Indeed Ashley, I'm trying to get the TRUE / FALSE value from the boolean
tag.

After reading again, you're absolutely right: strpos does just what I need
it to do: a simple search for a true or false. (Or null, in which case
strpos will be FALSE anyway).

Thanks for your suggestion, I was doing an overkill here.

@Shreyas: thanks for the link! It is very helpful to speed up the testing a
bit!

As far as I can tell, are you just trying to grab the content from the
 tag text node? If it's limited to this basic example, there's
likely not much of a need to use dedicated DOM functions, but consider
using them if you need to work on more complex documents.

If you are just trying to determine if the value is indeed true or false
and nothing else, then a regex could be overkill here. As you only need
to check two values, consider:

if(strpos($xml, 'true') || strpos($xml, 'false'))
{
// text node content is OK
}
else
{
// bad, bad input, go sit in the corner
}

Camilo,

What exactly are you trying to achieve? Meaning:

if (true)
   do this;
if (false)
   do that;

However, here's a link that I used long back to help me with some RegEx :

I know I'm arguing against premature optimization in another thread at
the moment, but using regexps for this is overkill from the get-go:

if ($line[0] === '$' && substr($line, -3) === "%\r\n") {

This is both faster and easier to read. Regexps are great for more
complex stuff but something this simple doesn't demand their power (or
overhead).

Just a quick note on that, Rene

> $result = array (   "matches" =>

If you want to have the dollar sign included, use single quotes.
Double-quoted things translate the data enclosed within them, so
"$sometext" would translate that into the value of the variable (or
null with E_NOTICE if it's uninstantiated/undefined).  Conversely,
'$sometext' would be the literal $sometext.

What you tried only requires ONE a-z character somewhere in the input.

Try this:

preg_match('^[a-z]+$', $fname);

This will:
^ "anchor" the string at the beginning
[a-z]+ a to z, with at least one letter
$ "anchor" the string at the end

Note, however, that some people have other characters in their first
name, such as apostrophe, space, and dash.

Oh, and the digit 3, for "bo3b" who was a programmer on the first
Apple Macintosh.  His parents were hippies, and that really is his

You may want to obtain a LARGE list of "first names" and run them

What you tried only requires ONE a-z character somewhere in the input.

Try this:

preg_match('^[a-z]+$', $fname);

This will:
^ "anchor" the string at the beginning
[a-z]+ a to z, with at least one letter
$ "anchor" the string at the end

Note, however, that some people have other characters in their first
name, such as apostrophe, space, and dash.

Oh, and the digit 3, for "bo3b" who was a programmer on the first
Apple Macintosh.  His parents were hippies, and that really is his
name...

There was no escaping in the original either.

Also, I did assume that the list of replacements would grow to become
pretty large.  I wouldn't suggest doing this for a small list such as
that given in the example.

Given that you expect it to grow then you should have accounted for
special characters becoming part of the list. Additionally, you probably
think this technique is more efficient since you think that the regex
scans the list faster, it does not. If there is nothing to replace the
str_replace() call will be faster than the preg_match_all() call since
it isn't burdened with the overhead of regex special characters and
matching. Additionally, in the event of something actually needing
replaced, you will incur a second scan of the target string since
preg_match_all() doesn't perform the replacement as soon as it realizes
a match is necessary while still having the index of the replacement
spot available. In the event that nothing is replaced you can be assured
that str_replace() returns a virtual copy of the target string, in which
case no duplication overhead is incurred, only the effort to create a
COW version of the variable. This is about as fast as the creation of
the return value of preg_match_all().

Cheers,
Rob.

Don't do this, it's terribly inefficient and superfluously complicated.
There's no escaping of the strings either before jamming them into the
pattern. What happens if you need to replace ''.

Re: [PHP] Regular Expressions

This is a first attempt but the general idea is that the regular
expression matching is done in one operation and then str_replace() is
called only as many times as required instead of once for every line in
your list.  Also, str_replace() is faster than ereg_replace().

