PHP extract() 函數用法舉例

//匯出數組為變數 $a = 'Original'; $my_array = array("a" => "Cat","b" => "Dog", "c" => "Horse"); extract($my_array); // bbs.it-home.org echo "\$a = $a; \$b = $b; \$c = $c"; ?> 複製代碼 輸出結果：$a = Cat; $b = Dog; $c = Horse 例2，使用全部參數： $a = 'Original'; $my_array = array("a" => "Cat","b" => "Dog", "c" => "Horse"); extract($my_array, EXTR_PREFIX_SAME, 'dup'); echo "\$a = $a; \$b = $b; \$c = $c; \$dup_a = $dup_a;"; ?> 複製代碼 輸出結果：$a = Original; $b = Dog; $c = Horse; $dup_a = Cat;
