Using str_replace, need some help.

[ESCForums_com]

while($sql[$n])
{
	$message .= ($mods[$n-1] != $mods[$n]) ? '<p><b><font size=3>'.$mods[$n].'</font></b><br/>' : '';
	if(!$result = $db->sql_query($sql[$n])) 
	$message .= '<b><font color=#FF0000>[Already added]</font></b> line: '.($n+1).' , '.$sql[$n].'<br />';
	else $message .='<b><font color=#0000fF>[Added]</font></b> line: '.($n+1).' , '.$sql[$n].'<br />';
	$n++;
}
 message_die(GENERAL_MESSAGE, $message); 
?>

how would I apply an str_replace on the $message variable before its shown? The code up top is pulling info from an array.

I want to replace:

"<" with "&lt;"
and
">" with "&gt;"

Thanks!

The fast'n'dirty is way is to use the htmlspecialchars() function (aka htmlentities()).

RTFM on that function at www.php.net for more info...

Thanks for the info anyways, I just got half of what i wanted to do figured out...I just can't get two searchs...

while($sql[$n])
{
$message .= ($mods[$n-1] != $mods[$n]) ? '<p><b><font size=3>'.$mods[$n].'</font></b><br/>' : '';
if(!$result = $db->sql_query($sql[$n]))
$message .= '<b><font color=#FF0000>[Already added]</font></b> line: '.($n+1).' , '.str_replace(">","&gt;",$sql[$n]) .'<br />';
else $message .='<b><font color=#0000fF>[Added]</font></b> line: '.($n+1).' , '.$sql[$n].'<br />';
$n++;

message_die(GENERAL_MESSAGE, $message);
?>

Ahh I cannot believe this, I worked on this small thing for an hour yesterday, and today I figured it out myself in 5 minutes!

I needed to insert this ->

str_replace(">","&gt;",str_replace("<","&lt;",$sql[$n]))

function repl_lt_gt($str) {
$a1 = array("<",">");
$a2 = array("&lt;","&gt;");
for ($x=0;$x<2;$x++) { $str = str_replace($a1[$x], $a2[$x], $str); }
return $str;
}

Yes, that's all very cool.
Just don't understand, why noy use two str_replace consequently:

$a = str_replace('>', '&gt;', $a);
$a = str_replace('<', '&lt;', $a);
echo $a;

And, BTW, htmlentities() is NOT "aka htmlspecialchars()". They are different a lot.
