I'm getting the error message below from a Symfony 2.8 application running PHP 7.2.8 on an Amazon Linux 2 server.
Fatal error: Uncaught RuntimeException: Extension DOM is required. in /var/www/html/my-app/vendor/symfony/symfony/src/Symfony/Component/Config/Util/XmlUtils.php:45
php-xml is installed. Other common/related libraries are installed too - php-mbstring, php-common.
In phpinfo, I cannot see the "DOM" section. Below is the screen shot of the installed php-related libraries (yum list installed | grep php*)
What am I missing here?
After 2 days of nit-picking it turned out restarting php-fpm resolves the issue, though I was restarting httpd all along.
sudo systemctl restart php-fpm
Did you verify the extension is enabled in your php.ini? Did yyou happen to install the correct version of php-xml? I had a few issues while installing PHP 7.x and installing extensions. It installed 5.6 extensions instead of 7.x when no version is specified.
Try these commands
To list all modules:
php -m
And/or to list the detailed configuration:
php -i
Check the output for the php-xml extension and if it is loaded.
I read that maybephp-mbstring has to be installed too. But i am not too sure of this, altough i usually have it installed.
In CentOS (and RHEL, i suppose) PHP module (extension) dom is provided by
php74-php-xml
https://centos.pkgs.org/7/remi-x86_64/php74-php-xml-7.4.11-1.el7.remi.x86_64.rpm.html
php74-php-dom
php74-php-domxml
php74-php-simplexml
php74-php-xml = 7.4.11-1.el7.remi
php74-php-xmlreader
php74-php-xmlwriter
php74-php-xsl

After following the install instructions for oracle instant client, php is not able to load the oci8 extension.
http://www.oracle.com/technetwork/topics/linuxx86-64soft-092277.html#ic_x64_inst
I am getting an error.
PHP Warning: PHP Startup: Unable to load dynamic library '/usr/lib/php/20151012/oci8.so' - libmql1.so: cannot open shared object file: No such file or directory in Unknown on line 0
I have verified both oci8.so and libmql1.so locations.
Am I missing something?
I'm using Ubuntu 16.04 and php version 7.1
There are few directories in /usr/lib/php/
for example
20131226 for php5.6
20160303 for php7.1
so problem with me that, the oci8 extension got installed on the wrong ( a user lib folder for php7.2) so I had to remove the php 7.2 completly
sudo apt-get purge php7.2-common
then I had uninstall the oci8 by running following command
sudo pecl uninstall oci8
and install again by running the following command
sudo pecl install oci8
To check the configuration loaded you do
php-config --extension-dir
And make sure that all extension are installed in the correct extension directory.
Make changes in the /etc/php/7.1/apache2/php.ini and /etc/php/7.1/cli/php.ini
Check by running phpinfo(); You must see this, ignore the cli if that stills gives you same error as your web shows the extension is getting loaded.
I solved adding the following to /etc/environment:
LD_LIBRARY_PATH=/opt/oracle/instantclient_12_2:$LD_LIBRARY_PATH
I followed this tutorial: https://gist.github.com/hewerthomn/81eea2935051eb2500941a9309bca703
What I did was completely remove any installations of PHP and reinstall the version that I need.
sudo apt-get purge 'php*'
Source: https://askubuntu.com/a/59889/226518
Or:
export LD_LIBRARY_PATH=/usr/local/instantclient_12_1/
I had the same problem, it works for me.
After wasting entire day for this small problem finally I came with this solution.
Sorry guys I am not champion is PHP but somehow I manage.
In my system I have CentOS 7 and PHP 7.4.XX.
I changed my LD_LIBRARY_PATH,
I have restarted my httpd service and checked phpinfo in browser (http://localhost/info.php),
Last I restared php-fpm service ........... and it's work for me.
Thanking you,

