i can access array value either $array[key] or $array['key'] is there reason avoid using 1 on other? use latter variant $array['key'] . former work because php tolerant , assumes string value key if there no constant named key : always use quotes around string literal array index. example, $foo['bar'] correct, while $foo[bar] not. […] wrong, works. reason […] has undefined constant ( bar ) rather string ( 'bar' - notice quotes). see array do's , don'ts . now in opposite accessing arrays in plain php code, when using variable parsing in double quoted strings need write without quotes or use curly brace syntax : […] inside double-quoted string, it's valid not surround array indexes quotes "$foo[bar]" valid. see above examples details on why section on variable parsing in strings. so: // syntax error echo "$array['key']"; // valid echo "$array[key]"; echo "{$ar...
