Обсуждение: first steps in PhP and PostgreSQL
X-No-Archive: true
Hi,
I'm sure that it's a typo or something, but as I'm getting into PhP and PostgreSQL for the first time, I can't be sure.
I have a db, called 'cdi' ..
A 'SELECT * FROM stock;' gets me this in psql ..
cdi=> SELECT * from stock ;
-[ RECORD 1 ]-+-------------------------------
stock_ids | 1
isbn_no | 10101010
code_livre | 23455
titre | toto goes to Hollywood
editeur | editions toto
collection | collection toto
auteur_nom | smith
auteur_prenom | john
matiere | ang
media_type | li
-[ RECORD 2 ]-+-------------------------------
stock_ids | 2
isbn_no | 10536278
code_livre | 24874
titre | toto comes back from Hollywood
editeur | editions baba
collection | collection toto
auteur_nom | martin
auteur_prenom | peter
matiere | fre
media_type | dvd
-[ RECORD 1 ]-+-------------------------------
stock_ids | 1
isbn_no | 10101010
code_livre | 23455
titre | toto goes to Hollywood
editeur | editions toto
collection | collection toto
auteur_nom | smith
auteur_prenom | john
matiere | ang
media_type | li
-[ RECORD 2 ]-+-------------------------------
stock_ids | 2
isbn_no | 10536278
code_livre | 24874
titre | toto comes back from Hollywood
editeur | editions baba
collection | collection toto
auteur_nom | martin
auteur_prenom | peter
matiere | fre
media_type | dvd
So the db is populated. I now do this in a file called base.php ..
<?php
pg_connect ("dbname=cdi user=cdi password=toto") or die
("Couldn't Connect: ".pg_last_error());
$query="SELECT * FROM stock";
$query=pg_query($query);
("Couldn't Connect: ".pg_last_error());
$query="SELECT * FROM stock";
$query=pg_query($query);
// start the output
while($row=pg_fetch_array($query,NULL,PGSQL_ASSOC)) {
echo "Title: ".$row['isbn_no']."<br />";
echo "blah ".$row['code_livre']."<br />";
}
echo "Title: ".$row['isbn_no']."<br />";
echo "blah ".$row['code_livre']."<br />";
}
?>
I copy that file to my apache server, in php_experimental/base.php and access it via a browser.
I don't get an error message. I instead get a blank page.
Your advice would be welcome.

Check the applicable php.ini for where error messages are being sent to. It's typical on production servers to configure PHP to only send errors to syslog, or a file, which usually means they end up in httpd-error.log. When developing, it's usually more convenient to have errors sent to the browser, which is what it seems you were expecting. -- Bill Moran Collaborative Fusion Inc.

I instead get a blank page. Check apache's error log. If you can't figure it out then, better place to ask further questions would be php-general@lists.php.net. -- How many Vietnam vets does it take to screw in a light bulb? You don't know, man.
