Where can I get error messages?

From

I've installed Postgres 7.2.2 on Linux SuSE 8.0 Pro.
From other server (SuSE 8.0 Pro + Apache 2.0.39 + PHP 4.2.2) I'm trying
to get access to Postgres database, using PHP-script:

<html>
<body>
<? $db = pg_connect(...); ?>
</body>
</html>

I've no errors messages both in PHP log and Postgres console, but HTML
page was been generated this script are stoped on <body> tag. Where
can I get error messages? That is possible troubles?

Thank You

Why don't you use the DB::connect instead?

Hi, Jean-Luc.
Can't find any documents about "DB::connect" at www.php.net :(
Give me please any links to that.
And why "pg_connect" does not work properly?
Script ex.:
---- cut ---------
<html>
<body>
<?
printf("Hello, world!<br>");
$s="host=dbserv port=5432 dbname=ll user=postgres password=gecnzr";
if (($db=pg_pconnect ($s))===false) {printf("FALSE! No connection!<br>");}
printf("This is the end of script<br>");
?>
</body>
</html>
--- cut -----------
No errors messages... "Hello, world!<br>" - is the last line in
generated html text :\

with respect, Andrey

This would mean that something is interfering with PHP's standard error
reporting mechanism. Look for set_error_handler in any PHP code you invoke
and check your php.ini for any related directive, as well as any auto-append
or auto-prepend scripts if defined.

So check the pear-doku.

You are using a persistent connection in your example, but anyway,
your code is working for me perfectly.
To get errormessages try out pg_last_error() or pg_result_error().

Here is a sample:

<html>
  <head>
    <title>PostgreSQL PHP Test</title>
  <body>
    <table>
    <?php
    require_once( 'DB.php');

    $userid=...;
    $password=...;
    $dbhost=...;
    $databse=...;

    $db = DB::connect( "pgsql://$userid:$password@$dbhost/$database");
    if( DB::iserror( $db))
      {
      die( "DB:connect " . $db->getMessage());
      }

    $sql = "select * from whatever";
    $q = $db->query($sql);

    if( DB::iserror( $q))
      {
      die( "Query " . $q->getMessage());
      }

    while( $row = $q->fetchRow( ))
      {
      ?>
      <tr><td><?= $row[0] ?> </td>
          <td><?= $row[1] ?> </td>
          <td><?= $row[2] ?> </td>
      </tr>
      <?php
      }
      ?>
     </table>
   </body>
</html>


Make sure that you include /usr/share/pear in the include_path in
php.ini and restart httpd.

Sorry, but this sample doesn't work... :\
if I change phptype "pgsql" in DSN
(pgsql://$userid:$password@$dbhost/$database)
on "mysql", then get error message:"DB Error: connect failed", but
else if phptype=pqsql (as write in sample) nothing happyness and
result html code is:
<html>
    <head>
        <title>PostgreSQL PHP Test</title>
    </head>
    <body>
        <table>

Can you login with the same user and password using pgsql?
Are the database server and webserver running on the same machine?

If the script has stopped at pg_connect there are two things:
 - the database server isnt running
 - the password, login,machine ip you are using arent authorized to connect

Take a look at the log of postgres. For this, i hope you havent sent the
output of the postmaster to /dev/null.
