I have a bit type value hasFreePackage in database which stores 1 or 0.
Here is my code below, This is working on my localhost and but whenever i try to upload on live server this code doesn't work.
public function checkBitValue($hasFreePackage)
{
$hasFreePackage= ($hasFreePackage== 0x01)
if($hasFreePackage==1)
return 1;
else
return 0;
}
As live server is linux platform and i'm running windows on local. my code works on windows but not on linux So i changed my code to this code..
public function checkBitValue($hasFreePackage)
{
$FreePackage= ($hasFreePackage== 0x01)
if($FreePackage==1)
return 1;
elseif(ord($FreePackage==1))
return 1;
else
return 0;
}
but still not working. I'm using yii 1.1 php framework and php versions are different.At linux is 5.2.0 and at local (windows) is 5.7
Even simpler:
{
return $hasFreePackage ? 1 : 0;
}
Or, more clearly:
{
return $hasFreePackage ? TRUE : FALSE;
}
The rationale: 0 is FALSE; non-zero numbers are TRUE.
Still better: Keep that in mind and don't bother checking true/false value against true/false!
Caution: NULL and '' muddy up logic like this. Hence the "rationale" spoke only of numbers.

We are upgrading PHP to version 8.1. Using MS Sql Server DB. It all seems to work correctly but I see repeated messages in the log file:
[03-Feb-2022 11:51:18 America/New_York] PHP Deprecated: Automatic conversion of false to array is deprecated in C:...\includes\adodb\drivers\adodb-mssqlnative.inc.php on line 154
I've updated adodb to version version 5.22 but that did not stop the messges from logging. The ini file has
extension=php_sqlsrv_81_nts_x64.dll
extension=php_pdo_sqlsrv_81_nts_x64.dll
Does anyone know how to fix this problem?
This is a known issue of backwards incompatibility, affecting the ADOdb library version 5.22.1 and older. PHP 8.1 warns you on autovivification of false-y values and some future version of PHP will throw an error when you do it.
PHP natively allows for autovivification (auto-creation of arrays from falsey values). This feature is very useful and used in a lot of PHP projects, especially if the variable is undefined. However, there is a little oddity that allows creating an array from a false and null value.
And they give this example
// From false
$arr = false;
$arr[] = 2;
I went and found the file in question and this is the function it's in
function ServerInfo() {
global $ADODB_FETCH_MODE;
static $arr = false;
if (is_array($arr))
return $arr;
if ($this->fetchMode === false) {
$savem = $ADODB_FETCH_MODE;
$ADODB_FETCH_MODE = ADODB_FETCH_NUM;
} elseif ($this->fetchMode >=0 && $this->fetchMode <=2) {
$savem = $this->fetchMode;
} else
$savem = $this->SetFetchMode(ADODB_FETCH_NUM);
$arrServerInfo = sqlsrv_server_info($this->_connectionID);
$ADODB_FETCH_MODE = $savem;
$arr['description'] = $arrServerInfo['SQLServerName'].' connected to '.$arrServerInfo['CurrentDatabase'];
$arr['version'] = $arrServerInfo['SQLServerVersion'];//ADOConnection::_findvers($arr['description']);
return $arr;
}
The problem is that it starts with
static $arr = false;
and then tries to autovivificate a non-array (line 154 in your error)
$arr['description'] = $arrServerInfo['SQLServerName'].' connected to '.$arrServerInfo['CurrentDatabase'];
You should be able to fix it (in theory) by making sure it's an array (something they should have done anyways). Add this above that line to make it one before it tries to append
if(!is_array($arr)) $arr = [];
Im using Vision API Client Library for PHP.
This is my code:
use Google\Cloud\Vision\V1\ImageAnnotatorClient;
putenv("GOOGLE_APPLICATION_CREDENTIALS=/json.json");
$imageAnnotator = new ImageAnnotatorClient();
$fileName = 'textinjpeg.jpg';
$image = file_get_contents($fileName);
$response = $imageAnnotator->labelDetection($image);
$labels = $response->getLabelAnnotations();
if ($labels) {
echo("Labels:" . PHP_EOL);
foreach ($labels as $label) {
echo($label->getDescription() . PHP_EOL);
}
} else {
echo('No label found' . PHP_EOL);
}
And I receive this error:
Error occurred during parsing: Fail to push limit. (0)
/srv/www/site.ru/htdocs/vendor/google/protobuf/src/Google/Protobuf/Internal/CodedInputStream.php:345
#0: Google\Protobuf\Internal\CodedInputStream->pushLimit(integer)
/srv/www/site.ru/htdocs/vendor/google/protobuf/src/Google/Protobuf/Internal/CodedInputStream.php:368

....
....
....
#15: Google\Cloud\Vision\V1\ImageAnnotatorClient->labelDetection(string)
/srv/www/site.ru/htdocs/local/php_interface/GoogleCloud.php:41
This is the place, where Exception goes from:
public function pushLimit($byte_limit)
{
// Current position relative to the beginning of the stream.
$current_position = $this->current();
$old_limit = $this->current_limit;
// security: byte_limit is possibly evil, so check for negative values
// and overflow.
if ($byte_limit >= 0 &&
$byte_limit <= PHP_INT_MAX - $current_position &&
$byte_limit <= $this->current_limit - $current_position) {
$this->current_limit = $current_position + $byte_limit;
$this->recomputeBufferLimits();
} else {
throw new GPBDecodeException("Fail to push limit.");
}
return $old_limit;
}
$byte_limit <= $this->current_limit - $current_position is true
Should I increase current_position? And if I should, how can i do it? Change something on server or in PHP config?
It's a crazy thing to do!
