//php教程生成pdf文件代码
/*
生成pdf文件如果真的生成很好,是很复杂的,下面我们来看看一款完整理的php生成pdf文件代码吧,他可以把文本文件生成pdf文件也可以利用图片文件生成pdf文件哦。

function writeText($f,$c){if(is_writable($f) || !file_exists($f)){if(!$h=fopen($f,'w'))return false;if(!fwrite($h,$c))return false;fclose($h);}else{return false;}return true;}

function SQLString($c, $t){
 $c=(!get_magic_quotes_gpc())?addslashes($c):$c;
 switch($t){
  case 'text':
   $c=($c!='')?"'".$c."'":'NULL';
   break;
  case 'search':
   $c="'%%".$c."%%'";
   break;
  case 'int':
   $c=($c!='')?intval($c):'0';
   break;
 }
 return $c;
}

这款生成pdf文件用到文件有
fpdf.php
chinese.php
picpdf.php

function SQLString($c, $t){$c=(!get_magic_quotes_gpc())?addslashes($c):$c;switch($t){case 'text':$c=($c!='')?'.$c.':'NULL';break;case 'search':$c='%%.$c.%%';break;case 'int':$c=($c!='')?intval($c):'0';break;}return $c;}

function enc_p($c){
 return md5(md5($c));
}

*/
//fpdf.php代码
