Question

I have this txt file structure:

"data";"data";"data";#;"my data";"my data";"my data"
"data";"data";"data";#;"my data";"my data";"my data"
"data";"data";"data";#;"my data";"my data";"my data"

I need to read this file data just after the # sign.
My PHP code just for read the entire line.

$file_handle = fopen("texto.txt", "r");
$numlinha = 0;
while (!feof($file_handle)) {
   $line = fgets($file_handle);
   $numlinha++;
   echo $numlinha . ". " . $line . "</br></br>";
}
fclose($file_handle);

You can use strpos function to find position of first # char in your line.

$file_handle = fopen("texto.txt", "r");
$numlinha = 0;
while (!feof($file_handle)) {
   $line = fgets($file_handle);
   $cpos = strpos($line, '#');
   if ($cpos !== FALSE) {
       $line = substr($line, 0, $cpos);
   }
   $numlinha++;
   echo $numlinha . ". " . $line . "</br></br>";
}
fclose($file_handle);
