arrays - PHP error suppression or isset -

-

i have array of more 50 indefinite keys means not sure 1 particular field there or not. have 2 option assign array values other.

first 

 $array2['someothefield'] = isset($array1['somefield'])?$array1['somefield']:null;

second 

 $array2['someotherfield'] = @ $array1['somefield'];

can please suggest ,which 1 better case. or, there way can suppress errors 1 block of code .

if need code fast, second option better due experience profiling php code.

if going 50 elements, use first option, because it's clear kind of problem trying avoid.

mysql - FireDac error 314 - but DLLs are in program directory -

i getting when trying access mysql database : [firedac][phys][mysql]-314. cannot load vendor library [libmysql.dll or libmysqlld.dll] this did not happen (unchanged) code, however, have upgraded windows 10 , had reinstall delphi xe8, system configuration matter. in order try solve problem, copied both of files c:\windows\sysytem32. when did not seem work, copied them \win32\debug, generated .exe resides. i imagine doing rather stupid, can't see what. the proper solution place driver file (eg., libmysql.dll ) in application's folder, or place installation location in fddrivers.ini file: [mysql] vendor=<folder>\libmysql.dll (recent versions of documentation seem use vendorlib instead of vendor in ini file.) see rad studio documentation topics configuring drivers (firedac) , connect mysql server (firedac) more information.
