I just try to integrate ImageMagick into my PHP project. I installed and just execute the sample files that they provided with the imagick-3.0.0RC1 zip file. But it shows
Fatal error: Class 'Imagick' not found in C:\wamp\www\imagick-3.0.0RC1\imagick-3.0.0RC1\examples\watermark.php on line 9
this kind of an error how can I avoid that. I cant see any class including section on that page. How to include the class files.
You need to install the ImageMagick PHP extension. According to the manual there is no prebuilt extension for Windows so you'll probably have to configure and compile it yourself.

When making call to sodium_crypto_pwhash_str I get the following in my Apache error log file.
PHP Fatal error: Uncaught Error: Call to undefined function
sodium_crypto_pwhash_str()
My php version, as noted is 7.3.17 running on an Amazon EC2 instance.
My php-info() does not return any relevant libsodium information other than module author info:
Sodium Frank Denis
Given the above author information references a module author am I supposed to enable the sodium module? If the answer is yes is it referenced in the php.ini file? Such as:
extension=sodium
or perhaps:
extension=libsodium
What am I missing here?
Am I not supposed to use the documented function sodium_crypto_pwhash_str?
Am I supposed to use some other method of accessing the desired functionality?
Yes normally it's included in PHP 7.2+ but when you use the AWS EC2 instances this is a bit minimalistic and not everything is included.
https://www.php.net/manual/de/sodium.installation.php
Here you can see that you have to enable it during the compiling with --with-sodium[=DIR]. So you can compile it on your own or you try another distro to get it from your package manager or you use another lib to make it work.

In PHP (version 7.1), I am attempting to use a MAP as opposed to a two dimensional array to handle implicit data type conversion across different data type groups. However, I am receiving the following run-time error:
Class 'Ds\Map' not found
The error occurs on this line of code:
protected $hive_data_type_group_map = new \Ds\Map();
I have checked online, but there is little documentation on Ds\Map, even on PHP's website (click here). Does anyone know how to fix this?
Data Structures is not a built-in PHP extension.
It needs to be installed before use. The installation instructions are available on php.net.
For windows
Download compiled-dll file "php_ds.dll" from https://pecl.php.net/package/ds. Place it in your dir wamp\bin\php\[your_php_version_folder]\ext and include it in your ".ini" file.
It worked for me.
the easiest way on ubuntu:
pecl install ds

I have a project with PHP 7.3, under Windows 10. I use the PHP from Xampp.
I get the following error:
Fatal error: Uncaught Error: Class 'SplEnum' not found in [...]
for
class BanLevel extends SplEnum { ... }
It seems I am misunderstanding the docu:
https://www.php.net/manual/en/class.splenum.php
https://www.php.net/manual/en/spl.installation.php
This gives me the idea it should be included in my PHP artefact.
What am I missing?
UPDATE:
The class.splenum.php page has gone offline. It is still available in Romanian, though: https://www.php.net/manual/ro/class.splenum.php, or here: https://php-legacy-docs.zend.com/manual/php5/en/class.splenum
It seems I checked the wrong documentation,
this is the right one:
https://www.php.net/manual/en/spl-types.installation.php
It clarifies:
This PECL extension is not bundled with PHP.
A DLL for this PECL extension is currently unavailable.
So I can't use SPLEnum under Windows, except I compile it into PHP.
UPDATE:
The spl-types.installation.php page does not exist on php.net anymore, but it is still available here:
https://php-legacy-docs.zend.com/manual/php5/en/spl-types.installation
I installed the MongoDB PHP driver on Windows 10 (I'm using WAMP equipped with PHP 5.6.25. following the istructions I found at http://php.net/manual/en/mongodb.installation.windows.php and I installed also the libbson and libmongoc libraries (requested as requirements) as written at http://php.net/manual/en/mongodb.requirements.php.
Then, I added the bin folders of MongoDB, libbson and libmongoc to system path.
However, even if I can see the php_mongodb extension in the extensions list of WAMP, launching phpinfo() the mongo extension doesn't appear with the others.
Furthermore, tryng to connect to my database with
<?php
$mongo=new MongoClient("");
$db=$mongo->galileo;
$collection= $db->items;
print_r("Number of documens: "); ?>
I got the error
Fatal error: Class 'MongoClient' not found in C:\wamp64\www\galileo\index.php >on line 21
At a first look, reading this error, it might seem like that PHP is looking for php_mongodb extension in the uncorrect folder i.e. C:\wamp64\www\galileo\index.php (where the index page of my project is placed) instead of the correct one C:\wamp64\bin\php\php5.6.25\ext where all the extensions are.
But, looking at php log file php_error.log I find also a warning that says:
PHP Warning: PHP Startup: Unable to load dynamic library 'c:/wamp64/bin/php/php5.6.25/ext/php_mongodb.dll' - Il sistema operativo non pu� eseguire %1.
in Unknown on line 0.
(for not Italian speaking, the phrase after - means the operating system can't execute %1, even if I can't imagine what %1 stands for).
Even using the new class MongoDB\Driver\Manager I get the error
Fatal error: Class 'MongoDB\Driver\Manager' not found in C:\wamp64\www\galileo\index.php on line 21
and the same warning.
Do you notice some error or forgetfulness in the installation process as I described and, if not, do you know how to fix the problem?
The problem is certainly related to WAMP and I think is related to the multiple php.ini in his folders. In fact, in the apache folder you can find a php.ini file that cannot be modified, otherwise nothing works at all; at the same time any changes made to the php.ini file in the php folder seems have no effect except making appear the mongodb extension in the extensions list.
So, I try using XAMPP, as suggested in this video tutorial and it works. Using Composer I was able to install also the PHP library and not only the driver.
you should not use 'MongoClient class' anymore, this extension that defines this class is deprecated. look at here.
instead, you should use MongoDB\Driver\Manager class. please read http://php.net/manual/en/class.mongodb-driver-manager.php.
and the setup must be like this in php:
$mongo = new MongoDB\Driver\Manager("mongodb://localhost:27017");
And if you still use the old class; you either need to install the old legacy extension (pecl install mongo) and use PHP 5.x, or update your code to use this new driver's classes as the old driver is not available for PHP 7. There is an upgrade guide at here.
the last part is from derickr's answer in this issue on github: https://github.com/mongodb/mongo-php-driver/issues/300
I am playing around with parsing spreadsheets and found the spreadsheet-reader class. I installed and have a very simple program written to open and parse an ".ODS" spreadsheet file. When I run it I get the error:
PHP Fatal error: Class 'XMLReader' not found in...
The line in question:
$ss = new SpreadsheetReader("test.ods");
So I google around and find out the version of PHP on that system needs to be at least 5.1 for it to use the version of XMLReader built into the core of PHP. I am using 5.4.12 there. I check with php -i and find PHP was compiled with: '--enable-xmlreader=shared'. According to the docs nothing needs to be configured at runtime to enable it.
Where else can I check and what am I doing wrong?
The solution is because PHP was built with a shared object file you DO need to modify php.ini: extension=xmlreader.so.
