[PHP] Regular Expression to get the whole Comma Separated String in Array Key
Hi All,
Need help in resolving the below problem-
I would like to get the whole comma separated string into an array value-
1. $postText = chapters 5, 6, 7, 8;
OR
2. $postText = chapters 5, 6;
OR
3. $postText = chapters 5, 6, 7;
What i have done so far is-
preg_match('/chapter[s]*[ ]*(\d+, \d+, \d+)/i', $postText, $matches);
The above will exactly match the third value $postText = chapters 5, 6, 7;
By Above $matches will contain a value of : $matches[1] = '5, 6, 7';
Now i need a SINGLE regular expression which can match first, second
variable above or any number of comma separated string and IMPORTANTLY
provide me that whole comma separated sting value (as above) in single array
key element like below-
$matches[1] = '5, 6, 7';
OR
$matches[1] = '5, 6';
OR
$matches[1] = '5, 6, 7, 8, 9';
Also I have to use regular expression only as the flow of the code does not
permit to use any other method to get comma separated string from the
master/base string.
Thanks,
Gaurav Kumar

Tanel
Use preg_match() to find an expression within a string. You can use
something like this to grab check if a string contains only letters or
numbers:
if(preg_match('/^[a-zA-Z0-9]+$/'), $string)
{
}

-0.12354765900E+03 0.46259109000E+02
What I am trying to do here is to only have
1 -0.123701962557954E+03 0.460967618024691E+02 be the output so I
can do further processing with it, however, with the code I have in the
following, I have both lines in the output. Here is the code:
$file = test.txt;
$fp = fopen($file, r);
$lines = file($file);
foreach($lines as $line_num = $line)
{
if (preg_match(/([^0-9]+\s+)(\-?\d+\.?\d+(\+?E?\d+)?){2}/, $line))
echo $line;
}
Could anyone please tell me that even when I specify that the line has to start
with [^0-9]+\s with one occurrence, why I still get -0.12354765900E+03
0.46259109000E+02?

Hi,
I have two lines here as follows:

-0.12354765900E+03 0.46259109000E+02
What I am trying to do here is to only have
1 -0.123701962557954E+03 0.460967618024691E+02 be the output so I
can do further processing with it, however, with the code I have in the
following, I have both lines in the output. Here is the code:
$file = test.txt;
$fp = fopen($file, r);
$lines = file($file);
foreach($lines as $line_num = $line)
{
if (preg_match(/([^0-9]+\s+)(\-?\d+\.?\d+(\+?E?\d+)?){2}/, $line))
echo $line;
}
Could anyone please tell me that even when I specify that the line has to
start with [^0-9]+\s with one occurrence, why I still get
-0.12354765900E+03 0.46259109000E+02?
Thanks a lot for your help.

what about a regex something like:
/^(\d{1,})\s+([\d\.E\+\-])+\s+([\d\.E\+\-])+$/
The brackets () allow you to then extract the specific portions of the
string as you wish, so the first match is the whole line, the second is
the 1 (or whatever other number), the third is the first floating-point
number, etc.
I'm assuming that the 1 here is some sort of line number possibly? The
bit inside the curly braces ({1,}) just says to match the digit 1 or
more times. You can limit it by adding a number after the comma, so
{1,3} for 1-3 digits.
Hope this helps?

[PHP] Regular Expression differences between 4.4 and 5.2
Hi everybody, I'm trying to migrate our PHP code base to PHP5. For the most part the transition hs been smooth however I'm really stuck on a regular expression which gives different results in 4.4 and 5.2. I've looked through migration guides but as far as I can see nothing should have changed in Regex handling between the versions. I've created the following script below to test the match: ?php include( 'input.inc' ); $pattern = /!T_([^ ]+)([^]*)(.*?)!T_end\\1|!T_([^ ]+)([^]*)/si; preg_match_all( $pattern, $string, $matches ); echo phpversion(); var_dump($matches); ? Input.inc contains the string that is giving the different results - its probably to long to include so you can find it at http://www.workingweb.nl/example/input.inc. The results of this being run can be seen at: PHP4 (desired result) - http://www.workingweb.nl/example/php4results PHP5 - http://www.workingweb.nl/example/php5results If the pattern modifier 's' is removed the regex behaves consistently again (but this breaks other pages on our website so can't be used as a workaround). Besides I don't see why that should make any difference. Here is the version information from the PHP CLI versions I've been testing with: [EMAIL PROTECTED]:~$ php4 -v PHP 4.4.4-8+etch6 (cli) (built: May 16 2008 15:59:34) Copyright (c) 1997-2006 The PHP Group Zend Engine v1.3.0, Copyright (c) 1998-2004 Zend Technologies [EMAIL PROTECTED]:~$ php5 -v PHP 5.2.0-8+etch11 (cli) (built: May 10 2008 10:46:24) Copyright (c) 1997-2006 The PHP Group Zend Engine v2.2.0, Copyright (c) 1998-2006 Zend Technologies Any help on this would be very appreciated.

