function highcharttable_match_path in HighchartTable 7

Match a path against one or more regex patterns.

A drop-in replacement for drupal_match_path(), this also handles pattern negation through the use of the twiddle/squiggle (~) character.

Adapted from function context_condition_path::match() in the Context module.

Parameters

string $path: The path string to be matched.

string $patterns: String containing a sequence of patterns separated by \n, \r or \r\n. Each pattern will be trimmed of leading spaces. Any pattern that begins with ~ is interpreted as an exclusion and overrides any match amongst patterns. Example: With $patterns = "admin/*\n~admin/reports/visitors", this function will return TRUE for all "admin/*" paths, except "admin/reports/visitors".
