Add all values in array php

How can I add all of my array values together in PHP?

There are three ways around this class of bug: Avoid write-back and just use the full array expression to write values inside the loop; Don’t re-use the variable in the same scope, even for another loop; Use on the variable to disconnect it from the array it will write back to. You can iterate over an array using a loop (like ), and then add all the values up to a variable.

How can I add all of my array values together in PHP? Is there a function for this?

If your array consists of numbers, you can use array_sum to calculate a total. Example from the manual:

$a = array(2, 4, 6, 8); echo "sum(a) = " . array_sum($a) . "\n"; 

If your array consists of strings, you can use implode :

it would turn an array like this:

strawberries peaches pears apples 

strawberries,peaches,pears,apples 

if your array are all numbers and you want to add them up, use array_sum(). If not, you can use implode()

array_sum function should help. Here I presume your array comprises of integer or float values.

Let the given array values may contain integer or may not be. It would be better to have check and filter the values.

$array = array(-5, " ", 2, NULL, 13, "", 7, "\n", 4, "\t", -2, "\t", -8); // removes all NULL, FALSE and Empty Strings but leaves 0 (zero) values $result = array_filter( $array, 'is_numeric' ); echo array_sum($result); 

How to add elements to an array in a loop using php, To add an element, use empty brackets. foreach ($states as $state) < foreach ($cities as $city) < $data [$state] [] = $city; >> This will create an array like this array ( ‘nc’ => array (‘city1’, ‘city2’, ), ‘sc’ => array (‘city1’, ‘city2’, ) ) See manual under «Creating/modifying with square bracket syntax» Share Improve this answer

How can I add all the values in an array? [duplicate]

I have an array (or is it an object?) that looks like this:

Array ( [0] => 5 [1] => 4 [2] => 3 [3] => 4 [4] => 4 [5] => 4 [6] => 4 [7] => 3 [8] => 4 [9] => 5 [10] => 3 [11] => 4 [12] => 4 [13] => 4 [14] => 3 [15] => 4 [16] => 4 [17] => 5 ) 

How do I add up all the values inside it. ie. 5 + 4 + 3 etc. Any ideas?

What you have is an array, not an object.

You can iterate over an array using a loop (like foreach ), and then add all the values up to a variable.

$total = 0; foreach($array as $val) $total += $val; 

OR use a core function array_sum() .

Careful with the second one, because if there is a float value in your array, and you expect an integer value returned, this function will return a float .

The PHP object you are referring to is called an Array. An array is an arrangement of objects usually in rows and columns.

To perform the operation of addition on all elements in the array, the following snippet may be used:

This code snippet iterates through the array using the foreach construct. Each iteration takes a value of the array at the current pointer location and stores it in $value.

Use for or foreach to iterate through the array and keep adding each element to a variable outside the scope of the loop. You can also take the easy route and use a built-in function.

$total = 0; foreach($arr as $e) $total += $e; 

How to add array values to another array in PHP?, I tried with array_push but add the entire array in the [0] position or in the [2] position in the second array. Anyone has any ideas? php arrays multidimensional-array for-loop foreach

PHP Arrays: How to add ‘key & value’ to an existing array

I do not know how to add a key and value to the existing array. My array goes like this. Initially I have tried adding using array_push() but it added not as I needed it.

I have given my output after I gave the ‘var_dump’.

array (size=6) 0 => array (size=3) 'id' => int 7 'title' => string 'Pongal' (length=6) 'start' => string '2016-05-16' (length=10) 1 => array (size=3) 'id' => int 8 'title' => string 'big day' (length=7) 'start' => string '2016-05-04' (length=10) 2 => array (size=3) 'id' => int 9 'title' => string 'marriage day' (length=12) 'start' => string '2016-05-19' (length=10) 3 => array (size=3) 'id' => int 10 'title' => string 'Karthiks bday' (length=14) 'start' => string '2016-06-11' (length=10) 4 => array (size=3) 'id' => int 12 'title' => string 'Election date announced' (length=23) 'start' => string '2016-06-01' (length=10) 

Now, I’d like to insert array(‘sample_key’ => ‘sample_value’) after all the elements of each array.

How can I do it? This is I want the result to be like this:-

array (size=6) 0 => array (size=3) 'id' => int 7 'title' => string 'Pongal' (length=6) 'start' => string '2016-05-16' (length=10) ‘color’ => ‘red’ 1 => array (size=3) 'id' => int 8 'title' => string 'big day' (length=7) 'start' => string '2016-05-04' (length=10) ‘color’ => ‘red’ 2 => array (size=3) 'id' => int 9 'title' => string 'marriage day' (length=12) 'start' => string '2016-05-19' (length=10) ‘color’ => ‘red’ 3 => array (size=3) 'id' => int 10 'title' => string 'Karthiks bday' (length=14) 'start' => string '2016-06-11' (length=10) ‘color’ => ‘red’ 4 => array (size=3) 'id' => int 12 'title' => string 'Election date announced' (length=23) 'start' => string '2016-06-01' (length=10) ‘color’ => ‘red’ 

Note that I have added ‘color’ => ‘red’ to all the indexes

Just do this: Working demo

using the & you can change the main array, and just use $val[‘color’] = ‘red’ to add a new key , value pair in the array.

Note that the ‘write-back’ feature of the ampersand persists even after the loop has finished: resetting $val to a new value will change the last element in $val , which is often unexpected. There are three ways around this class of bug:

• Avoid write-back and just use the full array expression to write values inside the loop;
• Don’t re-use the $val variable in the same scope, even for another foreach() loop;
• Use unset() on the $val variable to disconnect it from the array it will write back to.

Add two arrays in PHP

I have two arrays and I want to add it to make a combined one.

$first = Array ( [0] => Array ( [countrySelected] => 3 [stateSelected] => 176 [citySelected] => 551 ) ) $second = Array ( [0] => Array ( [countrySelected] => 3 [stateSelected] => N/A [citySelected] => N/A ) ) 

Now I want to make them a combined one:

Array ( [0] => Array ( [countrySelected] => 3 [stateSelected] => 176 [citySelected] => 551 ) [1] => Array ( [countrySelected] => 3 [stateSelected] => N/A [citySelected] => N/A ) ) 

I tried it with array_merge but it combines them in one but I need two elements like [0], [1] as above.

$arr1 = array( array( "countrySelected" => 3, "stateSelected" => 176, "citySelected" => 551 ) ); $arr2 = array( array( "countrySelected" => 3, "stateSelected" => Null, "citySelected" => Null ) ); $arr3 = array_merge_recursive($arr1, $arr2); print_r($arr3); Result: Array ( [0] => Array ( [countrySelected] => 3 [stateSelected] => 176 [citySelected] => 551 ) [1] => Array ( [countrySelected] => 3 [stateSelected] => [citySelected] => ) ) 

have you used array_push ? it could be something like:

first parameter is the destination, the second is the element to insert.

array_push() insert it on the last field in array.

Here you are, simply use array_map like below:

 3, "stateSelected" => 176, "citySelected" => 551 ) ); $array2 = array( array( "countrySelected" => 3, "stateSelected" => "N/A", "citySelected" => "N/A", ) ); array_map(function($arr) use(&$array1)< $array1[] = $arr; >, $array2); print_r($array1); 

check output here https://paiza.io/projects/lJSL9E0IKJ1VF5IreDNmvA

$arrayone = array(WHATEVER VALUES ARE IN THIS ARRAY); $arraytwo = array(WHATEVER VALUES ARE IN THIS ARRAY)); 

then combine the arrays like following

$arraythree = array($arrayone, $arraytwo); var_dump($arraythree);

Internally PHP uses copy-on-write in as many situations as possible for reasons of performance and memory efficiency. …
