Scan special string using sscanf - php

I want for example to scan this $lang['foo1']='foo2'; from a PHP file so I tried
this but it doesn't work.
$file = "../lang/lang.en.php";
if(file_exists($file)) {
$text = fopen($file, 'r+');
$content = trim(file_get_contents($file, NULL, NULL, 221));
$i = 0;
do {
$n = sscanf($content, "\$lang['%s']=%s;", $s1[$i], $s2[$i]);
echo $s1[$i].'==>'.$s2[$i];
$i++;
} while($s1[$i]! = '' && $s2[$i] != '');
}
What is my problem?

You should just include('../lang/lang.en.php') like a normal PHP file.
Also, it's possible to make lang.en.php return an array directly with return, http://nl3.php.net/manual/en/function.return.php

I would recommend to use preg_match_all() in your case.
// Match
// $lang['PAGE_TITLE']='Meine Webseite Titel';
$content = file_get_contents('../lang/lang.en.php');
preg_match_all("~\$lang\['.+'\]\s=\s'.+';~", $content, $result);
var_dump($result);

How to fix url contains arabic characters

I want to get the url of each file in certain directory
i tried string concatenation (like: domain.folder1.folder2.file.mp3) but some folders and files is with arabic characters that make error when using the url.
example:
this is my code output:
String A :
https://linkimage2url.com/apps/quran full/محمد صديق المنشاوي/تسجيلات الإذاعة المصرية/009 - At-Taubah (The Repentance) سورة التوبة.mp3
this code is not working in some android devices
but the next code works with all devices
String B:
https://linkimage2url.com/apps/quran%20full/%D9%85%D8%AD%D9%85%D8%AF%20%D8%B5%D8%AF%D9%8A%D9%82%20%D8%A7%D9%84%D9%85%D9%86%D8%B4%D8%A7%D9%88%D9%8A/%D8%AA%D8%B3%D8%AC%D9%8A%D9%84%D8%A7%D8%AA%20%D8%A7%D9%84%D8%A5%D8%B0%D8%A7%D8%B9%D8%A9%20%D8%A7%D9%84%D9%85%D8%B5%D8%B1%D9%8A%D8%A9/009%20-%20At-Taubah%20(The%20Repentance)%20%D8%B3%D9%88%D8%B1%D8%A9%20%D8%A7%D9%84%D8%AA%D9%88%D8%A8%D8%A9.mp3
Note: i got String B from internet download manager that converts it automatically when i tried to use string A
my question is:
how to convert String A to String B by php
and is there better way to readdir and get the url of each file
My code is:
if(is_dir($parent)){
if($dh = opendir($parent)){
while(($file = readdir($dh)) != false){
if($file == "." or $file == ".."){
//...
} else { //create object with two fields
sort($file);
$fileName = pathinfo($file)['filename'];
if(is_dir($parent."/".$file)){
$data[] = array('name'=> $fileName, 'subname'=> basename($path), 'url'=> $path."/".$file, "directory"=> true);
} else {
$res = "https://linkimage2url.com".$path."/".$file;
$data[] = array('name'=> $fileName, 'subname'=> basename($path), 'url'=> $res , "directory"=> false);
}
Try this one, I've used once for a legacy project:
function encode_fullurl($url) {
$output = '';
$valid = 'ABCDEFGHIJKLMNOPQRSTUVWXYZabcdefghijklmnopqrstuvwxyz0123456789-_.~!*\'();:#&=+$,/?#[]%';
$length = strlen($url);
for ($i = 0; $i < $length; $i++) {
$character = $url[$i];
$output .= (strpos($valid, $character) === false ? rawurlencode($character) : $character);
}
return $output;
}
$url ="https://linkimage2url.com/apps/quran full/محمد صديق المنشاوي/تسجيلات الإذاعة المصرية/009 - At-Taubah (The Repentance) سورة التوبة.mp3";
echo encode_fullurl($url);
output:
https://linkimage2url.com/apps/quran%20full/%D9%85%D8%AD%D9%85%D8%AF%20%D8%B5%D8%AF%D9%8A%D9%82%20%D8%A7%D9%84%D9%85%D9%86%D8%B4%D8%A7%D9%88%D9%8A/%D8%AA%D8%B3%D8%AC%D9%8A%D9%84%D8%A7%D8%AA%20%D8%A7%D9%84%D8%A5%D8%B0%D8%A7%D8%B9%D8%A9%20%D8%A7%D9%84%D9%85%D8%B5%D8%B1%D9%8A%D8%A9/009%20-%20At-Taubah%20(The%20Repentance)%20%D8%B3%D9%88%D8%B1%D8%A9%20%D8%A7%D9%84%D8%AA%D9%88%D8%A8%D8%A9.mp3
it is not very performing, but it should do what you need
this code worked for me
thanks every one
$res1 = "https://linkimage2url.com" .$path."/".$file;
$query = flash_encode ($res1);
$url = htmlentities($query);
function flash_encode($string)
{
$string = rawurlencode($string);
$string = str_replace("%2F", "/", $string);
$string = str_replace("%3A", ":", $string);
return $string;

