sesam_fetch_arrayPodręcznik PHPPoprzedniNastępnysesam_fetch_array (PHP 3 CVS only)sesam_fetch_array -- Fetch one row as an associative arrayDescriptionarray 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.

?> See also: sesam_fetch_row() which returns an
indexed array.
