Q:

PHP more_results() function (with example)

Hi everyone,

I've been working on a PHP project and I came across a function called "more_results()". I'm not quite sure what this function does, so I was hoping someone could help me out.

To give you some context, my project involves executing multiple MySQL statements using mysqli_multi_query(). From what I understand, this function can execute multiple queries at once and store the results. However, I'm not familiar with the "more_results()" function and how it fits into this process.

So my question is, what does the "more_results()" function do in PHP? How does it relate to executing multiple queries using mysqli_multi_query()? Can someone provide an example or explain its usage in a real-world scenario?

Any help or insight would be greatly appreciated. Thank you in advance for your time and assistance!

Best regards,

Hey there,

I've worked with the "more_results()" function in PHP before, so I thought I could share my experience with you.

The "more_results()" function is specifically used in combination with the "mysqli_multi_query()" function to retrieve more results after executing multiple MySQL queries in one go. After executing a multi-query, you can use "more_results()" to check if there are additional result sets available to fetch.

Here's an example that might help illustrate its usage. Let's say you have a scenario where you need to execute three queries at once:

php
$query = "
SELECT * FROM table1;
SELECT * FROM table2;
SELECT * FROM table3;
";

if(mysqli_multi_query($connection, $query)) {
do {
if($result = mysqli_store_result($connection)) {
// Process the current result set
mysqli_free_result($result);
}
} while (mysqli_more_results($connection) && mysqli_next_result($connection));
}


In this example, we execute three queries at once using "mysqli_multi_query()". Inside the "do-while" loop, we call "mysqli_more_results()" to check if there are any remaining result sets to fetch. If there are, we use "mysqli_next_result()" to move to the next result set.

By using "more_results()" and "next_result()", we can efficiently handle multiple queries and retrieve all the results without having to execute them individually.

I hope this clarifies the usage of the "more_results()" function for you. If you have any further questions, feel free to ask!

Hey folks,

I came across this thread while researching the "more_results()" function, and I thought I could provide some additional perspective based on my personal experience.

So, the "more_results()" function in PHP is used when executing multiple queries with the "mysqli_multi_query()" function. It helps determine whether there are additional result sets available after executing a multi-query.

In a recent project I worked on, we needed to fetch data from different tables simultaneously. We used "mysqli_multi_query()" to execute the queries as a single string, and then checked for more results using "more_results()".

Here's a snippet that demonstrates its usage:

php
$query = "
SELECT * FROM table1;
SELECT * FROM table2;
SELECT * FROM table3;
";

if(mysqli_multi_query($connection, $query)) {
do {
// Process the current result set

if(mysqli_more_results($connection)) {
// There are more result sets available, do something here
}
} while (mysqli_next_result($connection));
}


In this example, we execute multiple queries using "mysqli_multi_query()". Inside the loop, we process the current result set and then check if there are more results using "more_results()". If there are, we can perform additional actions specific to those additional result sets.

By leveraging "more_results()", you can handle scenarios where you need to execute multiple queries at once and retrieve results accordingly.

I hope this provides you with an additional perspective on the "more_results()" function. If you have any further questions, feel free to ask!
