I’m doing some alerts or reminders in a page using php i have the main table alerts. the alerts depend in many different tables. my question is, if it is safe or is it a good method to have multiple queries for different tables on the same page for example there are about 20 reminders..

//alert 1
query 1 table alerts
if(——){ show alert 1
}
//alert 2
query 2 table alert and voc
if(——){ show alert 2
}
//alert 3
query 3 table alert and falgs
if(——){ show alert 3
}
//alert 4
query 4 table alert and casketss
if(——){ show alert 4
}

and so on….

thanks in advance for your input
