Code _php tutorial for turning RTF files into HTML and displaying them in a Web page

Code that converts RTF files to HTML and displays them in a Web page
It works like this, upload an RTF file, and then turn it into HTML to show it, the code is a bit complicated, Teaman still have to study, as if the Chinese version is a bit problematic.



if (! ( $userfile)) {
?>



Exit
}
function Processtags ($tags, $line) {
$html = "";
Global $color;
Global $size;
Global $bullets;
Remove spaces.
$tags = Trim ($tags);
Found the beginning of the bulleted L
Ist.
if (Ereg ("\\\pnindent", $tags)) {
$html. = "

• ";
  $bullets + = $line;
  $tags = ereg_replace ("\\\par", "", $tags);
  $tags = Ereg_replace ("\\\ (tab)", "", $tags);
  }
  if ($line-$bullets = = 0) {
  $tags = ereg_replace ("\\\par", "", $tags);
  }
  ElseIf ($line-$bullets = = 1) {
  if (Ereg ("\\\pntext", $tags)) {
  $html. = "
• ";
  $tags = ereg_replace ("\\\par", "", $tags);
  $tags = Ereg_replace ("\\\ (tab)", "", $tags);
  $bullets + +;
  }
  else {
  $html. = "

";
$bullets = 0;
}
}
Convert Bold.
if (Ereg ("\\\b0", $tags)) {$html. = ""; }
ElseIf (Ereg ("\\\b", $tags)) {$html. = " "; }
Convert Italic.
if (Ereg ("\\\i0", $tags)) {$html. = ""; }
ElseIf (Ereg ("\\\i", $tags)) {$html. = ""; }
Convert underline.
if (Ereg ("\\\ulnone", $tags)) {$html. = ""; }
ElseIf (Ereg ("\\\ul", $tags)) {$html. = ""; }
Convert alignments.
if (Ereg ("\\\pard\\\qc", $tags)) {$html. = "";}
ElseIf (Ereg ("\\\pard\\\qr", $tags)) {$html. = "";}
ElseIf (Ereg ("\\\pard", $tags)) {$html. = "";}
Remove \pard from the tags so it does
N ' t get confused with \par.
$tags = ereg_replace ("\\\pard", "", $tags);
Convert line breaks.
if (Ereg ("\\\par", $tags)) {$html. = "
"; }
Use the color table to capture the fo
NT color changes.
if (Ereg ("\\\cf[0-9]", $tags)) {
Global $fcolor;
$numcolors = count ($fcolor);
for ($i = 0; $i < $numcolors; $i + +) {
$test = "\\\CF". ($i + 1);
if (Ereg ($test, $tags)) {
$color = $fcolor [$i];
}
}
}
Capture font size changes.
if (Ereg ("\\\fs[0-9][0-9]", $tags, $temp)) {
$size = ereg_replace ("\\\fs", "", $temp [0]);
$size/= 2;
if ($size <=) {$size = 1;}
ElseIf ($size <=) {$size = 2;}
ElseIf ($size <=) {$size = 3;}
ElseIf ($size <=) {$size = 4;}
ElseIf ($size <=) {$size = 5;}
ElseIf ($size <=) {$size = 6;}
ElseIf ($size <=) {$size = 7;}
else{$size = 8;}
}
If There was a font color or size cha
Nge, change the font tag now.
if (Ereg ("(\\\cf[0-9)) | | (\\\fs[0-9][0-9]) ", $tags)) {
$html. = "";
}
Replace \tab with alternating spaces
and Nonbreakingwhitespaces.
if (Ereg ("\\\ (tab)", $tags)) {$html. = "";}
return $html;
}
function Processword ($word) {
Replace \ with \
$word = Ereg_replace ("[\\]{2,}", "\ \", $word);
Replace \{with {
$word = Ereg_replace ("[\\][\{]", "\{", $word);
Replace \} with}
$word = Ereg_replace ("[\\][\}]", "\}", $word);
Replace 2 spaces with one space.
$word = Ereg_replace ("", "" ", $word);
return $word;
}
$color = "000000";
$size = 1;
$bullets = 0;
Read the uploaded file into an array.
//
$rtfile = file ($userfile);
$fileLength = count ($rtfile);
Loop through the rest of the array
for ($i = 1; $i < $fileLength; $i + +) {
/*
* * If the line contains "\COLORTBL" then we found the color table.
* * We ' ll have to split it up into each individual red, green, and blue
* * Convert it to hex and then put the red, green, and blue back together.
* * Then store each to an array called Fcolor.
*/
if (Ereg ("^\{\\\colortbl", $rtfile [$i])) {
Split the line by the backslash.
$colors = explode ("\ \", $rtfile [$i]);
$numOfColors = count ($colors);
for ($k = 2; $k < $numOfColors; $k + +) {
Find out how many different colors th
Ere is.
if (Ereg ("[0-9]+", $colors [$k], $matches)) {
$match [] = $matches [0];
}
}

For each color, convert it to hex.
$numOfColors = count ($match);
for ($k = 0; $k < $numOfColors; $k + = 3) {
$red = Dechex ($match [$k]);
$red = $match [$k] < 16? "0$red": $red;
$green = Dechex ($match [$k + 1]);
$green = $match [$k +1] < 16? "0$green": $green;

$blue = $match [$k + 2] < 16? "0$blue": $blue;
$fcolor [] = "$red $green$blue";
}
$numOfColors = count ($fcolor);
}
Or else, we parse the line, pulling O
FF words and tags.
else {
