[Reading contents from file but substitute variable wth value]

I am trying to write a PHP application where an automatic response is sent out after form is posted.

The contents of the email was to be read from a file, but I would like to exchange the variable in the file to the actual value of it.

 

For example, there is a <form> and my user posted his name as "Andy".

I would like my automatic response email to be appear like the following where the name is the value which the user posted.

-----------------------

Dear Andy,

Thank you for posting.

We will contact you soon.

-----------------------

 

However i just get the following result: ???

-----------------------

Dear $name,

Thank you for posting.

We will contact you soon.

-----------------------

 

Could anyone tells me what's wrong with my code? 

 

My function looks like this:

PHP Program

// $inc = the file contents to be wrote in the email (data.txt)
function Send_Notification($mail_to, $mail_cc, $name, $inc){
    $mail_from = MAILFROM;
    $mail_subject = SUBJECT;

    $fp = fopen($inc, "r");
    while(!feof($fp)){
        $buffer .= fgets($fp);
    }

    $headers = "From: $mail_from";
    $headers.= "Bcc: $mail_from";

    $body .= $buffer;

    if(!mb_send_mail($mail_to, $mail_subject, $body,$headers)){
        return false;
    }
}

data.txt

Dear $name,
Thank you for posting.
We will contact you soon.

 

Thank you

[comparison of date with PHP]

thanks ifa and redarrow

found one way.
put all the dates in an array
sort it
and get the first and last element :)

[comparison of date with PHP]

is there anyway i can compare 3 or more date type column?

let's say i have
------------------------------------------------
date1  |  date2 | date3
------------------------------------------------
2006-06-01 | 2006-06-15 | 2006-09-19
------------------------------------------------

and my select statement returns this 3 value.

is there any way i can write in PHP to get the earliest or the latest date?
let's say:
[code]
$earliest = XXX($row[date1], $row[date2], $row[date3])  <- returns ("2006-06-01")

$latest = XXX($row[date1], $row[date2], $row[date3])  <- returns ("2006-09-19")
[/code]

i tried to get these from mysql command like if possible but cant find any way to do it..
i guess there's no function to this..
select XXXXX(date1,date2,date3)  <--returns '2006-06-01 '
select YYYYY(date1,date2,date3)  <--returns '2006-09-19

[how to edit file's contents with php(insert line in between)]

willfitch,
thanks for the reply
but i still get the result as following
[quote]
apple1
orange2
lime3
strawberry4
newlinele5
mango6
[/quote]

my code is as following:
[code]
<?php
$file = file("data/file.txt");

foreach($file as $line_number => $contents){
   if(trim($contents) == 'strawberry'){
       fputs($fp, "newline");
   }
}
?>
[/code]

is it that fputs isnt a good idea?

Well,

If you are hard-coding your parameters with your if conditions, you could use file() and do a foreach() loop and loop through each line.  Once you hit the strawberry, insert your new line.
[code=php:0]
<?php
$file = file('file.txt');
foreach($file as $line_number => $content) {
    if (trim($content) == 'strawberry') {
        // do your thing here.
    }
}
?>
[/code]

[how to edit file's contents with php(insert line in between)]

i have a file with the contents of :
[quote]
apple1
orange2
lime3
strawberry4
pineapple5
mango6
[/quote]

i would like to insert one newline "newline" in between "lime3" and "strawberry4"

first i wrote my code like this:
[code]
<?php

$fp = fopen("data/file.txt", "r+");

while($buf = fgets($fp)){
    if(preg_match("/strawberry/", $buf)){
        fputs($fp, "newline\n");
    }
}
?>
[/code]
but it ended up like this:
[quote]
apple1
orange2
lime3
strawberry4
newline
e5
mango6
[/quote]

so i changed my code to the following (omitting \n at the end of "newline")
[code]
<?php

$fp = fopen("data/file.txt", "r+");

while($buf = fgets($fp)){
    if(preg_match("/strawberry/", $buf)){
        fputs($fp, "newline");
    }
}
?>
[/code]

but i got the result of
[quote]
apple1
orange2
lime3
strawberry4
newlinele5
mango6
[/quote]

i cant seem to have a line inserted in between..
it replaces the line after it..

i would appreciate any help
thanks
