WS, phpdoc, and you :)

Hi- Looks good except a new nitpicky notes: a) Always check unified diffs before submit as to not miss any Whitespace changes. Makes it more difficult to see what actually changed. b) Check our coding standards, we always put the braces like: if () { } else { } c) Typo: spefic d) We always use && and not AND although not a big deal Regards, Philip On Tue, 8 Apr 2003, Sean Coates wrote: > sean Tue Apr 8 07:31:40 2003 EDT > > Modified files: > /phpdoc/en/faq html.xml > Log: > Added Javascript variable example (bug 14527) > > > Index: phpdoc/en/faq/html.xml > diff -u phpdoc/en/faq/html.xml:1.19 phpdoc/en/faq/html.xml:1.20 > --- phpdoc/en/faq/html.xml:1.19 Fri Jan 24 14:46:14 2003 > +++ phpdoc/en/faq/html.xml Tue Apr 8 07:31:40 2003 > @@ -1,5 +1,5 @@ > <?xml version="1.0" encoding="iso-8859-1"?> > -<!-- $Revision: 1.19 $ --> > +<!-- $Revision: 1.20 $ --> > <chapter id="faq.html"> > <title>PHP and HTML</title> > <titleabbrev>PHP and HTML</titleabbrev> > @@ -190,7 +190,7 @@ > ]]> > </programlisting> > This produces two arrays, MyArray and MyOtherArray, that gets sent > - to the PHP script.
