list and count elements in array php - php

Question

I have the following array and am trying to loop through it with php, generate a list of the "Type" and count how many. The Type is the key, but there will be unique values such as Call, To-do, Meeting, Proposal, etc. My goal is to have the following out put:
Call 2
To-do 1
Meeting 3
Proposal 4
The above are not the values that will be output from the following array, but I wanted you to have an idea of what I am trying to accomplish. Please help!
Array (
[0] => Array (
[0] => Call
[Type] => Call
[1] => fxxxx#xxxxentllc.com
[EmailAddress] => xxxxr#xxxxentllc.com

Answer 1

This should do it:
$type_counts = array_count_values(array_map(function($x) {return $x['Type'];}, $array));
The array_map will return an array containing all the Type elements, then array_count_values will count the number of each of these and return this as an associative array.

Answer 2

something along the lines of:
foreach ($array as $key => $value) {
if (isset($result[$key])) {
$result[$key]++;
} else {
$result[$key] = 1;
}
}
if it is a muldi-dimensional array, just put another for each in there but that should give you an idea

Answer 3

$types = array();
foreach($array as $item) {
isset(${$item['Type']}) ? ${$item['Type']}++ : ${$item['Type']} = 1;
if(!in_array($item['Type'], $types) {
$types[] = $item['Type'];
}
foreach($types as $type) {
echo "$type ${$type}\n";
}

Answer 4

I think you can loop in your array and count each occorrence
$Call = 0;
$To_do = 0;
$Meeting = 0;
$Proposal = 0;
foreach($array as $data)
{
if($data['Type'] == 'Call')
{
$Call++;
} else if($data['Type'] == 'To-do')
{
$To_do++;
} else if($data['Type'] == 'Meeting')
{
$Meeting++;
} else if($data['Type'] == 'Proposal')
{
$Proposal++;
}
}
In this way you will have stored in each variable $Call $To_do $Meeting $Proposal its relative count

Answer 5

you can use (array_count_values($array));
http://php.net/manual/en/function.array-count-values.php
This gives count of all the keys in an array.
If you want only for the specific keys then use foreach loop
The one Petros mentioned is the best way to do it.

Answer 6

I would do something along the lines of:
$your_array = /* Your Array */
$types_count = array();
foreach ($your_array as $type_array){
$types_count[$type_array['Type']]++;
}
