超越PHP - Exceed PHP: highlight_string

Description

mixed highlight_string ( string str [, bool return])

The highlight_string() function outputs a syntax highlighted version of str using the colors defined in the built-in syntax highlighter for PHP.

If the second parameter return is set to TRUE then highlight_string() will return the highlighted code as a string instead of printing it out. If the second parameter is not set to TRUE then highlight_string() will return TRUE on success, FALSE on failure.

例子 1. highlight_string() example

<?php highlight_string('<?php phpinfo(); ?>'); ?>
The above example will output (in PHP 4):
<code> <?php phpinfo(); ?> </code>
The above example will output (in PHP 5):
<code> <?php phpinfo(); ?> </code>

注: The return parameter became available in PHP 4.2.0. Before this time it behaved like the default, which is FALSE

There are already some functions for numbering and highliting a string
containging PHP sourcecode on this site, but they were buggy or wasted
recouces. I hope this snippet fits your needs.

  function
my_highlight($text){  
       $text2 = stripslashes($text);
      
$split = split("\n", $text2);  
       $mv = count($split); 

	   
	   /*for design reasons */
	   if($mv < 100){
	  
$width = "14";
	   }elseif($mv < 1000){
	   $width =
"22";
	   }elseif($mv < 10000){
	   $width =
"30";
	   }else{
	   $width = "14";
	   }
	
  /*--------------------*/
       echo "<table
bgcolor=\"#90ab83\" cellspacing=\"0\"
width=\"100%\">";  

	   $text2 =
highlight_string($text2, true);  
       for($i = 0; $i < $mv; $i++){
 
           $t = $i + 1;  

           echo
"<tr><td bgcolor=#7C9B6D width=$width><div
align=right><font face=\"verdana\" 
         
size=\"1\">".$t."</font></div></td>";


           if($t < 2)  
           {  
		   echo
"<td style=\"padding-left: 5px\"
rowspan=\"10000\"
valign=\"top\">".$text2."</td>";  
   
       } 

           echo "</tr>";     
       }

	   echo"</table>";
   }
