PHP Remove all non-keyboard characters from string.
preg_replace('/[^(x20-x7F)]*/','', $text);
In the above function, "
/[^(x20-x7F)]*/" is used to identify the non keyboard characters.
For Ex:
$text="GvÄÖÜSubhÂÂu"; //ÄÖÜ and ÂÂ are the non keyboard char. we need to remove it.
echo preg_replace('/[^(x20-x7F)]*/','', $text);
Output is : GvSubhu .
and you can replace any char instead of non keyboard char, like,
echo preg_replace('/[^(x20-x7F)]*/','-', $text);
It will return : Gv-Subh-u .
