protected function PHPUnit_Util_PHP::getPhpBinary

Returns the path to a PHP interpreter.

PHPUnit_Util_PHP::$phpBinary contains the path to the PHP interpreter.

When not set, the following assumptions will be made:

1. When PHPUnit is run using the CLI SAPI and the $_SERVER['_'] variable does not contain the string "PHPUnit", $_SERVER['_'] is assumed to contain the path to the current PHP interpreter and that will be used.

2. When PHPUnit is run using the CLI SAPI and the $_SERVER['_'] variable contains the string "PHPUnit", the file that $_SERVER['_'] points to is assumed to be the PHPUnit TextUI CLI wrapper script "phpunit" and the binary set up using #! on that file's first line of code is assumed to contain the path to the current PHP interpreter and that will be used.

3. When the PHP CLI/CGI binary configured with the PEAR Installer (php_bin configuration value) is readable, it will be used.

4. The current PHP interpreter is assumed to be in the $PATH and to be invokable through "php".
