What information is in the two arrays you have? It may be that we need to adjust the code to include quote marks if the data in the array contains spaces.
Also are you getting an error message - what is the message exactly?

the file contains
name:pradeep
palce:blore
i am taking the 1st line into data and then using explode so as 2 split into 2 arrays say name and pradeep..and storing them in name[$i] and value[$i]
then i am moving to next line wit help of $x+1024 and then splitting the 2nd line also..
then using the variables in the html form..
there is no proper error ..but its displaying jst tht wht i said in last msg.

explode() will generate one array:
[PHP]
<?php
$lcFileContent = file(_FileName_ );
$laTest = explode(":", $lcFileContent) ;
print_r($laTest );
[/PHP]
This single array will then contain 'name' and 'pradeep'. The code abpve will print the array and you will be able to see what is in it and how best to manipulate.

but this is wht in found i php manual
If you want to split a price (float) into pounds and pence.
or dollors and cents etc etc.
$price = "6.20";

$pound = $split[0]; // piece1

First of all please use CODE tags, it makes reading your post much easier!
Second, you may be in a panic but I'm just trying to help and perhaps you need to take a breather before reading this and come back to it with a clearer mind. I know I need to do that sometimes.
The code sample you posted
[PHP]
$price = "6.20";
$split = explode(".", $price);
$pound = $split[0]; // piece1 - "6"
$pence = $split[1]; // piece2 - "20"
echo "£ $pound . $pence\n";
[/PHP]
Simply takes string and splits on the occurrence of '.' into one array called $split. This array has numeric keys, starting at 0 and can be referenced accoridingly.
In your case all that is different is the source of the original string - you want it to come from a file.
What you need to do, is what you were doing earlier (I showed the file() function and print_r() to help you understand what happens with the xplode function).
Open the file and loop through one line at a time.
For each line create a variable of the line.
Explode the variableit into an array
Loop through this array (this is now a nested loop)
This array will, according to your data structure, contain a pair of values, do what you want with these. Note; as its a numeric array it is simple to loop with a for loop based on the count() of the array - remember arrasy start counting at 0.
This is the psuedo code for you. Just write it up. I've given enough help now on this. I do have a job to do myself you know, with my own deadlines to meet - you're not the only one under pressure.
If you write the code, as outlined, and need some help post it back here with lots of information and use the CODE or PHP tags to format it.
