Correction:
preg_match_all('/\{\{lang:(.*?)\}\}/', $str, $tags);

FWIW, you can tell just the .* to be un-greedy using a ? like so:
preg_match_all('/\{\{lang:(.*?)\|\|/', $str, $tags);

[PHP] preg_match_all question
Hi All,
Having an issue with regular expressions, never been my strong point!
The following pattern only picks up one instance per line, if more than
one instance exists all text from first {{ to last }} is included, can
anyone point out where I am going wrong?
preg_match_all("/\{\{lang:(.*)\}\}/", $str, $tags);
Here is an example of what needs to be processed
{{lang:PA1Feature1}}{{lang:PA1Feature2}}
{{lang:PA2Feature1}}{{lang:PA2Feature2}}
TIA

Re: [PHP] preg_match_all nested html text
Do you just wish to remove all the HTML tags from a given string? If so,
the strip_tags() function should do this.
Ash
www.ashleysheridan.co.uk
--- Begin Message ---
I am trying to get the text between nested html tags within arrays
produced by preg_match_all. The simple situation would be:
test
I want to return 'test'.
Assuming $post_results has some string derived from a html page source
with lots of nested tags.
Replacing new line (seems to be a good idea to do this):
$post_results = ereg_replace("[\n\r]", " ", $post_results);
I tried this:
$pattern = "/<[^>]*>(.+)<\/[^>]*>/i";
Explanation (as far as I understand, please feel free to correct):
/.../ start end
< - opening html tag
[^>] end tag
* any number of same
end tag - don't understand why needed in addition to above
(.+) group: any number of any characters
< opening tag
\/ literal forward slash
[^>] end with tag end
* any number of same
end tag - don't know why needed again
i - modifier, can't remember what it means, something like case
insensitive, yes, that would be it
//Main expression for first try, substituting tags:
preg_match_all($pattern,$post_results,$outputs);
//this only replaces the outer tag eg , not the , so:
while(stristr($outputs[0][1],"<")) {
preg_match_all($pattern,$outputs[0][1],$outputs,PREG_PATTERN_ORDER);
}
Is there a neat expression to get the inner text withing nested html tags?
Thanks,
John

Sorry there was an error in that. It felt wrong when I sent it so I
looked again. Here is a snippet I'm using on a project right now, so
I know it works. ;)
$dom = DOMDocument::loadHTML($vo->htmlCopy);
foreach ($dom->getElementsByTagName('a') as $node) {
if ($node->hasAttribute('href')) {
$linkVO = new ...;
$linkVO->url= $node->getAttribute('href');

Hi...
I have a little function to explode URLs with the following pattern:
$str = filename;
$pattern = '=^.*]*>(.*).*$=ims';
while (preg_match($pattern, $line, $exploded_url)) {
some usefull stuff
returns an array ($exploded_url)
}
$exploded_url[1] = protocoll;
$exploded_url[2] = URL;
$exploded_url[3] = name of the URL;
greetings
MG

Actually it returned both, just not how I had thought first. I forgot to

nonetheless :)

Your preg isn't going to return the URLs (even if it works), it's going
to return the labels of the links. But anyways...

[PHP] preg_match_all
What I want to do is find all links in an html file. I have the pattern
below. It works as long as there is only one link on a line and as long
as the whole link is one line. It seems there should be a way to get
this to work with more than one link on a single line. The work around
I have done for now is to read the whole file into a buffer and remove
all new lines and then add a new line after every closing a tag. Then
process each line. There has to be a better way.
Any Ideas? Also note I don't want to find any a tags that don't have an
href there probably aren't any but just in case.

Re: [PHP] preg_match_all Help
Assuming you know all the permissible div tag classes you want to capture the
contents of
I'd make an array list of them and the use a foreach() loop and capture the
contents you want and not try to capture the contents between the channel divs.
Assemble the output array inside the loop. You can also easily keep track of
which channel ID the contents came from.
What you are attempting directly with preg_match_all() is possible; but, the
required pattern is very messy and will be hard to test to make certain it's
perfect.

Off the top of my head. This wouldn't allow for using the right angle

You could set a class attribute for the image in
html and scale it in css. An img {width: 100%;}
would hold the size to the maximum of the parent.

