I have got an array that contains different kinds of element.
The array can have different dimension in different fields.
I want to write a function to check if there are some variables in the array are empty.
The sample array is like the following.
$array = new array(
'a'=>'A',
'b' => new array('B',''),
'c'=> ''
);
Here is a function that will go through all the arrays:
$isEmpty = checkArray( $arr );
if ( $isEmpty ) {
echo "there are empties!";
} else {
echo "no empties!";
}
function checkArray( $array ) {
foreach ( $array as $key => $value ) {
if ( is_array( $value ) ) {
if ( checkArray( $value ) ) return true;
} else {
if ( empty( $value ) ) return true;
}
}
return false;
}
How about this:
foreach ($array as $key => $value) {
if (empty($value)) {
do_stuff();
}
}

The problem is that you are setting the content type header to text/plain
header ( "content-type: text/plain;charset=utf8" );
What you need to do is set it to text/html
header ( "content-type: text/html; charset=utf8" );
I would, however, suggest you re-evaluate how you notify the user of a successful login if you wish to dump HTML after, as this
login success!<!DOCTYPE html PUB...
is not good at all.
Try and keep everything you want to render inside the tags, and keep those tags inside your tags.
Good luck!
I have an array that looks like this:
$array = array (
[level_1] => array (
[level_2] => array (
[level_3] => something
)
),
[level_12] => array (
[level_2] => somethingelse
),
[level_13] => array (
[level_22] => array (
[level_3] => something
)
),
);
The keys or values aren't always unique but the branches are.
And I have a string that looks like this:
$string = 'level_1-level_2-level_3';
Those are the keys for a branch.
And I need to somehow get the value from the array based on that string?
Like this:
$string_array = explode('-', $string);
$array[$string_array[0]][$string_array[1]][$string_array[2]] // something
But since the depth can be different this is not a viable solution...
Try this simple example, no need for a recursive function:
function get_item( $path, $array )
{
$paths = explode( '-', $path );
$result = $array;
foreach ( $paths as $path) {
isset( $result[$path] ) ? $result = $result[$path] : $result = false;
}
return $result;
}
$path = 'level_1-level_2-level_3';
echo get_item( $path, $array );
Try this:
$array = array (
'level_1' => array (
'level_2' => array (
'level_3' => 'something'
)
),
'level_12' => array (
'level_2' => 'somethingelse'
),
'level_13' => array (
'level_22' => array (
'level_3' => 'something'
)
),
);
$string = 'level_1-level_2-level_3';
$keys = explode('-', $string);
echo getItemIterative($keys, $array);
echo "\n";
echo getItemRecursive($keys, $array);
function getItemIterative($keys, $array)
{
$value = null;
foreach ($keys as $key) {
if ($value == null) {
$value = $array[$key];
}
if (is_array($value) && array_key_exists($key, $value)) {
$value = $value[$key];
}
}
return $value;
}
function getItemRecursive($keys, $array)
{
$key = array_shift($keys);
$value = $array[$key];
if (empty($keys)) {
return $value;
} else {
return getItemRecursive($keys, $value);
}
}
Make a $result variable which initially points to the root of the array, and loop through the levels of your $string_array 'til $result points at the leaf you were looking for.
// stuff you already have:
$array = array(...); // your big array
$string = 'level_1-level_2-level_3';
$string_array = explode('-', $string);
// new stuff:
$result = $array;
foreach ($string_array as $level) {
$result = $result[$level];
}
echo $result; // 'something'

i'm gona crazy, debuting in php..
I need to check if key value of an multidimentionnal array are all numeric..
a print_r() of my $values_arr give that:
Array ( [coco] => Array ( [0] => 18 [1] => 99 ) [chanel] => 150
I need to check if 18 and 99 and 150 are numeric, i will don't know what will in the array , and this array will not more 2 dimention.
I tryed many things, the last one..:
foreach ( $values_arr as $foo=>$bar ) {
if( !in_array( $foo, $_fields_arr ) || !is_numeric($bar ) ) {
echo "NOTGOOD";
}
}
****UPDATE****
new test :Here because chanel isnot int , this exemple should be echo "not goud",
but its not the case..
