Hello I have a text which written like this:
sh222022 HALIMA 20220329 1200 -21.4 82.5 S TS 45 994
wp932022 INVEST 20220329 1200 11.1 115.7 W DB 20 1008
I try separate word each but it didnt work
<?php
// get files content
$file_investraw = file_get_contents("./cache/data.txt", FILE_IGNORE_NEW_LINES);
// put the data into arrays
$data_investraw = explode("\n", $file_investraw);
?>
I want the output like this, so how should I echo each word I like?:
sh222022
HALIMA
20220329
1200
-21.4
82.5
S
TS
45
994
or if I want to echo each word or each value, I cant separate it. Thank You
you can do that like this.
// get files content
$file_investraw = file_get_contents("./cache/data.txt", FILE_IGNORE_NEW_LINES);
// put the data into arrays and remove the empty element from array
$data_investraw = array_filter(explode("\n", $file_data));
// make the array filter data into string
$data_investraw = implode(' ',$data_investraw);
// explode the string into array
$data_investraw = array_filter(explode(" ", $data_investraw));
this way you can achieve your desired output.

I have a text file like this:
1
2
3
4
5
6
7
8
9
10
And I want to remove specific lines which numbers are in an array like this:
$myfile='txt.txt';
$remove=array(1,3,6,7,10);
//wanna remove these lines
So I tried this code but It didn't work and It just doubles the text and ruins everything:
<?php
$myfile='txt.txt';
$remove=array(1,3,5,7,10);
$lines=file($myfile);
$countline=sizeof($lines);
$data=file_get_contents($myfile);
for ($i=0; $i < $countline+1; $i++) {
if (in_array($i, $remove)) {
$editeddata=str_replace($lines[$i], "", $data);
$removeline = file_put_contents($myfile, $editeddata.PHP_EOL , FILE_APPEND | LOCK_EX);
}
}
?>
I couldn't use ((for)) properly and I think it will just ruin the text because it deletes lines one after another have been deleted and it changes the order so I should have a code to remove them all at once.
And please don't give a code to just replace numbers because the main text file is not only numbers and contains word,etc...
Thanks A lot!
You're reading the file twice (with file and file_get_contents), which I think is confusing the later code. You have everything you need with the first call - an array of all the lines in the file. You're also using str_replace to remove the content, which seems a bit dangerous if any of the content is repeated.
I'd refactor this to simply filter the array of lines based on their line-number, then write it back to the file in a single operation:
$myfile = 'txt.txt';
$remove = [1, 3, 5, 7, 10];
// Read file into memory
$lines = file($myfile);
// Filter lines based on line number (+1 because the array is zero-indexed)
$lines = array_filter($lines, function($lineNumber) use ($remove) {
return !in_array($lineNumber + 1, $remove);
}, ARRAY_FILTER_USE_KEY);
// Re-assemble the output (the lines already have a line-break at the end)
$output = implode('', $lines);
// Write back to file
file_put_contents($myfile, $output);
If the file fits in memory then you can do the simple:
$myfile='txt.txt';
$remove=array(1,3,6,7,10);
file_put_contents($myfile, implode(PHP_EOL,array_diff($file($myfile,FILE_IGNORE_NEW_LINES), $remove)));
Note: Because it's a bit ambiguous whether $remove has the content or the lines you want to remove, the above code removes the content . If you want to remove lines change array_diff($file($myfile,FILE_IGNORE_NEW_LINES), $remove) to array_diff_keys($file($myfile,FILE_IGNORE_NEW_LINES), array_flip($remove))
If your file is large then you need to resort to some sort of streaming. I suggest against reading and writing to the same file and doing something like:
$myfile='txt.txt';
$remove=array(1,3,6,7,10);
$h = fopen($myfile,"r");
$tmp = fopen($myfile.".tmp", "w");
while (($line = fgets($h)) !== false) {
if (!in_array(rtrim($line, PHP_EOL), $remove)) {
fwrite($tmp, $line);
}
}
fclose($h);
fclose($tmp);
unlink($myfile);
rename($myfile.".tmp", $myfile);
I need to transpose some values in some csv files that we get sent on a regular basis so that they are able to be imported into a website and I'm not sure the best way to go about doing it.
The data arrives in a csv file with a header row containing the column names, and the first column values are product ID's. The data looks like this…
ID F F-VF VF VF-XF XF
1 840 960 1080 1248 1944
2 1137.5 1300 1462.5 1690 2632.5
3 1225 1400 1575 1820 2835
What I'm looking to do is change this around so the column name and it's value are put into a new line for each value for the same id like so…
ID COND VALUE
1 F 840
1 F-VF 960
1 VF 1080
1 VF-XF 1248
1 XF 1944
2 F 1137.5
2 F-VF 1300
2 VF 1462.5
2 VF-XF 1690
2 XF 2835
I may also need to add some strings into the cells - is that easy to do?
Thanks a lot
Not necessarily the most elegant version, just to get an idea.
Something like this would work in case it's a existing csv, which gets read and overwritten with the transposed version.
// assuming a dataset like
// ----
// fruit, apple, pear, peach
// animal, eagle, bear, wolf
// car, renault, fiat, nio
$f = fopen($savePath, 'r');
$header = [];
$data = [];
while($row = fgetcsv($f, 0, ",")) {
$header[]=$row[0];
for ($i = 1; $i < sizeof(array_keys($row)); $i++) {
$data[$i][$row[0]]=$row[$i];
}
}
fclose($f);
$f = fopen($savePath, 'w');
fputcsv($f, $header);
foreach ($data as $recordColDataSet) {
fputcsv($f, array_values($recordColDataSet));
}
fclose($f);
Transposing arrays could also be something to look at eg in this question here:
Transposing multidimensional arrays in PHP
Have you tried any of the standard PHP methods like: str_getcsv() or fgetcsv()?
