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! :-)
