在每行的末尾添加一个字符串，但不是在第一行

Question

I am trying to add a string to the end of eachline. So far this works. However I dont want the string to be added to the end of the first line. How can I do this?

So far i have got:

<?php

$EOLString="string \n";
$fileName = "file.txt";
$baseFile = fopen($fileName, "r");
$newFile="";
while(!feof($baseFile)) {
    $newFile.= str_replace(PHP_EOL, $EOLString, fgets($baseFile));
}
fclose($baseFile);
file_put_contents("newfile.txt", $newFile);

$bingName = "newfile.txt";
$bingFile = fopen($bingName, "a+");
fwrite($bingFile,$EOLString);
fclose($bingFile);

?>

I have also tried to loop it by doing this:

<?php

$EOLString="string \n";
$fileName = "file.txt";
$baseFile = fopen($fileName, "r");
$newFile="";
$x = 0;
while(!feof($baseFile)) {
    if ($x > 0) {
        $newFile.= str_replace(PHP_EOL, $EOLString, fgets($baseFile));
    }
    $x++;
}
fclose($baseFile);
file_put_contents("newfile.txt", $newFile);

$bingName = "newfile.txt";
$bingFile = fopen($bingName, "a+");
fwrite($bingFile,$EOLString);
fclose($bingFile);

?>

So the end result would look like:

firstonestring secondonestring thirdonestring

and so on.

I hope you can help me!

Answer 1

Just add a counter to your loop:

$counter = 0;
while(!feof($baseFile)) {
    $line = fgets($baseFile)
    if($counter++ > 0){
        $newFile.= str_replace(PHP_EOL, $EOLString, $line);
    }else{
        $newFile.= $line . "\n";
    }
}

Also, you seem to be writting the new file, only to reopen it and append more data. There is no need to do that, just append to the contents before you write it the 1st time:

fclose($baseFile);
file_put_contents("newfile.txt", $newFile . $EOLString);

//$bingName = "newfile.txt";
//$bingFile = fopen($bingName, "a+");
//fwrite($bingFile,$EOLString);
//fclose($bingFile);

Alternativly, you can just read in the whole file, split into lines, and rejoin:

$EOLString="string \n";
$lines = explode("\n", file_get_contents("file.txt"));
$first = array_shift($lines);
file_put_contents("newfile.txt", $first . "\n" . implode($EOLString, $lines) . $EOLString);
//done!

By using a flag

$first = TRUE;//set true first time
while (!feof($baseFile)) {
    $line = fgets($baseFile);
    if (!$first) {// only enter for false
        $newFile.= str_replace(PHP_EOL, $EOLString, $line);
    }
    $first = FALSE;// set false except first
}
