Here is my source
$Message = $_GET["message"];
$Username = htmlspecialchars($_GET["username"]);
$unix = ($_GET["time"]);
include 'mcheck.php';
$file1 = file_get_contents('filter.txt');
$bad_words = explode(PHP_EOL, $file1);
$compare = explode('', $Message);
foreach ($bad_words as $bad_word)
$Message = preg_replace('/\b('.$bad_word.')\b/i', "***", $Message);
echo $Message;
Say the bad word is go
and $Message = I Like to go to school
I want it to echo I Like to *** to school
but instead im getting
***I***Like***To******to***school***
i dont know what the problem is
Based on the output, you likely have an empty element in your array. So it's ultimately matching a word boundary (\b).
To confirm this add the following to debug your code:
$bad_words = explode(PHP_EOL, $file1);
print_r($bad_words);
As an aside, it's a waste to loop over each bad word. I suggest using a single regex with alterations once you've resolved the above.
For example:
\b(one|two|three)\b
Why don't you just use str_replace
Example
$badWords = array("go","school");
$message = " I like to go to school" ;
$newMessage = str_replace($badWords, "***", $message);
echo $newMessage ;
Output
I like to *** to ***
Your file most likely ends with a newline (which is a good thing: all text-files on *nix systems are supposed to), which means that the last element of explode(PHP_EOL, $file1) is empty (it's everything between the last newline and the end of the file, which is nothing). I would recommend writing:
$file1 = trim(file_get_contents('filter.txt'));
using the trim function to eliminate that last newline.
i think yo need to remove empty fields from explode resulting array
You should use strtr for this purpose.
you can pass array with key=>replace, which will be somewhat more efficient that preg_replace
apart from that, must be bad badwords dic.

How can I get the 800-555 from this 800-555-5555 with explode()?
Here is a good example:
$rawPhoneNumber = "800-555-5555";
$phoneChunks = explode("-", $rawPhoneNumber);
First chunk = $phoneChunks[0]; //800
Second chunk = $phoneChunks[1]; //555
Third Chunk chunk = $phoneChunks[2]; //5555
But how can I get the 800-555?
Okay, I see, here need more comment... So, this is only an example... In real I add a word (now $word) to string delimiter and my string is a full article... I want that, if this word second time published in the article, with str_word_count() will count, how many characters was in the text to the second (or third, if I want that) $word...
So I want that, I get the string from the second "hit" to back.
Okay, here is a more obvious example:
$text = oh my god, thank you the lot of downvotes, geniuses *.*
$explode = explode(",", $text);
$whatiwant = $explode?? // I WANT THE STRING FROM THE SECOND "," TO BACK
So I want that $whatiwant = oh my god, thank you the lot of downvotes
Implode, explode and array_slice.
I use array_slice because that makes the function more dynamic.
Now you can just set the $items to get the number of items you want.
If you set a negative value it counts backwards.
$delim = ",";
$items =2;
$text = "oh my god, thank you the lot of downvotes, geniuses *.*";
$whatiwant = implode($delim, array_slice(explode($delim, $text),0,$items));
Echo $whatiwant;

You could also have an start variable to make the start position dynamic.

Doing concatenation of already generated array's indexes is the simple way for you.
Sample Code
echo $phoneChunks[0]."-".$phoneChunks[1];
This is working for me:
$rawPhoneNumber = "800-555-5555";
$phoneChunks = explode("-", $rawPhoneNumber);
$first_chunk = $phoneChunks[0]; //800
$second_chunk = $phoneChunks[1]; //555
$third_chunk_chunk = $phoneChunks[2]; //5555
$portion_array = array($first_chunk, $second_chunk);
echo implode("-",$portion_array);
Output:
800-555
I want to update a file name so that it looks like this each time it is updated.
some_name_1, some_name_2, some_name_3, etc.
Each update will increase the trailing integer by one. Below is my prototype, I wanted to make sure this is the best practice way to do it, before implementing it. Also, I'm not 100% PHP will do the implicit casting correctly.