 "n",
"á" => "a",
"é" => "e",
"í" => "i",
"ó" => "o",
"ú" => "u"
);

$link = "ssrsrsrsóererrereísddósdssú";

if (preg_match_all("/(".join("|", array_keys($replace)).")/", $link,
$matches)) {
$matches = array_unique($matches);

foreach ($matches[0] as $match) {
$link = str_replace($match, $replace[$match], $link);
}
}

echo $link;

Use str_replace instead of ereg_replace. You don't need regular expressions
there.
Your code is good as it is, one line per string replacemente. Don't mess up
code readability just for the sake of some lousy optimization, it's not
worthy.



(in spanish)

Usa str_replace en lugar de ereg_replace. No necesitas expresiones regulares
en este caso.
Tu código está bien así, una línea por reemplazo. No arruines la legibilidad
del código solo por una optimización inútil, no vale la pena.

True, but you'll have to change the rexex not to match, 'ń' or

this function sucks - it does nothing more than wrap preg_match and
returns strings instead of boolean values.

regexp's become hard very quickly - but for simple checks like your
doing your probably better off using the functions in the ctype
extension:

how exactly do you define these regexps? seems like your forgetting to add a 
start/end delimiting
character to the regexp strings (as others have pointed out).

is this all your function will ever do, or do you plan on extending it

i made a list of rules that are passed into the function above

not sure how you are setting these up, but try something like this

$slpnum   = '!^[a-zA-Z0-9]+$!';
$slpha= '!^[a-zA-Z]+$!';
$number   = '!^[0-9]{2}$!';

the patterns seem ok, but you should enclose them within some delimiter
characters, e.g. "/[a-zA-Z][0-9]/" or something like that

Yes, but make sure you don't end up with a / inside your expression,
as that would mean the end of the expression.

You could also use another delimiter in your preg functions, i prefer
using the % symbol, but you could of course use anything you want :)

On 20/11/06, Paul Novitski <[EMAIL PROTECTED]> wrote:


Børge,

Here's how I would think this one through:

First, I'm having to make several guesses at the nature of your text content:

- You use the single word "topic" but I'll assume
this can be multiple words and spaces.

- Your source string includes a space after "rest
of the text " while your marked-up result
doesn't.  However I will assume that you really
do mean the rest of the text until end-of-string.

- Your source string also includes a space before
the initial  but your regexp pattern
doesn't.  I'll assume that both beginning and ending spaces are unintentional.


Your source string:

 " FF topic  99 rest of the text"

consists of these parts:

1) [start-of-string]
2) " "
3) "FF" (color code 1)
4) " "
5) "topic"  (text 1)
6) "  "
7) "99" (color code 2)
8) " "
9) "rest of the text"   (text 2)
10) [end-of-string]

i.e.:

1) [start-of-string]
2)  + whitespace
3) color code 1
4) whitespace
5) one or more characters
6) whitespace +  + whitespace
7) color code 2
8) whitespace
9) one or more characters
10) [end-of-string]

This suggests the regexp pattern:

1) ^
2) \s
3) ([0-9A-F]{6})
4) \s
5) (.+)
6) \s\s
7) ([0-9A-F]{6})
8) \s
9) (.+)
10) $

/^\s([0-9A-F]{6})\s(.+)\s\s([0-9A-F]{6})\s(.+)$/i

Everything in the source string that you need to
retain needs to be in parentheses so regexp can grab it.

In 5) I can let the pattern be greedy, safe in
the knowledge that there WILL be a /s to terminate the character-grab.

I end with the pattern modifier /i so it will
work with lowercase letters in the RGB color codes.

PHP:

$sText = ' FF topic  99 rest of the text';
$sPattern = '/^\s([0-9A-F]{6})\s(.+)\s\s([0-9A-F]{6})\s(.+)$/i';
preg_match($sPattern, $sText, $aMatches);
print_r($aMatches);

result:

Array
(
 [0] =>  FF topic  99 rest of the text
 [1] => FF
 [2] => topic
 [3] => 99
 [4] => rest of the text
)

This isolates the four substrings you want in regexp references $1 through $4.

