I have server output that looks like this
PLAYER_ENTERED name ipaddress username
If the string contains PLAYER_ENTERED there will always be 3 spaces within the string separating it (how can this be modified so it does this too?). I would like to print out only the ipaddress and username (last 2 sections).
How can this be done?
This is code that prints out the whole thing:
$q = $_REQUEST["ipladder"];
$f = fopen("ladderlog.txt", "r");
while (($line = fgets($f)) !== FALSE)
{
if (strstr($line, $q))
{
print "<li>$line";
}
I imagine this using explode() but I've given up trying since I hardily know how to code php.
Desired Output
username ipaddress
$q = $_REQUEST["ipladder"];
$f = fopen("ladderlog.txt", "r");
while (($line = fgets($f)) !== FALSE)
{
if (strstr($line, $q))
{
$data = explode(" ", $line); // split using the space into an array
// array index 0 = PLAYER_ENTERED
print "IP:" . $data[1]; // array index 1 = IP
print "Name: " . $data[2]; // array index 2 = name
}
}
You can use substr()to check if the first 14 characters of $line equals PLAYER_ENTERED and then you use list() and explode() to extract the data from the line.
$q = $_REQUEST["ipladder"];
$f = fopen("ladderlog.txt", "r");
while(($line = fgets($f)) !== FALSE)
{
if(substr($line, 0, 14) == 'PLAYER_ENTERED'){
list($event, $name, $ip, $username) = explode($string); // here they come!
echo 'Name: ' . $name . ', ip: ' . $ip . ', username: ' . $username;
}
}
try this ...
<?
$str = "PLAYER_ENTERED name 108.21.131.56 username";
if ( preg_match( "~^(.+)\s+(.+)\s+([\d\.]+)\s+(.+)$~msi", $str, $vv ))
echo $vv[3] . " and " .$vv[4] ;
else "N/A";
?>
IMHO Perl regexp - is the right Way to parse strings ...
One way would be:
$tokens = explode(' ', $line);
if (count($tokens) == 4 && $tokens[2] == $q) {
printf('IP: %s Username: %s', $tokens[2], $tokens[3]);
}
<?php
$str = 'PLAYER_ENTERED name 108.21.131.56 username';
$data = explode(" ", $str )
print_r($data)
?>

My string is : Hi my, name is abc
I would like to output "Hi Name".
[Basically first word of comma separated sentences].
However sometimes my sentence can also be Hi my, "name is, abc"
[If the sentence itself has a comma then the sentence is enclosed with ""].
My output in this case should also be "Hi Name".
So Far I've done this
$str = "hi my,name is abc";
$result = explode(',',$str); //parsing with , as delimiter
foreach ($result as $results) {
$x = explode(' ',$results); // parsing with " " as delimiter
forach($x as $y){}
}
You can use explode to achieve YOUR RESULT and for IGINORE ' OR " use trim
$str = 'hi my,"name is abc"';
$result = explode(',',$str); //parsing with , as delimiter
$first = explode(' ',$result[0]);
$first = $first[0];
$second = explode(' ',$result[1]);
$second = trim($second[0],"'\"");
$op = $first." ".$second;
echo ucwords($op);
EDIT or if you want it for all , separated values use foreach
$str = 'hi my,"name is abc"';
$result = explode(',',$str); //parsing with , as delimiter
$op = "";
foreach($result as $value)
{
$tmp = explode(' ',$value);
$op .= trim($tmp[0],"'\"")." ";
}
$op = rtrim($op);
echo ucwords($op);
Basically it's hard to resolve this issue using explode, str_pos, etc. In this case you should use state machine approach.
<?php
function getFirstWords($str)
{
$state = '';
$parts = [];
$buf = '';
for ($i = 0; $i < strlen($str); $i++) {
$char = $str[$i];
if ($char == '"') {
$state = $state == '' ? '"' : '';
continue;
}
if ($state == '' && $char == ',') {
$_ = explode(' ', trim($buf));
$parts[] = ucfirst(reset($_));
$buf = '';
continue;
}
$buf .= $char;
}
if ($buf != '') {
$_ = explode(' ', trim($buf));
$parts[] = ucfirst(reset($_));
}
return implode(' ', $parts);
}
foreach (['Hi my, "name is, abc"', 'Hi my, name is abc'] as $str) {
echo getFirstWords($str), PHP_EOL;
}
It will output Hi Name twice

$file_handle = fopen("./news.txt", "rb");
while (!feof($file_handle) ) {
$line_of_text = fgets($file_handle);
$parts = explode(',', $line_of_text);
print $parts[0] . $parts[1] . $parts[2];
}
fclose($file_handle);
This would work and would also stop reading as soon as it found the right line (unlike the other answers who read the whole no file matter what)
if (isset($_GET['row']))
{
$file_handle = fopen("./news.txt", "rb");
$i = 0;
while (!feof($file_handle))
{
if ($i == $_GET['row'])
{
$line_of_text = fgets($file_handle);
$parts = explode(',', $line_of_text);
print $parts[0] . $parts[1] . $parts[2];
break;
}
$i++;
}
fclose($file_handle);
}
You first have to explode by rule with explode("/n", $txt) than you've an array of each rule. After you stored this explode in to a variable than you should explode a specific value again by ,.
