How to execute script on curl output?

Question

PHP

People, help with solving the problem:
There is a certain script on a remote site: example.com/script.php
By executing it with the #curl example.com/script.php command, I get a certain array of data.
How to make it so that if this array contains a certain sequence of characters, for example "Privet Vasya!", a console command in bash is executed?

curl example.com/script.php | grep -q 'Hello Vasya!' && somecommand
This is in its simplest form.
