Split $string to several smaller chunks of lines

[transparencia]

My string is like this:

 

line 1

line 2

....

line 3453

line 3454

etc...

 

I want to split the string into chunks of 500 lines, do something with those chunks and then reassamble the main $string again. The last chunk doesn't need to be 500 lines it can be less.

 

How can I do it?

something like this will get you started.

 

//text array
$my500lines = array();
$tempText = '';

$string = "line 1
line 2
....
line 3453
line 3454
etc...";

$count = 0;

foreach(preg_split("/(\r?\n)/", $string) as $line){
    $count++;

if ($count == 500)
{
//reset count and temptext
$my500lines[] = $tempText;
$tempText = '';
$count = 0;
}
else
{
$tempText .= $line;
}

}

Might be a little shorter:

 

 

$lines = explode(PHP_EOL, $string);$newchunks = array();while($chunk = array_splice($lines, 0, 500)) {// do something with lines in $chunk$newchunks = array_merge($newchunks, $chunk);}$newstring = implode(PHP_EOL, $newchunks);
