Mt_rand () function, Str_shuffle () function, join () function

Mt_rand () returns a random integer using the Mersenne Twister algorithm.

Grammar

Mt_rand (Min,max)

Definition and usage

The Str_shuffle () function randomly scrambles all characters in a string.

Grammar

Str_shuffle (String)

The Array_merge () function merges two or more arrays into an array.

Definition and usage

The join () function combines array elements into a single string.

The join () function is an alias for the implode () function.

Grammar

Join (Separator,array)

Definition and usage

The Array_merge () function merges two or more arrays into an array.

If the key name is duplicated, the key's key value is the value corresponding to the last key name (followed by overwriting the previous one). If the array is a numeric index, the key name is re-indexed in a sequential manner.

Note: If you only enter an array into the Array_merge () function and the key name is an integer, the function returns a new array with an integer key name, with the key name re-indexed starting at 0. (see Example 2)
