Mysqli_query first parameter takes the connection handle while the second parameter takes your SQL query. To answer your question, are you trying to display all the results from the query or just the sum? |

nicolas247: Echo the results in a html table , Google it to see examples. Modified: Check out this link, it should give you an idea. http://stackoverflow.com/questions/14430174/use-php-to-display-mysql-results-in-html-table |

It's a bad practice to echo result from a function, rather use return. Urine: |

Adesege: Baba, all I did was to give him an idea of how to go about it, did you see the "Google" part? It was for him to get his search right. If you feel you have a better answer, help the young man out. |

I take it you've gotten all the database connections part right so I'm going to leave that part as is. Rather than using an SLQ SUM in your query it makes more sense do an SQL SELECT of the required row (in this case total_ded) and return the values as an array. You can then Loop through the array and display the necessary table. Finally sum the array and equally display the sum. Here's what the code will look like <?php public funtion get_all_ded() |

kudaisi: hmm..nice..but won't use a foreach on a large dataset (performance wise ) and would check falsity of $all_feds before displaying the table |

jacob05:Agreed, but I'm not trying to build his entire application for him. I only meant for the code to be used as guide. But it's worth mentioning. |

Mysqli_fetch_array() requires two argument and not one |
