version - Is mysql_connect() usable in PHP 5.6.5

Which is the latest version PHP version, who support mysql_connect()?

I've want to upgrade my PHP version. I've read, that mysql_connect() are deprecated. In all Projects I've use the old mysql_connect(). Can I update to PHP 5.6.5 or is the command in this version removed already?

Uses somebody PHP 5.6.5 with mysql_connect()?

Problem is, that I can't change sooo much Projects in this short time and could only update to the highest version, which support mysql_connect().

Best regards and many thanks!
