mysqli_result::$num_rows
mysqli_num_rows
Gets the number of rows in the result set
Description
Object-oriented style
int|string mysqli_result->num_rows ;
Procedural style
int|string mysqli_num_rows(mysqli_result result);
Returns the number of rows in the result set.
The behaviour of
mysqli_num_rows
depends on whether buffered or unbuffered result sets are being
used. This function returns 0
for unbuffered
result sets unless all rows have been fetched from the server.
Parameters
-
result
Procedural style only: A
mysqli_result
object returned bymysqli_query
,mysqli_store_result
,mysqli_use_result
ormysqli_stmt_get_result
.
Return Values
An int representing the number of fetched rows.
Returns 0
in unbuffered mode unless all rows
have been fetched from the server.
If the number of rows is greater than
PHP_INT_MAX
, the number will be returned
as a string.
Examples
Example 7.134 Object-oriented style
<?php
mysqli_report(MYSQLI_REPORT_ERROR | MYSQLI_REPORT_STRICT);
$mysqli = new mysqli("localhost", "my_user", "my_password", "world");
$result = $mysqli->query("SELECT Code, Name FROM Country ORDER BY Name");
/* Get the number of rows in the result set */
$row_cnt = $result->num_rows;
printf("Result set has %d rows.\n", $row_cnt);
Example 7.135 Procedural style
<?php
mysqli_report(MYSQLI_REPORT_ERROR | MYSQLI_REPORT_STRICT);
$link = mysqli_connect("localhost", "my_user", "my_password", "world");
$result = mysqli_query($link, "SELECT Code, Name FROM Country ORDER BY Name");
/* Get the number of rows in the result set */
$row_cnt = mysqli_num_rows($result);
printf("Result set has %d rows.\n", $row_cnt);
The above examples will output:
Result set has 239 rows.
Notes
In contrast to the
mysqli_stmt_num_rows
function, this function doesn't have object-oriented
method variant. In the object-oriented style, use the getter
property.
