Hello magento,

considering that your input file is as above INPUT format and its name is text.csv.

you can try something like following

<?php
$file = fopen("test.csv", "r");
$members = array();

$x = 0;

while (!feof($file)) {
   if($x > 0)
   {
   		$line = fgets($file);
		
		$line = preg_replace('!\s+!', ' ', $line);
		
		$arr_line = explode(' ', $line);
		
		$arr_prod = explode(',',$arr_line[1]);
		
		foreach($arr_prod as $key => $val)
		{
			if(trim($val) != '' && trim($arr_line[0]) != '')
			{
				echo $arr_line[0] . " " . $val . "<br />";
			}
		}
   }
   else
   {
   		$line = fgets($file);
   		echo "ID         Product Details<br/>";
   }
   $x++;
}

fclose($file);
?>

Open in new window


Hope this will help you.

Thank you.

Dear  magento,

you can try following code  and I tested it works , extraction is starting at after line of "ID      Product Details" , and I suppose the character  between "2500" and "PRODXXX" is space, otherwise you need to find out the exact delimiter for explode() function in php  if it is not a space between them

Duncan

<?php
$proverbs=file("input.csv");$cnt=count($proverbs);$kline=array();
for ($i=1;$i<$cnt;$i++){$mline=explode(",",$proverbs[$i]);$cnt_2=count($mline);
for($a=0;$a<$cnt_2;$a++){array_push($kline,trim($mline[$a],"\n")."\n");}}
$cnt=count($kline);
for ($a=0;$a<$cnt-1;$a++){
$mline=explode(" ",$kline[$a]);$next=explode(" ",$kline[$a+1]);
//echo $next[0]."=$a=".$mline[0]."===\n";
if ($next[0]>0){} else {$kline[$a+1]=$mline[0]." ".$kline[$a+1];}
}
file_put_contents("output.csv",$kline);
?>

Hi  Duncab7,

Its a csv file  so the delimiter is comma.

I have attached the csv file to previous post .

Not sure, my xampp was not running properly and hence i cant test it. Ca you pls run it and send me the output file. That would be great !!!

Thanks

duncanb7Commented:
in my code, I already take care of delimiter of comma "," as follows
$mline=explode(",",$proverbs[$i]);

I mean just make sure the char between 25xx and PRODxxx that is space rather
than other character  for doing math comparsion.

I tested the code it works and output the exact what you want with just simple code

please see all attached file

Please try this one

<?php

$val = file($filename);

if(!empty($val))
{
   foreach($val as $key=>$value)
   {
		$csvval = explode(',',trim($value,"\n"));
// echo '<pre>';print_r($csvval);
		if(($csvval[0]=="ID") || ($csvval[0] =='Product Details'))
		{
		 continue;
		}
		else
		{
		   $idval = $csvval[0];
		   unset($csvval[0]);
		   $dataval =  $csvval;
			if(is_array($dataval))
			{
			   foreach($dataval as $datakey=>$dataval)
			   {
			      $dataval = str_replace('"'," ",$dataval);

			      $datadump[$idval][]= trim(trim($dataval),"\n");

			   } 
			}else
			{
			   $dump = trim($csvval,'"');
			   $dataprints= trim(trim($dump),"\n");

			   $datadump[$idval][] = $dump;

		}

	}

Hello magento,

did u try my code?

It should work fine for u. you will see expected output in browser window.

Also you should put your test.csv file in same directory as your php file.

How are you running the code? in browser or from command line?

are you getting any error while running the code?

Thank you.

Sorry forgot to paste the o/p.

                        $datadump[$idval][]= trim(trim($dataval),"\n");
line 26 is not required. You can run without that too.

Add back the first line of "ID PRODUCT Detail"

You input file format is different on this thread compared to the test.csv, that is
no "PROD", but it will be easier and simple

Please read the attached file

input.csv format is changed from input.csv to test.csv as you request
junk.php is changed to junk2.php

Be reminded your product detail data with " quote at start and end of second column string  such as "0,0,0,0"

Duncan

<?php
$proverbs=file("test.csv");
$cnt=count($proverbs);
$kline=array();
array_push($kline,$proverbs[0]);
for ($i=1;$i<$cnt;$i++){$mline=explode(",",$proverbs[$i]);$cnt_2=count($mline);
for($a=1;$a<$cnt_2;$a++){array_push($kline,$mline[0].",".str_replace('"',"",trim($mline[$a],"\n"))."\n");}}