Replacement:

[Tangentially, I'd like to comment that font tags
are passe.  I urge you to use spans with styling
instead.  I normally dislike using inline styles
(style details mixed with the HTML), but in this
case (as far as I know) you don't have any
choice.  If you can, I suggest you replace the
literal color codes with style names and define
the precise colors in your stylesheet, not your database.

[What this further suggests is that you ought to
have two discrete database fields, `topic` and
`description`, if you can, rather than combining
them into one field that needs to be
parsed.  Then you can output something like:

 TOPIC DESCRIPTION

and leave the RGB color codes out of this layer
of your application altogether.]


However, working with the data you've been dealt:

$sTagBegin = '';
$sCloseTag = '';

$sReplacement = $sTagBegin . '$1' . $sTagEnd . '$2' . $sCloseTag .
 $sTagBegin . '$3' . $sTagEnd . '$4' . $sCloseTag;

echo preg_replace($sPattern, $sReplacement, $sText);

result:

topic rest of the text



It's tempting to write the pattern more
succinctly to take advantage of the repeating pattern of the source text:

  COLORCODE text

The regexp pattern might be:

1) \s*
2) \s
3) ([0-9A-F]{6})
4) \s
5) ([^<]+)

1) optional whitespace
2)  + whitespace
3) color code
4) whitespace
5) one or more characters until the next <

$sText = ' FF topic  99 rest of the text';

$sPattern = '/\s*\s([0-9A-F]{6})\s([^<]+)/i';

preg_match_all($sPattern, $sText, $aMatches);

result:

Array
(
 [0] => Array
 (
 [0] =>  FF topic
 [1] =>  99 rest of the text
 )

 [1] => Array
 (
 [0] => FF
 [1] => 99
 )

 [2] => Array
 (
 [0] => topic
 [1] => rest of the text
 )

)

In this case, we need to specify the tag pattern only once:

$sReplacement = $sTagBegin . '$1' . $sTagEnd . '$2' . $sCloseTag;

echo preg_replace($sPattern, $sReplacement, $sText);

result:

topic  rest of the text

Notice is that this results in whitespace after
the topic string.  Someone more knowledgeable in
regular expressions can probably tell you how to
eliminate that, perhaps by using a regexp assertion:

Is there a way to make a regular expression to match on a particular way
the letters are arranged?  For instance, if you had a word:

THAT


It could match on any word in the dictionary that had the form:

1231

preg_,match('/^(\w){1}\w\w\1$/');

would match the above on a single line for example, where \1 refers to the
pattern captured in parentheses at the start.

Try and be a little more specific in what you want to match, as regex is
hard enough to start with - a detailed and clear description will elicit
corresponding responses.

I believe I stubbed my toe on that fact once, yes...

I always manage to mess up the greedy/ungreedy stuff, and then throw
up my hands and try to use an expression to look for a specific
character to be there or not there, and then I don't have to worry
about the greedy stuff as much...

Sometimes, though, you have to grit your teeth and dink with ? and U
until it works.

I kind of talked about this in the reply to richard the .*? is exactly

an inline modifier to the previous expression.

That makes me wonder.. according to the docs U inverts greediness, if

You're right; I'm wrong.

I'm not PCRE expert.

Took me 20 years to be able to stumble through the simplest expressions.

? means "maybe" in some other place in PCRE.  Or maybe that's POSIX.
Never have figured that one out.


