    Awesome!


    Thanks for the great article. I knew of most of them, but not the herefile (<<<) feature. That's excellent!! Thanks again for taking the time to shed light on php's lesser known features.

    Re: missing ... which version?


    I agree that that would have been helpful, but isnce it wasn't included, why don't you check the PHP manual. Just type http://www.php.net/function (replace function with the name of the function in question) to see that manual page for that function. At the top of it you'll find the version info you're seeking. HTH

    What about functions, that are not documented


    I mean "echo" functions, such as FOR and IF inside echo.

    string select


    I am wondering if there is a way to select the href value out of a link tag.

    ex <a href="i want to select this">

    Good information, wrong layout


    I find the contents of the article really useful, but the whimsical chapter headings are a really, really bad idea. They're supposed to save you time by indicating what a given chapter is about, but instead you have to try them at random in the hopes that your whimsical interpretation of them is the same as the author's, which is aggravating when all you need is to find information about, say, string case manipulation.

    documentation? (almost) everything is documented


    Use the function lookup search form at php.net
    [www.php.net] is your friend. Don't be affraid to look in it and to read the most-of-the-time very useful user comments

    <b>echo</b>
    [http://www.php.net/manual/en/function.echo.php]

    <b>for, if, etc...</b>
    [http://www.php.net/manual/en/control-structures.php]

    some answers to echo vs. print


    Like **echo**, **print** is a language construct and does not require parentheses.

    One of the difference between them is that **print** behaves like a function and has a return value:

    $r = print "hello"; //will print "hello" and assign 1 to $r;

    The other one is that you can pass more expression to **echo** (but do not use the parentheses) whereas you can only pass one at a time with **print**:

    $what = "world";<br>
    echo "hello", " ", $what;

    Excellent


    This was just what I was looking for and I found it just before resorting to the manual ;)
    Well written and easy to follow for the begginer.
    Thankyou

    Oh, Thank You!


    I just finished reading String Theory by Vikram Vaswani September 20, 2001 that I found on the web. Thanks so much! It was exactly what I needed, exactly how I wanted it and clear as crystal!
