($the_array as $key => $value) {
$result = search_multi_array($search_value, $value);
if (is_array($result)) {
return true;
} elseif ($result == true) {
$return[] = $key;
return $return;
}
}
return false;
} else {
if ($search_value == $the_array) {
return true;
}
else
return false;
}
}
Can anyone do better and match both against the key and value in a more elegant way?
If it doesn't go beyond those 2 levels, flipping keys/merging makes life a lot more pleasant:
<?php
$data = array
(
'0' => array
(
'domain' => 'example.tld',
'type' => 2
),
'1' => array
(
'domain' => 'other.tld',
'type' => 2,
),
'2' => array
(
'domain' => 'blaah.tld',
'type' => 2
)
);
$altered = call_user_func_array('array_merge_recursive',$data);
var_dump($altered);
var_dump(in_array('other.tld',$altered['domain']));
var_dump(in_array('other.tld',$altered['type']));
var_dump(in_array('google.com',$altered['domain']));
To go beyond 2nd level, we have to loop once through all the nodes:
$option2 = array();
foreach(new RecursiveIteratorIterator(new RecursiveArrayIterator($data)) as $key => $value){
$option2[$key][] = $value;
}
var_dump($option2);
One way is to create a reverse mapping from [domain] => [indices] and from [type] => [indices]. It's probably not going to save you much unless you do lots of searches.
(hint: you probably want to wrap it into a class to prevent inconsistencies in the mappings)
also, anytime you see something like this:
if ($search_value == $the_array) {
return true;
} else {
return false;
}
you can always turn it into:
return $search_value == $the_array;
function search_mutli_array($SearchKey, $SearchValue, $Haystack)
{
$Result = false;
if (is_array($Haystack))
{
foreach ($Haystack as $Key => $Value)
{
if (is_array($Value))
{
if (search_mutli_array($SearchKey, $SearchValue, $Value))
{
$Result = true;
break;
}
}
else if ($SearchKey == $Key && $SearchValue == $Value)
{
$Result = true;
break;
}
}
}
return $Result;
}
