Also, make sure that you make the match ungreedy with the U modifier, or
use:
(.*?)

 Subject: [PHP] Returning mutliple matches of a regex with preg_match()


 Hello all

 I have been scratching my head for the last two days about this regular
 expression problem. I would be really VERY happy if someone could help
 me!

 I have the following text in the file 'text.htm', for example:

 --

 BLOCKQUOTEP
 Cow, Cow, Cow, Cow, Cow
 Cow, Cow, Cow, Cow, Cow
 Cow, Cow, Cow, Cow, Cow
 a lot of lines
 /P/BLOCKQUOTE

 pboring stuff - we are not interested in this/p

 BLOCKQUOTEP
 Chicken, Chicken, Chicken
 Chicken, Chicken, Chicken
 Chicken, Chicken, Chicken
 more lines
 /P/BLOCKQUOTE

 pmore boring stuff - we are not interested in this/p

 BLOCKQUOTEP
 Rabbit, Rabbit, Rabbit, Rabbit

 /P/BLOCKQUOTE

 peven more boring stuff - we are not interested in this/p

 BLOCKQUOTEP
 Pig, Pig, Pig, Pig, Pig
 /P/BLOCKQUOTE

 --

 I want to return all the stuff between BLOCKQUOTEP ...
 /P/BLOCKQUOTE
 in an array. One element per match. For example, for the above text, I
 would
 like to get back an array back like this:

 array(
 Cow, Cow, Cow, Cow, Cow Cow, Cow, Cow, Cow, Cow Cow, Cow, Cow,
 Cow, Cow a
 lot of lines,
 Chicken, Chicken, Chicken Chicken, Chicken, Chicken Chicken,
 Chicken,
 Chicken more lines,
 Rabbit, Rabbit, Rabbit, Rabbit,
 Pig, Pig, Pig, Pig, Pig
 )

 I have been trying to do this with (many variations of) the following
 code:

 --

 ?PHP

 // open file
 $fd = fopen (./text.htm, r);

 // load contents into a variable
 while (!feof ($fd))
 {
 $content .= fgets($fd, 4096);
 }

 // close file
 fclose ($fd);

 // remove char returns and co.
 $content = preg_replace(/(\r\n)|(\n\r)|(\n|\r)/,  ,$content);

 // match agains regex -- this does not work correctly
 if
 (preg_match(/BLOCKQUOTEP(.*)\/P\/BLOCKQUOTE/i,$content,$matche
 s))
 {
 echo pre;
 var_dump($matches);
 echo /pre;
 }

 ?

 --

 For the above, var_dump() returns this:

 --

 array(2) {
   [0]=
   string(556) BLOCKQUOTEP Cow, Cow, Cow, Cow, Cow Cow, Cow, Cow,
 Cow,
 Cow Cow, Cow, Cow, Cow, Cow a lot of lines /P/BLOCKQUOTE  pboring
 stuff - we are not interested in this/p  BLOCKQUOTEP Chicken,
 Chicken, Chicken Chicken, Chicken, Chicken Chicken, Chicken, Chicken
 more
 lines /P/BLOCKQUOTE  pmore boring stuff - we are not interested in

 this/p  BLOCKQUOTEP Rabbit, Rabbit, Rabbit, Rabbit
 /P/BLOCKQUOTE  peven more boring stuff - we are not interested in
 this/p  BLOCKQUOTEP Pig, Pig, Pig, Pig, Pig /P/BLOCKQUOTE
   [1]=
   string(524)  Cow, Cow, Cow, Cow, Cow Cow, Cow, Cow, Cow, Cow Cow,
 Cow,
 Cow, Cow, Cow a lot of lines /P/BLOCKQUOTE  pboring stuff - we are
 not
 interested in this/p  BLOCKQUOTEP Chicken, Chicken, Chicken
 Chicken, Chicken, Chicken Chicken, Chicken, Chicken more lines
 /P/BLOCKQUOTE  pmore boring stuff - we are not interested in
 this/p  BLOCKQUOTEP Rabbit, Rabbit, Rabbit, Rabbit
 /P/BLOCKQUOTE  peven more boring stuff - we are not interested in
 this/p  BLOCKQUOTEP Pig, Pig, Pig, Pig, Pig 
 }

 --

 Clearly not what I want.

 Is my approach here incorrect? Or is it indeed possible to construct a
 regex
 to do what I want (with just one pass of the text)?

 Thank you in advance.

 :-))

Re: [PHP] Returning mutliple matches of a regex with preg_match()

2002-03-21 Thread Stefen Lars


Thank you James and Niklas.

Here is the code that I need:

?PHP

// open file
$fd = fopen (./text.htm, r);

// load contents into a variable
while (!feof ($fd))
{
$content .= fgets($fd, 4096);
}

// close file
fclose ($fd);

// remove char returns and co
$content = preg_replace(/(\r\n)|(\n\r)|(\n|\r)/,  ,$content);

if 
(preg_match_all(/BLOCKQUOTEP(.*)\/P\/BLOCKQUOTE/U,$content,$matches))
{
echo pre;
var_dump($matches);
echo /pre;
}

?

This returns exactly what I want (see my original post to learn what that 
is.)

Thank again.

:-))

use preg_match_all();
the var_dump($matches); to see what happened.

Best regards,
