I need help with a PHP regular expression that would match the sample shortcode below:
[smiley set_name="Happy" filename="smiling.gif"]
I'd like to extract "Happy" and "smiling.gif" from the above shortcode. I would highly appreciate your help. Thanks in advance.
I'm not sure how much of your string you can assume to know but maybe something like:
/\[smiley set_name="([\w\s]+)" filename="(\w+.gif|jpg|png|jpeg)"\]/
So your code may look like:
$string = '[smiley set_name="Happy" filename="smiling.gif"]';
preg_match('/\[smiley set_name="([\w\s]+)" filename="(\w+.gif|jpg|png|jpeg)"\]/', $string, $matches);
var_dump($matches);

I have the string with parameters like
"Hello, %{user}. Please, give %{client} a knife".
So, please, I'm not familiar with regular expressions, and I need to have php construction which can get list of parameters from a string. Please, help me, I hope you can. Thank you.
$str = "Hello, %{user}. Please, give %{client} a knife".
preg_match_all("/%\{(.*?)\}/", $str, $matches);
print_r($matches);
there are a lot of topics like this one but i don't know what the error i tried a lot
so this is the original text
onclick="NewWindow('http://google.com','name','800','600','yes');return false">
this is my code
$re1='(onclick)';
$re2='(=)';
$re3='(.)';
$re4='(NewWindow)';
$re5='(\\()';
$re6='(.)';
$re7='((?:http|https)(?::\\/{2}[\\w]+)(?:[\\/|\\.]?)(?:[^\\s"]*))';
$c=preg_match_all ("/".$re1.$re2.$re3.$re4.$re5.$re6.$re7."/is", $txt, $matches);
print_r($matches);
any one can help me to get the url using regular expression and php??
what is the wrong with this code?
Regards
preg_match("/NewWindow\('([^']*)'/",$txt, $matches);
matches[1] contains the url
is it what you need ?
(edit: put in code block because a parenthesis was not escaped correclty
This should work:
preg_match("/onclick=\"NewWindow\('(.*)','n/",$txt,$matches);
I'd use non-greedy matching for this:
preg_match("/onclick=\"NewWindow\('(.*?)'/", $txt, $matches);
Based on your description, the regex I would use, would be:
/(?<=NewWindow\(\').*(http://|https://)[^\'\"]*/i
or
/(?<=onclick=\"NewWindow\(\').*(http://|https://)[^\'\"]*/i
A great tool for testing your regex is: http://gskinner.com/RegExr/
It outputs just the url and only does so if it is preceded by "NewWindow('" in the first example or "onclick="NewWindow('", which means, in your case, 'http://google.com').
I need to get string from comment in HTML file, I was trying to do it with DOM, but I didn't find good solution with this method.
So I want to try it with regular expressions, but I can't find satisfactory solution. Please, can you help me?
This is what I need:
<!--adress-"String here I need to get"-->
Thanks in advance for answer
Look into $matches after this code
preg_match('~<!--adress-"(.*?)"-->~msi', $string, $matches);
HTML comments are regular; you can just match <!--adress-"([^">]+)"--> and get the first group.
This assumes that the comments are always well-formed and always have a quoted string containing no quotes.
It will be more accurate:
$regex = '<!--(.+?)-"{0,1}(.+?)"{0,1}-->';
preg_match_all($regex, $html, $matches_array);
Just do the var_dump($matches_array) and see results.
Hi I am trying to use preg_match_all() to extract the number in bold out of an image URL...
http://profile.ak.fbcdn.net/hprofile-ak-snc4/174844_39677118233_8277870_t.jpg
Could someone please help me with the regular expression needed as I am stumped.
I've used this so far:
preg_match_all("(http://profile.ak.fbcdn.net/hprofile-ak-snc4/.*_t.jpg)siU", $this->html, $matching_data);
return $matching_data[0];
}
Which is just giving me an array of the full links.
Hope someone can help, thanks!!!
This will give you all occurrences:
$matches = preg_match_all ('!/hprofile-ak-snc4/[0-9]+_([0-9]+)[^/]+?\.jpg!i', $txt);
print_r ($matches);
Number you have bolded should be contained in $matches[$n][3]...
preg_match_all("#http://profile\.ak\.fbcdn\.net/(.*?)/([0-9]+)_([0-9]+)_([0-9]+)_t\.jpg#is", $string, $matches);
print_r($matches);
Try this:
([a-z][a-z0-9+\-.]*:(//[^/?#]+)?)?
([a-z0-9\-._~%!$&'()*+,;=:#/]*)
(?:(?:\d+_)(\d+)(?:_\d+))\3
I've separated it out onto multiple lines for easier reading. You will want to use capture group 4
Or (just minimized it a bit)
(?:[a-z][a-z0-9+\-.]*:(?://[^/?#]+)?)?
([a-z0-9\-._~%!$&'()*+,;=:#/]*)
(?:(?:\d+_)(\d+)(?:_\d+))\1
and use capture group 2
I have a string Like this:
MyText (1,151)
I would like to get with regex only the value inside (), in this case only: 1,151.
I know it is simple but I am not good with regex.
Thanks!
A nearly identical question was just asked. There are solutions in there that will work for you ;)
This will work:
if (preg_match($str, '/\(([^)]*)\)/', $matches))
{
$content = $matches[1];
}
