Errors in PHP/Oracle article

Question

Hi,
There are a few errors in the article dealing with PHP/Oracle located at http://otn.oracle.com/oramag/webcolumns/2003/techarticles/hull_php.html
In the listing for the section called "How to use a database":
- $mycursor ora_open ($conn);
should be
$mycursor = ora_open ($conn);
- echo "RESULT: ora_getcolumn ($mycursor, 0), ora_getcolumn ($mycursor, 1) <br>";
The above is not the way it works in PHP and you won't get the expected results. You can throw variables in between your double-quote delimited strings, but not function calls. You'll have to concatenate the function calls like this:
echo "RESULT: ".ora_getcolumn ($mycursor, 0).", ".ora_getcolumn ($mycursor, 1)."<br>";

Answer 1

Leendert:
Thanks for the comments. The first one is an obvious typo. The second
is a pretty obvious mistake which I missed while reviewing this. Although
PHP will expand variables in a string like that, it will not handle
function calls. How could it. I just tried it, and concatenation works
just as you suggest. Thanks for the corrections, and we updated the
article.
