Install php7 support to run php script on RAK7258

Hello,
i am using the RAK7258 with latest firmware downloaded from here: https://downloads.rakwireless.com/en/LoRa/Indoor-Gateway-RAK7258/Firmware/
I am trying to install a php script that we need to be running, that gets incoming http requests that we set in the “Integrations” tab of application properties, but appearently the php7 support is not installed. By trying to install it, i first perform a opkg update but i am receiving a lot of errors:

How can i install the php7 support to be able to run my script?
