I don't understand xcount().
Instead of xcount(), why not use strlen()?
Say we have 7100 chars
If you step through, first pass
$i = 0
$chunk_count = 2
$start = 0
$final = 3500
$text[] is chars 0-3499
second pass
$i = 1 // from $i++
$chunk_count = 2
$start = 3501 // problem is here - note the endpoint of the last pass in
$text[]?
$final = 3499
$text[] is chars 3501-7000 // what happened to char 3500 itself?
Remember that substr() takes a start point, and an offset - not an endpoint.
So after the first pass, you've read in 0-3499 as is correct, but you have
an extraneous if() clause that inc's your start by one, and then adds 3500.
Drop the second if($start == 0) clause which sets $start to 1.

Subject: [PHP-DB] 'the missing character'
Hi!
Does anyone know of a function in php that will take a chunk of text and
seperate it into 'chunks' preferably returning it in an array?
The reason being is that I have some columns(oracle) that are set to
varchar2(4000) and I have text that is 4000+ AND :-) I cannot change it to
another format.
I was unable to find a chunk maker so I built one.
function chunk_maker($text)
{
// have to count the number of characters, if over 3500 characters
need to split into chunks of 3500 characters
$count = xcount($text);
if($count 3500)
{
$chunk_count = $count/3500;
//need to clean up the $chunk_count by removing the
trailing decimals and
//adding one to the total to make sure we do not loose in
characters
$chunk_count = floor($chunk_count)+1;
$i=0;
$start=0;
while($i != $chunk_count)
{
// err well this helps to make sure we get the
correct amount of characters
if($start == 0)
{
$final = 3500;
} else {
$final = 3499;
}
//now we need to make the chunks and stick them in
an array
$text2[]=substr($text,$start,$final);
// err well this helps to make sure we get the
correct amount of characters
if($start == 0)
{
$start=1;
}
$start=$start+3500;
$i++;
}
} else {
$text2[] = $text;
}
return($text2);
}
function xcount($text)
{
global $debug;
foreach (count_chars($text) as $my_value)
$length=$length+$my_value;
tracker($length);
return($length);
}
If I just failed to find the right functions please let me know, otherwise
please help! :-)
