PHP long article paging function with usage method, paragraphs will not be divided, pages will be turned at the bottom_PHP tutorial

Copy code The code is as follows:

{
global $expert_id;
$PageLength = 2000; //Number of words per page
$CLength = strlen($content);
$PageCount = floor(($CLength / $PageLength)) + 1; //Calculation Number of pages
$PageArray=array();
$Seperator = array("n","r",".","!","?",";",",","" ","'"); //delimiter

//echo "Page count: ".$PageCount."
";
//echo "Length: ".$CLength. "


";
//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)
{

$output=" (continued from section ".($ page-1)."page）n".$output;
}

echo str_replace("n","
