You could try with echo -e to have the newline recognized. Though it would be ok to see how you assign/fill this array. Anyway here is a general example:
i have a file,like
1 3
4 5
6 7
8 9
i want to save it into an array.
and then i want to get every element, because i want to use them to calculate. for example: i want to calculate 1 + 3.
but i cannot reach my goal.

pg_fetch_assoc
PG_FETCH_ASSOC(3)PG_FETCH_ASSOC(3)pg_fetch_assoc - Fetch a row as an associative arraySYNOPSIS
array pg_fetch_assoc (resource $result, [int $row])
DESCRIPTION pg_fetch_assoc(3) returns an associative array that corresponds to the fetched row (records).
pg_fetch_assoc(3) is equivalent to calling pg_fetch_array(3) with PGSQL_ASSOC as the optional third parameter. It only returns an associa-
tive array. If you need the numeric indices, use pg_fetch_row(3).
Note
This function sets NULL fields to the PHP NULL value.
pg_fetch_assoc(3) is NOT significantly slower than using pg_fetch_row(3), and is significantly easier to use.
PARAMETERS
o $result
- PostgreSQL query result resource, returned by pg_query(3), pg_query_params(3) or pg_execute(3) (among others).
o $row
- Row number in result to fetch. Rows are numbered from 0 upwards. If omitted or NULL, the 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 #1
pg_fetch_assoc(3) example
<?php
$conn = pg_connect("dbname=publisher");
if (!$conn) {
echo "An error occurred.
";
exit;
}
$result = pg_query($conn, "SELECT id, author, email FROM authors");
if (!$result) {
echo "An error occurred.
";
exit;
}
while ($row = pg_fetch_assoc($result)) {
echo $row['id'];
echo $row['author'];
echo $row['email'];
}
?>
