PLease HELP!!! Entity

[wheels979]

Can anyone tell me what's wrong with this code..? All's I need my script to do is cycle thru a given string and turn any ASCII characters greater than 127 into HTML entities:

////////////////START////////////////////

$trans=get_html_translation_table(HTML_SPECIALCHARS);

for($j=0; $j<= strlen($string); $j++){

//cycle through each character in a string & count the # of opening and closing brackets

$lessthan= substr_count($string[$j], "<");
$greatthan= substr_count($string[$j], ">");

if($lessthan != 0){ ++$lesscount;
}

if($greatthan != 0){ ++$greatcount;
}
$stat=$greatcount + 1;

if (ord($string[$j]) > 127 && $stat != $lesscount){

/
If the ASCII value of the current character is > than 127 it is a special character. Translate the entity reference for the character and put it back into the string.
/
$fixstring .= strtr($string[$j], $trans);
}else{

//Else just place the character back into the string.
$fixstring .= $string[$j];
}

/////////End///////////

Strtr() only replaces single characters with single characters. For more general replacements, str_replace() would be needed.

I suspect that replacing characters with ASCII code >127 with their numeric equivalents could be done with one line:

$text = preg_replace("/([\x7f-\xff])/e", "'&#'.ord('\\1').';'", $text);

If you have a table of HTML character entites handy, then use that first (str_replace() can take arrays as arguments and do all the replacements with the one call), then if that preg_match() call is correct, it will mop up any characters that are left.
