sesam_fetch_array -- Fetch one row as an associative array
Description
array sesam_fetch_array (string result_id [, int whence [, int
offset]])
Returns an array that corresponds to the fetched row, or FALSE if there
are no more rows.
sesam_fetch_array() is an alternative version of sesam_fetch_row(). Instead of storing the data in the
numeric indices of the result array, it stores the data in associative indices, using the field
names as keys.
result_id is a valid result id returned by sesam_query() (select type queries only!).
For the valid values of the optional whenceand offset
parameters, see the sesam_fetch_row() function
for details.
sesam_fetch_array() fetches one row of data from the result associated with the
specified result identifier. The row is returned as an associative array. Each result column is
stored with an associative index equal to its column (aka. field) name. The column names are
converted to lower case.
Columns without a field name (e.g., results of arithmetic operations) and empty fields are
not stored in the array. Also, if two or more columns of the result have the same column names, the
later column will take precedence. In this situation, either call sesam_fetch_row() or make an alias for the column.
SELECT TBL1.COL AS FOO, TBL2.COL AS BAR FROM TBL1, TBL2

A special handling allows fetching "multiple field" columns (which would otherwise all
have the same column names). For each column of a "multiple field", the index name is constructed
by appending the string "(n)" where n is the sub-index of the multiple field column, ranging from 1
to its declared repetition factor. The indices are NOT zero based, in order to match the
nomenclature used in the respective query syntax. For a column declared as:
CREATE TABLE ... ( ... MULTI(3) INT )
|
the associative indices used for the individual "multiple field" columns would be
"multi(1)", "multi(2)", and "multi(3)" respectively.
Subsequent calls to sesam_fetch_array() would return the next (or prior, or n'th
next/prior, depending on the scroll attributes) row in the result set, or FALSE if
there are no more rows.

Example 1. SESAM fetch array
<?php
$result = sesam_query ("SELECT * FROM phone\n".
" WHERE LASTNAME='".strtoupper($name)."'\n".
" ORDER BY FIRSTNAME", 1);
if (!$result) {
... error ...
}
// print the table:
print "<TABLE BORDER>\n";
while (($row = sesam_fetch_array ($result)) ∓∓ count ($row) > 0) {
print " <TR>\n";
print " <TD>".htmlspecialchars ($row["firstname"])."</TD>\n";
print " <TD>".htmlspecialchars ($row["lastname"])."</TD>\n";
print " <TD>".htmlspecialchars ($row["phoneno"])."</TD>\n";
print " </TR>\n";
}
print "</TABLE>\n";
sesam_free_result ($result);
?>