Scaling the image in the browser is horrible for performance on the
client side...
The entire image still gets downloaded, and then the poor browser has
to scale this monster image down.
You may want to re-think your plan of attack...
You could, for example, force users to only use "registered" images,
and if they "register" an image large than 500, use http://php.net/gd
to scale it down.
As far as matching the image tag correctly goes, I'd have to suggest
that you try using a DOM to parse the HTML instead of regex.
That said, to get the WHOLE img tag in the same vein as you are using
now:
preg_match_all("/\< *[img][^\>]*[src] *= *[\"\']{0,1}([^\"\'\ >]*>)/i",
Note the addition of a closing ">" which will mark the end of the img
tag.
The [img] and [src] are kind of wonky, really, as they would also
match this bit of nonsense:
Sometimes italics could have bogus attributes.
YMMV

Re: [PHP] preg_match_all to match tags
Guys i would like to thank you for the help.
Jan i used some of your code to help me get this. There was one issue
with yours, preg_match_all while in a foreach will only match the last
match and output that as the $m array.
Here is the code, i hope someone else can use it. Its a working code
in PHP4 and PHP5. I am currenly wrapping the imageManip(); around the
$_POST variable that is the blog post when im posting it to the SQL.
So the getimagesize(); only has to run once.
There is one bug, if the user resizes the image manually to something
less than 590, to say maybe 400, this program will still resize it to
590.
function imageProportions($image)
{
$imageLoad = @getimagesize($image);
// if the image is larger than 590 pixels, it will resize both
height and width
// if not it will do nothing to the variables.
if($imageLoad[0] > 590)
{
$proportion = $imageLoad[0] / $imageLoad[1];
$imageLoad[0] = 590;
$imageLoad[1] = $imageLoad[0] / $proportion;
return array($imageLoad[0], ceil($imageLoad[1]));
}
else
{
return array($imageLoad[0], $imageLoad[1]);
}
}
function imageManip($data)
{
// match all image tags (thanks to Jan Reiter)
@preg_match_all("/\< *[img][^\>]*[.]*\>/i", $data, $matches);
if( is_array($matches[0]) )
{
// put all those image tags in one string, since preg match all
needs the data
// to be in a string format
foreach($matches[0] as $match)
{
$imageMatch .= $match;
}
// match all source links within the original preg match all output
@preg_match_all("/src=\"(.+?)\"/i", $imageMatch, $m);
// for each match that has the same key as the second match,
replace the entire
// tag with my tag that includes width, height and border="0"
foreach($matches[0] as $imageTagKey => $imageTag)
{
foreach($m[1] as $imageSrcKey => $imageSrc)
{
if($imageTagKey == $imageSrcKey)
{
$imageStats = imageProportions($imageSrc);
$data = str_replace($imageTag, "", $data);
}
}
}
}
return $data;
}

RE: [PHP] preg_match_all to match tags
Maybe this is what you are searching for:
$images = array();
$data = "blah src=blah.png ";
preg_match_all("/\< *[img][^\>]*[.]*\>/i", $data, $matches);
foreach($matches[0] as $match)
{
preg_match_all("/(src|height|width)*= *[\"\']{0,1}([^\"\'\ \>]*)/i",
$match, $m);
$images[] = array_combine($m[1],$m[2]);
}
print_r($image);
It will produce:
Array
(
[0] => Array
(
[src] => img.png
[width] => 400
[height] => 600
)
[1] => Array
(
[src] => gg.tiff
)
)
I wrote it just as an example. So you may modify it for your needs!
Does anyone know if there is a way to put this into ONE regex??

#your_content_div img { max-width: 500px !important; }
OK, so it won't work with IE6. Screw them.
But if the height is set in the img tag it'll keep that, so the image
could become distorted. So, you could also do something like:
#your_content_div img { visibility: none; }
Then run some Javascript routine onload to properly figure the
dimensions of each image. Adjust the width down to 500px, if necessary,
then the height by whatever percent difference between original width
over new width:
var new_height = (original_width / 500) * original_height;
Then, whether you change the dimensions of the image or not, change the
visibility of each to 'visible'.
So, um ... no PHP involved.

I see where things are being matched, but how are they being replaced? What you really
need here is preg_replace_callback(), probably.

Because you do not have an ending delimiter. In fact, you don't have a
starting delimiter, either, but preg assumes you meant the ^ character to be
your delimiter.
This is explained in all of the examples in the manual, but you must
surround your regular expression by a delimiter such as the / or #
character. This is because you can include modifiers after the delimiters to
further create your regex.
if(preg_match_all("/^([00])?.*$",$called,$found))
Although I doubt that'll work like you want it since [00] matches a zero, or
another zero. It only matches one character.

