PHP extract array split into multiple variables

$size = "Old Size"; Note the value of the last size variable. $a = Array ( "Color" = "Red", "Size" = "XXL", "Price" = "53"); Extract ($a); echo "color = $color "; echo "size = $size "; echo "Price = $price "; ?> Copy Code Output: color = red Size = XXL Price = 53 The above example finds that the value of $size is XXL, not the previous "old size", which means that the original variable is overwritten by default when the key in the array conflicts with an existing variable. The following two optional arguments for the Extract function continue to be introduced. The second parameter, $extract_type, is used to control when a conflict occurs, with the possible values: $a = Array ( "Color" = "Red", "Size" = "XXL", "Price" = "53"); Extract ($a, Extr_prefix_all, "SC"); echo "color = $SC _color "; echo "size = $SC _size "; echo "Price = $SC _price "; Extract ($a, extr_refs); $color = "green"; echo $a [' color ']; View the values of the original array ?> Copy Code Output: color = red Size = XXL Price = $ green
