Php7 converts strings to arrays

Method 1: use the str_split () function

The str_split () function splits the string into an array according to the specified length, in grammatical format:

Str_split (string,length)

String is required. Specifies the string to be split.

Length is optional. Specifies the length of each array element. The default is 1.

The function FALSE will be returned if length is less than 1. If the length is greater than the length of the string, the entire string is returned as the only element of the array.

Method 2: use the explode () function

The explode () function splits a string into parts with specific delimiters.

The explode () function splits a string based on a string delimiter, that is, it splits a string into several substrings based on the delimiter, and then combines these substrings into an array and returns. The syntax format is as follows:

Explode (separator,string,limit)

The parameters are described as follows:

Separator: delimited characters used to split strings

String: a string that needs to be split

Limit: optional parameter, which can be empty, specifying the number of array elements to be returned

If $limit is not empty and is positive, the returned array contains at most $limit elements, and the last element contains the rest of $string

If $limit is not empty and is negative, all elements except the last $limit element are returned

If $limit is 0, it will be treated as 1

If $limit is empty, all array elements are returned.

Example:

Method 3: cast-cast the variable type (array) by adding the target type in parentheses before the variable
