I used some of your code, but try this variant on for size.
plaintext
?php
error_reporting(E_ALL);
ini_set('display_errors', 1);
$dummyData = DATA
html
body
h1{:seg 'title':}/h1
h1{:seg 'title' cache:}/h1
/body
/html
DATA;
# For arguments sake, I'll provide the whole code snippet...
$fSegRegEx = |\{:(seg) \'([a-z0-9\-\_]{3,})\'\s?(cache)?:\}|i;
preg_match_all($fSegRegEx, $dummyData, $faSegMatches, PREG_SET_ORDER);
print_r($faSegMatches);
?
Not sure what your input is going to be (HTML, XML, etc...) so I used
HTML
Anyways, output from the above code is this:
plaintext
Array
(
[0] = Array
(
[0] = {:seg 'title':}
[1] = seg
[2] = title
)
[1] = Array
(
[0] = {:seg 'title' cache:}
[1] = seg
[2] = title
[3] = cache
)
)
Hope this starts you down the right path.

If the number of semi-colons is fixed, then explode will do the trick.
$foo = 'Silver Small Corp;X^%\n#\n'; $bar = explode(';',
$foo); echo $bar[0];
However if the number of semi-colons is not fixed, then substr in
conjunction with strpos will do the trick.
$foo = 'Silver Small Corp;X^%\n#\n'; $bar = substr($foo, 0,
strpos($foo, ';')); echo $bar;

explode on this first: '^% -'

If you really want a regex.. something like:
preg_match_all('/\s*([^;]+);{5}([^^]*)^/U', $str, $matches);
var_dump($matches);
And you'll have an array of field = values (excuding the Coords field).
I do wonder why this is stored in the db like this.

The above replaces any groups of 2 or more blanks (newlines, spaces, tabs) with a

Is there an easy way to replace them with EITHER a space or a newline, depending on

I.e. bb would be replaced with b, but bnbn would be replaced

RE: [PHP] Reg ex help-Removing extra blank spaces before HTML output
using \n as your replacement text will do ithowever, if you want a
newline in the html, then you'll want br...
and as far as the advanced replace, make an array of search patterns, in
this case two.
your first pattern will be /[ ]+\n+[ ]+/ with a replacement of a single
newline...then the second will be the previous regex.check out php.net
for help with syntax and using arrays with preg_* functionsthe first
should catch all situations of a series of spaces [with at least one newline
in between them] and substitute a newline.
check out mastering regular expressions as well.its worth the money

RE: [PHP] Reg ex help-Removing extra blank spaces before HTML output
second issue first:
one call to preg_replace...if you check out php.net/preg_replace, you'll see
what i mean...use arrays...
and as long as you have them ordered in the right way, it'll execute them in
that order, so by the time the \s replace comes up all your 'bbbnbb' will be
fixed...problem then is that those newlines would get caught by the \s and
get switched to spaces...so, if you want them to stay, then use [ ] to
represent a space instead of \s...might want [ \t] to catch tabs as well...
first issue: hard to see whats going on, but check your syntax. i just ran
this;
$text = this is some text with a newline in it right here \n there it
was;
echo $text;
echo 'br';
echo preg_replace(/[ ]+\n+[ ]+/,\n,$text);
and it made the substitution fine.

Using \n (either in single or double quotes) resulted in actual 'backslash
n' being all over my output, instead of newlines. Hence, my inquiry.
your first pattern will be /[ ]+\n+[ ]+/ with a replacement of a single
newline...then the second will be the previous regex.check out php.net
for help with syntax and using arrays with preg_* functionsthe first
should catch all situations of a series of spaces [with at least one
newline
in between them] and substitute a newline.
Thanks, sounds about right. The second pattern (which sometimes includes
getting rid of newlines) won't clobber the results of the first pattern?
And are you suggesting two separate calls to the preg* function? It sounds
like you are, if each of the two patterns also has a unique replacement
string.
Thanks a lot!

One more thing:
How do I replace with newline instead of a space? I read through the
manuals but couldn't grasp how to do this. \n didn't cut it.
And, more advanced -
The above replaces any groups of 2 or more blanks (newlines, spaces, tabs)
with a single blank.
Is there an easy way to replace them with EITHER a space or a newline,
depending on whether any newlines were present in the input?
I.e. bb would be replaced with b, but bnbn would be
replaced with n.

RE: [PHP] Reg ex help-Removing extra blank spaces before HTML output
OK, this time the \n worked. The only thing I changed was using / delimiters instead of | delimiters in the search string. No idea if/why that would affect anything in the replacement string. Anyway, I finally came up with exactly what I wanted: preg_replace(array(/\s*\n+\s*/, /[ ]+/), array(\n, ), $input); All padding (defined as any series of spaces, newlines and sometimes tabs) is removed from $input, but always leaving at least a space or a newline in its place. If there were any newlines in the padding, then a newline is left. If there weren't, then a space is left. Thanks for the help!

cool, glad you got it working...if you think there's a bug with using / and | you might want to see if you can replicate the problem, and if its really a bug, submit it...my guess is that it was just a typo or something jack -Original Message- From: Ken [mailto:[EMAIL PROTECTED]] Sent: Thursday, December 06, 2001 5:13 PM To: Jack Dempsey; PHP list Subject: RE: [PHP] Reg ex help-Removing extra blank spaces before HTML output OK, this time the \n worked.

Re: [PHP] Reg ex help-Removing extra blank spaces before HTML output
Hello,
The example Jack gave you will clear up spaces well, though to get both
newlines and spaces into one:
$input = preg_replace(/([ ]|\n){1,}/, \\1, $input);

I want to remove all superfluous blank spaces before I sent my HTML
output,
to make the output smaller.
So I'd like to take $input, replace any number of blank space or newlines
that are consecutive and replace them with a single blank.
I.e. I will list a blank space as b and a newline as n:
If input is: bTEXTHEREbbbnnnbnMOREbEVENMORE
Then output should be: bTEXTHEREbMOREbEVENMORE
I imagine this would be handled by a simple regular expression call, but
I'm
no pro with them yet.
Any help?

RE: [PHP] Reg ex help-Removing extra blank spaces before HTML output
true...he didn't mention newlines though so i left those out...also, since
PHP 4.0.4 $n [meaning $1], being the preferred one. you also don't need
double quotes and since + means 1 or more, i'd save myself some typing
$input = preg_replace('/(\s|\n)+/',$1,$input);
of course since you're now matching and replacing it'll take longer than a
straight substitution, although i doubt the files you're scanning are big
enough to notice

RE: [PHP] Reg ex help-Removing extra blank spaces before HTML output
actually it does... james' solution will work but I forgot to mention a
\s is whitespace, not a space, therefore it will get tabs, newlines, and
spaces. look at http://www.cs.tut.fi/~jkorpela/perl/regexp.html
\s matches any whitespace character (space, tab, newline)
therefore my suggestion works:
$t = preg_replace('/\s+/',' ',$text);
its quicker to code, easier to understand, and will run faster because
it doesn't have to match and remember or do alternation...

Re: [PHP] Reg ex help-Removing extra blank spaces before HTMLoutput
One way to do it is:
$NewString = ereg_replace('[[:space:]]+', ' ', $String);
There are also ways to do it with preg functions that are slightly
more efficient; see the pcre docs. And, the standard (AFAIK)
reference book for regular expressions is O'Reilly's 'Mastering
Regular Expressions'; a worthwhile purchase.
