there is not just 1 word of this format in $text ... there are many words of this format.... Also, could you please explain your regex expression.. I didn;t understand it!

well, situtaion is kinda like this.... I have text(not links) which is stored in $text and in this text i have some words in this format "Step:111.Description:this is testing of &.Link:http://localhost/view.php?s=2&a=4.End" what i want to do is to replace these words with the number specified after Step: and add lines in these format at the end of the $text. Format = "[number after Step:] - <a href="link specified after Link:">(Text specified after Description:)</a> so here is the code i wrote: $rege= "~Counter:([0-9]+)\.Title:([a-z|A-Z| |&|0-9|*|,]+)\.Url:(http://localhost/view.php\?s=[0-9]+&a=[0-9]+)\.End~"; $message=preg_replace_callback($rege,create_function('$matches,$message','$message=$message."<br/>[$matches(1)]-<a href=\"$matches[3]\">$matches[2]</a>"; return "[$matches(1)]";'),$message); Errors: PHP Notice: in file /view.php(1494) : runtime-created function on line 1: Missing argument 2 for __lambda_func() Also, the regex expression is not matching the text.... I tried it matching online , it worked there but not in the code..don't know why.. Please help!

Hey Crayon Violent, i got stuck again.. How to pass some extra arguments to the callback function.. Like e.g. $matches is the only argument that is being passed currently.. what if i want to pass another variable $story to callback function so that i can append matched text to this variable $story? Any suggestions?

Hi all, What am trying to do is to find links in a string and replace them. Situation is that the link need not be separated by spaces... e.g. Contrary to popular belief, http://example.com/xyz=pqr Lorem Ipsum is not simply random texthttp://example.com/xyzzzzz=pqrs.... It has roots in a piece of classical Latin literature from 45 BC, making http://example.com/xyz=pqrrrrrrrit over 2000 years old. Richard McClintock, a Latin professor at Hampden-Sydney College in Virginia, lookedhttp://example.com/xyz=pqr should come like this(assuming replacement string is "Hello") Contrary to popular belief, Hello Lorem Ipsum is not simply random text Hello. It has roots in a piece of classical Latin literature from 45 BC, making Hello it over 2000 years old. Richard McClintock, a Latin professor at Hampden-Sydney College in Virginia, looked Hello i.e with proper spaces in the output no matter whats in the output.... Any suggestions on how to do it?

Yeah.. i got it ... Thanks again

Ok..that was a stupid question... I got it all working.. Just one small query with another regex.. preg_match_all($regexExpr2, $value, $numbers, PREG_PATTERN_ORDER); echo "$numbers[0][0] $numbers[0][1]"; is printing Array[0] Array[1] instead of 2 matches that are found in string $value.... So Confused.. Any suggestion? P.S talking about the edit you did, suppose i get two matches , each match having 2 groups that i want ultimately... How will i use it? $matches[0] will be an array containing two full match string, $matches[1] will be an array having 1st group elements of 2 complete matches and so on?? P.P.S i tried it out.. Thanku so much for your reply.. really a help.. Thanks a lot.

Hi there, thanks for the reply...i just tried things using preg_replace_callback(), i think the situation is just the same.... For every match in subject i have different elements in replacement array.. like e.g if i get two matches in subject string, than i want 1st match should be replaced with some string and other match with some other string.. If i use preg_replace_callback() , here i will be having same replacement string for all the matches.. Isn't it? Any workaround?

Thanks for the reply... Yeah i did that..(Just before you replied ) but still NO OUTPUT ... I escaped '?' and applied delimiter too '~' .. still echo "$message" ; prints nothing...... Any reason that you can see? or some mistake? P.S. Thanks for the suggestion..I'll definately do that

Hi all, I am working on a project that require finding links (of format "localhost/view.php?s={some_integer1}&a={some_integer2}" and than finding some_integer1 and some_integer2 in each link found in above string. And finally, some computation is done on basis of value of these some_integers1 and 2 and array $replacement is made ready and finally preg_replace() is caleed... The problem is i am not getting anything as output... Code: <?php $message = "hen an unknown printer took a galley of type and localhost/view.php?s=324&a=2433 scrambled it to make a type specimen book. It has survived not only five centuries, but also the leap into electronic localhost/view.php?s=33&a=222 typesetting, remaining essentially unchanged. It was popularised in the 1960s with the release of Letraset sheets containing"; $regexExpr = "localhost/view.php?s=[0-9]+&a=[0-9]+" ; preg_match_all($regexExpr, $message, $matches, PREG_PATTERN_ORDER); // some computation done on basis of values stored in $matches[0] array $regexExpr = "[0-9]+"; $i=0; foreach ($matches[0] as $key => $value ) { preg_match_all($regexExpr, $value, $forum, PREG_PATTERN_ORDER); // some computation done and $replacement array get some values here.($forum[0] array and variable $i are used in that computation). } $regexExpr = "localhost/view.php?s=[0-9]+&a=[0-9]+" ; $message = preg_replace($regexExpr, $replacement, $message); echo "$message" ; ?> Output=Nothing .. What could be the problem? Any idea... Is regex used correct? Or maybe i have used variables which are not defined earlier(but than php assume it by itself.isn't it?)

thanks a lot...

Can you explain your logic please... coz i just don have if else.. i have values of flag upto 10 and tere is different code of display for each flag. what is this isset($flag) and $flag==") ....

Actually what i want is that if flag equals 0 then the form should be like this else if flag equals 1 than form should contain completely different elements... If i do what u just wrote, than that html code betwen two php tags is getting executed no matter what is the value of flag... Any advice?

Hey thanks a lot.. So, this kind of error appears when there is some mistake in php syntax ..eh?