Hi Jochem, Replacing the 's' modifier with 'm' fixed it this instance but broke other parts on the site (the same result as removing 's').

Re: [PHP] regular expression question
But how? The +[a-z]{2,} seems to allow at least two a-z clusters, but it
doesn't include a period. /ml
Almost correct. The plus belongs to whatever comes before it, not after.
So what you're referring to as matching two or more characters but not
the period, is this:
[a-z]{2,}
And this will match one or more subdomains:
([-a-z0-9]+\.)+

[PHP] regular expression question
Hello:
I've adapted this regular expression script from a book, but I'm not
clear why it works.
$email = [EMAIL PROTECTED];
$pattern = /[EMAIL PROTECTED]@([-a-z0-9]+\.)+[a-z]{2,}/;
___
if ( preg_match($pattern,$email) )
{
print yes! . $email . matches!;
}
else { print no match; }
___
When I run this script, I get the yes! [EMAIL PROTECTED]
matches! statement.
But I don't understand why the second half of the regular expression
works. I'm talking about this part:
@([-a-z0-9]+\.)+[a-z]{2,}/;
why is it able to detect repeated sections of the email address after
@ that are separated by periods? like @email.alaska.com . It
looks to me like it's only looking for one example of that pattern.
Does the () allow an unlimited number of patterns to pass?
thanks for any and all guidance

That plus applies to the grouping () before it:

RE: [PHP] Regular expression - URL validator
Thanks again Jim,
That's what i really need.
I'm testing this function...
If i put a URL like www.example.com, then it works fine and turns it to
http://www.example.com
But if i put a URL like http://www.example.com, then it also put another
header so it turns to http://http://www.example.com
I also tried with the strstr function, but receive the same response.
Thanks in advance,
Wagner.

You could always do a string comparison for http(s)? in the url
if ( strpos($url, array('https://', 'http://')) === false ) {
$url = 'http://'.$url;
}

Yes, make sure you have http:// on the front.
?php
if (strtolower(substr($link, 0, 7)) != 'http://') $link =
http://$link;;

you must use http://www.aol.com not www.aol.com. coz the later is not a
valid url. The protocol is not specified there. and if you use
www.aol.comis your href of a tags, the browser will automatically add
your current web
address as prefix as if its a relative url.
if your site is http://www.example.com/folder/site.html
and if you use href=/www.aol.com it will show http://www.example.com/
www.aol.com
if you use href=www.aol.com it will show
http://www.example.com/folder/http://www.aol.com/
www.aol.com
you have to use href=http://www.aol.com; the absolute one.

[PHP] Regular Expression just one step away from what I need....
Given the string 'foo''bar''glorp' (all quotes are single quotes)I had hoped to find a regular expression using preg_match that would return an array containing just those words without having to go through additional gyrations, like exploding a string to get an array. I have only had limited luck $theString = 'foo''bar''glorp'; preg_match( /\'(.*)\'/, $theString, $matches); print_r($matches); Array ( [0] = 'foo''bar''glorp' [1] = foo''bar''glorp ) Of course $matches[0] has the entire string and $matches[1] contains the returned string minus the leading and trailing single quote. I can explode $matches[1] to get what I want, but it is an extra step and I am sure that I have done this before but cannot locate the code in question. I would like the results to be Array ( [0] = 'foo''bar''glorp' [1] = foo [2] = bar [3] = glorp ) That way I can use the $matches array without having to create another array to hold the values. I feel as if I am really close on the regex to do this, but cannot seem to find (after much head scratching and teeth gnashing) the proper solution.

