Split string after one character or another - php

Question

I have a file that contains many lines such as these:
2011-03-23 10:11:08 34 57 2 25,5 -
2011-03-23 10:11:12 67 54 3 3,5 -
2011-03-23 10:11:16 76 57 3 2,4 -
2011-03-23 10:11:18 39 41 2 25,5 +
Each line ends with + or -. I'd like the file content to be split after + or - sign. Lines doesn't have same number of characters.
I was trying to read the file using fgets() with auto_detect_line_endings on, but there were still many lines combined into single one:
Output example:
Output should be two lines but there is only one (you can see the "the new line" but PHP doesn't):
2011-03-23 10:11:08 34 57 2 25,5 -
2011-03-23 10:11:12 67 54 3 3,5 -
EDIT:
Code I am using to read the file
ini_set('auto_detect_line_endings', true);
$handle = fopen($filename, "r");
$index = 1;
if ($handle) {
while (($line = fgets($handle)) !== false) {
if (trim($line) != '') {
$data = preg_split('/\s+/', trim($line));
// Saving into DB...
$index++;
}
}
}
fclose($handle);

Answer 1

To make sure you get all of the possible new line combinations you should use preg_split instead:
LF = \n, CR = \r
LF: Multics, Unix and Unix-like systems (GNU/Linux, OS X, FreeBSD, AIX, Xenix, etc.), BeOS, Amiga, RISC OS and others.
CR: Commodore 8-bit machines, Acorn BBC, ZX Spectrum, TRS-80, Apple II family, Mac OS up to version 9 and OS-9
LF+CR: Acorn BBC and RISC OS spooled text output.
CR+LF: Microsoft Windows, DEC TOPS-10, RT-11 and most other early non-Unix and non-IBM OSes, CP/M, MP/M, DOS (MS-DOS, PC DOS, etc.), Atari TOS, OS/2, Symbian OS, Palm OS, Amstrad CPC
The regex would be /(\r\n|\n\r|\n|\r)/ (CR+LF or LF+CR or LF or CR):
$lines = preg_split('/(\r\n|\n\r|\n|\r)/', $string);
DEMO
If you plan on not having any empty lines (lines with white space count as empty) you can add an optional \s* to the end of your regex which will match 0 to an infinite amount of white spaces after your newlines:
$lines = preg_split('/(\r\n|\n\r|\n|\r)\s*/', $string);
DEMO
If you plan on not having any empty lines, but expect lines with white space to not count as empty, you can even simplify the regex:
$lines = preg_split('/[\n\r]+/', $string);

TRY THIS:
<?php
$input = "2011-03-23 10:11:08 34 57 2 25,5 -
2011-03-23 10:11:12 67 54 3 3,5 -
2011-03-23 10:11:16 76 57 3 2,4 -
2011-03-23 10:11:18 39 41 2 25,5 +";
// 1st explode by new line
$output = explode("\n", $input);
print_r($output);
// 2nd remove last character
$result = array();
foreach($output as $op)
{
$result[] = substr($op, 0, -1);
}
print_r($result);
OUTPUT:
Array
(
[0] => 2011-03-23 10:11:08 34 57 2 25,5 -
[1] => 2011-03-23 10:11:12 67 54 3 3,5 -
[2] => 2011-03-23 10:11:16 76 57 3 2,4 -
[3] => 2011-03-23 10:11:18 39 41 2 25,5 +
)
Array
(
[0] => 2011-03-23 10:11:08 34 57 2 25,5
[1] => 2011-03-23 10:11:12 67 54 3 3,5
[2] => 2011-03-23 10:11:16 76 57 3 2,4
[3] => 2011-03-23 10:11:18 39 41 2 25,5
)
