示例1: RenumberNamedCaptures
/**
*
* Gives a unique id to each named capture within a regex.
*
* Reassigns unique identifiers to named captures within a regular expression. The new
* identifiers will have the form "prefix_x", where "prefix" is given by the $prefix
* parameter, and "x" a unique identifier starting from 0.
*
* @param string $pattern
* Regex pattern containing potential named captures to be renamed.
*
* @param array $correspondances
* On output, will hold an associative array whose keys are the new capture group names, and values the old ones.
*
* @param string $prefix
* Prefix string for capture name replacements.
*
* @return string
* Returns the input pattern with all named captures replaced by unique identifiers.
*
* @notes
* This method, along with the GroupNamedCaptures() one, is used by the Preg*Ex methods
* to allow processing of regular expressions having duplicate named captures.
*
