this way count characters in an array but i need to count the number of rows in the textarea

seems i need to use \r then to put numbers to each row

textarea =

fdagfd
afgafdg
fdgafdg
fdgafdg
fdgafdg

result =

1 => fdagfd
2 => afgafdg
3 => fdgafdg
4 => fdgafdg
5 => fdgafdg

djjjozsi's idea is to turn the lines/rows of text into an array of lines.

It may be simpler to use [man]substr_count[/man], e.g.,

$count = substr_count($text, "\n");

You may wish to apply [man]trim/man before using substr_count().

here i use:

count rows
select a fragment from row an use it for need
generate other rows by those inserted


print("<table align=center width=800px ><tr><td class=headingadd2>");

if ($_GET['action'] == "ccommsr_results") {

$primary_info_c = "\n".$_POST["primary_info_c"];

$rows = explode("\r", $primary_info_c);


$rowcount = (substr_count($primary_info_c, "\n"))."\r\r";

$content=explode("\n",$primary_info_c);
$i=1;
foreach ($content as $value) {

$rowrow = ("{$content[$i]}");

$dotnumberingex = explode(".", $rowrow); 
$dotnumbering= strlen($dotnumberingex[0])+1;

$firstspaceex = explode(" ", $rowrow);
$firstspace= strlen($firstspaceex[0])+1;
$row=substr($rowrow,$dotnumbering,$firstspace)."\n";

$row12 = explode("=", $row);
$count1 = strlen($row12[0])+1;
$count2 = strlen($row);
$t1 = "blabla".substr($row, 0, $count1)."blablabla".$row12[1]."";
$t2 = ";".$row."";
$t3 = "ljalja"."\r\r";

//    print($rowtrackresult);

if ($i == ($rowcount)) {


	break;
	}
$rowtrackresult = $t1.$t2.$t3;
$final.=$rowtrackresult;
$i++;
}

print("<form method=\"post\" action=\"ccommsr.php?action=ccommsr_results2\">");