Is this a good practice way to update a file name?
// ... in a class
private function updateFileName()
{
$pattern = '#_(\d+)$#';
$subject = $this->file_name; // $subject holds current file name
preg_match($pattern, $subject, $matches);
if($matches[0])
{
$patterns = array();
$temp = $matches[0];
$patterns[0] = '/$temp$/';
$replacements = array();
$replacements[0] = $matches[0] + 1;
preg_replace($patterns, $replacements, $subject); // $subject now holds new name
}
}
Clarification
The file name is actually a hash, and is one string of characters.
The _1, etc will always be at the end of the string ( perhaps good to use an anchor )
You can do the whole thing in one preg_replace:
preg_replace("/\b([^\w]+)\b/i",'_',$filename);
I am not the best with RegEx... I have some PHP code:
$pattern = '/activeAds = \[(.*?)\]/si';
$modData = preg_replace($pattern,'TEST',$data);
So I have a JavaScript file, and it declares and array:
var activeAds = [];
I need this to populate the array with my string, or if the array already has a string inside it, i want to replace it with my string (in this case "TEST").
Right now, my REGEX is replacing everything, including my start and end, i need to only replace whats between.
I'm left with:
var TEST;
TIA
You could capture what's before and what's after the part you want replacing:
$pattern = '/(activeAds = \[).*?(\])/si';
After capturing these parts, you can keep them and replace the part in the middle:
$modData = preg_replace($pattern, '\1TEST\2', $data);
There are many ways you could do this, mine is below:
$data = array("activeAds = testing123");
$pattern = "/activeAds\s?=\s?(.*)/";
$result = preg_replace($pattern,"activeAds = TEST", $data);
var_dump($result);
Edit: Forgot to mention that the \s? here allow for an optional space.
This is my first post on the internet for some assistance with coding so please bear with me!
I have been finding open code on the internet for a few years and modding it to do what I want but I seem to have come up against a wall with this one that I am sure is very simple. If you would please be able to help me it would be very much appreciated.
I have the following page:
<?php
$text = $_REQUEST['message'];
$f = file_get_contents("all.txt");
$f = explode(", ", $f);
function modFile($pos, $tothis, $inthis)
{
foreach($inthis as $pos => $a){
}
$newarr = implode("\r\n", $inthis);
$fh = fopen("example.txt", "w");
fwrite($fh, $newarr);
fclose($fh);
}
modFile(4, '', $f);
I have a file (all.txt) with the following:
11111111111, 22222222222, 33333333333, 44444444444
That I wish to display like this:
11111111111
22222222222
33333333333
44444444444
and to add a space then some text after each number where the text is the same on each line:
11111111111 text here
22222222222 text here
33333333333 text here
44444444444 text here
I have an html form that passes the custom text to be appended to each line.
I need to keep the file all.txt intact then save the newly formatted file with a different name.
I have tried putting variables into the implode where I currently have the "\r\n" but this does not work.
Any help very much appreciated.
Thanks in advance!
A few notes about your code: You are passing $pos to the function but it will get overwritten in the foreach. Also the foreach is empty, so what's it good for? And I don't see you use $text anywhere either.
To achieve your desired output, try this instead:
file_put_contents(
'/path/to/new.txt',
preg_replace(
'/[^\d+]+/',
' some text' . PHP_EOL,
file_get_contents('all.txt')
)
);
The pattern [^\d+]+ will match any string that is not a consecutive number and replace it with "some text " and a new line.
A somewhat more complicated version achieving the same would be:
file_put_contents(
'/path/to/new.txt',
implode(PHP_EOL, array_map(
function ($number) {
$message = filter_var(
$_POST['message'], FILTER_SANITIZE_SPECIAL_CHARS
);
return sprintf('%s %s', trim($number), $message);
},
array_filter(str_getcsv(file_get_contents('/path/to/all.txt')))
)
));
This will (from the inside out):
Load the content of all.txt and parse it as CSV string into an array. Each array element corresponds to a number.
