I am using Ubuntu 14.04 LTS and PHP v5.6

There are other versions on the same computer php5 and php7 , but php5.6 included. I tried installing cURL with

 sudo apt-get install php5.6-curl 

Now i get

Unable to load curl.so dynamic library

After starting php -i | grep ini php -i | grep ini i get the following

 root@ubuntu :/etc/php/5.6/apache2# php -i | grep ini PHP Warning: PHP Startup: Unable to load dynamic library '/usr/lib/php/20131226/curl.so' - /usr/lib/php/20131226/curl.so: undefined symbol: zend_unset_property in Unknown on line 0 Configuration File (php.ini) Path => /etc/php/5.6/cli Loaded Configuration File => /etc/php/5.6/cli/php.ini Scan this dir for additional .ini files => /etc/php/5.6/cli/conf.d Additional .ini files parsed => /etc/php/5.6/cli/conf.d/10-mysqlnd.ini, /etc/php/5.6/cli/conf.d/10-opcache.ini, /etc/php/5.6/cli/conf.d/10-pdo.ini, /etc/php/5.6/cli/conf.d/15-xml.ini, /etc/php/5.6/cli/conf.d/20-calendar.ini, /etc/php/5.6/cli/conf.d/20-ctype.ini, /etc/php/5.6/cli/conf.d/20-curl.ini, /etc/php/5.6/cli/conf.d/20-dom.ini, /etc/php/5.6/cli/conf.d/20-exif.ini, /etc/php/5.6/cli/conf.d/20-fileinfo.ini, /etc/php/5.6/cli/conf.d/20-ftp.ini, /etc/php/5.6/cli/conf.d/20-gettext.ini, /etc/php/5.6/cli/conf.d/20-iconv.ini, /etc/php/5.6/cli/conf.d/20-json.ini, /etc/php/5.6/cli/conf.d/20-mbstring.ini, /etc/php/5.6/cli/conf.d/20-mysql.ini, /etc/php/5.6/cli/conf.d/20-mysqli.ini, /etc/php/5.6/cli/conf.d/20-pdo_mysql.ini, /etc/php/5.6/cli/conf.d/20-phar.ini, /etc/php/5.6/cli/conf.d/20-posix.ini, /etc/php/5.6/cli/conf.d/20-readline.ini, /etc/php/5.6/cli/conf.d/20-shmop.ini, /etc/php/5.6/cli/conf.d/20-simplexml.ini, /etc/php/5.6/cli/conf.d/20-sockets.ini, /etc/php/5.6/cli/conf.d/20-sysvmsg.ini, /etc/php/5.6/cli/conf.d/20-sysvsem.ini, /etc/php/5.6/cli/conf.d/20-sysvshm.ini, /etc/php/5.6/cli/conf.d/20-tokenizer.ini, /etc/php/5.6/cli/conf.d/20-wddx.ini, /etc/php/5.6/cli/conf.d/20-xmlreader.ini, /etc/php/5.6/cli/conf.d/20-xmlwriter.ini, /etc/php/5.6/cli/conf.d/20-xsl.ini user_ini.cache_ttl => 300 => 300 user_ini.filename => .user.ini => .user.ini init_command_executed_count => 0 init_command_failed_count => 0 com_init_db => 0 Classes => AppendIterator, ArrayIterator, ArrayObject, BadFunctionCallException, BadMethodCallException, CachingIterator, CallbackFilterIterator, DirectoryIterator, DomainException, EmptyIterator, FilesystemIterator, FilterIterator, GlobIterator, InfiniteIterator, InvalidArgumentException, IteratorIterator, LengthException, LimitIterator, LogicException, MultipleIterator, NoRewindIterator, OutOfBoundsException, OutOfRangeException, OverflowException, ParentIterator, RangeException, RecursiveArrayIterator, RecursiveCachingIterator, RecursiveCallbackFilterIterator, RecursiveDirectoryIterator, RecursiveFilterIterator, RecursiveIteratorIterator, RecursiveRegexIterator, RecursiveTreeIterator, RegexIterator, RuntimeException, SplDoublyLinkedList, SplFileInfo, SplFileObject, SplFixedArray, SplHeap, SplMinHeap, SplMaxHeap, SplObjectStorage, SplPriorityQueue, SplQueue, SplStack, SplTempFileObject, UnderflowException, UnexpectedValueException 

And this is the actual warning

PHP Warning: starting PHP: cannot load dynamic library '/usr/lib/php/20131226/curl.so' - / usr / lib / php / 20131226 / curl.so: undefined character: zend_unset_property in Unknown in line 0

It is also verified that cURL is not working. Any help is much appreciated.

Answer 1

Update php5.6 (-common) to a newer version. This can be done using apt-get update && apt-get upgrade . You just upgraded php5.6-curl to the latest version, but it depends on the new php5.6.

Answer 2

Same problem on php7. Just did apt-get dist-upgrade , and now the warning has disappeared, and the curl is working correctly. Hope this helps!
