PHP Displaying Strange Chinese Characters? - php

I am having a few problems with this code, one is that the proxies are not being displayed on a new line for each one.
Two is that instead of the "" being displayed these weird chinese characters are being displayed 䈼㹒
<?php
$data = file_get_contents("http://proxylists.connectionincognito.com/proxies_657.txt");
//var_dump($data);
$lines = explode("/n", $data);
foreach($lines as $line)
{
echo $line;
echo "<BR>";
}
?>

Try to explode by "\n" instead of "/n".
The Chinese charakters are there because the file is encoded in UTF-16, so you need to do this:
$data = mb_convert_encoding($data,'UTF-8','UTF-16');
before you start to work with the data. I made a working example here:
http://www.servisio.com/test.html
It contains these four lines:
$data = file_get_contents("http://proxylists.connectionincognito.com/proxies_657.txt");
$data = mb_convert_encoding($data,'UTF-8','UTF-16');
$lines = explode("\n", $data);
foreach($lines as $line) echo $line.'<br>';

including leading whitespaces when using fgets in php

I am using PHP to read a simple text file with the fgets() command:
$file = fopen("filename.txt", "r") or exit('oops');
$data = "";
while(!feof($file)) {
$data .= fgets($file) . '<br>';
}
fclose($file);
The text file has leading white spaces before the first character of each line. The fgets() is not grabbing the white spaces. Any idea why? I made sure not to use trim() on the variable. I tried this, but the leading white spaces still don't appear:
$data = str_replace(" ", " ", $data);
Not sure where to go from here.
Thanks in advance,
Doug
UPDATE:
The text appears correctly if I dump it into a textarea but not if I ECHO it to the webpage.
Function fgets() grabs the whitespaces. I don't know what you are exactly doing with the $data variable, but if you simply display it on a HTML page then you won't see whitespaces. It's because HTML strips all whitespaces. Try this code to read and show your file content:
$file = fopen('file.txt', 'r') or exit('error');
$data = '';
while(!feof($file))
{
$data .= '<pre>' . fgets($file) . '</pre><br>';
}
fclose($file);
echo $data;
The PRE tag allows you to display $data without parsing it.
Try it with:
$data = preg_replace('/\s+/', ' ', $data);
fgets should not trim whitespaces.
Try to read the file using file_get_contents it is successfully reading the whitespace in the begining of the file.
$data = file_get_contents("xyz.txt");
$data = str_replace(" ","~",$data);
echo $data;
Hope this helps
I currently have the same requirement and experienced that some characters are written as a tab character.
What i did was:
$tabChar = ' ';
$regularChar = ' '
$file = fopen('/file.txt');
while($line = fgets($file)) {
$l = str_replace("\t", $tabChar, $line);
$l = str_replace(" ", $regularChar, $line);
// ...
// replacing can be done till it matches your needs
$lines .= $l; // maybe append <br /> if neccessary
}
$result = '<pre'> . $lines . '</pre>';
This one worked for me, maybe it helps you too :-).

Is there an alternative for file_get_contents?

I tried this but getting only one character from file comments.txt
I want random lines one by one .. file_get_contents disabled also urlencode
$f_contents = file_get_contents("comments.txt");
$line = $f_contents[array_rand($f_contents)];
$messages = $line;
$messages = urlencode($messages);
You can simplify it like ..
<?php
$arr = file('comments.txt',FILE_IGNORE_NEW_LINES);
shuffle($arr);
foreach($arr as $v)
{
echo $v."<br>";
}
The above code prints random lines from your text file one by one.

