Fixed up the version checking. Thanks for your help @dschaper. No longer uses the version string as returned, but uses the major and minor version numbers extracted from it, against the minimum of 5.5. Tested against real install of php 7.0, (and the version check logic separately tested against a variety of artificial version numbers, of multiple digits for both major and minor version. - Lesson learned, I'm never trusting bash again) Signed-off-by: Rob Gill <rrobgill@protonmail.com>
