PHP / Json String（20）之前的值

Question

I currently have some json data that I am retrieving via PHP, however, my result has String(20) in front of it;

** Answer - Var_dump causes this, just echo.

Answer 1

The string(20) is because you asked for a var_dump() of the item. var_dump() does more than echo the item, it describes it.

From the docs -

This function displays structured information about one or more expressions that includes its type and value. Arrays and objects are explored recursively with values indented to show structure.

Extra Answer - yes, try str_replace()