$_fields_arr = array('coco','chanel','other');
$ary = array(
'coco' => array(18, 99),
'chanel' => 'yu'
);
function allIntValues($o)
{
if (is_int($o)) return true;
if (is_array($o)){
foreach ($o as $k => $v) {
if (!is_int($v)) return false;
}
}
return true;
}
foreach ($ary as $k => $v) {
if (!in_array($k, $_fields_arr) || !#allIntValues($v)){
echo "notgood";
}
else echo "good";
}
thanks for any help,
regards
Update:
$ary = Array(
'coco' => array(18, 99),
'chanel' => 150
);
$_fields_arr = array('coco', 'chanel');
function allIntValues($o)
{
if (is_int($o)) return true;
if (is_array($o)){
foreach ($o as $k => $v) {
if (!is_int($v)) return false;
}
}
return true;
}
foreach ($ary as $k => $v) {
if (in_array($k, $_fields_arr) && #allIntValues($v)){
// $ary[$k] is no good
}
}
Assuming you want to test if all values are numeric (despite how deep the value's nested):
function is_numeric_array($ary)
{
foreach ($ary as $k => $v)
{
if (is_array($v))
{
if (!is_numeric_array($v))
return false;
}
else if (!is_numeric($v))
return false;
}
return true;
}
That will (recursively) check the array and make sure every value is numeric within the array.
array(1,2,3) // true
array('foo','bar','baz') // false ('foo', 'bar' & 'baz')
array(1,2,array(3,4)) // true
array(array(1,'foo'),2,3) // false (foo)
array("1,", "2.0", "+0123.45e6") // true
You are using the value instead of the key:
if( !in_array( $bar, $_fields_arr ) || !is_numeric($foo ) ) {
I have a multidimensional array e.g. (this can be many levels deep):
$array = Array (
[21] => Array ( )
[24] => Array (
[22] => Array ( )
[25] => Array (
[26] => Array ( )
)
)
)
I am trying to loop through it to see if a certain key exists:
$keySearch = 22; // key searching for
function findKey($array, $keySearch) {
foreach ($array as $item){
if (isset($item[$keySearch]) && false === findKey($item[$keySearch], $item)){
echo 'yes, it exists';
}
}
}
findKey($array, $keySearch);
But it finds nothing. Is there an error in the loop?
array_key_exists() is helpful.
Then something like this:
function multiKeyExists(array $arr, $key) {
// is in base array?
if (array_key_exists($key, $arr)) {
return true;
}
// check arrays contained in this array
foreach ($arr as $element) {
if (is_array($element)) {
if (multiKeyExists($element, $key)) {
return true;
}
}
}
return false;
}
Working example: http://codepad.org/GU0qG5su
I played with your code to get it working :
function findKey($array, $keySearch)
{
foreach ($array as $key => $item) {
if ($key == $keySearch) {
echo 'yes, it exists';
return true;
} elseif (is_array($item) && findKey($item, $keySearch)) {
return true;
}
}
return false;
}
Here is a one line solution:
echo strpos(json_encode($array), $key) > 0 ? "found" : "not found";
This converts the array to a string containing the JSON equivalent, then it uses that string as the haystack argument of the strpos() function and it uses $key as the needle argument ($key is the value to find in the JSON string).
It can be helpful to do this to see the converted string: echo json_encode($array);
Be sure to enclose the needle argument in single quotes then double quotes because the name portion of the name/value pair in the JSON string will appear with double quotes around it. For instance, if looking for 22 in the array below then $key = '"22"' will give the correct result of not found in this array:
$array =
Array (
21 => Array ( ),
24 =>
Array (
522 => Array ( ),
25 =>
Array (
26 => Array ( )
)
)
);
However, if the single quotes are left off, as in $key = "22" then an incorrect result of found will result for the array above.
