I just finished writing a program written in PHP today. When I moved to the another environment, I found that the script didn’t work. After some investigations, I found that the program stopped running because of the following error:<\/p>\n
<\/div>\n
\r\nPHP Fatal error: Class 'ZipArchive' not found in ...\r\n<\/pre>\nThe error is obvious, some PHP extensions were missing. Therefore, I ran the following to see which modules were being loaded by the php:<\/p>\n
\r\n#Make sure that the php is living in \/opt\/lampp\/\r\n#which php\r\n\/opt\/lampp\/bin\/php\r\n\r\n#php -m\r\n[PHP Modules]\r\n...\r\n...\r\nxsl\r\nzlib\r\n<\/pre>\nOkay, the problem is clear, zip<\/strong> is missing.<\/p>\nFor some (stupid) reasons, XAMPP (1.8.1) removes the zip support from the package. I don’t understand why because it was available in the older version (1.7.3). Removing a popular package will create troubles and backward compatibility issues. Anyway, the XAMPP is a non-professional product. It is not designed for production uses.<\/p>\n
Before we go further, please make sure that your PHP is 5.4.7. It is because this tutorial is version specific.<\/p>\n
\r\n#php -v\r\n\r\nPHP 5.4.7\r\n<\/pre>\nHere are the details:<\/p>\n
\r\n#As always, we want to switch to root user first\r\nsudo su\r\n\r\n#Switch to the extension directory\r\ncd \/opt\/lampp\/lib\/php\/extensions\/no-debug-non-zts-20100525\r\n\r\n#Download the missing zip.so\r\n#This zip.so was extracted from a 32-bit Linux environment, and was complied using PHP 5.4.7 32-bit i686\r\n#It will not work with a different PHP version.\r\nwget http:\/\/icesquare.com\/download\/zip.so\r\n\r\n#Modify the permissions\r\nchmod a+x zip.so\r\nchown root:root zip.so\r\n<\/pre>\nNow, we will need to modify the php.ini<\/p>\n
\r\n#nano \/opt\/lampp\/etc\/php.ini\r\n\r\n#Look for the zip.so and remove the comment\r\n\r\n#From\r\n;extension=\"zip.so\"\r\n\r\n#To\r\nextension=\"zip.so\"\r\n<\/pre>\nNext, we will need to verify that the extension is being loaded by php:<\/p>\n
\r\n#php -m\r\n[PHP Modules]\r\n...\r\n...\r\nxsl\r\nzip < ------------ This one\r\nzlib\r\n<\/pre>\nIf everything looks good, we will need to restart the apache.<\/p>\n
\r\n#\/opt\/lampp\/lampp reloadapache\r\n<\/pre>\nThat’s it! Now the error is gone. You can also verify it by including phpinfo() in your code. It should display the details about the zip package.<\/p>\n
My last word: Stay away from XAMPP when possible. It is using 32-bit stone-age technology, full of security-related bugs (because they release one or two versions ever year), and is packaged in a very non-professional way (such as backward compatibility). Consider to move to native Apache + PHP + MySQL. Believe me, you will see at least 10% of the performance improvement.<\/p>\n
