PHP array length or size count

count( $array, $mode)

$array = array  ("ABC","DEF", "GHI","KLM");

print count($array);

$value= array(2,5,6,8,9);

echo "size of array = ".sizeof($value)."<br>"; // Output = 5

With COUNT_RECURSIVE (or 1)

<?Php
$a=array(array("product"=>"apple","quantity"=>2),
array("product"=>"Orange","quantity"=>4),
array("product"=>"Banana","quantity"=>5),
array("product"=>"Mango","quantity"=>7),
);
echo count($a); // Output = 4
echo "<br>";
echo count($a,1); // Output = 12
?>

4
12

echo sizeof($a); // Output = 4
echo "<br>";
echo sizeof($a,1); // Ouput = 12

Words Count ( Sample projects using sizeof function)

1. Store the paragraph of text in a string variable 

2. Break the variable and create an array by using explode() function with space as delimiter 

3. Count the number of elements present in the array.

<?Php
///Storing the sample paragraph in a variable /////
$string='This is a sample string used to count the number of words present in a paragraph of data. You can read this sample text by asking user to enter them in a textara or you can directly read the data present in a file by using PHP file commands.';

///Creating the array by using split function ////

$our_array=explode(" ",$string);

///Generating the output ////
echo "Total Number of words = ".sizeof($our_array);
?>