Don't echo things with certain characters

I have a php program that looks at a log file and prints it to a page (code below). I don't want the user of said website to be able to look at any line containing a /. I know I could use trim to delete certain characters, but is there a way to delete the entire line? For example, I want to keep something like "Hello" and delete something like /xx.xx.xx.xx connected. All the lines I wish to delete have the same common key, /. Peoples names in said log file have <>s around them, so I must use htmlspecialcharacters
$file = file_get_contents('/path/to/log', true);
$file = htmlspecialchars($file);
echo nl2br($file);
Thanks for your help!
EDIT:
Thanks for all of the answers, currently tinkering with them!
EDIT2:
final code:
<?php
$file = file_get_contents('/path/to/log', true);
// Separate by line
$lines = explode(PHP_EOL, $file);
foreach ($lines as $line) {
if (strpos($line, '/') === false) {
$line = htmlspecialchars($line . "\n");
echo nl2br($line);
}
}
?>
Do you mean, like this?
$file = file_get_contents('/path/to/log', true);
// Separate by line
$lines = explode(PHP_EOL, $file);
foreach ($lines as $line) {
if (strpos($line, '/') === false) {
// If the line doesn't contain a "/", echo it
echo $line . PHP_EOL;
}
}
For anyone wondering, PHP_EOL is the PHP constant for "end of line" and promotes consistency between different systems (Windows, UNIX, etc.).
If you are iterating through the file line by line you can check with preg_match if the line contains /character and skip the echo if it does. If not, first split them at new line and iterate over that array.
If you don't want to split the file you can probably use preg_replace with a regexp such as (^|\n).*/.*(\n|$) and replace with empty string.
Use the str_replace function -
http://php.net/manual/en/function.str-replace.php. Alternate solution (before escaping the special characters) -
/* pattern /\/[0-9]+\.[0-9]+\.[0-9]+\.[0-9]+\sconnected/ = /xx.xx.xx.xx connected */
/* pattern will be replaced with "newtext" */
$file = file_get_contents("/path/to/log", true);
$lines = explode("\n", $file);
foreach ($lines as $line)
$correctline = preg_replace( '/\/[0-9]+\.[0-9]+\.[0-9]+\.[0-9]+\sconnected/', 'newtext', $line );
echo $correctline;
}
<?php
$file = file_get_contents("/path/to/log", true);
$lines = explode("\n", $file);
foreach ($lines AS $num => $line)
{
if ( strpos($line, "/") === false ) // Line doesn't contain "/"
{
echo htmlspecialchars($line) . "\n";
}
}
?>

Reading text after a certain character in php

Okay so I have a text file and inside of the text file I have these lines:
IP = 127.0.0.1
EXE = Client.exe
PORT = 8080
TITLE = Title
MAINT = False
MAINT-Message = This is the message.
what I am wanted to do is get the 'False' part on the fifth line.
I have the basic concept but I can't seem to make it work. This is what I have tried:
<?php
$file = file_get_contents('LauncherInfo.txt');
$info = explode(' = ', $file);
echo $info[5];
?>
And with this I get a result but when I echo $info[5] it gives me 'False Maint-Message' so it splits it but it only splits at the = sign. I want to be able to make it split at the where I have pressed enter to go onto the next line. Is this possible and how can I do it?
I was thinking it would work if I make it explode on line one and then do the same for the second line with a loop until it came to the end of the file? I don't know how to do this though.
Thanks.
I think you're looking for the file(), which splits a file's contents into an array of the file's lines.
Try this:
$file = file('LauncherInfo.txt');
foreach ($file as $line) {
if ($line) {
$splitLine = explode(' = ',$line);
$data[$splitLine[0]] = $splitLine[1];
}
}
echo $data['MAINT'];
Just in case you were curious, since I wasn't aware of the file() function. You could do it manually like this
<?php
$file = file_get_contents('LauncherInfo.txt');
$lines = explode("\n", $file);
$info=array();
foreach($lines as $line){
$split=explode(' = ',$line);
$info[]=$splitline[1];
}
echo $info[5];//prints False
?>

Parsing file in PHP; how to detect newlines?

I've got a problem where I'm trying to read a text file like this:
Joe
Johnson
Linus
Tourvalds
and while parsing it in php, I need to be able to detect the newlines. I'm trying to correctly define $newline. I'm looping through the array of lines in the $file variable.
while($line = next($file))
if($line = $newline)
echo "new line";
The problem is that I can't seem to match the newline character. I know that it is actually showing up in the $file array, because this:
while($line = next($file))
echo $line;
outputs the file verbatim, with newlines and all. I've already tried "\n", " ", and I'm not sure what to try next. A little help?
$file = file("path/to/file.txt");
// Incase you need to call it multiple times ...
function isNewLine($line) {
return !strlen(trim($line));
}
foreach ($file as $line) {
if (isNewLine($line)) {
echo "new line<br/>";
}
}
Maybe something like this would work for you?
while($line = next($file)) {
if(in_array($line, array("\r", "\n", "\r\n"))) {
echo "new line";
}
}
I think this solution may help you guys. This works if you are parsing csv that is generated from Mac or windows. Reading csv with multilines created in Mac, gives problem i.e. you cannot read each line in a loop but all csv data is read as single line.
This problem is solved by following solution:
//My CSV contains only one column
$fileHandle = fopen("test.csv",'r');
$codesArray = array();
count = 0;
while (!feof($fileHandle) ) {
$line = fgetcsv($fileHandle);
if($line[0]!="") {
$data = str_replace("'", "", (nl2br ($line[0])));
$dataArray = explode('<br />' ,$data );
foreach($dataArray as $data) {
$codesArray[] = trim($data);
}
}
}
echo "<pre>";
print_r($codesArray);
