get string from file by line

[scorpion]

Does anybody know how to open a file such that you can retrieve each line using a number?

e.g. a[1] = string on the first line of the file
a[2] = string on the second line of the file, etc..

I don't think (could be wrong) that there's a built in way to do that, but you could try the following:

$i = 1;

while($fp &&!feof($fp))
{
$myArray[$i] = trim(fgets($fp));
$i++;
}

after that you can use the array and lookup any line numbers

Note: depending on line length (when size of a line is over a certain amount of kb), there might be issues (more info here -> fgets [php.net])

In PHP [php.net] you could use file [php.net] to read an entire file into an array. In Perl [perl.com] you can simply use the angle operator in list context.
