get string piece, before last needle

Question

Given

 $str = "asd/fgh/jkl/123

If we want to get string piece after last slash , we can use function strrchr() right? In php not function, to get string piece, before last slah, that is asd/fgh/jkl ?

I know this can make via regex or other way, I am asking about internal function?

Answer 1

You can do this by:

explode — Split a string by string (Documentation)

$pieces = explode("/", $str );

example

$str = "asd/fgh/jkl/123";
$pieces = explode("/", $str );
print_r($pieces);

$count= count($pieces);
echo $pieces[$count-1]; //or
echo  end($pieces);

Answer 2

You can use

$str = "asd/fgh/jkl/123";
echo substr($str, 0,strrpos($str, '/'));

Output

asd/fgh/jkl

Answer 3

$str = "asd/fgh/jkl/123";

$lastPiece = end(explode("/", $str));

echo $lastPiece;

output: 123;

explode() converts the string into an array using "/" as a separator (you can pick the separator)

end() returns the last item of the array
