sybase_fetch_array — Fetch row as array
This function was REMOVED in PHP 7.0.0.
$result
) : arraysybase_fetch_array() is an extended version of sybase_fetch_row(). In addition to storing the data in the numeric indices of the result array, it also stores the data in associative indices, using the field names as keys.
An important thing to note is that using sybase_fetch_array() is NOT significantly slower than using sybase_fetch_row(), while it provides a significant added value.
result
Returns an array that corresponds to the fetched row, or FALSE
if there
are no more rows.
Note:
When selecting fields with identical names (for instance, in a join), the associative indices will have a sequential number prepended. See the example for details.
Example #1 Identical fieldnames
<?php
$dbh = sybase_connect('SYBASE', '', '');
$q = sybase_query('SELECT * FROM p, a WHERE p.person_id= a.person_id');
var_dump(sybase_fetch_array($q));
sybase_close($dbh);
?>
The above example would produce the following output (assuming the two tables only have each one column called "person_id"):
array(4) { [0]=> int(1) ["person_id"]=> int(1) [1]=> int(1) ["person_id1"]=> int(1) }
