In PHP, the array value has double quotes. This is because the value is of string type. For example,
array(1,2,3,4,"5",6,7,"8",9)

Step 2: In the loop body, convert the string type array to other types
Use the is_string() function to determine the array elements Whether $value is a string type
If so, use the settype() function to set the element to another type
if(is_string($value)){ settype($value,"指定类型"); }
Complete implementation Code:
