I would think the following piece of code should work, but it doesn't (Edited: Now works in PHP 5.5+):
if (!empty($r->getError()))
Where getError() is simply:
public function getError()
{
return $this->error;
}
Yet I end up with this error:
can't use method return value in write context
What does this mean? Isn't this just a read?
Replace the first if statement with if( ! $this->session->userdata('user_id') ).
The empty function check if a variable is empty but userdata is a function. Additionally, for your information, according to the CodeIgniter documentation, the userdata function returns FALSE if the item doesn't exist, which means that if user_id doesn't exist in your session, the code in the else will be executed.
You mean
if (isset($_POST['sms_code']) == TRUE ) {
though incidentally you really mean
if (isset($_POST['sms_code'])) {
Here's what worked best for me when trying to script this (in case anyone else comes across this like I did):
$ pecl -d php_suffix=5.6 install <package>
$ pecl uninstall -r <package>
$ pecl -d php_suffix=7.0 install <package>
$ pecl uninstall -r <package>
$ pecl -d php_suffix=7.1 install <package>
$ pecl uninstall -r <package>
The -d php_suffix=<version> piece allows you to set config values at run time vs pre-setting them with pecl config-set. The uninstall -r bit does not actually uninstall it (from the docs):
vagrant@homestead:~$ pecl help uninstall
pecl uninstall [options] [channel/]<package> ...
Uninstalls one or more PEAR packages. More than one package may be
specified at once. Prefix with channel name to uninstall from a
channel not in your default channel (pecl.php.net)
Options:
...
-r, --register-only
do not remove files, only register the packages as not installed
...
The uninstall line is necessary otherwise installing it will remove any previously installed version, even if it was for a different PHP version (ex: Installing an extension for PHP 7.0 would remove the 5.6 version if the package was still registered as installed).
Try changing
if(!isset($_COOKIE(user_id)))
to
if(!isset($_COOKIE['user_id']))
^^ ^^
$_COOKIE is an associative array.
Never used any of those, but they look interesting..
Take a look at Gearman as well.. more overhead in systems like these but you get other cool stuff :) Guess it depends on your needs ..
empty()needs to access the value by reference (in order to check whether that reference points to something that exists), and PHP before 5.5 didn't support references to temporary values returned from functions.However, the real problem you have is that you use
empty()at all, mistakenly believing that "empty" value is any different from "false".Empty is just an alias for
!isset($thing) || !$thing. When the thing you're checking always exists (in PHP results of function calls always exist), theempty()function is nothing but a negation operator.PHP doesn't have concept of emptyness. Values that evaluate to false are empty, values that evaluate to true are non-empty. It's the same thing. This code:
and this:
has always the same result, in all cases, for all datatypes (because
$xis definedempty()is redundant).Return value from the method always exists (even if you don't have
returnstatement, return value exists and containsnull). Therefore:is logically equivalent to:
