I have Test your code  this error shows when you already have the DB imported or with some tables with the same name  also the Array error that shows is because you add in in the exec parenthesis  here is the fixed version     lt  php   ENTER THE RELEVANT INFO BELOW  mysqlDatabaseName   test    mysqlUserName   root    mysqlPassword       mysqlHostName   localhost    mysqlImportFilename   dbbackupmember sql     DONT EDIT BELOW THIS LINE   Export the database and output the status to the page  command  mysql -h    mysqlHostName    -u    mysqlUserName    -p    mysqlPassword        mysqlDatabaseName     lt      mysqlImportFilename   output array    exec  command  output  worked   switch  worked       case 0          echo  Import file  lt b gt     mysqlImportFilename    lt  b gt  successfully imported to database  lt b gt     mysqlDatabaseName    lt  b gt            break      case 1          echo  There was an error during import            break      gt
