.php5 versus .php

I am working in two environments neither configuration of
which I can change; one's my Web host the other a client.

My Web host requires the use of the ".php5" extension
to use PHP v5.1.4; where ".php" is used for PHP v4.3.11.
My client supports PHP v5.2.0 with the ".php" extension.

Is there a way to reliably determine if the ".php5" extension
must be used on a server? Perhaps via a "phpinfo()" value?

I have a page that uses the v5 function "file_put_contents()".
(I like it's LOCK_EX feature.)

Thanks in advance.

I tried this (to not write to the file in the function isn't supported):

try {
file_put_contents($file, $text, FILE_APPEND+LOCK_EX);
} catch (Exception $e) {
echo "Caught exception: ", $e->getMessage(), "\n";
}

but got this error:

Parse error: parse error, unexpected '{' ...

It doesn't like my use of "try - catch".
Why isn't "try - catch" documented?
I found only one reference; (under "Exceptions").

Usefull for determening current PHP / newer functionality:
<http://www.php.net/phpversion>
<http://pear.php.net/package/PHP_Compat>

Now, I have no idea how to find out the addtype declarations in apaches
configuration with PHP, but this cumbersome workaround will probably work:

----checktype.php5--
echo PHP_VERSION;

---check.php--------
echo "Current .php version is ".PHP_VERSION."\n";
$path = 'http://'.$_SERVER['HTTP_HOST'].dirname($_SERVER['PHP_SELF']).'/';
$php5 = file_get_contents($path.'checktype.php5');
if(preg_match('/^<\?/',$php5)){
echo ".php5 is not supported as an extention";
} else {
echo ".php5 uses version ".$php5;
$result = version_compare(PHP_VERSION,$php5);
if($result == 0){
echo "\nversions are equal";
} else {
echo "\nversion used for .php5 is ".(($result==-1)?'higher':'lower');
}
}

re: .php5 versus .php

McKirahan kirjoitti:Don't know if these help you any but two observations:

1) you can get the version of php with phpversion();
http://fi.php.net/manual/en/function.phpversion.php

2) You can test wether a function exists with

if(function_exists('file_put_contents')){
file_put_contents($file, $text, FILE_APPEND+LOCK_EX);
} else {
echo "craptastic!";
}

try

catch (Exception $e)

(should have been a dot after caught exception)

as for .php5, just use an .htaccess file to rewrite all extensions of
one sort to the other, whatever suits. 1and1 are like this, but the
htaccess rewrite rules work fine.

Please notify the PHP Documentation Group; here's their example:

Chapter 20. Exceptions

Example 20-1. Throwing an Exception

<?php
try {
$error = 'Always throw this error';
throw new Exception($error);

// Code following an exception is not executed.
echo 'Never executed';

} catch (Exception $e) {
echo 'Caught exception: ', $e->getMessage(), "\n";
}

// Continue execution
echo 'Hello World';
?>

The gag here is that when using a dot, you're concatenating two strings,
when using a comma your passing two (or more) arguments to echo, so the
comma thing only works with echo which is capable of recieveing arbitrary
number of parameters, unlike print for example. Thus print('foo','bar')
doesn't work while echo('foo','bar') does. Actually it might save just a
teeny bit of cpu cycles if the strings aren't concatenated but instead
passed as separate parameters. Go figure. For the sake of readability, using
dots consistently might be wise.

Thinking that after a long satisfying trial of Opera it may very well be

cool thing about the user notes on php.net's docs, is that if there
are any backward compatibility issues, users will usually post
workaround functions. Over time, they generally get more efficient, as
one person tries to do the same thing more efficiently than the last.
The user notes aren't validated though, so you need to have your wits
about you when it comes to making sure code won't become a security risk.

Rik kirjoitti:Normal functions are also capable of recieveing an arbitrary number of
parameters. Print just isn't programmed to handle them. It's true that
echo is a language construct, but that doesn't make it magical.

Something like this should work: (didn't test thou)

function print_multiple(){
foreach(func_get_args() as $arg)
print($arg);
}

print_multiple('Hello', ' ', 'world!'); // Using commas instead of dots.
