My father's regular expression, may I ask?

For more information, see config. php $ _ LANG ['new _ arrival '] & nbsp; & nbsp ;=& nbsp; 'New & nbsp; arrivals'; $ _ LANG ['hot _ products'] & nbsp; & nbsp.

Config. php

$ _ LANG ['new _ arrival '] = 'new arrivals ';
$ _ LANG ['hot _ products'] = 'hot products ';
$ _ LANG ['group _ Demos'] = 'group Demos ';
$ _ LANG ['specials '] = "specials ";
$ _ LANG ['after'] = 'contact cu \ 'stomer

';
$ _ LANG ['group _ Demos'] = 'group Demos ';

$ Subject = file_get_contents ("config. php ");
$ Pattern = 'How to write the regular expression here ';
Preg_match_all ($ pattern, $ subject, $ matches );
Print_r ($ matches );

I want to retrieve all the content after the equal sign. how can I write regular expressions?
Note the symbols in the strings after the equal sign (single quotation marks, double quotation marks, escape characters and line breaks must be obtained ).

The result is as follows:
1. 'new arrivals'
2. 'hot products'
3. 'group Demos'
4. "Specials"
5. 'contact cu \ 'stomer
