Adding columns in out file using php - php

Question

I have created a file file1.out and I am entering data to it.
$parameters is an array containing the parameters name
foreach($parameters as $name)
{
fwrite(file1.out,$name);
//here I am fetching the value of the parameter $name from database
while($row=mysql_fetch_array($result))
{
//getting some values and writing into the file;
}
}
/* this is giving output as
parameter1
1
parameter2
2
parameter3
3
but I want in this way
parameter1 parameter2 parameter3
1 2 3 */
Which special character needs to be written in the file to get a new column after fetching the data of a particular parameter? Please help.

Answer 1

You go to next line in every loop. So store them into a variable and write them to file after foreach
Use something like this:
<?php
$myfile = fopen("sample.txt", "w");
$names = '';
$values = '';
foreach($parameters as $name) {
//fwrite(file1.out,$name);
$names .= "$name \t";
//here I am fetching the value of the parameter $name from database
while($row=mysql_fetch_array($result)) {
$values .= $row[0] . "\t";
//getting some values and writing into the file;
}
}
//Make sure to remove any \n.
$values= str_replace("\n", '', $values);
$names = str_replace("\n", '', $names );
fwrite($myfile, $names . "\n" . $values);
fclose($myfile);

Use 2 varaibles inside the loop to build your strings and use "\t" between text to tab index them :
$param = ''; $vals = '';
foreach($parameters as $name)
{
$param .= '\t\tparameter1\t\t';
$vals .= '\t\t\t' . $name . '\t\t\t';
......
}
Then write $param and $vals to the file after the for loop. You can use any number of \t until you find the suitable presentation.
