Great — TEST build success ✅
Now we have exactly what we need:

• imagewebp() = true
• GD WebP Support = 1

So your server can run PHP 8.2.12 with GD+WebP.
Next step is to put this into XAMPP (/opt/lampp) safely.

Below is the production-safe swap plan with rollback.

Step A — Take a full backup of current XAMPP PHP

TS="$(date +%F-%H%M)"
sudo mkdir -p /root/xampp-php-backup-$TS

sudo cp -a /opt/lampp/bin/php /root/xampp-php-backup-$TS/
sudo cp -a /opt/lampp/bin/phpize* /root/xampp-php-backup-$TS/ 2>/dev/null || true
sudo cp -a /opt/lampp/bin/php-config* /root/xampp-php-backup-$TS/ 2>/dev/null || true
sudo cp -a /opt/lampp/modules/libphp*.so /root/xampp-php-backup-$TS/ 2>/dev/null || true
sudo cp -a /opt/lampp/etc/php.ini /root/xampp-php-backup-$TS/
sudo cp -a /opt/lampp/lib/php/extensions/no-debug-non-zts-20220829 /root/xampp-php-backup-$TS/extensions-20220829 2>/dev/null || true

echo "Backup saved at /root/xampp-php-backup-$TS"

Step B — Reconfigure PHP 8.2.12 for XAMPP (/opt/lampp) WITH WebP

Now we rebuild from the same source directory but install into /opt/lampp.

cd /usr/local/src/php-8.2.12

make distclean 2>/dev/null || true
rm -f config.cache

export PKG_CONFIG_PATH="/usr/lib/x86_64-linux-gnu/pkgconfig:/usr/share/pkgconfig:/opt/lampp/lib/pkgconfig"
unset CPPFLAGS
unset LDFLAGS

✅ Makefile check:

ls -l Makefile

Build + install:

make -j"$(nproc)"
sudo make install

Restart XAMPP:

sudo /opt/lampp/lampp restart

Step C — Verify XAMPP PHP now has WebP

/opt/lampp/bin/php -r 'var_dump(function_exists("imagewebp"));'
/opt/lampp/bin/php -r 'print_r(gd_info());' | grep -i webp

Expected:

• bool(true)
• WebP Support => 1

Step D — Verify Eventmie error is gone

Now your /admin/settings/update WebP encode will work.

Also clear Laravel caches:

cd /opt/lampp/htdocs/lucknoworbit.com
/opt/lampp/bin/php artisan optimize:clear

Instant Rollback (if anything breaks)

BK="$(ls -dt /root/xampp-php-backup-* | head -n 1)"
sudo cp -a "$BK/php" /opt/lampp/bin/php
sudo cp -a "$BK/php.ini" /opt/lampp/etc/php.ini
sudo cp -a "$BK"/libphp*.so /opt/lampp/modules/ 2>/dev/null || true
sudo /opt/lampp/lampp restart
echo "Rolled back from $BK"
