push ARRAY,LIST

將一個或多個項目新增到陣列的尾端

my @animals = ("cat");
push(@animals, "mouse"); # ("cat", "mouse")

my @colors = ("red");
push(@colors, ("blue", "green")); # ("red", "blue", "green")

傳回執行 push 後陣列中的元素數量。

my $color_count = push(@colors, ("yellow", "purple"));

say "There are $color_count colors in the updated array";

從 Perl 5.14 開始,一個實驗功能允許 push 接受一個純量表達式。此實驗已被視為失敗,並在 Perl 5.24 中移除。