The ? after * means ungreedy only.. so your basic:
 a? means a or no a in the regular usage

The easiest to remember is that ? two basic definitions:
 - extend the meaning of
 - 0 or 1 of the previous expression



/foo(?i)bar/

matches FOoBar, fOObar, foobar.. the (?i) extends the meaning of
(?[modifer-list])  to contain modifiers of the previous expression and
no more

/foo.*?bar/
 is the same thing as saying /foo.*(?U)bar; a short cut, much like
what \d is a shortcut to [0-9]

/foo(?<)/
 a look behind assertion

/foo(?=...)/
 a look ahead assertion

(and a negative of the  assertions are allowed)

/foo(?(condition)yes:no)/
 condition usually being an assoertion of some sort


I still dont understand it, and it is one of the reasons why people
have problems using regex, it really is a whole different language,
using Regex Coach as chrome did, is the probably the best way to find
out the problem or how to match what you are looking for...

A nice little overview (although i have read it about a few dozen
times and still cant apply the logic 100% of the time)
php.net/reference.pcre.pattern.syntax.php

on the other hand, people still want html parsers written in PCRE.. :)

Download "The Regex Coach" and play with that -- It's not 100% the

ms because newlines inside the text are okay

The regex you wrote lacks separator. That PHP statement will occur an
error:

> Warning: preg_match() [function.preg-match]: Unknown modifier ']' in
> /path/file.php on line X

The statement should be:

preg_match("/]*>(.*?)<\/h1>/i", "Welcome to my homepage",
$matches, PREG_OFFSET_CAPTURE);
print_r($matches);

Try this, and read up on regular expressions - it's an essential
knowledge if you're a programmer.

$text = "this is where the contents of your search result page goes";
preg_match_all('|]*href="([^"]+)"[^>]*>([^<]+)<\/a>|U', $text,
$links, PREG_SET_ORDER);
print_r($links);

RE: [PHP] regular expressions and Phone validation

[Jay Blanchard]

[snip]
I have one small problem I don't understand the preg_replace() method.
 I understand the gist of what it does but I still don't fully know
what it does.  I have read the entry in the php manual about this and
I am still confused about it. I've never been any good with regular
expressions.

Here is the function in use:

function checkPhone ($Phone)
{
global $errmsg;
if (!empty($Phone))
{
$Phone = ereg_replace("[^0-9]", '', $Phone);

if ((strlen($Phone)) <= 14)
return
preg_replace("/[^0-9]*([0-9]{3})[^0-9]*([0-9]{3})[^0-9]*([0-9]{4}).*/",
"(\\1) \\2-\\3",$Phone);
}
}

I think my problem is mostly what is returned when preg_replace
executes?
[/snip]

There are several methods of doing phone number validation, one was even
mentioned last week. You may try the archives for answers.

What are you trying to do here? Once we know that we can probably help
you.

Also, you could try the O'Reilly book - Mastering Regular Expressions.
It's hardly bedside reading, but very thorougher.

It isn't PHP specific, but it is a very good guide from the ground up. It
isn't very good for 'quick reference' cookbook type stuff, but it will
give you a very good understanding of regex.

If you run Linux as a OS, there are a couple of regex gui's
(KregExpEditor for KDE) which are helpful. You 'design' the expression in
the interface and it gives you the actual reular exp as the result. I
am finding this a good way of learning, i.e. figuring out how the result
came about...

Just my thoughts...

Depends on what regexp function you use, what exactly you want to match,
and whether or not you want to know, after you match, any of the
segments. Rasmus has given you one possible pattern that works with the
ereg functions. If you wanted to use a preg function and wanted to match
3 digits, a space, two m', one or more spaces, and 3 digits, you would
use:

preg_match('/^\d{3} mm\s+\d{3}$/', $string);

But, what it all comes down to is: you need to determine what PATTERN
you need to be able to match. Once you know that, you can write the
regexp.

ok for this 2:

but have these next instructions the same result?

You would be far better off using the built-in mysql_escape_string (recent
PHP versions) or http://php.net/addslashes

You might want to try to use Regex as an exercise, but this ain't the
place for it on a real site.

No need for a regex.  Use something like mysql_escape_string() or 
addslashes().  That's what these functions are made for.

