merge 2 text files line by line into 1

I need php code example to merge 2 txt files into 1 txt file.

Example: Take the contents from file1.txt and merge with the contents of file2.txt

file1.txt
toy guns|867|6984
rolling stones|1502|12100
black blazer|12|97
laser|1726|13904
boat motor|315|2538


file2.txt
45800000|25800|black paint
403000000|44800|big ball
331000000|2654|gold money
167000000|4432|secret
192000000|53454|planet green

Merging the content of both txt files should look like this.

merge.txt
toy guns|867|6984|45800000|25800|black paint
rolling stones|1502|12100|403000000|44800|big ball
black blazer|12|97|331000000|2654|gold money
laser|1726|13904|167000000|4432|secret
boat motor|315|2538|192000000|53454|planet green

 

Try this:

$content= array();
$fp = fopen( 'file1.txt', 'r' );
while( !feof($fp) ) {
$buffer = fgets($fp,4096);
$content[] = $buffer;
}
fclose($fp);




$content2= array();
$fp = fopen( 'file2.txt', 'r' );
while( !feof($fp) ) {
$buffer = fgets($fp,4096);
$content2[] = $buffer;
}
fclose($fp);

$fp= fopen('merge.txt','w'); fclose($fp);
$fp= fopen('merge.txt','a');
foreach($content as $k=>$kk){
$a= $content[$k]. "|". $content2[$k]."\r\n";
fwrite($fp,$a);
}
fclose($fp);

 

I was looking for something similar myself.

Can you explain why you need the line '$fp= fopen('merge.txt','w'); fclose($fp);' as it seems to just open and close a file without doing anything.

 

I worked but has a bug. When using JEET's code to merged the 2 txt files it merged like this. Only the last line was formated correctly

toy guns|867|6984
|45800000|25800|black paint

rolling stones|1502|12100
|403000000|44800|big ball

black blazer|12|97
|331000000|2654|gold money

laser|1726|13904
|167000000|4432|secret

boat motor|315|2538|192000000|53454|planet green

 

Delete this part from the script: ."\r\n"

 

I found another way of merging 2 txt files line by line into 1 txt file

<?php

$a = file('file1.txt');
$b = file('file2.txt');
$c = array();
foreach($a as $k=>$v) $c[]= trim($v).'|'.trim($b[$k]);
$fp = fopen('merge.txt', 'w+'); fwrite($fp, join("\r\n", $c)); fclose($fp);

?>
