How can this be done in a more efficient manner? I thought about fetching four different sets from the database, meaning 4 different queries, would that be more efficient? I'm thinking it could be done with one loop but but I can't come up with a solution. ![]() So, this means that if I have 1000 entries in the table and 4 different status' that can be checked, it means that there will be 4 loops, each one executing 1000 times. But how do you know which one is the best way to loop your data Apparently, using a for loop is better than. The foreach loop - Loops through a block of code for each element in an array. For example: have this PHP code to implement this ($recipients contains an associative array of the db table): There are many ways we can define a loop in PHP. Below is a code by which you can evaluate the performance of php foreach loop on your server. I need to convert the data into the following XML, depending on the status field. But in reality, there are many types of loops, and both can be used pretty effectively. FOREACH loops are the best loop for iterating through arrays. FOR loops are the best loop for iterating code until a given condition is met. ![]() An alternative method would be to re-group the data. I have a table Recipients in MySQL structured like this: id | email | status An alternative to the PHP FOREACH loop is the PHP FOR loop. 1 Answer Sorted by: 0 I wouldn't worry about the last two lines, it's a common problem when trying to use that method to group data. I just couldn't think of a title that could describe my problem. First off, I know the title is generic and not fitting.
