I have a a multi-dimensional array, whose name is: $MyArray = array();.
This array can be used for showing the relation between things.
Array
(
[parent] => Array
(
[0] => Array
(
[1] => tom
[2] => bob
)
[1] => Array
(
[1] => liza
[2] => bob
)
[2] => Array
(
[1] => bob
[2] => john
)
[3] => Array
(
[1] => pet
[2] => john
)
)
[gender] => Array
(
[0] => Array
(
[1] => tom
[2] => male
)
[1] => Array
(
[1] => liza
[2] => female
)
[2] => Array
(
[1] => bob
[2] => male
)
[3] => Array
(
[1] => pet
[2] => female
)
)
)
Now, I want to return an array, which must be satisfied with all conditions:
Finds in the gender array, what line has the male value. This value is called: TempArray.
In what line of the TempArray; and, continue to finds what name in Sol_1 into the parent array.
Then returns into a multi-dimensional array: ResArray, like:
Array
(
[father] => Array
(
[0] => Array
(
[1] => tom
[2] => bob
)
[1] => Array
(
[1] => bob
[2] => john
)
)
[mother] => Array
(
[0] => Array
(
[1] => liza
[2] => bob
)
[1] => Array
(
[1] => pet
[2] => john
)
)
)
How to do it, with PHP?

I need help to get only the paired values of this arrays:
Array $requestedFields:
Array
(
[0] => id
[1] => first-name
[2] => last-name
[3] => username
[4] => email
[5] => truntt
[6] => fiff
)
Array $apiFields:
Array
(
[0] => Array
(
[0] => id
[1] => id
[2] => accounts.profile.basic
)
[1] => Array
(
[0] => first-name
[1] => fname
[2] => accounts.profile.basic
)
[2] => Array
(
[0] => last-name
[1] => lname
[2] => accounts.profile.basic
)
[3] => Array
(
[0] => username
[1] => username
[2] => accounts.profile.basic
)
[4] => Array
(
[0] => email
[1] => email
[2] => accounts.profile.emailaddress
)
[5] => Array
(
[0] => test-test
[1] => test
[2] => accounts.profile.test
)
)
I need to get the $apiFields elements matched with $requestedFields in this case only 0-4 elements values.
Any help is appreciated.
Use the below code:
foreach($apiFields as $key=>$arr){
if(!in_array($arr[0], $requestedFields)){
unset($apiFields[$key]);
}
}
It will give you the expected result in $apiFields array.
I have 2 PHP arrays that look like this..
$array1
--------
Array
(
[0] => Array
(
[0] => 64
[1] => Apple
)
[1] => Array
(
[0] => 22
[1] => Pear
)
[2] => Array
(
[0] => 3
[1] => Raisin
)
[3] => Array
(
[0] => 15
[1] => Grape
)
[4] => Array
(
[0] => 11
[1] => Banana
)
[5] => Array
(
[0] => 4
[1] => Orange
)
)
$array2
--------
Array
(
[0] => Array
(
[0] => 22
[1] => Pear
)
[1] => Array
(
[0] => 11
[1] => Banana
)
)
I want to merge the arrays together but put the matching items from $array2 at the top so the result would look like this...
$array3
-------
Array
(
[0] => Array
(
[0] => 22
[1] => Pear
)
[1] => Array
(
[0] => 11
[1] => Banana
)
[2] => Array
(
[0] => 64
[1] => Apple
)
[3] => Array
(
[0] => 3
[1] => Raisin
)
[4] => Array
(
[0] => 15
[1] => Grape
)
[5] => Array
(
[0] => 4
[1] => Orange
)
)
I'm not sure how to approach, should I merge the two first and then try and do some ordering, or is there a more efficient approach?
Get the 2nd array and then a rest of the 1st array
array_merge($arr2, array_udiff($arr1, $arr2, function($i1, $i2) {return $i1[0]-$i2[0];}));
I am working on my PHP project where I need to list all genres in database but uniquely. please help me.
$q_cat = "SELECT DISTINCT `genres` FROM `movie_meta`";
$ex = mysqli_query($con, $q_cat);
$array = array();
while ($res=mysqli_fetch_assoc($ex)) {
foreach($res as $value) {
$x = rtrim($value,',');
$array = explode(',', $x);
}
print_r($array);
}

I mean All Distinct Values from all array into one array.
Use array_merge() function. it will merge two or more array in one
http://php.net/manual/en/function.array-merge.php
You need to make a single array for all the unique data, store data in the array and make the value as key for getting the unique value. finally use the array_values function to get the values as result.
$array = array();
while ($res=mysqli_fetch_assoc($ex)) {
foreach($res as $value) {
$x = rtrim($value,',');
foreach(explode(',', $x) as $val){
$array[$val] = $val;
}
}
}
print_r(array_values($array));
Make associative array so while making associative array duplicate values will be removed
foreach($array as $value){
$temp[$value]=$value;
}
then remove key by using php function array_values
$unique_array= array_values($temp);
print_r($unique_array);
You will get this as Output
Array
(
[0] => Action
[1] => Crime
[2] => Thriller
[3] => Adventure
[4] => Comedy
[5] => Drama
)
I'm trying to combine a single-dimensional array with a multi-dimensional array. I see that there is an array_combine function and an array_merge function, but they don't seem to give me the result I need. I have the following arrays:
$days = Array (
[0] => Array (
[0] => 3
[1] => 6
)
[1] => Array (
[0] => 6
[1] => 12
)
[2] => Array (
[0] => 2
[1] => 4
)
)
$names = Array (
[0] => Joe Smith
[1] => John Doe
[2] => Jack Frost
)
and this is the result I get when using array_merge($days,$names):
$result = Array (
[0] => Array (
[0] => 3
[1] => 6
)
[1] => Array (
[0] => 6
[1] => 12
)
[2] => Array (
[0] => 2
[1] => 4
)
[3] => Joe Smith
[4] => John Doe
[5] => Jack Frost
)
How do I get the following result:
$result = Array (
[0] => Array (
[0] => John Smith
[1] => Array (
[0] => 3
[1] => 6
)
)
[1] => Array (
[0] => John Doe
[1] => Array (
[0] => 6
[1] => 12
)
)
[2] => Array (
[0] => Jack Frost
[1] => Array (
[0] => 2
[1] => 4
)
)
)
Any ideas? Thanks
Using example #4 from the docs for array_map(), here's a cool way to do it:
$result = array_map(null, $names, $days);
Suppose I had a excel xlsx document called names with a couple of entries and wanted to print out the names from a php file.
include 'simplexlsx.class.php';
$xlsx = new SimpleXLSX('names.xlsx');
print_r( $xlsx->rows() );
This would print:
Array ( [0] => Array ( [0] => John [1] => Smith ) [1] => Array ( [0]
=> Steven [1] => Brake ) [2] => Array ( [0] => Carter [1] => Firen ) [3] => Array ( [0] => Juan [1] => Lahyno ) [4] => Array ( [0] => Sarah
[1] => Parker ) [5] => Array ( [0] => Julie [1] => Roberts ) [6] =>
Array ( [0] => Will [1] => Smith ) [7] => Array ( [0] => Angelina [1]
=> Jolie ) )
Is there a way to print out the data in a readable way? Or does print_r not allow formatting of an array passed to it?
If you add
echo '<pre>';
print_r( $xlsx->rows() );
Then you see somethiink like this:
Array (
[0] => Array
(
[0] => John [1] => Smith
)
[1] => Array
(
[0] => Steven [1] => Brake
)
...
I hope this will help you