EDIT: A further improvement would be to search for $key = '"22":'; just incase a value of "22" exists in the array. ie. 27 => "22" In addition, this approach is not bullet proof. An incorrect found could result if any of the array's values contain the string '"22":'
function findKey($array, $keySearch)
{
// check if it's even an array
if (!is_array($array)) return false;
// key exists
if (array_key_exists($keySearch, $array)) return true;
// key isn't in this array, go deeper
foreach($array as $key => $val)
{
// return true if it's found
if (findKey($val, $keySearch)) return true;
}
return false;
}
// test
$array = Array (
21 => Array ( 24 => 'ok' ),
24 => Array (
22 => Array ( 29 => 'ok' ),
25 => Array (
26 => Array ( 32 => 'ok' )
)
)
);
$findKeys = Array(21, 22, 23, 24, 25, 26, 27, 28, 29, 30);
foreach ($findKeys as $key)
{
echo (findKey($array, $key)) ? 'found ' : 'not found ';
echo $key.'<br>';
}
returns false if doesn't exists, returns the first instance if does;
function searchArray( array $array, $search )
{
while( $array ) {
if( isset( $array[ $search ] ) ) return $array[ $search ];
$segment = array_shift( $array );
if( is_array( $segment ) ) {
if( $return = searchArray( $segment, $search ) ) return $return;
}
}
}
return false;
}
For sure some errors, is this roughly what you are after? (Untested code):
$keySearch=22; // key seraching for
function findKey($array, $keySearch)
{
// check whether input is an array
if(is_array($array)
{
foreach ($array as $item)
{
if (isset($item[$keySearch]) || findKey($item, $keysearch) === true)
{
echo 'yes, it exists';
return true;
}
}
}
}
Here is one solution that finds and return the value of the key in any dimension array..
function findValByKey($arr , $keySearch){
$out = null;
if (is_array($arr)){
if (array_key_exists($keySearch, $arr)){
$out = $arr[$keySearch];
}else{
foreach ($arr as $key => $value){
if ($out = self::findValByKey($value, $keySearch)){
break;
}
}
}
}
return $out;
}
I did modified to return value of searched key:
function findKeyInArray($array, $keySearch, &$value)
{
foreach ($array as $key => $item) {
if ($key === $keySearch) {
$value = $item;
break;
} elseif (is_array($item)) {
findKeyInArray($item, $keySearch,$value);
}
}
}
$timeZone = null;
findKeyInArray($request, 'timezone', $timeZone);
I seem to be a little lost on what to so about this, im trying to parse out some info but the stdClass is going to always be changing, so im not too sure on what to do about it and could use come guidance.
//Query
$query = new EntityFieldQuery;
$result = $query
->entityCondition('entity_type', 'taxonomy_term')
->propertyCondition('name', 'GOOG')
->propertyCondition('vid', '3')
->execute();
//This is the output
Array
(
[taxonomy_term] => Array
(
[1868] => stdClass Object
(
[tid] => 1868
)
)
)
Now I can get to the tid by using
$result['taxonomy_term']['1868']->tid
but as mentioned before the the stdClass will be always changing.
You can use recurssive array search like this:
function array_searchRecursive( $needle, $haystack, $strict=false, $path=array() )
{
if( !is_array($haystack) ) {
return false;
}
foreach( $haystack as $key => $val ) {
if( is_array($val) && $subPath = array_searchRecursive($needle, $val, $strict, $path) ) {
$path = array_merge($path, array($key), $subPath);
return $path;
} elseif( (!$strict && $val == $needle) || ($strict && $val === $needle) ) {
$path[] = $key;
return $path;
}
}
return false;
}
Usage:
$arr = (array) $yourObject;
$keypath = array_searchRecursive('tid', $arr);
Example:
$class = new stdClass;
$class->foo = 'foo';
$class->bar = 'bar';
$arr = (array) $class;
$keypath = array_searchRecursive('foo', $arr);
print_r($keypath);
Results:
Array
(
[0] => foo
)
So now to get actual value:
echo $keypath[0]; // foo
