That isn't going to work.  You missed your delimiters in the first arg
for preg_match().  It requires beginning and ending delimiters around
the regex.

I would try this

$lines = preg_split('|[\n\r]|', $content);
$filtered = '';
foreach ( $lines as $line ) {
  $txt = trim( $line );
  if ( ! empty( $txt ) ) {
  $filtered .= $line;
  }
}

It is much more intense to do the preg_match inside a loop.  You should
only do it once, then use less intense function calls inside the loop.

warning: completely untested...  have no example input you are using...

The empty strings are forcing the parameter to be used as a string,
otherwise the line would be translated as something like this:

$dtd = preg_replace( "/\n/", \n, $dtd);

Notice how that newline character is actually just the character by
itself, and is not a string.

Obviously, the exact end of line character will differ from system to
system, but this is a simple example of exactly why you had to
concatenate the PHP_EOL with those empty strings.

Re: [PHP] how to strip empty lines out of a txt using preg_replace()

2009-09-04 Thread Ralph Deffke
and this is the PHP_EOL solution:
$dtd = preg_replace( "/[". PHP_EOL . "]+/", "". PHP_EOL . "", $dtd);

dont ask me why two empty strings are needed to surround the PHP_EOL but its
does it.

Why this works? we have got an INTERPRETER here any \n is transtlated into
0x0D an \r into 0x0A so the pattern does not reach prce as '\n' hehe

Re: [PHP] how to strip empty lines out of a txt using preg_replace()

2009-09-04 Thread Sam Stelfox
The following snippet is untested and using Ash's regex (it is accurate 
\s matches any white space). $content is what is getting stripped of the 
new lines and $filtered is the cleansed output. See if that does the 
trick for you.


$lines = str_split(PHP_EOL, $content);
$filtered = '';
foreach ($lines as $line) {
   if (!preg_match('^\s*$', $line)) {
  // Splitting on the PHP_EOL characters cause it to be removed be 
sure to put it back

  $filtered .= $line . PHP_EOL;
   }
}

like this:

Are the lines actually whitespace, or are they actually  tags that

The PHP_EOL is system dependent. If you want a solution that works on every
type of file you have to code it yourself. Here you have a function made
some time ago.
Maybe you can improve it.

If you want the result as a text format you can implode( PHP_EOL, $buffer )
Hope this helps you.

function explode($code)
{
$lines = array();
$buffer = '';

for($i=0, $len = strlen($code); $i<$len; ++$i)
switch( $code{$i} )
{
case "\r":
case "\n":
if( $i+1 == $len )
break 2;

if( "\r" == ($next = $code{ $i+1 }) || "\n" == $next )
{
++$i;
}

$lines[] = $buffer;
$buffer = '';
break;
default:
$buffer .= $code{$i};
}

if( '' !== $buffer );
$lines[] = $buffer;

return $lines;
}

If it is just made up of \t and \n then \s in the regex should match it,
as it's meant to match just whitespace characters. Where are you getting

Re: [PHP] how to strip empty lines out of a txt using preg_replace()

2009-09-04 Thread Ralph Deffke
the problem is some have got \t\n
some are just \n\n\n

using PHP_EOL is a must

I thing must be something with the /../sm attributes to the regex, spend
like half an hour, but didn't get it, I'm running against a dead line,
doesn't seem to be that easy if regex is not the everydays need u have

Are the lines actually whitespace, or are they actually  tags that
are inserting lines to format the page for HTML display?