I wouldn't even use preg for this. Just use ltrim() or
if(substr($called,0,2)=='00')...

I basically have a phone bill that sometimes has the phone number

You need to enclose your regex in /regex/
if ( preg_match_all ( "/^([00])?.*$/", $called, $found ) )

preg_* functions needs delimiters for the expression like
'//' or if there are likely to be / in the text you can use
others like
'!!'
Its also a good idea to use single quotes so the expression gets
ignored by php

Re: [PHP] PHP preg_match_all()
It's in the manual:
/U/ (PCRE_UNGREEDY)
This modifier inverts the "greediness" of the quantifiers so that
they are not greedy by default, but become greedy if followed by
"?". It is not compatible with Perl. It can also be set by a (?U)
modifier setting within the pattern.

I am having to edit a php script that one of our previous employees had
written and I am having a problem understanding the preg_match_all function.
preg_match_all("||U", $read, $result2);
here is what I THINK I know: The | at the beginning signifies the start of
the text to search for, then the actual text to search
- the (.*) means to include everything after the / in the search as
wellwhat I dont quite understand is what the |U is actually
doingthen it tells the function what variable to $read and what new
variable to store in: $result2
can anyone fill me in if my logic is not correct and what exactly the |U is
doing in this function?

Here's an excerpt from 'perldoc perlre':
By default, a quantified subpattern is "greedy", that is, it will
match as many times as possible (given a particular starting location)
while still allowing the rest of the pattern to match. If you want it
to match the minimum number of times possible, follow the quantifier
with a "?". Note that the meanings don't change, just the
"greediness".
As John Holmes has already pointed out, you can add the U modifier,
but I would recommend that you learn to use the ? quantifier, since
this is more portable as Perl doesn't recognize the U modifier. So
you'd want to change this:
/begincommand(.*)endcommand/
to this:
/begincommand(.*?)endcommand/
If you have an install of Perl handy I also recommend taking a look at
'perldoc perlretut', I've found it very helpful.
HTH...

[PHP] preg_match_all()
As described in http://www.php.net/manual/en/function.preg-match-all.php, I
have put in place a bit of code theoretically designed to parse out snippets
of text embraced with an open and close tag. The code I am using is this:
preg_match_all('/begincommand(.*)endcommand/',$messagebody,$commandOuttake,P
REG_PATTERN_ORDER);
print $commandOuttake[0][0]." (0,0), ".$commandOuttake[0][1]." (0,1)\n";
print $commandOuttake[1][0]." (1,0), ".$commandOuttake[1][1]." (1,1)\n";
For this input
random words begincommand another test string 1[endcommand] a couple of
random words [begincommand]2nd instance of command in same email test string
[endcommand] and then a bunch of nonsense
this code produces this output:
begincommand another test string 1[endcommand] a\r\ncouple of random words
[begincommand]2nd instance of command in same email\r\ntest string
[endcommand (0,0), (0,1) another test string 1[endcommand] a\r\ncouple of
random words [begincommand]2nd instance of command in same email\r\ntest
string [ (1,0), (1,1)
In other words, the fact that I have the begincommand ... endcommand TWICE,
the preg_match_all only accepts the OUTER open and close tags. It never
stops at the first endcommand as I am trying to make it do. The string "
a\r\ncouple of random words" should never show up!
I've tried this with and without the PREG_PATTERN_ORDER, with ereg,
preg_match and various and sundry other variations, and I am at a loss. How
do I change the criteria to stop at the first instance of a match? How do I
parse out only up to the first instance of "endcommand"?
I am not certain if I am subscribed directly to this list, so in answering,

http://www.xxx.com"; class=M>xxx
the regular expression that i use is:
preg_match_all("/([^<]+)<\/a>/",$buffer,$ma
tch);
by this expression i get the same values more then one time. but i
absolutely know that there's no repetation of same value. probably my

Re: [PHP] preg_match_all - how does it work?
Hi Randall,
If you look closely at the definition of preg_match_all(), you'll see
that it generates an array of arrays--that's because, for each match, it
generates an array that corresponds to the result of a single call to
preg_match, then puts all the resulting array into another array.
If you use PREG_SET_ORDER, your $match array contains an array for each
of the matches found. Each array then contains:
* The entire matched string in element 0
* Each of the substring (defined in brackets in your pattern) starting
from array 1.
Hope this helps!