A straightforward way to do this: if record number 2 is always on line number 3.
if (!isset($_GET['row']) || !is_int($_GET['row'])) {
echo "please supply a row number";
die;
}
$lines = file('news.txt');
// assumes record number 2 is on line 3
$row = $_GET['row'] + 1;
$parts = explode(',', $lines[$row]);
print $parts[0] . $parts[1] . $parts[2];
If record number 2 is not guaranteed to be on line 3
$row = $_GET['row'];
foreach ($lines as $line) {
if (strpos($line, $row) === 0) {
$parts = explode(',', $lines[$row]);
print $parts[0] . $parts[1] . $parts[2];
break;
}
}
If the file is extremely large you will want to read line by line from a buffer.
$row = $_GET['row'];
if ($fp = fopen('news.txt', 'r')) {
while ($line = fgets($fp)) {
if (strpos($line, $row) === 0) {
$parts = explode(',', $line);
print $parts[0] . $parts[1] . $parts[2];
break;
}
}
fclose($fp);
}
I need a PHP script to print customer names in a file. There's hundreds of names and addresses but I want to print only the names with a maximum of 15 letters.
<?php
$file = file_get_contents('data-cust.txt');
$keyword = 'name';
$str = substr($file, strpos($file, $keyword) + strlen($keyword), 15);
echo $str;
?>
I tried using the above but only printed one name. How do I make it print all names?
Thanks.
If the names are on their own line, something like this should work.
<?php
$file = file('data-cust.txt');
foreach($file as $line) {
$keyword = 'name';
$str = substr($line, strpos($line, $keyword) + strlen($keyword), 15);
echo $str;
}
You need to open the file and read it then extract the names.
$file = fopen("data-cust.txt", "r");
$keyword = 'name';
$str = array() ;
if ($file) {
while (($line = fgets($file )) !== false) {
$name = substr($line, strpos($line, $keyword) + strlen($line), 15);
echo $name ;
$str[] = $name ;
}
} else {
// error opening file
}
fclose($file );
print_r($str) ;
I'm new at PHP so I'm need help to build this script.
I have a file.txt file with following lines:
aaaa 1234
bbba 1234
aaaa 1236
cccc 1234
aaaa 1238
dddd 1234
I want to find the line with string "aaaa" and print:
String "aaaa" found 3 times at lines: 1, 3, 5.
And better it can print these lines.
I tried this code:
<?
function find_line_number_by_string($filename, $search, $case_sensitive=false ) {
$line_number = '';
if ($file_handler = fopen($filename, "r")) {
$i = 0;
while ($line = fgets($file_handler)) {
$i++;
//case sensitive is false by default
if($case_sensitive == false) {
$search = strtolower($search); //convert file and search string
$line = strtolower($line); //to lowercase
}
//find the string and store it in an array
if(strpos($line, $search) !== false){
$line_number .= $i.",";
}
}
fclose($file_handler);
}else{
return "File not exists, Please check the file path or filename";
}
//if no match found
if(count($line_number)){
return substr($line_number, 0, -1);
}else{
return "No match found";
}
}
$output = find_line_number_by_string('file.txt', 'aaaa');
print "String(s) found in ".$output;
?>
But I dont know how to count total of strings found (3) and print each found line.
Thank in advance.
There are lots of ways to do this that produce the same final result but differ in the specifics.
Assuming that your input is not large enough that you are concerned about loading it in memory all at once, one of the most convenient approaches is to use file to read the file's contents into an array of lines, then preg_grep to filter the array and only keep the matching lines. The resulting array's keys will be line numbers and the values will be whole lines that matched, perfectly fitting your requirements.
Example:
$lines = file('file.txt');
$matches = preg_grep('/aaaa/', $lines);
echo count($matches)." matches found.\n";
foreach ($matches as $line => $contents) {
echo "Line ".($line + 1).": ".$contents."\n";
}
$str = "aaaa";
$handle = fopen("your_file.txt", "r");
if ($handle) {
echo "String '".$str."' found at lines : ";
$count = 0;
$arr_lines = array();
while (($line = fgets($handle)) !== false) {
$count+=1;
if (strpos($line, $str) !== false) {
$arr_lines[] = $count;
}
}
echo implode(", ", $arr_lines).".";
}
UPDATE 2 :
$file = "your_file.txt";
$str = "aaaa;";
$arr = count_line_no($file, $str);
if(count($arr)>0)
{
echo "String '".$str."' found at lines : ".implode(", ", $arr).".";;
}
else
{
echo "String '".$str."' not found in file ";
}
function count_line_no($file, $str)
{
$arr_lines = array();
$handle = fopen("your_file.txt", "r");
if ($handle) {
$count = 0;
$arr_lines = array();
while (($line = fgets($handle)) !== false) {
$count+=1;
if (strpos($line, $str) !== false) {
$arr_lines[] = $count;
}
}
}
return $arr_lines;
}
**Try it for solve your problam **
if(file_exists("file.txt")) // check file is exists
{
$f = fopen("file.txt", "r");
// Read line by line until end of file
$row_count = 0;
while(!feof($f))
{
$row_count += 1;
$row_data = fgets($f);
$findme = 'aaaa';
$pos = strpos($row_data, $findme);
if ($pos !== false)
{
echo "The string '$findme' was found in the string '$row_data'";
echo "<br> and line number is".$row_data;
}
else
{
echo "The string '$findme' was not found ";
}
}
fclose($f);
}
I have a .txt file that has the following details:
ID^NAME^DESCRIPTION^IMAGES
123^test^Some text goes here^image_1.jpg,image_2.jpg
133^hello^some other test^image_3456.jpg,image_89.jpg
What I'd like to do, is parse this ad get the values into a more readable format, possibly into an array if possible.
