# @DESCRIPTION:

# inherits that eclass, you must set this manually before inherit.

# Defaults to "yes" and should not be changed in most cases.

# ebuilds have to inherit this eclass unconditionally, but only
# actually use it when (for example) the user has USE=php.

# @ECLASS-VARIABLE: PHP_EXT_S

# bundle the PHP extension. Defaults to ${S}.

# An optional file name of the saved ini file minis the ini extension
# This allows ordering of extensions such that one is loaded before
# or after another.  Defaults to the PHP_EXT_NAME.
# Example (produces 40-foo.ini file):
# @CODE
# PHP_INI_NAME="40-foo"

# for all targets so USE defaults may be necessary.
# Example:
# @CODE
# PHP_EXT_NEEDED_USE="mysql?,pdo,pcre(+)"
# @CODE
#
# The PHP dependencies will result in:
# @CODE
# php_targets_php7-0? ( dev-lang/php:7.0[mysql?,pdo,pcre(+)] )
