mysql_fetch_array — Fetch a result row as an associative array, a numeric array, or both

Uyarı

This extension was deprecated in PHP 5.5.0, and it was removed in PHP 7.0.0. Instead, the MySQLi or PDO_MySQL extension should be used. See also MySQL: choosing an API guide and related FAQ for more information. Alternatives to this function include:

Açıklama

mysql_fetch_array ( resource $result [, int $result_type = MYSQL_BOTH ] ) : array

Returns an array that corresponds to the fetched row and moves the internal data pointer ahead.

Değiştirgeler

sonuç

resource türünde sorgu sonucu. Bu sonuç bir mysql_query() çağrısının sonucudur.

result_type

The type of array that is to be fetched. It's a constant and can take the following values: MYSQL_ASSOC, MYSQL_NUM, and MYSQL_BOTH.

Dönen Değerler

Returns an array of strings that corresponds to the fetched row, or FALSE if there are no more rows. The type of returned array depends on how result_type is defined. By using MYSQL_BOTH (default), you'll get an array with both associative and number indices. Using MYSQL_ASSOC, you only get associative indices (as mysql_fetch_assoc() works), using MYSQL_NUM, you only get number indices (as mysql_fetch_row() works).

If two or more columns of the result have the same field names, the last column will take precedence. To access the other column(s) of the same name, you must use the numeric index of the column or make an alias for the column. For aliased columns, you cannot access the contents with the original column name.

Bilginize: Performance

An important thing to note is that using mysql_fetch_array() is not significantly slower than using mysql_fetch_row(), while it provides a significant added value.