Thanks
You can do that easily this way
$txt_file = file_get_contents('path/to/file.txt');
$rows = explode("\n", $txt_file);
array_shift($rows);
foreach($rows as $row => $data)
{
//get row data
$row_data = explode('^', $data);
$info[$row]['id'] = $row_data[0];
$info[$row]['name'] = $row_data[1];
$info[$row]['description'] = $row_data[2];
$info[$row]['images'] = $row_data[3];
//display data
echo 'Row ' . $row . ' ID: ' . $info[$row]['id'] . '<br />';
echo 'Row ' . $row . ' NAME: ' . $info[$row]['name'] . '<br />';
echo 'Row ' . $row . ' DESCRIPTION: ' . $info[$row]['description'] . '<br />';
echo 'Row ' . $row . ' IMAGES:<br />';
//display images
$row_images = explode(',', $info[$row]['images']);
foreach($row_images as $row_image)
{
echo ' - ' . $row_image . '<br />';
}
echo '<br />';
}
First you open the text file using the function file_get_contents() and then you cut the string on the newline characters using the function explode(). This way you will obtain an array with all rows seperated. Then with the function array_shift() you can remove the first row, as it is the header.
After obtaining the rows, you can loop through the array and put all information in a new array called $info. You will then be able to obtain information per row, starting at row zero. So for example $info[0]['description'] would be Some text goes here.
If you want to put the images in an array too, you could use explode() too. Just use this for the first row: $first_row_images = explode(',', $info[0]['images']);
Use explode() or fgetcsv():
$values = explode('^', $string);
Or, if you want something nicer:
$data = array();
$firstLine = true;
foreach(explode("\n", $string) as $line) {
if($firstLine) { $firstLine = false; continue; } // skip first line
$row = explode('^', $line);
$data[] = array(
'id' => (int)$row[0],
'name' => $row[1],
'description' => $row[2],
'images' => explode(',', $row[3])
);
}
By far the best and simplest example of this I have come accross is quite simply the file() method.
$array = file("myfile");
foreach($array as $line)
{
echo $line;
}
This will display all the lines in the file, this is also applicable for a remote URL.
Simple and clear.
REF : IBM PHP Parse
I would like to contribute a file that provides atomic data structures.
$lines = file('some.txt');
$keys = explode('^', array_shift($lines));
$results = array_map(
function($x) use ($keys){
return array_combine($keys, explode('^', trim($x)));
},
$lines
);
Try fgetcsv() with ^ as the separator character:
$file = fopen($txt_file,"r");
print_r(fgetcsv($file, '^'));
fclose($file);
http://www.w3schools.com/php/func_filesystem_fgetcsv.asp
<?php
$row = 1;
if (($handle = fopen("test.txt", "r")) !== FALSE) {
while (($data = fgetcsv($handle, 1000, "^")) !== FALSE) {
$num = count($data);
echo "<p> $num fields in line $row: <br /></p>\n";
$row++;
for ($c=0; $c < $num; $c++) {
echo $data[$c] . "<br />\n";
}
}
fclose($handle);
}
?>
Ok, didn't see the edited version, so here's a redo. It's most likely a CSV file that uses carets as the separator, so...
$fh = fopen('yourfile.txt');
$headers = fgetcsv($fh, 0, '^');
$details = array();
while($line = fgetcsv($fh, 0, '^')) {
$details[] = $line;
}
fclose($fh);
youse a list, and split the "image_1.jpg,image_2.jpg" after you explode the string:
list($number, $status, $text, $images) = explode("^", $data);
$splited_images= preg_split(',', $images);
My solution
function parseTextFile($file){
if( !$file = file_get_contents($file))
throw new Exception('No file was found!!');
$data = [];
$firstLine = true;
foreach(explode("\n", $file) as $line) {
if($firstLine) {
$keys=explode('^', $line);
$firstLine = false;
continue;
} // skip first line
$texts = explode('^', $line);
$data[] = array_combine($keys,$texts);
}
return $data;
}
