[PHP] Need help with RegEx
Hello Everyone,
I am having a bit of problems wrapping my head around regular expressions. I
thought I had a good grip on them but, for some reason, the expression I've
created below simply doesn't work! Basically, I need to retreive all of the
text between two unique and specific tags but I don't need the tag text. So
let's say that the tag is
THIS IS A TEST
I would need to retreive THIS IS A TEST only and nothing else.
Now, a bit more information: I am using cURL to retreive the entire contents
of a webpage into a variable. I am then trying to perform the following
regular expression on the retreived text:
$trans_text = preg_match("\/(.+?)<\/div>/");
The problem is that when I echo the value of $trans_text variable, I end up
with the entire HTML of the page.
Can anyone clue me in to what I am doing wrong?
Thanks,
Anthony

explode it
I'm having quite the difficulty to comprehend the regexp myself, but as a
training, go ahead.

Re: [PHP] Need help with RegEx
I'm no regex guru but something goes wrong here.
First of you miss the second parameter in preg_match
int preg_match ( string pattern, string subject [, array &matches [, int flags
[, int offset]]] )
If you need the text from two unique tags it should not be to hard:
$test = "THIS IS A TEST";
preg_match("/(.+?)<\/tag>/", $test, $matches);
print_r($matches);

This is hardly the code you're actually using[1], can you please
provide a piece of real code?

[PHP] PHP - grabbing a thumb from FLV's (function)
i wanted to get my server to grab a thumbnail (video capture) of an FLV
using PHP, and ffmpeg-php is not an option (at the moment, can't spare the
possible downtime, many money-making sites involved).
i installed ffmpeg. Fedora Core 4 users try this:
yum install ffmpeg
I went a more circuitous route and installed Subversion (SVN) (google it),
THEN installed ffmpeg using the link on their download page. (get it,
configure it, make it)
Then, like i do with imageMagick, i use a system() call to ffmpeg.
NOTE: (i had to put the full path to ffmpeg (usr/local/bin/ffmpeg) in my
system call, this messed me up for a bit)
here's my impromptu function (have to pass the FLV file, width, height,
hour, min, sec, append (any value you want to put on the end of the
resulting jpg's filename)):
function
flvThumb($file,$width=50,$height=50,$hour=00,$min=00,$sec=01,$append) {
if ($append == "") {
$append = time();
}
if ($file == "" or !is_file($file)) {
return false;
}
$width = eregi_replace("[^0-9]","",$width);
$height = eregi_replace("[^0-9]","",$height);
if ($width == "") {
$width = 50;
}
if ($height == "") {
$height = 50;
}
$hour = eregi_replace("[^0-9]","",$hour);
$min = eregi_replace("[^0-9]","",$min);
$sec = eregi_replace("[^0-9]","",$sec);
if (strlen($hour) == 1) {
$hour = "0" . $hour;
}
if (strlen($min) == 1) {
$min = "0" . $min;
}
if (strlen($sec) == 1) {
$sec = "0" . $sec;
}
$try = explode(".",$file);
$ext = array_pop($try);
$desig = implode(".",$try);
$thumbname = $desig . "_" . $append . "." . "jpg";
$varmake = @system("/usr/local/bin/ffmpeg -i $file -vcodec png -vframes 1
-an -f rawvideo -s " . $width . "x" . $height . " -ss " . "$hour" . ":" .
"$min" . ":" . "$sec" . " -y " . "$thumbname",$retval);
$tmp = @stat($thumbname);
if ($tmp['size'] == 0) {
@unlink($thumbname);
return false;
}
if ($retval != 0) {
return false;
} else {
return $thumbname;
}
}
if it returns anything but false, you may have a problem. of course, the
problem may be with the function and application.
i know that improvements can be made, but i wish i had seen this before i
started trying to figure everything out. i like having a starting point.
(i'm sending this to my gmail for my 'reference archive')
HOPE THIS HELPS SOMEONE
(plz don't burn me)

p.s. it only just now strikes me that many other video formats can be
thumbnailed. mpg, wmv, mov, avi, etc this really changes the way i'm
thinking about my sites. i was using a desktop client to make thumbnails,
and it's a good one, but to have ur server do it for you...that just makes
it that much easier to add content, and thusly, that much more likely for me
to add content because i'm a lazy wanker.

Using the tags you describe here, and assuming the source html is in the
variable $source_html, try this:
$trans_text = preg_replace("/(.*?)()(.*?)(<\/div>)(.*?)^/s","$3",$source_html);
how this breaks down is:
opening quote for first parameter (your MATCH pattern).
open regex match pattern= /
first atom (.*?) = any or no leading text before ,
the ? makes it non-greedy so that it stops after finding the first match.
second atom () = the opening tag you are looking for.
third atom (.*?) = the text you want to strip out, all text even if nothing is
there, between the 2nd and
4th atoms.
fourth atom (<\/div>) = the closing tag of the div tag pair.
fifth atom (.*?) = all of the rest of the source html after the closing tag up
to the end of the line ^,even if there is nothing there.
close regex match pattern= /s
in order for this to work on html that may contain newlines, you must specify
that the . can represent newline characters, this is done by adding the letter
's' after your regex closing /, so the last thing in your regex match pattern
would be /s.
end of string ^ (this matches the end of the string you are matching/replacing
, $source_html)
closing quote for first parameter.
The second parameter of the preg_replace is the atom # which contains the text
you want to replace the text matched by the regex match pattern in the first
parameter, in this case the text we want is in the third atom so this parameter
would be $3 (this is the PHP way of back-referencing, if we wanted the text
before the tag we would use atom 1, or $1, if we want the tag itself we use $2,
etc basically a $ followed by the atom # that holds what we want to replace the
$source_html into $trans_text).
The third parameter of the preg_replace is the source you wish to match and
replace from, in this case your source html in $source_html.
after this executes, $trans_text should contain the innerText of the tag pair from $source_html, if there is nothing
between the opening and closing tags, $trans_text will == "", if there is only
a newline between the tags, $trans_text will == "\n". IMPORTANT: if the text
between the tags contains a newline, $trans_text will also contain that newline
character because we told . to match newlines.
I am no regex expert by far, but this worked for me (assuming I copied it
correctly here heh)
There are doubtless many other ways to do this, and I am sure others on the
list here will correct me if my way is wrong or inefficient.
I hope this works for you and that I haven't horribly embarassed myself here.
Good luck :)