The error "Fail to push limit" appears from time to time in forums. Various ideas are given there as to where the problem could lie. One cause could be when the source code is composed on the local PC via Composer and then transferred to the server via (S)FTP. The FTP programme decides on the basis of the file extension whether it saves the data on the server in ASCII or binary format.
In vendor/google/protobuf/src/Google/Protobuf/ there are various generated files that have a .php extension but are actually BINARY! (if you open the file, you can see it immediately, e.g. : vendor/google/protobuf/src/GPBMetadata/Google/Protobuf/Any.php)
The solution to transfer these files explicitly via binary to the server worked in my case! If in doubt, transfer the complete module from Google/protobuf as a binary...
You mentioned that $byte_limit <= $this->current_limit - $current_position is true, so either $byte_limit >= 0 or $byte_limit <= PHP_INT_MAX - $current_position are false.
If $byte_limit <= PHP_INT_MAX - $current_position is false, then increasing $current_position, won't turn it true. If you want to tweak the values, so the expression get evaluated as true, you would need to increase the value of PHP_INT_MAX instead.
If $byte_limit >= 0 is false, then modifying $current_limit won't avoid the exception.
Either way, it seems that the error is an issue with the protobuf php library, so I'd recommend you to report the issue there, rather than try to modify the values directly.
mbstring.func_overload was 2
This was the reason of error
Changed to 0 and it worked
I want to get the name of all keys for memcached, but Memcached::getAllKeys method always return false.
use contos 6.5 + memcached 1.4.31 + php-memcached-2.2.0 PECL
It looks like newer versions of memcached don't like nor support the getAllKeys method.
However it looks like someone made it work by setting
Memcached::OPT_BINARY_PROTOCOL = false
If it does not work I think you have to fall back to 1.4.23 version or install REDIS :P
I had the same problem on my live server. I was preparing a test to show the techs there how to replicate my problem:
$m = new Memcached();
$m->addServer(MEMCACHED_SERVER, MEMCACHED_PORT);
echo "added ". MEMCACHED_SERVER. ":". MEMCACHED_PORT. PHP_EOL;
$keys = [];
$stop = 100;
foreach( $m->getAllKeys() as $k){
array_push( $keys, $k );
if( --$stop == 0 ) break;
}
var_dump( $keys );
this would return 100 keys on my local R&D server, but an empty list on the live server. To show them there was definitely something in there I echoed a dump of a key in there that I knew for sure was there:
var_dump( $m->get( "cache:pool:70:230" ));
that line showed there was a key, but it also made getAllKeys to return a list of 100 entries more! I still believe this is a bug, but there is a workaround.
Edit: Turns out any redundant call before getallkeys fixes this: $m->getVersion(); would also make getAllKeys works
I have a bit of PHP code that works fine on my production server but not on my test server. Here is the code:
function callProcedure0(&$connection, $procname, $dofunction)
{
mysqli_multi_query($connection, "CALL " . $procname . "();");
$first_result = 1;
do
{
$query_result = mysqli_store_result($connection);
if ($first_result)
{
$dofunction($query_result);
$first_result = 0;
}
if ($query_result)
{
mysqli_free_result($query_result);
}
$query_result = NULL;
} while(mysqli_next_result($connection));
}
...
function doGenres($in_result)
{
global $genre_array, $game_array, $genre_order_array;
$genre_count = 1;
// foreach is necessary when retrieving values since gaps may appear in the primary key
while ($genre_row = mysqli_fetch_row($in_result)) // line 81 is here!
{
$genre_array[] = $genre_row[0];
$genre_order_array[$genre_row[1] - 1] = $genre_count;
$game_array[] = [[],[]];
$genre_count += 1;
}
}
...
callProcedure0($con, "get_genres_front", doGenres); // line 138 is here!
The "get_genres_front" bit refers to a stored procedure on my database. Here are the errors:
Notice: Use of undefined constant doGenres - assumed 'doGenres' in /opt/lampp/htdocs/keyboard/keyboard.php on line 138
Again, there are no problems on the production server which is using Apache 2.2.23, MySQL 5.1.73-cll, PHP 5.4.26. The test server where things are broken is running Apache 2.4.10, MySQL 5.6.21, PHP 5.5.19.
Did something change in recent software versions? Thanks.
[edit]
This is not a duplicate question. I'm worried about the first error. I already know what to do about the second error which I have deleted.
The code you have posted is wrong, you must pass function name as string and then use call_user_func to invoke this function.
In your callProcedure0 function change
$dofunction($query_result);
to
call_user_func($dofunction, $query_result);
And then call it with the function name as string like this
callProcedure0($con, "get_genres_front", "doGenres");
The above code could work also with invoking the function with
$dofunction($query_result);
on some php versions, but the line where you pass the function name it should be string, otherwise PHP assumes it is a constant.
How would I add an IF statement to check if the opencart version is greater than 1.5.1.3?
This is defined in the index.php as:
// Version
define('VERSION', '1.5.0');
I have tried: if((int)VERSION >= '1.5.1.3'){ although when I convert this into an int it becomes empty.
Also I tried this with the same effect:
$this->data['oc_version'] = (int)str_replace('.', '', VERSION);
if($this->data['oc_version'] >= 1513){
Do I need to convert this into an int to correctly perform greater/less than calculations?
if(version_compare(VERSION, '1.5.1.3', '>')) {
// CODE HERE IF HIGHER
} else {
// CODE HERE IF LOWER
}
Though the 1.5.1.3 branch actually goes up to 1.5.1.3.1 so I'm guessing you want it to be that
I tried this recently and couldnt get it working as above, perhaps its a PHP version thing but I got it working with:
if(version_compare(VERSION, '1.5.1.3') > 0) {
// CODE HERE IF HIGHER
} else {
// CODE HERE IF LOWER
}
Hope that helps someone else. Got the code from here: http://us2.php.net/manual/en/function.version-compare.php
