[RESOLVED] counting array elements

j-dearden

Hey just another quick question reagrding arrays.

is there a way to count the number of elements in my array.

so for example

my array is as so

$array = array("1", "1", "2", "3", "4", "1");

i need it to output

1 = 3
2 = 1
3 = 1
4 = 1

well along those lines any way similar to the count function in mysql.

cheers 😃

mjax

print_r(array_count_values($array));

cheers for that works a treat, one other thing is there a way of displaying the results in a more user friendly manor or do u have to use print_r?

cheers again

Something more user-friendly?

Hmm...

Maybe this will work for you:

<?php
$num_array = array(1, 1, 2, 3, 4, 1, 2, 3, 3, 3, 4, 5, 18, 5);

$num_count = array();

foreach($num_array as $value) {

if(!isset($num_count[$value]))
{
	$num_count[$value] = 1;
}
else
{
	$num_count[$value] = $num_count[$value] + 1;
}
}

foreach($num_count as $key=>$value)
{
	echo $key . ' = ' . $value . '<br />';
}
?>

You will have to forgive me if this is a silly way to do this: I am just waking up, LOL!!! 😃

array_count_values() returns array - print_r() is the simplest method to view what are its values. Nevertheless you can use for, foreach, while loop... to display the result.

Ahhh! I TOLD you I was just waking up!! LOL.... :p

<?php
$num_array = array(1, 1, 2, 3, 4, 1, 2, 3, 3, 3, 4, 5, 18, 5);

$result = array_count_values($num_array);

foreach($result as $key=>$value)
{
	echo $key . ' = ' . $value . '<br />';
}
?>