Re: [PHP] Need help with RegEx
I just realized I neglected to explain a couple of things here, sorry...
My method will only work for the FIRST occurrence of the div tag pair in
$source_html.
The reason this method works is that you are telling preg_replace to replace
everything that matches the match pattern, with just what is contained in the
third atom of the match pattern. Since we are matching everything between the
start of $source_html and the end of $source_html (the (.*?) atom at the
beginning, and the (.*?)^ atom at the end) your return value ends up being $3,
or the contents of the third atom of the match pattern, which represents the
text between the opening tag and closing tag of your div element.
hope this makes sense, I'm writing this at 5am heh
Cheers,
Michael

RE: [PHP] Need help with RegEx
The example provided didn't work for me. It gave me the same string without
anything modified.
I am also looking for this solution to strip out text from some XML response
I get from posting data to a remote server. I can do it using substring
functions but I'd like something more compact and portable. (A one-liner
that I could modify for other uses as well)
Example 1:
16664 Rejected: Invalid LTV
Example 2:
Unable to Post, Invalid Information
I want what is inside the tags.
Does anyone have a working solution how we can get the text from inside
these tags using regex?
Much appreciated,
B

[PHP] pear xmlrpc question
I have a simple helloWorld example in a xmlrpc version.
The xmlrpc implementation that i have used is the pear package XML_RPC
1.5.1.
The problem ocurrs when the server send back the response, i always
receive the error "Invalid return payload:enable debuggin..".
With debug enabled the output is this:
---GOT---

*Function Call:* helloWorld( Jose )
*Sent XML Message:*

*Return Value:*

The client source code:
require_once("XML/RPC.php");

$function = "helloWorld";
$p1 = new XML_RPC_Value($nombre, "string");
$params = array();
$params[] = $p1;
$message = new XML_RPC_Message($function, $params);
$client = new XML_RPC_Client("/pruebas/servicio.php", "www.wiloc.srv", 80);
$client->setDebug(true);
$result = $client->send($message);
echo "Function Call: $function( $nombre )";
echo "Sent XML Message:";
echo "" . htmlentities($message->serialize()). "";
$value = $result->value();
echo "Return Value: $value ";
echo "Received XML Message:";
echo "" . htmlentities($result->serialize()) . "";
And the server source code:
**
require_once("XML/RPC/Server.php");
$getnamelength_sig2 = array(array("string","string"));
$getnamelength_doc2 = "Hola mundo en xmlrpc";
function helloWorld($name)
{
$name1 = $name->getParam(0);
$result = new XML_RPC_Value("Hola ".$name1->getval(), "string");
return new XML_RPC_Response($result);
}
$map = array("helloWorld" =>
array("function" => "helloWorld",
"signature" => $getnamelength_sig2,
"docstring" => $getnamelength_doc2));
$server = new XML_RPC_Server($map,0,1);
$server->service();
What is wrong in this very simple example?
Thanks a lot,
Jose.

[PHP] preg_match to preg_replace
Hi guys,
I have a sample string "[hp-ex][log]peter[hall o]" that I need to process. I
need to remove the [] and separate the sections with a space. If there are
more then one [] part the first part should be bold (add around it).
I have a solution that is working very well, but am thinking that I can do
this with preg_replace directly, what do you think? The final output is
always found in $thestr. Can all this be done with one preg_replace?
";
$str = "[hp-ex][log]peter[hall o]";
preg_match_all("/\[(.+?)\]/", $str, $matches);
print_r($matches);
$m1 = $matches[0];
$m2 = $matches[1];
if(count($m1)>1) {
$m2[0] = "$m2[0]";
$thestr = implode(" ", $m2);
} elseif(count($m1)==1) {
$thestr = $m2[0];
} else $thestr = "";
echo $thestr;
echo "";
?>

You are absolutely correct, this is what I get for not testing it explicitly :(
My most sincere apologies to the OP and the list, there is an error in my
example (see below for correction)
I have cut and pasted from further down in the quoted message, for
convenience

The End of string symbol ^ should not be included. I tested the above function
without the ^ and it worked for me. below is the TESTED version:
$trans_text = preg_replace("/(.*?)()(.*?)(<\/div>)(.*?)/s","$3",$source_html);

The End of string symbol ^ should not be included. I tested the above function

$trans_text = preg_replace("/(.*?)()(.*?)(<\/div>)(.*?)/s","$3",$source_html);

[PHP] flash/php file uploader
Hi Sorry if this is considered off topic, but do you know of any code examples/libs with a flash/php file uploader with progress bar? I've googled for a while but the scripts I find won't work.

One way of overcoming this is to use a combination of AJAX+Perl/CGI instead of PHP. (Most LAMP servers can also run CGI scripts) An example of an upload progress bar written in AJAX+CGI is Filechucker. Our company purchased a license for use on one of our sites, its cheap and works great. I have also seen custom PHP extensions that add the callback method, but they require you to recompile PHP and in the end we decided to go with the CGI solution as it was pretty much plug and play. -B -- PHP General Mailing List (http://www.php.net/) To unsubscribe, visit: http://www.php.net/unsub.php