Search a string and delete the whole line containg the string in php

I need to search a string in .cfg file, and delete the whole line. I'm using file_get_contents to retrieve the the data in .cfg file, and I'm storing it in a variable, searching is good but not knowing how to delete the whole line?
I have a string in following way:
user $username insecure-password $password
I want to search $username and delete the whole line.
Use a little Regex to match the line:
<?php
$file = 'blah
etc
user delboy1978uk insecure-password 123456
etc
etc';
$regex = '#\nuser\s\w+\sinsecure-password\s.+\n#';
preg_match($regex, $file, $matches);
$file = str_replace($matches[0], "\n", $file);
echo $file;
Which outputs:
blah
etc
etc
etc
See it here: https://3v4l.org/BcDWK
With this method you can read each config file line by line search in each line.
$h = fopen('yourfile', 'r') ;
$match = 'username' ;
$output = [] ;
if ($h) {
while (!feof($h)) {
$line = fgets($h);
//your current search function, which search each line
if ( your_search_function($line, $match) === false) {
//array $output will not contain matching lines.
$output[] = $line;
}
}
fclose($h);
//write back to file or do something else with $output
$hw = fopen('yourfile', 'w') ;
if( $hw ) {
foreach( $output as $line ) {
fputs($hw, $line) ;
}
fclose($hw) ;
}
}

How to handle spaces with preg_split in PHP

I'm getting a ftp_rawlist of files from FTP in PHP.
I take the rawlist and run this code:
foreach ($ftp_rawlist AS $ff) {
$ff = preg_split("/[\s]+/", $ff, 9);
$perms = $ff[0];
$user = $ff[2];
$group = $ff[3];
$size = $ff[4];
$month = $ff[5];
$day = $ff[6];
$file = $ff[8];
}
This works fine, but if a $ff[8] has a space at the beginning of the file name, my code doesn't parse it to $file.
E.g. " file.pdf" is parsed as "file.pdf"
I'm not sure how to modify my preg_split to capture spaces.
Try this: Remove the + symbol from the regexp by doing:
$ff = preg_split("/[\s]/", $ff, 9);
Cheers.

Get value from file - php

Let's say I have this in my text file:
Author:MJMZ
Author URL:http://abc.co
Version: 1.0
How can I get the string "MJMZ" if I look for the string "Author"?
I already tried the solution from another question (Php get value from text file) but with no success.
The problem may be because of the strpos function. In my case, the word "Author" got two. So the strpos function can't solve my problem.
Split each line at the : using explode, then check if the prefix matches what you're searching for:
$lines = file($filename, FILE_IGNORE_NEW_LINES);
foreach($lines as $line) {
list($prefix, $data) = explode(':', $line);
if (trim($prefix) == "Author") {
echo $data;
break;
}
}
Try the following:
$file_contents = file_get_contents('myfilename.ext');
preg_match('/^Author\s*\:\s*([^\r\n]+)/', $file_contents, $matches);
$code = isset($matches[1]) && !empty($matches[1]) ? $matches[1] : 'no-code-found';
echo $code;
Now the $matches variable should contains the MJMZ.
The above, will search for the first instance of the Author:CODE_HERE in your file, and will place the CODE_HERE in the $matches variable.
More specific, the regex. will search for a string that starts with the word Author followed with an optional space \s*, followed by a semicolon character \:, followed by an optional space \s*, followed by one or more characters that it is not a new line [^\r\n]+.
If your file will have dinamically added items, then you can sort it into array.
$content = file_get_contents("myfile.txt");
$line = explode("\n", $content);
$item = new Array();
foreach($line as $l){
$var = explode(":", $l);
$value = "";
for($i=1; $i<sizeof($var); $i++){
$value .= $var[$i];
}
$item[$var[0]] = $value;
}
// Now you can access every single item with his name:
print $item["Author"];
The for loop inside the foreach loop is needed, so you can have multiple ":" in your list. The program will separate name from value at the first ":"
First take lines from file, convert to array then call them by their keys.
$handle = fopen("file.txt", "r");
if ($handle) {
while (($line = fgets($handle)) !== false) {
$pieces = explode(":", $line);
$array[$pieces[0]] = $pieces[1];
}
} else {
// error opening the file.
}
fclose($handle);
echo $array['Author'];

