[Resolved] php version check

php version checker

---

i want some php code that does like the phpbb version checker

eg i want a file to read a file and if it says something that it expects it will display one message but if the file text is diffrent than what it expects it will display a diffrent message

[wilku]

Example:

<?php
$version = file_get_contents("version.php");
if ($version=="what I expect") echo "This version is OK";
else echo "This is a different version then I expect";
?>

[itunes66]

it does not work here ill show you my code

<?php 
$version = file_get_contents("version.txt"); 
if ($version=="1.0") echo "This version is up to date"; 
else echo "Your version is not up to date the current version is {$version} to download this version"; 
?>

and in version.txt i have
1.0

[bradgrafelman]

Are there extra spaces in version.txt? Extra line breaks, etc?

[itunes66]

yes the cpanel editor automatically it putting in a return so what do i do

[bradgrafelman]

Try this code instead:

<?php  

$version = trim(file_get_contents("version.txt"));
if ($version=="1.0") echo "This version is up to date";
else echo "Your version is not up to date the current version is {$version} to download this version";
?>

i am using this an i get error

Parse error: parse error, unexpected T_ECHO, expecting ',' or ';' in /home/itunes/public_html/photography/admin.php on line 6

some other errors i will get when i fix 1 is

Parse error: parse error, unexpected T_ECHO, expecting ',' or ';' in /home/itunes/public_html/photography/admin.php on line 5

and

Parse error: parse error, unexpected T_ECHO, expecting ',' or ';' in /home/itunes/public_html/photography/admin.php on line 4

here is my code

<?php
$version = trim(file_get_contents("version.txt")); 
if ($version=="1.0")
echo "<h1>version information<h1>";
echo "<font color="#66CC00">";
echo "version up is to date";
echo "</font>";
else
echo "<font color=#FF0000>";
echo "<h1>version information<h1>";
echo "Your version is not up to date the current version is {$version} to download this version"; 
echo "</font>";
?>

hope you can fix this

[wilku]

If you use doublequotes inside doublequotes, escape them:

echo "<font color=\"#66CC00\">";

Notice the change of colour in that line in forum php parser in your post.

i get another error

Parse error: parse error, unexpected T_ELSE in /home/itunes/public_html/photography/admin.php on line 8

here is my code

<?php
$version = trim(file_get_contents("version.txt")); 
if ($version=="1.0")
echo "<h1>version information<h1>";
echo "<font color=\"#66CC00\">";
echo "version up yo date";
echo "</font>";
else
echo "<font color=\"#FF0000\">";
echo "<h1>version information<h1>";
echo "Your version is not up to date the current version is {$version} to download this version"; 
echo "</font>";
?>

😕 😕 😕

If the if statement has more than one line you need to place that block in brackets.

<?php
$version = trim(file_get_contents("version.txt")); 
if ($version=="1.0")
{
     echo "<h1>version information<h1>";
     echo "<font color=\"#66CC00\">";
     echo "version up yo date";
     echo "</font>";
}

else
{
     echo "<font color=\"#FF0000\">";
     echo "<h1>version information<h1>";
     echo "Your version is not up to date the current version is {$version} to download this version"; 
     echo "</font>";
}

?>

ok i fixed it myself i figured that part out but now i erased that code and put it in a file called version.php and i put version.txt and version.php in a file called version and it come up with an error and the page saying that the instlation is not upto date (its the page i made)

[bradgrafelman]

I'm not following what you're saying; post your new code if you changed it.

[itunes66]

i can give you links to the source

http://realbasic-wonders.matrixweb.org/source.php?source=photography/admin.php

http://realbasic-wonders.matrixweb.org/source.php?source=photography/version/version.php
there they are

[bradgrafelman]

Look at the error:

Warning: file_get_contents(/version/version.txt): failed to open stream: No such file or directory in /home/itunes/public_html/photography/version/version.php on line 6

The path should just be 'version.txt' since it resides in the same directory as the script.

[itunes66]

i dont want it in the same directory

[MikeSnead]

Then you need to move that file into the directory so the path you have in the file_get_contents() call is correct.

[itunes66]

but i want to include that code on alot of files
so id rather use includes

[bradgrafelman]

Then use the correct path...

/version/version.txt is not the correct path. Find out your home directory and prepend that, or use $_SERVER['DOCUMENT_ROOT'] to find this directory.

[itunes66]

im new to php so can you give me the code

[drew010]

file_get_contents($_SERVER['DOCUMENT_ROOT'] . "/version/version.txt");