I have a Drupal site running on fresh MAMP PRO 3.0.3 install with the PHP version 5.3.28 on OS X Mavericks 10.9.2.
I installed memcache with pecl install memcache and added the extension=memcache.so line in php.iniunder the extensions section, but still Drupal shows multiple You must enable the PECL memcached or memcache extension to use memcache.inc. errors on top of the page.
phpinfo() on the Drupal root directory tells me that the configuration file loaded is at:
/Library/Application Support/appsolute/MAMP PRO/conf/php5.3.28.ini
and the extension dir is:
/Applications/MAMP/bin/php/php5.3.28/lib/php/extensions/no-debug-non-zts-20090626/
$ cat "/Library/Application Support/appsolute/MAMP PRO/conf/php5.3.28.ini" | grep memcache
extension=memcache.so
$ ls /Applications/MAMP/bin/php/php5.3.28/lib/php/extensions/no-debug-non-zts-20090626/ | grep memcache
-rwxrwxr-x 1 user admin 65K Mar 28 14:00 memcache.so*
What am I doing wrong or is this problem related to MAMP PRO 3? I've installed the memcached binaries with homebrew and the process is running.
I'm also using the Individual PHP versions for every host setting in MAMP.
When starting Apache, there is an error in the logs:
PHP Warning: PHP Startup: Unable to load dynamic library '/Applications/MAMP/bin/php/php5.3.28/lib/php/extensions/no-debug-non-zts-20090626/memcache.so' - dlopen(/Applications/MAMP/bin/php/php5.3.28/lib/php/extensions/no-debug-non-zts-20090626/memcache.so, 9): Symbol not found: _zend_new_interned_string
Referenced from: /Applications/MAMP/bin/php/php5.3.28/lib/php/extensions/no-debug-non-zts-20090626/memcache.so
Expected in: flat namespace
in /Applications/MAMP/bin/php/php5.3.28/lib/php/extensions/no-debug-non-zts-20090626/memcache.so in Unknown on line 0
What does this mean.
Thanks for your help!
I did not get the memcache extension provided by pecl to work at all. I even installed PHP 5.3.14 but encountered the same problem. Then I cloned the php-memcached-mamp repository from github and used the memcached extension from there and it worked ok.
Add intl extension to your configuration.
I just found this problem and another post that helped me fix it. macports installed php-config53 (not php-config) and I had a vagrant php-config from an old php 5.4 install. Removed /usr/bin/php-config and symlinked php=config53 -> php-config, re-rean pecl install memcache-beta and it worked.
I am trying to configure apache 2.2.15 with php5 in my linux system. I have installed both of them. But when I added libphp5.so module in httpd.conf of apache, it has given the following error while starting the server:
Starting httpd: httpd: Syntax error on line 202 of /etc/httpd/conf/httpd.conf: Cannot load /etc/httpd/modules/libphp5.so into server: /etc/httpd/modules/libphp5.so: undefined symbol: ap_unixd_config
Can anybody tell me how to fix this, as I tried every possible solution by googling it but in vain?
Some newer PHP versions may not be compatible with Apache2.2. This error occurs because the function ap_unixd_config is in Apache2.2 still called unixd_config.
Try to use Apache2.4 if you need to use this PHP version, otherwise you can use an older version of PHP.
This also happens on Arch Linux when one doesn't upgrade Apache 2.2 to Apache 2.4. So if you are using Arch Linux you need to downgrade php-apache package to the version that works for you. php-apache-5.5.8-1 is still OK, whereas 5.5.11-1 is not.
On RedHat Apache2 and PHP installation is done by issuing the following commands (as root):
yum install httpd httpd-devel php php-mysql php-common php-gd php-mbstring php-mcrypt php-devel php-xml
/etc/init.d/httpd start
That's all. (I'm following this tutorial.) You may add or remove some php extensions to or from the list of packages to be installed if so desired.
What is the best way to get PHP 5.3 up and running on CentOS 5.4.
My machine says I have PHP 5.3 installed but running into an issue with my script that says
Fatal error: Class 'PDO' not found in /var/www/html/lib/rb.php on line 45
It fails trying to new up a PDO class in the RedbeanPHP 3.0 lib.
How can I fix this missing PDO problem?
I tried to follow these instructions:
from http://www.computingunplugged.com/issues/issue201102/00002619002
rpm -Uhv http://apt.sw.be/redhat/el5/en/i386/rpmforge/RPMS/rpmforge-release-0.3.6-1.el5.rf.i386.rpm

# THIS LINE FAILED FOR ME
rpm -Uvh http://dl.iuscommunity.org/pub/ius/stable/Redhat/5/i386/ius-release-1.0-6.ius.el5.noarch.rpm
yum erase php php-pear php-mysql php-cli php-common
yum install php53u php53u-pear php53u-cli php53u-common php53u-gd
yum install php53u-mbstring php53u-mcrypt php53u-mysql php53u-soap
yum install php53u-xml php53u-xmlrpc php53u-bcmath
UPDATE
Someone removed their answer. It was good. I'm putting it back in with exact steps.
First I had to yum install php53u-devel
To quote "
You need the PDO extension. Usually the best way to install extensions is via PECL.
Before you can install any PECL extensions you need to install the php5-dev package
sudo pecl install pdo
sudo pecl install pdo_mysql
You then need add the following to the end of your php.ini file(s). Depending on which version of PHP you installed they’ll be /etc/php5/apache2/php.ini, /etc/php5/cgi/php.ini and /etc/php/cli/php.ini.
extension=pdo.so
extension=pdo_mysql.so
"
Now I get a mysql_query_missing when trying to run sudo pecl install pdo_mysql
and not sure how to get past this.
You'll have to install the php-pdo package as well.
Edit: Maybe this helps as well: How do I enable PDO using CentOS?
I have been successfully able to install PHP-5.3 on CentOS 5.4 Linux. I needed this to be able to successfully install and run Drupal 7 - which also worked out for me. Here are the details:
This is a copy of the answer I wrote up in ServerFault: https://serverfault.com/a/392168/29205
(...for my question: https://serverfault.com/questions/391772/php-xml-install-complains-of-dependency-php-common-but-this-is-already-installed/392168#392168 )
The solution is based on the accepted answer in:
https://serverfault.com/questions/391839/how-to-force-centos-yum-to-use-a-later-version-of-a-package-dependency-already-i
In summary: move to php5.3.
Reason: support for php5.2 as been removed owing to security issues as explained in that other question's accepted answer. This removal causes mismatch of the versions of the dependencies and therefore the error seen.
Background
I wanted to run Drupal 7 on a CentOS 5.4 machine. So I needed 5.3 version of PHP.
Here are the full working steps to upgrade to PHP 5.3 with working repositories as of May 24 2012 ( I provide comments preceded by # - you don't need these, just for your info)
# Comment: sites like http://www.computingunplugged.com/issues/issue201102/00002619001
# provide a good start for remedying the problem whereby we need 5.3 on CentOS 5.4 to run Drupal 7. But although their packages worked at the time, the links are now outdated, and updates to these are below.
# comment: (as of May 2012 - the following work, the reason for failures was use of 1) older packages no longer on the server and 2) change of address of one of the servers to dl.fedoraproject.org/pub/epel (credit to: http://osdir.com/ml/centos/2012-03/msg00057.html )
