mysqli::store_result

mysqli_store_result

(PHP 5)

mysqli::store_result -- mysqli_store_result — Transfers a result set from the last query

Description

Object oriented style (method):

mysqli_result store_result ( void )

Procedural style:

mysqli_result mysqli_store_result ( mysqli $link )

Transfers the result set from the last query on the database connection represented by the link parameter to be used with the mysqli_data_seek() function.

Parameters

link: Procedural style only: A link identifier returned by mysqli_connect() or mysqli_init()

Return Values

Returns a buffered result object or FALSE if an error occurred.

Note: mysqli_store_result() returns FALSE in case the query didn't return a result set (if the query was, for example an INSERT statement). This function also returns FALSE if the reading of the result set failed. You can check if you have got an error by checking if mysqli_error() doesn't return an empty string, if mysqli_errno() returns a non zero value, or if mysqli_field_count() returns a non zero value. Also possible reason for this function returning FALSE after successfull call to mysqli_query() can be too large result set (memory for it cannot be allocated). If mysqli_field_count() returns a non-zero value, the statement should have produced a non-empty result set.

Notes

Note: Although it is always good practice to free the memory used by the result of a query using the mysqli_free_result() function, when transfering large result sets using the mysqli_store_result() this becomes particularly important.
