|
---|
| 8 | // ccBrowserInfo.php was inspired by browser.php in SourceForge 2.5.
|
---|
| 9 | // Other important influences:
|
---|
| 10 | // sniffer.js from Netscape and
|
---|
| 11 | // phpSniff (http://phpsniff.sourceforge.net/), which offers more
|
---|
| 12 | // functions and greater control, but is too elaborate for my taste.
|
---|
| 13 |
|
---|
| 14 | // ccBrowserInfo does NOT try to be rigorous. Our primary goal is to distinguish
|
---|
| 15 | // between older NN and IE, and between Windows and Mac (and Unix).
|
---|
| 16 | // A useful list of older browser strings is here:
|
---|
| 17 | // http://www.browserlist.browser.org/browser_mappings_list_big.html
|

| 18 | // See also the built-in pull-down list in the phpSniff example:
