Continue in while with mysql_fetch_assoc - php

Question

I have a few lines of code, but can't find the right way to use it properly.
$cc = 0;
$tt = 50;
while ($row = mysql_fetch_assoc($result)) {
//building array with values from DB.
if (++$cc < $tt)
continue;
for ($i = 0; $i < $tt; $i++) {
//Work with the array
}
}
Let's say I have 133 results in DB. It'll get first 50 - do something in the for loop, then 50 more, will go thru the for loop again and will stop.
The last 33 results will be untouched.
It'll get them, but cause can't reach 50 will stop and they won't go through the for loop.
My problems is how to "send" them in the loop down there?

Answer 1

Move the for loop in a function and call it after the while loop:
$cc = 0;
$tt = 50;
while ($row = mysql_fetch_assoc($result)) {
//building array with values from DB.
if (++$cc < $tt) continue;
work_with_array($array);
}
if($cc) work_with_array($array);
function work_with_array($array) {
for ($i = 0; $i < count($array); $i++) {
//Work with the array
}
}

Answer 2

Try this:
$i = 0
while ($row = mysql_fetch_assoc($result)):
if($i < 50):
//Code when $i is less than 50
//Insert code here
elseif($i > 50 && $i < 100):
//Code when $i is more than 50 but less than 100
//Insert code here
elseif($i > 100):
//Code when $i is more than 100
//Insert code here
endif;
$i++;
endwhile;
So all results are going through this loop. If $i is less than 50 (or if the result is less than 50) then some code is executed, or if $i is more than 50 but less than 100 then some different code is executed. Finally if $i is more than 100 then some other code is executed.
Do you understand?

You could try:
$i = 0
while ($row = mysql_fetch_assoc($result) && $i < 100):
if($i < 50):
//Code when $i is less than 50
else:
//Code more than or equal to 50
endif;
$i++;
endwhile;

All the continues inside the loop seem unneccesary. If you're simply trying to process the entire result set and do something in chunks, you can do this
$cc = 0;
$tt = 50;
$result_array = array();
// this will chunk your array into blocks
while ($row = mysql_fetch_assoc($result)) {
//building array with values from DB.
$result_array[intval($cc++/$tt)] = $row;
}
// at this point you should have result_array with indexes:0,1,2 and have subarrays with 50, 50, 33 entries each.
foreach ($result_array as $k=>$sub_array) {
//Work with your sub array
foreach ($sub_array as $one_row)
{
// do something with the row
}
}
I do agree with #Col.Shrapnel though. Why are you creating another array inside the while loop just to go through that array one row at a time to do something? It would've made sense if you send out a batch of data at once (like bulk insert into db, sure) but to loop through again seems odd. Why can't you do the same right in the while loop
