php file read function

Question

I am using the following file read

$myFile = "file.txt";
$fh = fopen($myFile, 'r');
$theData = fread($fh, filesize($myFile));
fclose($fh);
echo $theData;

problem is file.txt is generating dynamically and is in different folder so how do I call it in fopen ? I am trying

$fh = fopen(/path/to/$myFile, 'r');

but obviously its not working and giving me error

PHP Parse error:  syntax error, unexpected '/',

how to rectify this and include my path ?

@PLB It works But further giving me error PHP Warning: filesize() [function.filesize]: stat failed and PHP Warning: fread() [function.fread]: Length parameter must be greater than 0 — user1561466, Aug 03 '12 at 13:21

This is a simpler way:

$theData = file_get_contents("/path/to/file/" . $myFile);

With this way you do not need to open the file, stat it and all the other stuff, this returns the file contents with a single command. – Maerlyn Aug 03 '12 at 13:42

First off, it'd be simper just to use file_get_contents()

As to the file path, that needs to be a string, i.e.:

$fh = fopen("/path/to/".$myFile, 'r');

Always use single quotes for simple strings and you never have to worry about escaping... – inVader Aug 03 '12 at 13:12

@inVader False. `$myStr = 'Matt\'s string';` – Matt Aug 03 '12 at 13:15
@Matt - Right, yeah... but nevertheless, single quotes are the way to go if you don't have variables or special characters. – inVader Aug 03 '12 at 13:17
@inVader Agreed. I was just pointing out information that might confuse a newbie. – Matt Aug 03 '12 at 13:18
Single quotes are also faster in PHP because it doesn't have to parse them for variables. – SomeKittens Aug 03 '12 at 13:20
That's a myth, if you don't have any `$` signs in it, there's no measurable difference. – Maerlyn Aug 03 '12 at 14:30

$myPath = "/path/to/file/";
$myFile = "file.txt";
$fh = fopen($myPath.$myFile, 'r');
$theData = fread($fh, filesize($myFile));
fclose($fh);
echo $theData;

I haven't tested it, but I guess it will work that way...

You have to change the 4th line to `$theData = fread($fh, filesize($myPath.$myFile));` – silentw Aug 06 '12 at 15:23

I have tried to solve this problem in my own way. Hope this will help you.

<?php

$myFile = "folder/file.txt";
$myHandle = fopen($myFile, "r");

$myData = fread($myHandle, filesize($myFile));
$rows = explode(" ", $myData);

foreach($rows as $row) 
{
    print $row;
}

fclose($myHandle);

?>
