use php functions as function argument -

-

can call php function in custom function argument.

example

function customfunction(trim($args),addslashes($args_second)) {     //other code }

that gave parse error: syntax error, unexpected '(', expecting '&' or t_variable error. correct way.?

i know can inside function why can not way.?

what trying impossible php.

information may passed functions via argument list, comma-delimited list of expressions. arguments evaluated left right.

php supports passing arguments value (the default), passing reference, , default argument values. variable-length argument lists supported.

i getting getbluetoothservice() called no bluetoothmanagercallback error in android application. i have no idea causing or bluetooth manager callbacks. can give me idea of causing problem or start looking. by reading android source code, seems warning cannot about. source code shows if call bluetoothsocket#connect(); then call bluetoothadapter.getdefaultadapter().getbluetoothservice(null); the key here, null parameter passes in above line. due this, there no callback, , bluetoothsocket class throw out warning. since warning, not think need it. https://android.googlesource.com/platform/frameworks/base/+/master/core/java/android/bluetooth/bluetoothsocket.java line 306 https://android.googlesource.com/platform/frameworks/base/+/master/core/java/android/bluetooth/bluetoothadapter.java line 1610
