What are the challenges and considerations when migrating from PHP4 to PHP5 on a server without gcc installed?

When migrating from PHP4 to PHP5 on a server without gcc installed, one challenge is that you may not be able to compile certain PHP extensions that are required for PHP5. One solution is to use precompiled binaries for the necessary extensions or to find alternative solutions that do not require compilation. 

// Example code snippet using precompiled binaries for PHP5 extensions
// Assuming the extension is named "example_extension"

// Load the precompiled extension
if (!extension_loaded('example_extension')) {
    dl('path/to/precompiled_extension/example_extension.so');
}
