Example 1925. pg_fetch_row() example

<?php

$conn
= pg_pconnect("dbname=publisher");
if (!
$conn) {
 echo
"An error occured.\n";
 exit;
}

$result = pg_query($conn, "SELECT author, email FROM authors");
if (!
$result) {
 echo
"An error occured.\n";
 exit;

$row = pg_fetch_row($result)) {
 echo

 echo
"<br />\n";

Code Examples / Notes » pg_fetch_row

rtreat2

the mysql way....
$rows = pg_numrows($result);
for ($i=0; $i < $rows; $i++){
   list($foo,$bar) = pg_fetch_row($result,$i);
   print ("$foo , $bar)\n");
}

Note, that when you retrieve some PG boolean value, you get 't' or 'f' characters which are not compatible with PHP bool.

matthew wheeler

Note that the internal row counter is incremented BEFORE the row is retrieved. This causes an off by one error if you try to do:
pg_result_seek($resid,0);
pg_fetch_row($resid);
you will get back the SECOND result not the FIRST.

I wondered whether array values of PostgreSQL are converted to PHP arrays by this functions. This is not the case, they are stored in the returned array as a string in the form "{value1 delimiter value2 delimiter value3}" (See http://www.postgresql.org/docs/8.0/interactive/arrays.html#AEN5389).

I use the following code to assigning query result to an array.
while ($row = pg_fetch_row($result)) $newArray[] = $row[0];
print_r($newArray);

Get downlines, put them into arrays.
function get_downlines($my_code){
global $link;
$sql = "select user_id, name from tb_user where parentcode = $my_code";
$res = pg_query($link,$sql);
if(!$res){
echo "Error: ".$sql;exit();
}
$num_fields = pg_num_fields($res);
$info_rows = 0;
$num_rows = pg_num_rows($res);
while($arr = pg_fetch_row($res)){
      $info_offset  = 1;
    $info_columns  = 0;
while ($info_offset <= $num_fields) {
        $info_elements[$info_rows][$info_columns] = $arr[$info_columns];
        $info_offset++; $info_columns++;
}
$info_rows++;
}
return $info_elements;
}

a way to do this with 2 loops to insert data into a table...
$num = pg_numrows($result);
$col_num = pg_numfields($result);
for ($i=0; $i<$num; $i++) {
 $line  = pg_fetch_array($result, $i, PGSQL_ASSOC);
 print "\t<tr bgcolor=#dddddd>\n";
   for ($j=0; $j<$col_num; $j++){
   list($col_name, $col_value) =each($line);
   print "\t\t<TD ALIGN=RIGHT><FONT SIZE=1 FACE='Geneva'>$col_value</FONT></TD>\n";
   }
 echo "
";
 }
