RE: How can I use php to connect to a postgresql table

<?php

$dbconn = pg_connect("host=IP ADDRESS dbname=DBNAME user=USERNAME password=PASSWORD")
    or die('Could not connect: ' . pg_last_error());

$query = "SELECT field1 from table";

$result = pg_query($query) or die('Query failed: ' . pg_last_error());
    $num=pg_num_rows($result);
    $i = 0;
      while ($i <$num) {
        while ($line = pg_fetch_array($result)) {
            $field1 = $line['field1'];
$i = $i + 1;
          }

RE: How can I use php to connect to a postgresql table

Dear All,

Thanks MercJones, I have used the code you sent to customise it according to my details but Please  how can I run the PHP program to connect to a PostgreSQL database and select contents of a table and print it on the browser.  I could not run the program. I don't know how to run it or perhaps how to activate the php. I have done some configurations on httpd.conf and php.ini files after installing php. See the program below:

<?php
// Connecting, selecting database
$dbconn = pg_connect("host=138.250.104.227 dbname=rftDatabase user=globus password=globususer");
    

// Performing SQL query
$query = 'SELECT * FROM Criteria_Parameters';
$result = pg_query($query);

// 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);
?>

Is it possible to put the code int a function and then execute the function on a click of a button?

Any help is appreciated
Regards
Gokop
