如何将文本文件的每一行设置为变量？

Question

I got a simple php script that is storing the content of POST in to a text file. data.txt looks like this:

Something - Line1
Something - Line2
Something - Line3
Something - Line4

I'm trying to figure out the best way to set each line as a variable e.g.

$line1 = "Something - Line1";
$line2 = "Something - Line2";
$line3 = "Something - Line3";
$line4 = "Something - Line4;"

so I can use it for further processing. Please note that the numbers of line can change. Any ideas? :-)

Thanks!

Best to use an array. Check out file():

$lines = file('/path/to/file.txt');

Then you access the lines starting from 0:

echo $lines[0];
echo $lines[1];
//etc...

Or loop through them:

foreach($lines as $line) {
    echo $line;
}
