When I try and unserialize the following string:
a:3:{i:0;s:19:\"Sales+%2F+Customers\";i:1;s:78:\"Micro+Business+%28less+than+10+employees+%26+turnover+under+%C2%A32+million%29\";i:2;s:13:\"Manufacturing\";}
It returns false and I get the following warning:
WARNING: Error at offset 9 of 158 bytes
It was generated by calling serialize on an array though and looks valid to me though, I don't understand what the problem is?
The slashes aren't valid in this case, use stripslashes(). Demo code below:
<pre>
<?php
$x = "a:3{i:0;s:19:\"Sales+%2F+Customers\";i:1;s:78:\"Micro+Business+%28less+than+10+employees+%26+turnover+under+%C2%A32+million%29\";i:2;s:13:\"Manufacturing\";}";
echo "unserializing $x: " . PHP_EOL;
try {
print_r(unserialize($x));
echo PHP_EOL;
} catch (\Exception $e) {
echo $e->getMessage() . PHP_EOL;
}
$y = "a:3{i:0;s:19:\\\"Sales+%2F+Customers\\\";i:1;s:78:\\\"Micro+Business+%28less+than+10+employees+%26+turnover+under+%C2%A32+million%29\\\";i:2;s:13:\\\"Manufacturing\\\";}";
echo "unserializing $y: " . PHP_EOL;
try{
print_r(unserialize($y));
echo PHP_EOL;
} catch (\Exception $e) {
echo $e->getMessage() . PHP_EOL;
}
echo "unserializing stripslashes($y): " . PHP_EOL;
try{
print_r(unserialize(stripslashes($y)));
} catch (\Exception $e) {
echo $e->getMessage() . PHP_EOL;
}
?>
</pre>

My question is about the correct way to catch exceptions in PHP.
Based on the accompanying examples of the PHP MongoDB driver, I
have created the following script:
<?php
try {
$mng = new MongoDB\Driver\Manager("mongodb://localhost:2717");
$query = new MongoDB\Driver\Query([], ['sort' => [ 'name' => 1], 'limit' => 5]);
$rows = $mng->executeQuery("testdb.cars", $query);
foreach ($rows as $row) {
echo "$row->name : $row->price\n";
}
} catch (MongoDB\Driver\Exception\Exception $e) {
$filename = basename(__FILE__);
echo "The $filename script has experienced an error.\n";
echo "It failed with the following exception:\n";
echo "Exception:", $e->getMessage(), "\n";
echo "In file:", $e->getFile(), "\n";
echo "On line:", $e->getLine(), "\n";
}
?>
The example is educational and meant to be run on the PHP CLI. In PHP CLI, we get all the exceptions on the console, but for didactic purposes, I wanted to catch exceptions in the try/catch block.
I have seen more Java code than PHP and therefore, catching a generic MongoDB\Driver\Exception\Exception does not look good to me. In Java, we catch specific exceptions and have multiple try/catch blocks for different kinds of exceptions.
The driver has the following Exceptions:
MongoDB\Driver\Exception\AuthenticationException
MongoDB\Driver\Exception\BulkWriteException
MongoDB\Driver\Exception\ConnectionException
MongoDB\Driver\Exception\ConnectionTimeoutException
MongoDB\Driver\Exception\Exception
MongoDB\Driver\Exception\ExecutionTimeoutException
MongoDB\Driver\Exception\InvalidArgumentException
MongoDB\Driver\Exception\LogicException
MongoDB\Driver\Exception\RuntimeException
MongoDB\Driver\Exception\SSLConnectionException
MongoDB\Driver\Exception\UnexpectedValueException
MongoDB\Driver\Exception\WriteException
Is this a kosher way to catch exceptions in PHP?
How about placing a switch statement in the catch part, and determine the exception's type with the instanceof language construct or the get_class() function?
For example:
[...]
} catch(\Exception $e) {
switch (get_class($e)) {
case 'MongoDB\Driver\Exception\AuthenticationException':
// do stuff
break;
case 'MongoDB\Driver\Exception\BulkWriteException':
//etc, etc...
}
}
At first, I would examine the return values of get_class(), to make sure you I'm comparing the result with the exact exception names.
You can add multiple catch statements
<?php
try {
$mng = new MongoDB\Driver\Manager("mongodb://localhost:2717");
$query = new MongoDB\Driver\Query([], ['sort' => [ 'name' => 1], 'limit' => 5]);
$rows = $mng->executeQuery("testdb.cars", $query);
foreach ($rows as $row) {
echo "$row->name : $row->price\n";
}
} catch (MongoDB\Driver\Exception\AuthenticationException $e) {
echo "Exception:", $e->getMessage(), "\n";
} catch (MongoDB\Driver\Exception\ConnectionException $e) {
echo "Exception:", $e->getMessage(), "\n";
} catch (MongoDB\Driver\Exception\ConnectionTimeoutException $e) {
echo "Exception:", $e->getMessage(), "\n";
}
?>
Adding multiple catch statement I think it's a better approach than switch. However, what if the exception isn't from these classes with a switch you should have a default case and also if you do it with multiple catches.
try {
$mng = new MongoDB\Driver\Manager("mongodb://localhost:2717");
$query = new MongoDB\Driver\Query([], ['sort' => [ 'name' => 1], 'limit' => 5]);
$rows = $mng->executeQuery("testdb.cars", $query);
foreach ($rows as $row) {
echo "$row->name : $row->price\n";
}
} catch (MongoDB\Driver\Exception\AuthenticationException $e) {
echo "AuthenticationException:", $e->getMessage(), "\n";
} catch (MongoDB\Driver\Exception\ConnectionException $e) {
echo "ConnectionException:", $e->getMessage(), "\n";
} catch (MongoDB\Driver\Exception\ConnectionTimeoutException $e) {
echo "ConnectionTimeoutException:", $e->getMessage(), "\n";
}catch (\Exception $e) {
echo "Exception:", $e->getMessage(), "\n";
}
I've got a Search class, which has

