You forgot an opening bracket, and need to quote the regex, like
if (ereg('[^0-9]', $num))
print That's not a number!;
I think I'm missing something here but while the regex might be correct,
don't you think the print ... part is incorrect?
I mean, _negative_ numbers are numbers, no?
Wouldn't it be better just to use is_int() or is_numeric()?

[PHP] Escaping characters won't work
Hello, I'm running Apache 1.3.26, PHP 4.0.5 and WinXPpro. My problem is as follows: Try to execute this code: if (ereg[^0-9], $num)) print That's not a number!; result: parsing error, expects ')' on the if-line. Have also tried other expressions where I escape characters. They won't work. When I write: echo HELLO \n; echo WORLD; I get: HELLO WORLD (on one line!?) Anyone know what's wrong? Do I need to install an extension?

You need to tell the browser to create a newline when displaying HTML:
echo HELLObrWORLD
will look identical to
echo HELLObr\nWORLD
You can also use the nl2br() function to convert all newlines to a line break:
echo nl2br(HELLO\nWORLD);
If you display preformatted text you'll see the linebreak:
echo preHELLO\nWORLD/pre;

No.

have tried sticking the \ in front of the # (pound) and the = (equal) -- not
out of any reason, but more out of frustration. I have been sticking
dropdown menu in inc files with no troubles, but this is the first table
I've tried to stick in there. I'm trying not to ask questions here until
after trying to find an answer in PHP.net, but I've had no luck on this one.

table width=\"90%\" border=\"0\" cellspacing=\"0\" cellpadding=\"0\"
align=\"center\"
tr bgcolor=\"#ebebd6\"

Why you put HTML like this inside PHP code tag? If you need HTML.
Try this
?php
if ($var === TURE) {
?
h1 $var is true /h1
?php
}
else {
?
h1 $var is false /h1
?php
}
?

My previous post is a bit misleading. ""Wade"" [EMAIL PROTECTED] wrote in message 9c6dcb$h8e$[EMAIL PROTECTED]">news:9c6dcb$h8e$[EMAIL PROTECTED]... Aside from " (quotes), which HTML characters should be preceded with a \ (backslash) to avoid parsing errors? No and Yes. NO: You don't have to escape PHP special characters in HTML. YES: You need to escape PHP special characters in string. (Generally speaking) I have the following, which I have in an .inc file outside my web root.

You cannot write HTML like this in PHP code. You can write HTML in conditional statement as my previous post.

[PHP] Escaping Characters - URL Encoding.
H-
I've been able to escape the 'space' character in a variable so it can
be safely passed through a URL but I'm having trouble finding anything
that works for escaping the '' ampsand.
Here is a snippet of code.
$topic = Aerospace Commercial Space;
$link_value = str_replace(, '%26', $topic);
$link_value = str_replace(' ', '%20', $topic);
Here's the strange part.
If the ampersand replace is in front of the space replace the space
replace gets done but the ampersand doesn't.
If the ampersand replace is done after the space replace the
ampersand get's replaced but the spaces do not.
So for the code above the %20 was replaced but the remained .
I split the lines up for simplicity. Is that's what's causing the
problems?
What am I missing here?
Very confusing.
Thanks for any info any one might have on this.
Thoughts, Comments, Anecdotes?

This should be
$link_value = str_replace(, '%26', $topic);
$link_value = str_replace(' ', '%20', $link_value);
Anyway, this is this wrong way to go about it.
This line
$link_value = rawurlencode($topic);
will do the whole job.

php.net/urlencode
as for your code:
$topic = Aerospace Commercial Space;
$link_value = str_replace(, '%26', $topic);
$link_value = str_replace(' ', '%20', $topic);
You are using $topic both times. Your second line should be:
$link_value = str_replace(' ', '%20', $link_value);
