Description:
------------
I have problems executing a sql statement from php7 to a db2 database, here are my configuration data and error:
PHP version:

ERROR:

I try set more memory on php.ini but not work.
Also, I try with set ini_set('memory_limit', '-1'); and dont work.
What can I do to make it work? Any suggestion? I have the same installation in php5.4 and it works perfect, but now I need run it on php7.
