How to display certain text from memory (php)?

Question

PHP

Please tell me how to write php.
Code: <?php echo $category['href']; ?>
Outputs: /index.php?route=product/category&path=60
How to write php to display: just the number 60?

Answer 1

<?php echo str_replace('.png', '', $category['href']); ?>

Answer 2

It's easier that way. This is the easiest way.
<?php echo '60'; ?>

Answer 3

How can you even waste your time asking such questions?
From memory! It's "from the value of the variable/array", not from memory!

$testString = '/index.php?route=product/category&path=60';
parse_str(parse_url($testString, PHP_URL_QUERY), $params);
print_r($params);

Conclusion:

Array
(
    [route] => product/category
    [path] => 60
)

Answer 4

preg_match("/\d+/", $category['href'], $match);
echo $match[0];