}
}
public function find($query, $eventId)

{

$query = "($query) AND (event_id:$eventId)";
Zend_Search_Lucene::setResultSetLimit(self::ACCREDITATION_LIMIT);
return $this->_indexes[$this->_key]->find("{$query}");
}
catch (Zend_Search_Lucene_Search_QueryParserException $e)

catch (Exception $e)

I've got a record with name Test, when I'm looking for Test it works, but can't find this record with request test
Code example:
$s = new Search();
$s->find('test', 1232);//no results
I found a solution, the problem was that I was saving fields (name, etc.) as keyword, I changed it to text, and now it's working perfectly.
Is there a way on including a file at the beginning of a class for all methods to use. The example below is a simplified version of what I am trying to achieve. Currently I have to include the file within every method.
Example Logic (not working)
class Myclass
{
protected require_once 'folerd1/folder2/pear/HTTP/Request2.php'; // this does not work
public function aMethod()
{
$request = new HTTP_Request2('http://example1.com/', HTTP_Request2::METHOD_GET);
try {
$response = $request->send();
if (200 == $response->getStatus()) {
echo $response->getBody();
} else {
echo 'Unexpected HTTP status: ' . $response->getStatus() . ' ' .
$response->getReasonPhrase();
}
} catch (HTTP_Request2_Exception $e) {
echo 'Error: ' . $e->getMessage();
}
}
public function aMethod1()
{
$request = new HTTP_Request2('http://example2.com/', HTTP_Request2::METHOD_GET);
try {
$response = $request->send();
if (200 == $response->getStatus()) {
echo $response->getBody();
} else {
echo 'Unexpected HTTP status: ' . $response->getStatus() . ' ' .
$response->getReasonPhrase();
}
} catch (HTTP_Request2_Exception $e) {
echo 'Error: ' . $e->getMessage();
}
}
// more methods
}
2 solution
1) require_once taken outside from class
require_once 'folerd1/folder2/pear/HTTP/Request2.php';
class Myclass
{
2) Include in the construct
public function __construct() {
require_once 'folerd1/folder2/pear/HTTP/Request2.php';
}
But it is better first option
The best way is to look at autoloading standard http://www.php-fig.org/psr/psr-0/
Have you tried this? I don't know what's your Request2.php file content. So my code is only a PoC!
require 'folerd1/folder2/pear/HTTP/Request2.php';
class Myclass
{
public function aMethod()
{
$request = new Request2('http://example1.com/', Request2::METHOD_GET);
try {
$response = $request->send();
if (200 == $response->getStatus()) {
echo $response->getBody();
} else {
echo 'Unexpected HTTP status: ' . $response->getStatus() . ' ' .
$response->getReasonPhrase();
}
} catch (Request2_Exception $e) {
echo 'Error: ' . $e->getMessage();
}
}
public function aMethod1()
{
$request = new Request2('http://example2.com/', Request2::METHOD_GET);
try {
$response = $request->send();
if (200 == $response->getStatus()) {
echo $response->getBody();
} else {
echo 'Unexpected HTTP status: ' . $response->getStatus() . ' ' .
$response->getReasonPhrase();
}
} catch (Request2_Exception $e) {
echo 'Error: ' . $e->getMessage();
}
}
}
As I commented out, just require the file in the constructor of the PHP class:
class Myclass{
function Myclass(){
require_once('folerd1/folder2/pear/HTTP/Request2.php');
}
I have not checked this, but it MIGHT be possible that what you're just doing is including it not only for all the class to see, but the entire script. Please, check that out if it is a problem for you. If not, the other 2 solutions might end up doing the same.
Cheers
