pg_fetch_assoc
Fetch a row as an associative array
(PHP 4 >= 4.3.0, PHP 5)
array pg_fetch_assoc ( resource result [, int row] )
pg_fetch_assoc() returns an associative array that corresponds to the fetched row (records).
pg_fetch_assoc() is equivalent to calling
pg_fetch_array() with PGSQL_ASSOC as the
optional third parameter. It only returns an associative array.
If you need the numeric indices, use
pg_fetch_row().
This function sets NULL fields to
PHP NULL value.
pg_fetch_assoc() is NOT significantly slower than using pg_fetch_row(), and is significantly easier to use.
Parameters
- result
PostgreSQL query result resource, returned by pg_query(), pg_query_params() or pg_execute() (among others).
- row
Row number in result to fetch. Rows are numbered from 0 upwards. If omitted, next row is fetched.
Return Values
An array indexed associatively (by field name).
Each value in the array is represented as a
string. Database NULL
values are returned as NULL.
FALSE is returned if row exceeds the number
of rows in the set, there are no more rows, or on any other error.
Examples
Example 1922. pg_fetch_assoc() example
<?php
$conn = pg_connect("dbname=publisher");
if (!$conn) {
echo "An error occured.\n";
exit;
}
$result = pg_query($conn, "SELECT id, author, email FROM authors");
if (!$result) {
echo "An error occured.\n";
exit;
}
while ($row = pg_fetch_assoc($result)) {
echo $row['id'];
echo $row['author'];
echo $row['email'];
}
?>
