Show summary if php loop? - php

Question

I have a loop that looks like this:
/* For Loop for all sheets */
for($i=0;$i<$totalSheet;$i++) {
$Reader->ChangeSheet($i);
foreach ($Reader as $Row) {
//variables here
$query = "INSERT INTO schools (
//code here
)";
if ($mysqli->query($query) === TRUE) {
echo "<br> New record created successfully <br>";
} else {
echo "Error: " . $query . "<br>" . $mysqli->error;
}
}
}
How do I turn this:
if ($mysqli->query($query) === TRUE) {
echo "<br> New record created successfully <br>";
into a code that will show something like:
XX inputted successfully
{list of schools with ID listed here}
XX not inpputed due to errors
{list of schools not inputted}
Would like to see a simple summary of the entire loop rather than seeing a repeated result of each loop that occurred.

Answer 1

Collect all the information you want in variables, and print them at the end.
$success = $fail = "";
$success_count = $fail_count = 0;
for($i=0;$i<$totalSheet;$i++) {
$Reader->ChangeSheet($i);
foreach ($Reader as $Row) {
//variables here
$query = "INSERT INTO schools (
//code here
)";
if ($mysqli->query($query)) {
$success .= "<li>" . $Row['school_name'] . "</li>";
$success_count++;
} else {
$fail .= "<li>" . $Row['school_name'] . "</li>";
$fail_count++;
}
}
}
echo $success_count . " inputted successfully:<br><ul>" . $success . "</ul>";
echo $fail_count . " not inputted due to errors:<br><ul>" . $fail . "</ul>";
Replace $Row['school_name'] with whatever the correct variable is for the school name in your data.
