I have txt file its content like this
Hello
World
John
play
football
I want to delete the new line character when reading this text file, but I don't know how it look like the file .txt and its encoding is utf-8
Just use file
function with FILE_IGNORE_NEW_LINES
flag.
The file
reads a whole file and returns an array contains all of the file lines.
Each line contains new line character at their end as default, but we can enforce trimming by FILE_IGNORE_NEW_LINES
flag.
So it will be simply:
$lines = file('file.txt', FILE_IGNORE_NEW_LINES);
The result should be:
var_dump($lines);
array(5) {
[0] => string(5) "Hello"
[1] => string(5) "World"
[2] => string(4) "John"
[3] => string(4) "play"
[4] => string(8) "football"
}
There are different kind of newlines. This will remove all 3 kinds in $string
:
$string = str_replace(array("\r", "\n"), '', $string)
If your going to be putting the lines into an array, an assuming a reasonable file size you could try something like this.
$file = 'newline.txt';
$data = file_get_contents($file);
$lines = explode(PHP_EOL, $data);
/** Output would look like this
Array
(
[0] => Hello
[1] => World
[2] => John
[3] => play
[4] => football
)
*/
For PHP's file()
function, the FILE_IGNORE_NEW_LINES
flag is the way to go. In case you get your array in another way, like with gzfile()
, do this:
// file.txt
$lines = file('file.txt', FILE_IGNORE_NEW_LINES);
// file.txt.gz
$lines = gzfile('file.txt.gz');
$lines = array_map(function($e) { return rtrim($e, "\n\r"); }, $lines);
I note that the way it was pasted in the question, this text file appears to have space characters at the end of each line. I'll assume that was accidental.
<?php
// Ooen the file
$fh = fopen("file.txt", "r");
// Whitespace between words (this can be blank, or anything you want)
$divider = " ";
// Read each line from the file, adding it to an output string
$output = "";
while ($line = fgets($fh, 40)) {
$output .= $divider . trim($line);
}
fclose($fh);
// Trim off opening divider
$output=substr($output,1);
// Print our result
print $output . "\n";
