How can the error "Fatal error: Call to undefined function: preg_split()" be resolved in PHP?

The error "Fatal error: Call to undefined function: preg_split()" occurs when the preg_split() function is called but the PCRE (Perl Compatible Regular Expressions) extension is not enabled in PHP. To resolve this issue, you need to enable the PCRE extension in your PHP configuration.

// Enable the PCRE extension in PHP configuration
// This can be done by uncommenting or adding the following line in your php.ini file:
// extension=pcre.so
