[SOLVED] Writing Files

[RabPHP]

Greetings all,

 

I have to write a file format that requires some very specific data in specific positions on specific lines.

 

For example...

 

I have a list of data with the following requirements:

 

First Name (Line 1 position 1)

Last Name (Line 1 position 45)

Street Address (Line 2 Position 1)

City (Line 2 position 40)

State (Line 2 position 55)

Zip (Line 2 Position 58)

Phone Number (Line 3 Position 1)

Fax Number (Line 3 Position 11)

 

I have tried a combination of fputs, fseek however fseek keeps going back to the first line.  This will be a new file each time therefore the lines do not exist yet to put into an array.

 

Any advise greatly appreciated.

Do something like this, then write out line by line...

$1 = $fname;
$1 = str_pad($1, 44);
$1 .= $lname;

$2 = $street;
$2 = str_pad($2, 39);
$2 .= $city;
$2 = str_pad($2, 54);
$2 .= $state;
$2 = str_pad($2, 57);
$2 .= $zip;


$3 = $tel;
$3 = str_pad($3, 10);
$3 .= $fax;

 

However what would happen if I lived here 'Llandrindod Wells'?

Try

 

<?php
$formated = sprintf("%-44.44s", $firstname)."$lastname\n";
$formated .= sprintf("%-39.39s", $street).sprintf("%-15.15s", $city).sprintf("%-3.3s", $state)."$zip\n";
$formated .= sprintf("%-10.10s", $phone)."$fax\n";
?>

 

This will truncate any variable length longer than allowed.

If you have multiple lists then you could use this:

<?php

$format = array( array(45, 20),
                 array(40, 15, 3, 6),
                 array(11, 12) );

function getLineData($linedata, $line)
{
    global $format;

    $i = 0;
    foreach($format[$line] as $k => $offset)
    {
        $tmp[] = trim(substr($linedata, $i, $offset));
        $i += $offset;
    }

    return implode("\n", $tmp);
}

$data = file('details.txt');
$tmp = null;

for($i = 0; $i <= (count($data)-1); $i++)
{
    for($k = 0; $k < 3; $k++)
    {
        $tmp .= "\n" . getLineData($data[$i++], $k);
    }

    $details[] = $tmp; $tmp = null; $i--;
}

foreach($details as $c_details)
{
    list(,$firstnane, $lastname, $addr, $city, $state, $zip, $phone, $fax) = explode("\n", $c_details);

    echo "$firstnane $lastname<br />
$addr<br />
$city<br />
$state $zip<br />
$phone $fax
<hr />\n";
}

?>

 

details.txt format:

First Name1                                  Last Name1
Street Address1                         City           ST Zip
Phone #5   Fax Number1
First Name2                                  Last Name2
Street Address4                         City           ST Zip
Phone #4   Fax Number2
First Name3                                   Last Name3
Street Address3                         City           ST Zip
Phone #3   Fax Number3

Try

 

<?php
$formated = sprintf("%-44.44s", $firstname)."$lastname\n";
$formated .= sprintf("%-39.39s", $street).sprintf("%-15.15s", $city).sprintf("%-3.3s", $state)."$zip\n";
$formated .= sprintf("%-10.10s", $phone)."$fax\n";
?>

Refactoring

<?php
$formated = sprintf("%-44.44s%s\n", $firstname, $lastname);
$formated .= sprintf("%-39.39s%-15.15s%-3.3s%s\n", $street, $city, $state, $zip);
$formated .= sprintf("%-10.10s%s\n", $phone, $fax);
?>

This works perfectly and allows me to seperate everything out nice and neat, thanks!

Nice responses.  I see some really valuable code throughout this post.
