Now, please Page Down until the Local ports displayed include the range 10090 10100 to 10093.10103

If Zend Server is not installed, or the ZENDPHP7 ZENDPHP74 Apache instance is not active, ports 1009010100, 1009110101, and 10093 10103 should not be displayed.  In this example, nothing is displayed between Local Ports 8479 and 11279:

Remote           Remote  Local

127.0.0.1          8473  13959  000:30:37  Established

127.0.0.1         23919  54687  +++++++++  Closed     

This indicates ports 1009010100, 1009110101, and 10093 10103 are available (check for 10090, 10091 and 10093 for versions 9.1.x, 2018.x and 2019.x or check for 10080, 10081, and 10083 for versions prior to Version 9).   If Zend Server for IBM i is not installed, it should be safe to install it.  If Zend Server for IBM i is installed, this would indicate that the ZENDPHP7 ZENDPHP74 Apache instance is not active.

This next example shows how the display might look if the ZENDPHP7 ZENDPHP74 Apache instance is active:

Remote           Remote  Local

Notice the first three entries for the ports do not have a Remote Address specified, but just show an asterisk.  If you use option 8 on any of these three, you should see a bunch of ZENDPHP7 ZENDPHP74 jobs on the "Display Jobs Using Connection" display.  The additional entries we see for Local Port 10093 10103 showing a Remote Address of 127.0.0.1 are very temporary, and it is often not possible to enter an option 8 for them before the job is finished.  If you do get into the "Display Jobs Using Connection" display for one of these, it will likely show "(No jobs)", which is normal when this port is used by Zend Server.  This indicates the process using the port is not associated with a job.
