phpversion() and sqlite_libversion() not returning anything
I am on a corporate hosting solution, and trying to test for the existence of sqlite. I am running the
following code:
<?php
echo sqlite_libversion(), "\n", phpversion();
?>
But I am getting a blank page. I know PHP is running because phpinfo() is successful, however
this is not enough to tell me if sqlite is running as the sqlite.ini is present in phpinfo() but can't
find any other information.
I am accessing the server via FTP and am locked into the web-root. Does anyone know why
phpversion() and sqlite_libversion() are returning nothing?
<?php
if (function_exists('phpversion')) {
echo "La funzione phpversion() e' disponibile nella versione ";
echo phpversion();
echo "<br />";
echo "<br />";
} else {
echo "La funzione phpversion() non e' disponibile.<br />\n";
}
if (function_exists('sqlite_libversion')) {
echo "La funzione sqlite_libversion() e' disponibile nella versione ";
echo sqlite_libversion();
echo "<br />";
echo "<br />";
} else {
echo "La funzione sqlite_libversion() non e' disponibile.<br />\n";
}
?>

If the SQLite is not available, the sqlite_libversion() function will not even exist and will just
throw a PHP error:
Fatal error: Call to undefined function sqlite_libversion()
You need to use function_exists() to test if the function is actually there.
Additionally, you should configure error reporting so you can actually see error messages. You have
several ways to do so:
1. Edit your php.inifile:
error_reporting = E_ALL | E_STRICT
display_errors = On
2. Put this on top of your script:
<?php
error_reporting(E_ALL | E_STRICT);
ini_set('display_errors', TRUE);
3. If PHP runs as Apache module, you can also use an .htaccess file:
# Print E_ALL | E_STRICT from a PHP script to get the appropriate number:
php_value error_reporting 2147483647
php_flag display_errors on
Update:
What do you get if you run this code and nothing else?
<?php
error_reporting(E_ALL | E_STRICT);
ini_set('display_errors', TRUE);
header('Content-Type: text/plain');
var_dump(phpversion());
if( function_exists('sqlite_libversion') ){
var_dump(sqlite_libversion());
}
?>

Unfortunately I am locked into web-root and option 2 is not showing any errors.
This is also showing nothing:
echo (function_exists ("sqlite_libversion")) ? "sqlite exists":"not here";

See my update

Cheers I get this: string(15) "5.2.6-1+lenny13"
It's not installed, an error on the page was stopping the
function_exists() from running.
–------------------------------------------------------------------------------take out the echo, just do
<?php
phpversion();
sqlite_libversion();
?>
