Trim all array elements with PHP:

$trimmed_array = array_map('trim', $fruits);

To see the difference:

WGET do:

1. Download example.com
2. Download all level-1 and level-2 links
3. Download everything to : /root/t3mp/wget
4. Identify as 'Mozilla/MyUserAgent'
5. Ignore robots.txt
6. Random wait between requests (average : 3 seconds)

wget -U 'Mozilla/MyUserAgent' -P /root/t3mp/wget --wait=3 --random-wait -nd -r -l 2 -e robots=off https://example.com

Mysql export kann sehr lange dauert, wenn man viele und große Datenbanken hat. Damit man schnell ein Backup von allen DBs erstellen kann:

mysqldump --opt --quick --all-databases > /root/backup/mysql/alldbs.sql
  
  

Wenn User login notwendig ist :

mysqldump -u root -p --opt --quick --all-databases > /root/backup/mysql/alldbs.sql