The Camel book is a good place to start your regex learning.

If you don't plan on doing anything this weekend, pick yourself up a 
copy of O'Reilly's Regular Expressions.  It's "The Owl Book", by the cover.

The reason why I ask if you have all weekend is because it's a good 
book, but at 300+ pages, it's a good read.  I still don't know my 
regex's very well, but then again, I just kinda skipped through it. 
However, it is laid out in a format that makes it a very good reference 
book, so if you're looking to do something, then this book makes it easy 
to "piece things together" and find a regex that works quite well.

If so, do htmlentities() to the data being displayed. That will turn the

I would keep magic quotes off and do the escaping myself. This way you
know exactly what is happening.

What you need to do is addslashes() to the data before putting it in the
sql query.

/^(1?[1-9]|[12]0)$/ works too.  The first part covers 1-9, 11-19; the 
second part gets you 10 and 20.

Plus, it's ever so slightly shorter!  And isnt' that what's most 
important? :P

You are missing a [ before the 1-9 in after the last |

The regex WILL work if you type it correctly :-)

Whoops. Sorry.. That's what I get for throwing out an answer while on

Try this:

";
  else
echo "It's not!" . $i . "";
}

?>

The for loop is just for show.

You're far better off doing it arithmetically as someone already said,
however  if you absolutely *have* to use a regexp then this is how you
go about it:

You need to match these possible variations:
1. the number '20'
2. the number '1' followed by any digit between 0 and 9.
3. any digit between 1 and 9.

the pattern for the first one is easy. it's just a fixed string: 20
the pattern for the second is only slightly harder: 1[0-9]
the pattern for the third is: [1-9]

You want to match any of them, so you join them together with an
alternation operator, the '|' symbol to get: 20|1[0-9]|[1-9]

This will match any string that contains the numbers 1-20, such as
'200'. To make sure it only matches exactly the numbers you're
interested in, you have to "anchor" the start and finish ending up
with this:

if (preg_match('/^(20|1[0-9]|1-9])$/', $candidate)) {
   // $candidate is a decimal integer between 1 and 20 inclusive with
no leading zeros.
}

If you *need* to do it with regexp, try this:



if (preg_match("/[2-19]/",$x))
  echo "It is!";





If 1 and 20 are values you want to verify too, change 2-19 to 1-20.

  preg_match('|^Last Name:(.*)$|m', $haystack, $matches);

Thanks for the quick help.

Both ways,
preg_match('/Last Name:\s*(.*)\n/', $inputStr, $regs);
and
ereg("Last Name:\s*(.*[^\n])", $strInput, $regs);
work fine.

However if I have,
Last Name:
Street: Teststreet
(no entry after last name)

Both search strings return me:
- 

Street: Teststreet
- 

Also why doesn't "Last Name:\s*(.*)$" work, and neither "^Last
Name:\s*(.*)". Both strings are not found at all - that's why I thought
the php implementation might treat new lines in a strange way.

Can anybody explain these effects to me?

Donno about regular expressions but with perl compatible you can use:
preg_match('/Last Name:\s*(.*)\n/', $inputStr, $regs);

PHP's PCRE (Perl Compatible Regular Expressions).

http://php.net/pcre

Some of the documentation there can get a little bit like reading a
complex regular expression.  A good book might help:

Re: [PHP] regular expressions php/perl/actionscript

[Gabino Travassos]

Thanks for the suggestions. Between the online manual and the books I have I
think I'll get there eventually. Sometimes my logic just sux. What I needed
to do was have the user fill out a form and if they make changes to the XML
file I would update the file. So, my long way around was to go through the
old XML file and create a string variable for every possible form field.
Then I would compare the /bgClrOld/ to /bgClr/ and if they were different I
would then update the file with an ereg_replace.

After some poking around, this seems to be the way to go. Only if the field
is not empty so I change it

if ($bgClr !=""){
$bgClr="xx";
}

I still have some work to do, but ...