it works, but it's too permissive, it replaces too much links (some
links with some get parameters must stay unchanged)
I don't really understand my pattern...it's a little strange for me...lol
I wouldn't like to rewrite links that contains any of the following

noLoader
noLeftCol

[PHP] Regular Expression Problem
Hi List
I must be dumb as I have been battling my way through regular expression
examples for a while and I can not work out why the following does not work
properly. I am the first to admit that regular expressions confuse me greatly.
The string is a piece of XML as follows and I have put that string into a
variable called $xml_string
flights
flight flightId=19417361 addAdtPrice=0.0 addChdPrice=0.0
addInfPrice=0.0
legXRefs
legXRef legId=23862812 class=V/legXRef
legXRef legId=23862813 class=V/legXRef
/legXRefs
/flight
flight flightId=19417360 addAdtPrice=0.0 addChdPrice=0.0
addInfPrice=0.0
legXRefs
legXRef legId=23862810 class=V/legXRef
legXRef legId=23862811 class=V/legXRef
/legXRefs
/flight
/flights
What I am trying to do is extract the first flight . /flight chunk.
I am using the following, based on the example at
http://php.net/manual/en/function.preg-match.php example 3
preg_match('#flight .*\/flight#', $xml_string,$matches);
$tempstr = $matches[0];
What I actually get in $tempstr is everything from the first flight through to
the last (second) /flight
I would have expected preg_match to have matched from the first flight through
to the first /flight.
I suspect I do not have the regular expression correct. I would great appreciate
any help on sorting out the regular expression so that it only returns the first
chunk of the string.
Regards,
Richard Luckhurst

Hi Roman, RN Are you doing this to learn regular expressions or are you actually RN trying to do work? Because you're going the wrong way. RN It's XML, why do you treat it as text? I am well aware it is XML and I could use an XML parser or simpleXML. I am trying to learn regular expressions as I have a fair bit of work coming up that will require the use pattern matching within strings. It just so happens that some of the data looks like XML, hence the reason I am using a piece of XML for this learning process.

Strange, you should have gotten nothing:
s (PCRE_DOTALL)
If this modifier is set, a dot metacharacter in the pattern matches
all characters, including newlines. Without it, newlines are
excluded.
I would have expected preg_match to have matched from the first flight
through
to the first /flight.
As Jochem wrote, you also need U (PCRE_UNGREEDY).

You can also ask regexp to return the text up to but not including

'flight ' followed by one or more characters that aren't ''.

You want to add a 'U' after you closing # so that matches are
Ungreedy -- I.e., they do NOT grab as much text as the can to
fulfill the pattern (greedy) but they grab as LITTLE text as they can
to fulfill the pattern (ungreedy)

Hello Roman,

it's a hint as to how you might use simpleXML to extract the values of a src
attribute from the definition of an img tag.
I forgot to mention that this part:
img width=99 height=120 border=0 src=%s /',
is not always the same. The image properties can vary.
Thanks

I need to strip all characters from the following text string exept the
image path...
img width=\99\ height=\120\ border=\0\
src=\../../images/new/thumps/4123141112007590373240.jpg\ /...and then
store the path to DB. Image path lengh can vary so I guess that I need to
extract all characters after scr=\until next\or
somethig
similar.
This passes with 5.2:
class ImgSrcTest extends Tence_TestCase
{
private $src, $str, $xml;
function setUp()
{
$this-src = 'fubar.jpg';
$this-str = sprintf(
'img width=99 height=120 border=0 src=%s /',
$this-src
);
$this-xml = new SimpleXmlElement($this-str);
}
function testReturnsAttributeAsSimpleXMLElements()
{
return $this-assertEquals('SimpleXMLElement',
get_class($this-xml['src']));
}
function testCastToStringYieldsTheAttributeValue()
{
return $this-assertEquals($this-src, strval($this-xml['src']));
}
}

It's a unit test showing how you can use SimpleXML to do what you want.
It's written for Testilence out of sheer laziness, but any unit testing
tool would do (after cosmetic changes to the code).
The test case contains two pretty obvious tests, just read the
function names, their bodies should be pretty obvious. On thing that
might be a little non-obvious is the strval(): that was the only way I
found to get the string out of the very uncommunicative
SimpleXMLElement.
I forgot to mention that this part:
img width=99 height=120 border=0 src=%s /',
is not always the same. The image properties can vary.
That's one of the reasons I didn't go the regexp route.
Don't treat XML as text, it's not.

Re: [PHP] Regular Expression help
Those patterns aren't anchored to the ends of the string, so as long as the string contains one matching character, the succeeds. ^ anchors the pattern to the beginning, \z to the end, so you want: /^[A-Za-z]+\z/ Or test the opposite case to see if it fails: /[^A-Za-z]/ Arpad Chris Boget wrote: ?php echo 'Is String: [' .

Note that $ allows a trailing newline, but \z doesn't. Arpad Stut wrote: Chris Boget wrote: ?php echo 'Is String: [' . ( is_string( 'a1b2c3' ) preg_match( '/[A-Za-z]+/', 'a1b2c3' )) .
