In PHP, the regular expression is converted into a lower-case underline variable and the variable is changed to a camper type $ methodset. preg_replace (& nbsp ;(? : ^ | _) ([A-z]) e, & nbsp; & nbsp; & regular expression in PHP converts lower-case underline variable to hump type
$ Method = 'set'. preg_replace (
"/(? : ^ | _) ([A-z])/e ",
"Strtoupper ('\ 1 ')",
$ F );

For example, first_name-> setFirstName
Click_url-> setClickUrl

The/e in the regular expression can be executed. This feature also exists in perl.

If it cannot be executed
B-> B
Z-> Z
I don't know if there is any other way.