[PHP] preg_match_all - how does it work?
I have some experience in using regular expressions in Perl, and have been
able to use preg_match in php, but am having a problem with preg_match_all.
I'm trying to extract data from an HTML table. Here's my preg_match call
that correctly grabs the 1st row of data in the table. It grabs 4 columns of
data:
preg_match("|(.*?)<.+?(.*?)<.+?(.*?)<.*?[ ]*(.*?).*?|", $res, $match);
If I use preg_match_all on the same table:
preg_match_all("|(.*?)<.+?(.*?)<.+?(.*?)<.*?[ ]*(.*?).*?|", $res, $match, PREG_PATTERN_ORDER);
...and try to print output, I get:
$match[0] = Array
$match[0][0] = Array[0]
$match[1][0] = Array[0]
$match[0][1] = Array[0]
$match[1][1] = Array[0]
Same result with PREG_SETORDER.
What am I doing wrong?

I had this problem only a day ago. You have forgotten to add slashes to
your pattern. The variable $pattern looks something like this:
"\d+\s"
when it should look like this:
"/\d+\s/"
Hope that was helpful,
Archie

[PHP] preg_match_all problem
Hi, I'm a frog (french),
I,ve some troubles with the preg_match_all function.
$strSearchWords = Trim($search);
$pattern = $strSearchWords;
andwhile (!feof($openFile))
{
$strFileContents .= fgets($openFile, 4096);
}
$strPageTitle = htmlentities(GetFileMetaTag("",
"", $strFileContents));
$strPageDescription = htmlentities(GetFileMetaTag("", $strFileContents));
$strPageKeywords = htmlentities(GetFileMetaTag("", $strFileContents));
$strFileContents = $strPageTitle." ".$strPageDescription."
".$strPageKeywords;
$strFileContents = str_replace("; "," ",$strFileContents);
$strFileContents = str_replace(","," ",$strFileContents);
then I get the following warning message:
Delimiter must not be alphanumeric or backslash in :
if (preg_match_all($pattern,$strFileContents,$match) > 0)
WHAT CAN I DO ???

[PHP] preg_match_all href|src function
Hi All,
I have being working on PHP perl compaitable regular expressions for the last
month and cannot work out how to program a preg_match_all that will get the
"file.html" from the following examples:
The preg_match_all I have below only works for but not for
the other variations...
preg_match_all("|href=\"?([^\"' >]+)|i", $data, $links);
I tried the preg_match_all below, but that didn't work...
preg_match_all("|(href|src)=([^\"']+)?([^\"' >]+)|i", $data, $links);
Any help would be greatly appreciated.
Regards,
Michael.

[PHP] preg_match_all...grrrr!!!
I've never had good luck with this function. I first learned how to (sorta) use it from looking at other code. It worked fine when I made a meta search engine, but when I tried on expanding on it, well, I've started losing hair. =) Here's the scenario: I'm trying to parse results from Yahoo's People Search page, to "grab" the info from it. A specific link in the results contains all the info I need for each entry. A link from one such entry looks like this: psPhoneEntry.py?firstname=Adam&lastname=Collier&street=3912+Foley+Glen+Cir&city=Fenton&state=MI&zip=48430-3435&phone=8107507456 My matching pattern looks like this: $engreg = '/psPhoneEntry.py?firstname=(.*?)&lastname=(.*?)&street=(.*?)&city=(.*?)&state=(.*?)&zip=(.*?)&phone=(.*?)\">/i'; Note the "/" at the beginning, and "/i" at the end. those have always been there in other projects, and have worked. Is there anything else I'm doing wrong here? I dont get any errors, but it returns 0 matches. =) ~ Tim -- - Tim PHP Galaxy: http://www.phpgalaxy.com/ The LavaWarp Engine: http://www.phpgalaxy.com/engine.php3 BitSearch: http://www.phpgalaxy.com/bitsearch.php3 MetaWarp: http://www.phpgalaxy.com/metawarp.php3 PhotoRate: http://www.phpgalaxy.com/photorate.php3 Earn $10 per order selling these scripts on your site! http://www.phpgalaxy.com/aff/
