print_r() prints out only 150 elements in array

I have an array $product_urls containing 200 elements.

Problem: When I do a print_r($product_urls), PHP prints out an array containing 150 elements, and the output appears to be truncated because its missing the closing ). I checked the HTML source code generated and it is indeed truncated at the 150th element. count($product_urls) gives 200.

This is puzzling. I'm using a PHP framework called Laravel. Any ideas?

PHP Code

echo "<pre>";
echo count($product_urls);
print_r($product_urls);

Output
