mysqli_stmt_bind_param stmt->bind_param Binds variables to a prepared statement as parameters Description Procedural style: boolmysqli_stmt_bind_param mysqli_stmtstmt stringtypes mixedvar1 mixed... Object oriented style (method): mysqli_stmt boolbind_param stringtypes mixedvar1 mixed... mysqli_stmt_bind_param is used to bind variables for the parameter markers in the SQL statement that was passed to mysqli_prepare. The string types contains one or more characters which specify the types for the corresponding bind variables Type specification chars Character Description i corresponding variable has type integer d corresponding variable has type double s corresponding variable has type string b corresponding variable is a blob and will be send in packets
If data size of a variable exceeds max. allowed packet size (max_allowed_packet), you have to specify b in types and use mysqli_stmt_send_long_data to send the data in packets. The number of variables and length of string types must match the parameters in the statement.
