How to use the Lookup function PHP long article page function with the use of methods, will not split the paragraph, page to the bottom

Copy CodeThe code is as follows:

{
Global $expert _id;
$PageLength = 2000; Words per page
$CLength = strlen ($content);
$PageCount = Floor (($CLength/$PageLength) + 1; Count pages
$PageArray =array ();
$Seperator = Array ("\ n", "\ R", ". ","！ ","？ ","；","，","”","'"); Delimited symbols
echo "pages:". $PageCount. "
";
echo "Length:". $CLength. "


";
The Strpos () function returns the position of the first occurrence of a string in another string
if ($CLength < $PageLength)
{
Echo $content;
}else{
$PageArray [0]=0;
$Pos = 0;
$i = 0;
First page
for ($j =0; $j {
echo $Seperator [$j];
$Pos =strpos ($content, $Seperator [$j], $PageArray [$i]+1900);
while ($Pos > 0 && $Pos < ($i + 1) * $PageLength && $Pos > $i * $PageLength)
{
$PageArray [$i] = $Pos;
$Pos = Strpos ($Pos + $PageLength, $content, $Seperator [$j]);
}
if ($PageArray [$i]>0)
{
$j = $j + sizeof ($Seperator) + 1;
}
}
//---
for ($i =1; $i < $PageCount-1; $i + +) {
for ($j =0; $j {
echo $Seperator [$j];
$Pos =strpos ($content, $Seperator [$j], $PageArray [$i -1]+1900);
while ($Pos > 0 && $Pos < ($i + 1) * $PageLength && $Pos > $i * $PageLength)
{
$PageArray [$i] = $Pos;
$Pos = Strpos ($Pos + $PageLength, $content, $Seperator [$j]);
}
if ($PageArray [$i]>0)
{
$j = $j + sizeof ($Seperator) + 1;
}
}
}
--Last page
$PageArray [$PageCount -1]= $CLength;
$page = 2;
if ($page ==1)
{
$output =substr ($content, 0, $PageArray [$page -1]+2);
}
if ($page >1 && $page <= $PageCount)
{
$output =substr ($content, $PageArray [$page -2]+2, $PageArray [$page -1]-$PageArray [$page-2]);
$output = "(prev.)." ($page-1). " page) \ n ". $output;
}
echo str_replace ("\ n", "
", $output);
if ($page = = $PageCount)
Return $output =substr ($content, $PageArray [$page -2]+2, $PageArray [$page -1]-$PageArray [$page-2]);
if ($PageCount >1)
{
echo "

";
echo "". $page. " /". $PageCount." Page ";
if ($page >1)
echo "Prev";
Else
echo "Prev";
for ($i =1; $i <= $PageCount; $i + +)
{
echo "[". $i. "]";
}
if ($page < $PageCount)
echo "Next page";
Else
echo "Next page";
echo " ";
}
}
}?>

$c
$current =$_request[' page_t '];
$result =ff_page ($content 1, $current);
echo $result;
