Question

Is there a way to do something like PHPs $array[] = 'foo';

(有没有办法像PHP一样$array[] = 'foo';)

in bash vs doing:

(在bash vs做：)

array[0] = 'foo'
array[1] = 'bar'

Yes there is:

(就在这里：)

ARRAY=()
ARRAY+=('foo')
ARRAY+=('bar')

Bash Reference Manual :

(Bash参考手册 ：)

In the context where an assignment statement is assigning a value to a shell variable or array index (see Arrays), the '+=' operator can be used to append to or add to the variable's previous value.

(在赋值语句为外壳变量或数组索引赋值的上下文中（请参见Arrays），可以使用'+ ='运算符来追加或添加到变量的先前值。)
