PHP for read txt file line just upon sign "#"

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);

And in case you really want the full text after the #, http://de3.php.net/manual/en/function.strstr.php — Gordon, Jun 20 '11 at 15:27

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);

Thanks to all. Very useful tips. One more thing, can I put each data value on a $_SESSION variable and give names like $_SESSION['peso'] for the first $_SESSION['clientID'] for the second...? – CMartins Jun 20 '11 at 15:57

$file_handle = fopen("texto.txt", "r");
$numlinha = 0;
while (!feof($file_handle)) {
   $line = fgets($file_handle);
   $parts = explode("#", $line);
   $parts[0] // part before the # in this line
   $parts[1] // part behind the # in this line
   $numlinha++;
   echo $numlinha . ". " . $line . "</br></br>";
}
fclose($file_handle);

You could use: $data = explode(";#;", $line); And then do your processing on $data[1] instead of $line.

This assumes that ;#; is unique on each line...

Note that using string position testing (strpos()) and substr() to extract the part of the string would be more resource consuming, I believe, than just taking the line you already read and splitting it at the exact known delimiter, which in this case is ;#;.

The other examples posted assume that # will be only on the line once, or at least the divide will be the first # in the line. Using ;#; would make it more unique, and your result can be processed by the str_getcsv() function if you needed to break it down into an array of values for other uses.

You can use the explode function, to split the string in two parts using the "#" delimiter
