Created page with "<pre> Count( <array/binary-array> ) </pre> === Description === Returns the total amount of elements in an array. === Parameters === ==== array/binary-array ==== The array to..."

New page

<pre>
Count( <array/binary-array> )
</pre>

=== Description ===

Returns the total amount of elements in an array.

=== Parameters ===

==== array/binary-array ====

The array to use.

OR

The binary variable to use.

=== Return Value ===

Success - Returns the total amount of elements in the array/binary-array.

Failure - Returns -1.

=== Remarks ===

Remember that the value returned by Count is one greater than the index of an array's last element!

In Sputnik an array does not necessary start at index 0 and move upwards infact an array can start at any number and jump all over place this all depends where the user has placed items into the array.

If the user uses push() then all items in array will be correct order.

This also returns how many characters are in a string.

=== Example ===

<syntaxhighlight lang="sputnik">
$arrayOLD = array ( 10..15, 24..30 );

$i = 0;
Foreach( $arrayOLD as $j )
{
println("Element ($i) is: " . $j);
$i++;
}

println("Size is: " . Count($arrayOLD) ); // Prints 13
</syntaxhighlight>

Heres an example of getting the size of binary data :

<syntaxhighlight lang="sputnik">
$binary = Pack("z0", "Hello World!");
// Yes you can get the size of the binary byte array by using Count just like with arrays
println("The binary size is: " . Count($binary) );
Foreach ( $binary as $i )
{
println( "Byte: " . $i . " | Hex: " . Hex($i) . " | Char: " . Chr($i) );
}
</syntaxhighlight>