Each of these numbers is appended with the message content from the POST superglobal (you dont want to use REQUEST).
The resulting array is then concatenated back into a single string where the concatenating character is a newline.
The resulting string is written to the new file.
In case the above is too hard to follow, here is a version using temp vars and no lambda:
$allTxtContent = file_get_contents('/path/to/all.txt');
$numbers = array_filter(str_getcsv($allTxtContent));
$message = filter_var($_POST['message'], FILTER_SANITIZE_SPECIAL_CHARS);
$numbersWithMessage = array();
foreach ($numbers as $number) {
$numbersWithMessage[] = sprintf('%s %s', trim($number), $message);
};
$newString = implode(PHP_EOL, $numbersWithMessage);
file_put_contents('/path/to/new.txt', $newString);
It does the same thing.
Your foreach() closing brace is on the wrong place. You've missed the exact part of running the execution of the new file creation. Here:
$text = $_REQUEST['message'];
$f = file_get_contents("all.txt");
$f = explode(", ", $f);
function modFile($pos, $tothis, $inthis, $text){
$fh = fopen("example.txt", "w");
foreach($inthis as $pos => $a){
$newarr = $a." ".$text."\r\n";
fwrite($fh, $newarr);
}
fclose($fh);
}
modFile(4, "", $f, $text);
This is for formatting your new file as you desire, however, you're not passing the new $text['message'] you want to append to your new file. You could either modify your mod_file() method or pass it within the foreach() loop while it runs.
EDIT* Just updated the whole code, should be now what you aimed for. If it does, please mark the answer as accepted.
I have some text inside $content var, like this:
$content = $page_data->post_content;
I need to slice the content somehow and extract the sentences, inserting each one inside it's own var.
Something like this:
$sentence1 = 'first sentence of the text';
$sentence2 = 'second sentence of the text';
and so on...
How can I do this?
PS
I am thinking of something like this, but I need somekind of loop for each sentence:
$match = null;
preg_match('/(.*?[?\.!]{1,3})/', $content, $match);
$sentence1 = $match[1];
$sentence2 = $match[2];
Ty:)
Do you need them in variables? Can't you use a array?
$sentence = explode(". ", $page_data->post_content);
EDIT:
If you need variables:
$allSentence = explode(". ", $page_data->post_content);
foreach($allSentence as $key => $val)
{
${"sentence". $key} = $val;
}
Assuming each sentence ends with full stop, you can use explode:
$content = $page_data->post_content;
$sentences = explode('.', $content);
Now your sentences can be accessed like:
echo $sentences[0]; // 1st sentence
echo $sentences[1]; // 2nd sentence
echo $sentences[2]; // 3rd sentence
// and so on
Note that you can count total sentences using count or sizeof:
echo count($sentences);
It is not a good idea to create a new variable for each sentence, imagine you might have long piece of text which would require to create that number of variables there by increasing memory usage. You can simply use array index $sentences[0], $sentences[1] and so on.
Assuming a sentence is delimited by terminating punctuation, optionally followed by a space, you can do the following to get the sentences in an array.
$sentences = preg_split('/[!?\.]\s?/', $content);
You may want to trim any additional spaces as well with
$sentences = array_map('trim', $sentences);
This way, $sentences[0] is the first, $sentences[1] is the second and so on. If you need to loop through them you can use foreach:
foreach($sentences as $sentence) {
// Do something with $sentence...
}
Don't use individually named variables like $sentence1, $sentence2 etc. Use an array.
$sentences = explode('.', $page_data->post_content);
This gives you an array of the "sentences" in the variable $page_data->post_content, where "sentences" really means sequences of characters between full stops. This logic will get tripped up wherever a full stop is used to mean something other than the end of a sentence (e.g. "Mr. Watson").
Edit: Of course, you can use more sophisticated logic to detect sentence boundaries, as you have suggested. You should still use an array, not create an unknown number of variables with numbers on the ends of their names.