Function for each subfolder in PHP

I am new in PHP and can't figure out how to do this:
$link = 'http://www.domainname.com/folder1/folder2/folder3/folder4';
$domain_and_slash = http://www.domainname.com . '/';
$address_without_site_url = str_replace($domain_and_slash, '', $link);
foreach ($folder_adress) {
// function here for example
echo $folder_adress;
}
I can't figure out how to get the $folder_adress.
In the case above I want the function to echo these four:
folder1
folder1/folder2
folder1/folder2/folder3
folder1/folder2/folder3/folder4
The $link will have different amount of subfolders...
This gets you there. Some things you might explore more: explode, parse_url, trim. Taking a look at the docs of there functions gets you a better understanding how to handle url's and how the code below works.
$link = 'http://www.domainname.com/folder1/folder2/folder3/folder4';
$parts = parse_url($link);
$pathParts = explode('/', trim($parts['path'], '/'));
$buffer = "";
foreach ($pathParts as $part) {
$buffer .= $part.'/';
echo $buffer . PHP_EOL;
}
/*
Output:
folder1/
folder1/folder2/
folder1/folder2/folder3/
folder1/folder2/folder3/folder4/
*/
You should have a look on explode() function
array explode ( string $delimiter , string $string [, int $limit ] )
Returns an array of strings, each of
which is a substring of string formed
by splitting it on boundaries formed
by the string delimiter.
Use / as the delimiter.
This is what you are looking for:
$link = 'http://www.domainname.com/folder1/folder2/folder3/folder4';
$domain_and_slash = 'http://www.domainname.com' . '/';
$address_without_site_url = str_replace($domain_and_slash, '', $link);
// this splits the string into an array
$address_without_site_url_array = explode('/', $address_without_site_url);
$folder_adress = '';
// now we loop through the array we have and append each item to the string $folder_adress
foreach ($address_without_site_url_array as $item) {
// function here for example
$folder_adress .= $item.'/';
echo $folder_adress;
}
Hope that helps.
Try this:
$parts = explode("/", "folder1/folder2/folder3/folder4");
$base = "";
for($i=0;$i<count($parts);$i++){
$base .= ($base ? "/" : "") . $parts[$i];
echo $base . "<br/>";
}
I would use preg_match() for regular expression method:
$m = preg_match('%http://([.+?])/([.+?])/([.+?])/([.+?])/([.+?])/?%',$link)
// $m[1]: domain.ext
// $m[2]: folder1
// $m[3]: folder2
// $m[4]: folder3
// $m[5]: folder4
1) List approach: use split to get an array of folders, then concatenate them in a loop.
2) String approach: use strpos with an offset parameter which changes from 0 to 1 + last position where a slash was found, then use substr to extract the part of the folder string.
EDIT:
<?php
$folders = 'folder1/folder2/folder3/folder4';
function fn($folder) {
echo $folder, "\n";
}
echo "\narray approach\n";
$folder_array = split('/', $folders);
foreach ($folder_array as $folder) {
if ($result != '')
$result .= '/';
$result .= $folder;
fn($result);
}
echo "\nstring approach\n";
$pos = 0;
while ($pos = strpos($folders, '/', $pos)) {
fn(substr($folders, 0, $pos++));
}
fn($folders);
?>
If I had time, I could do a cleaner job. But this works and gets across come ideas: http://codepad.org/ITJVCccT
Use parse_url, trim, explode, array_pop, and implode
