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

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);

Answer 1

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);

Answer 2

$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);

Answer 3

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.

Answer 4

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