How does PHP handle recursion compared to other programming languages like Java, and what specific issues can arise when implementing recursive functions in PHP?

PHP handles recursion similarly to other programming languages like Java, allowing functions to call themselves. However, PHP has a default recursion limit set in its configuration, which can cause issues when implementing recursive functions that exceed this limit. To solve this issue, you can increase the recursion limit in the php.ini file or rewrite the recursive function to be more efficient and avoid hitting the limit. 

// Increase recursion limit in PHP
ini_set('xdebug.max_nesting_level', 1000);

// Recursive function example
function factorial($n) {
    if ($n <= 1) {
        return 1;
    } else {
        return $n * factorial($n - 1);
    }
}

echo factorial(5); // Output: 120
