mysqli_result::$num_rows
mysqli_num_rows
Gets the number of rows in the result set
Description
Object-oriented style
intstring$mysqli_result->num_rows;
Procedural style
intstring mysqli_num_rows(mysqli_result $result
)
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 by mysqli_query, mysqli_store_result,
mysqli_use_result or mysqli_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.
Note:
If the number of rows is greater than PHP_INT_MAX
,
the number will be returned as a string.
Examples
Example #1 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 #2 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:
Notes
Note:
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.