A quick search of "php csv" provides a TON of possible solutions. I suggest trying a few, then reporting back here if you have a specific problem.
I want to format the credit cards like below when i display it,
Eg:
1234 4567 9874 1222
as
1xxx xxxx xxx 1222
Is there any formatting function like this in Yii ?
No - but there's nothing wrong with using straight PHP.
If you always want the 1st and the last 4 chars you can do something like this:
$last4 = substr($cardNum, -4);
$first = substr($cardNum, 0, 1);
$output = $first.'xxx xxxx xxxx '.$last4;
There are many ways to do this, nothing Yii specific
You could do it using str_split (untested):
$string = "1234 4567 1234 456";
$character_array = str_split($string);
for ($i = 1; $i < count($character_array) - 4; $i++) {
if ($character_array[$i] != " "){
$character_array[$i] = "x";
}
}
echo implode($character_array);
So we are creating an array of characters from the string called
$character_array.
We are then looping thru the characters (starting from position 1,
not 0, so the first character is visible).
We loop until the number of entries in the array minus 4 (so the last
4 characters are not replaced) We replace each character in the loop
with an 'x' (if it's not equal to a space)
We the implode the array back into a string
And you could also use preg_replace :
$card='1234 4567 9874 1222';
$xcard = preg_replace('/^([0-9])([- 0-9]+)([0-9]{4})$/', '${1}xxx xxxx xxxx ${3}', $card);
This regex will also take care of hyphens.
There is no in-built function in Yii.
I have been reading/testing examples since last night, but the cows never came home.
I have a file with (for example) approx. 1000 characters in one line and want to split it into 10 equal parts then write back to the file.
Goal:
1. Open the file in question and read its content
2. Count up to 100 characters for example, then put a line break
3. Count 100 again and another line break, and so on till it's done.
4. Write/overwrite the file with the new split content
For example:
I want to turn this => KNMT2zSOMs4j4vXsBlb7uCjrGxgXpr
Into this:
KNMT2zSOMs
4j4vXsBlb7
uCjrGxgXpr
This is what I have so far:
<?php
$MyString = fopen('file.txt', "r");
$MyNewString;
$n = 100; // How many you want before seperation
$MyNewString = substr($MyString,0,$n);
$i = $n;
while ($i < strlen($MyString)) {
$MyNewString .= "\n"; // Seperator Character
$MyNewString .= substr($MyString,$i,$n);
$i = $i + $n;
}
file_put_contents($MyString, $MyNewString);
fclose($MyString);
?>
But that is not working quite the way I anticipated.
I realize that there are other similiar questions like mine, but they were not showing how to read a file, then write back to it.
<?php
$str = "aonoeincoieacaonoeincoieacaonoeincoieacaonoeincoieacaonoeincoieacaon";
$pieces = 10;
$ch = chunk_split($str, $pieces);
$piece = explode("\n", $ch);
foreach($piece as $line) {
// write to file
}
?>
http://php.net/manual/en/function.chunk-split.php
Hold on here. You're not giving a file name/path to file_put_contents();, you're giving a file handle.
Try this:
file_put_contents("newFileWithText.txt", $MyNewString);
You see, when doing $var=fopen();, you're giving $var a value of a handle, which is not meant to be used with file_put_contents(); as it doesnt ask for a handle, but a filename instead. So, it should be: file_put_contents("myfilenamehere.txt", "the data i want in my file here...");
Simple.
Take a look at the documentation for str_split. It will take a string and split it into chunks based on length, storing each chunk at a separate index in an array that it returns. You can then iterate over the array adding a line break after each index.
I have to convert a long string of data into values so that I can import them into my database. Unfortunately, the data is displayed as text and not XML, so I need a way to convert this into, ideally, a key->value array.
The data looks like this:
AU - Author 1
AU - Author 2
AU - Author 3
LA - ENG
PT - ARTICLE
DEP - 235234
TA - TA
JN - Journal name
JID - 3456346
EDAT- 2011-11-03 06:00
MHDA- 2011-11-03 06:00
CRDT- 2011-11-03 06:00
TI - multi-line text text text text text
text text tex tex text
text text tex tex text
After researching, it seems like explode could be a viable means to accomplish this, but I'm not sure how to implement it in this scenerio, or if there is a better method of accomplishing this. Especially since there can be random hyphens and line breaks in the middle of the string.
Any help much appreciated in advance!
Since values can contain dashes and be spread across multiple lines, I think the safest method for separating keys from values is using substr(), since the separating dashes always sit at the same character position in the string.
FIXED
<?php
// first, split into lines
$lines = explode("\n",str_replace(array("\r\n","\r"),"\n",$data));
// this will hold the parsed data
$result = array();
// This will track the current key for multi-line values
$thisKey = '';
// Loop the split data
foreach ($lines as $line) {
if (substr($line,4,1) == '-') {
// There is a separator, start a new key
$thisKey = trim(substr($line,0,4));
if ($result[$thisKey]) {
// This is a duplicate value
if (is_array($result[$thisKey])) {
// already an array
$result[$thisKey][] = trim(substr($line,5));
} else {
// convert to array
$result[$thisKey] = array($result[$thisKey],trim(substr($line,5)));
}
} else {
// Not a duplicate value
$result[$thisKey] = trim(substr($line,5));
}
} else {
// There is no separator, append data to the last key
if (is_array($result[$thisKey])) {
$result[$thisKey][count($result[$thisKey]) - 1] .= PHP_EOL.trim(substr($line,5));
} else {
$result[$thisKey] .= PHP_EOL.trim(substr($line,5));
}
}
}
print_r($result);
?>
See it working
