Running PHP file works correctly when SSH'd in but not via cron

Question

I am looking to see if a file exists on the server using a php file as per below by running "php check-backup"

if (!file_exists("../backups/$today/$hour.sql")) {
    echo "File doesn't exist";
} else {
    echo "File exists";
}

When I run this command on directly on the server when ssh'd in it works perfectly but when this is run as a cron job I cannot get it to find the file.

根据Aynber的评论，我检查了使脚本正常工作的完整路径。
