finding line break

[gchristen]

Hi there.

I would like my PHP script to find line breaks in a txtfile/string and only consider the text after the first line break.

Example 1 text file:

red
blue

green
yellow

The script would output:

green
yellow

Example 2 text file:

red
blue

green
yellow

violet
magenta



The script would output:

green
yellow

violet
magenta


any advice?

many thanks!

Here are a couple of options to get you started based on your examples, but by no means the best or most elegant.

$str="red
blue

green
yellow";

/**** option 1 ****/

$br=strpos($str, "\n\n");
$len=strlen($str)-$br;
$newStr=substr($str, $br, $len);

echo "newStr1: ".$newStr;

/**** option 2 ****/

$strArr=explode("\n\n", $str);
$len=sizeof($strArr);

for($i=1;$i<$len;$i++){
 $newStr2.=$strArr[$i];
}

echo "<br><br>newStr2: ".$newStr2;

We know what you mean from your example, but I think you mean blank line? There is a line break at the end of every line.

I'll give your example a try, thanks!

(and yes indeed, I mean blank line, not line break)

Cheers everyone
