mysqli_result::fetch_array -- mysqli_fetch_array — Fetch a result row as an associative, a numeric array, or both
Nesne yönelimli kullanım
Yordamsal kullanım
Returns an array that corresponds to the fetched row or NULL
if there
are no more rows for the resultset represented by the
result
parameter.
mysqli_fetch_array() is an extended version of the mysqli_fetch_row() function. In addition to storing the data in the numeric indices of the result array, the mysqli_fetch_array() function can also store the data in associative indices, using the field names of the result set as keys.
Bilginize: Bu işlevden dönen alan isimlerinin harf büyüklüklerinde değişiklik yapılmaz.
Bilginize: Bu işlev NULL alanlara PHP
NULL
değerini atar.
If two or more columns of the result have the same field names, the last column will take precedence and overwrite the earlier data. In order to access multiple columns with the same name, the numerically indexed version of the row must be used.

resulttype
This optional parameter is a constant indicating what type of array
should be produced from the current row data. The possible values for
this parameter are the constants MYSQLI_ASSOC
,
MYSQLI_NUM
, or MYSQLI_BOTH
.
By using the MYSQLI_ASSOC
constant this function
will behave identically to the mysqli_fetch_assoc(),
while MYSQLI_NUM
will behave identically to the
mysqli_fetch_row() function. The final option
MYSQLI_BOTH
will create a single array with the
attributes of both.
Returns an array of strings that corresponds to the fetched row or NULL
if there
are no more rows in resultset.
