- Fixes critical mistake in boot.php regarding set_include_path - Fixes minor mistake in text.php regarding strpos order of arguments Note: This change significantly increases Composer running time because Text_Highlither is a PEAR package. I'm already planning to replace it with scrivo/highlight.php.

|
|
* The first parameter to this function should be the list of command-line
|
|
* arguments without the leading reference to the running program.
|
|
*
|
|
* The second parameter is a string of allowed short options. Each of the
|
|
* option letters can be followed by a colon ':' to specify that the option
|
|
* requires an argument, or a double colon '::' to specify that the option
|
|
* takes an optional argument.
|
|
*
|
|
* The third argument is an optional array of allowed long options. The
|
|
* leading '--' should not be included in the option name. Options that
|
|
* require an argument should be followed by '=', and options that take an
|
|
* option argument should be followed by '=='.
|
|
*
|
|
* The return value is an array of two elements: the list of parsed
|
|
* options and the list of non-option command-line arguments. Each entry in
|
|
* the list of parsed options is a pair of elements - the first one
|
|
* specifies the option, and the second one specifies the option argument,
|
|
* if there was one.
|
|
*
|
|
* Long and short options can be mixed.
|
|
*
|
|
* Most of the semantics of this function are based on GNU getopt_long().
