(PHP 5, PHP 7)
Gets the number of rows in a result
int mysqli_num_rows ( mysqli_result $result )
Object oriented style
Procedural style
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. For unbuffered result sets, mysqli_num_rows() will not return the correct number of rows until all the rows in the result have been retrieved.
Parameters:
result
Procedural style only: A result set identifier returned by mysqli_query(), mysqli_store_result() or mysqli_use_result().
Returns:
Returns number of rows in the result set.
Note:
If the number of rows is greater than
PHP_INT_MAX
, the number will be returned as a string.
Examples:
Object oriented style
<?php $mysqli = new mysqli("localhost", "my_user", "my_password", "world"); /* check connection */ if (mysqli_connect_errno()) { printf("Connect failed: %s\n", mysqli_connect_error()); exit(); } if ($result = $mysqli->query("SELECT Code, Name FROM Country ORDER BY Name")) { /* determine number of rows result set */ $row_cnt = $result->num_rows; printf("Result set has %d rows.\n", $row_cnt); /* close result set */ $result->close(); } /* close connection */ $mysqli->close(); ?>
Procedural style
<?php $link = mysqli_connect("localhost", "my_user", "my_password", "world"); /* check connection */ if (mysqli_connect_errno()) { printf("Connect failed: %s\n", mysqli_connect_error()); exit(); } if ($result = mysqli_query($link, "SELECT Code, Name FROM Country ORDER BY Name")) { /* determine number of rows result set */ $row_cnt = mysqli_num_rows($result); printf("Result set has %d rows.\n", $row_cnt); /* close result set */ mysqli_free_result($result); } /* close connection */ mysqli_close($link); ?>
The above examples will output:
Result set has 239 rows.
