Re: Postgres 8.1.4 + PHP, hangs when querying more than 16

OS: Fedora Core 5
PHP: PHP 5.1.4, PHP 5.1.6, and PHP 4.4.4 (compiled with --with-pgsql and install as binaries using YUM)
Postgres 8.1.4

This scripts works:
---------------------------------------------------------------------------------
<?php
// Connecting, selecting database
$dbconn = pg_connect("host=localhost dbname=database user=web")
or die('Could not connect: ' . pg_last_error());

// Performing SQL query
$query = 'SELECT * FROM foobar limit 16';

$result = pg_query($query) or die('Query failed: ' . pg_last_error());

// Printing results in HTML
echo "<table>\n";
while ($line = pg_fetch_array($result, null, PGSQL_ASSOC)) {
echo "\t<tr>\n";
foreach ($line as $col_value) {
echo "\t\t<td>$col_value</td>\n";
}
echo "\t</tr>\n";
}
echo "</table>\n";

// Free resultset
pg_free_result($result);

// Closing connection
pg_close($dbconn);
?>
---------------------------------------------------------------------------------
This script hangs:

-----------------------------------------------------------------------------------
<?php
// Connecting, selecting database
$dbconn = pg_connect("host=localhost dbname=database user=web")
or die('Could not connect: ' . pg_last_error());

// Performing SQL query
$query = 'SELECT * FROM foobar limit 17';

$result = pg_query($query) or die('Query failed: ' . pg_last_error());


// Printing results in HTML
echo "<table>\n";
while ($line = pg_fetch_array($result, null, PGSQL_ASSOC)) {
echo "\t<tr>\n";
foreach ($line as $col_value) {
echo "\t\t<td>$col_value</td>\n";
}
echo "\t</tr>\n";
}
echo "</table>\n";

// Free resultset
pg_free_result($result);

// Closing connection
pg_close($dbconn);
?>
-------------------------------------------------------------------------------------

The only difference is that in the first we limit to 16 records, in the latter, to 17 (and greater hangs as well). I tried with three different versions of PHP, as mentioned above (PHP 5.1.4, 5.1.6, & 4.4.4) from both Apache and from the command line. Attempted few times each when compiled versions and binary distributions via yum. All behave the same way. All hang above 17 records.

Take care! Babak.

That seems really weird.

If you run those through psql natively what happens?

Hi Chris, Run through the native client everything works fine. I know, its really strange. Any ideas?

Have you tried with pdo?

$pdo = new PDO('pgsql:host=localhost;dbname=database','web');
$query = $pdo->query('SELECT * FROM foobar;');
$query->execute();
$data = $query->fetchAll(PDO::FETCH_OBJ);
print_r($data);

And have you tried not using other peoples packages but downloading
the source and compiling it? I run PHP 5.1.4 and work with very
large data sets, though I've not upgraded to 5.1.6 yet.

Hope this helps,

Gavin

Hi Gavid, Thanks, no I have not tried PDO but I have compiled 3 different versions of PHP from source with similar results as the 3 different versions from binary distribution. Same for Postgres (compiled from source and dropped-in binary stuff) for two different versions.

Thanks again! Babak.

Hello again; I just finished trying the method below with the same results. 16 records work, more than that it hangs!! Thanks for your help. Babak.

Wow I'd say that something is terribly wrong with your machine, or
it's install of pgsql, other than running fedora ;-). Out of
curiosity what's the row size? how many fields and what's the schema
look like?

Yeah, I just dumped the box completely. It was too frustrating. I'm starting over with FreeBSD this time on new hardware.
