32 SWIG and PHP

In this chapter, we discuss SWIG's support of PHP. SWIG currently supports -generating wrappers for PHP7. Support for PHP5 was removed in SWIG 4.0.0 -and support for PHP4 was removed in SWIG 1.3.37. +generating wrappers for PHP7 and PHP8. Support for PHP5 was removed in SWIG +4.0.0 and support for PHP4 was removed in SWIG 1.3.37.

-Currently any PHP7 release should work. +Currently any PHP7 or PHP8 release should work.
