Error: Unable to Load Dynamic Libraries in PHP5
While attempting to execute PHP commands, you may encounter an error message indicating that dynamic libraries cannot be loaded. This error can occur when PHP is unable to locate or open shared object (.so) files for certain extensions.
Root Cause:
Based on the error messages you provided, PHP5 is attempting to load the following extensions, but the corresponding .so files are missing:
- curl
- mcrypt
- mysql
- mysqli
- pdo
- pdo_mysql
Solution:
Instead of installing additional software unnecessarily, it's recommended to address the underlying issue by disabling the loading of these extensions that can't be found.
Step 1: Identify Loading Files
Use the following command to identify the files that are trying to load the problematic extensions:
<code class="bash">$ grep -Hrv ";" /etc/php5 | grep -E "extension(\s+)?="</code>
Step 2: Disable Extension Loading
Once you have the list of files, locate the sections where the following extensions are being loaded:
extension=curl.so extension=mcrypt.so extension=mysql.so extension=mysqli.so extension=pdo.so extension=pdo_mysql.so
Comment out these lines by adding a ; at the beginning.
Example:
;extension=curl.so ;extension=mcrypt.so
Additional Considerations:
- The specific file locations may vary depending on your operating system and PHP installation.
- If the error persists after disabling the extensions, ensure that the corresponding shared object files are installed and in the correct path.
