This article is about how to use negative limit of explode in php. The editor thinks it is very practical, so share it with you as a reference and follow the editor to have a look.

The specific analysis is as follows:

Explode-use one string to split another string into an array.

The parameters are:

Array explode (string separator, string string [, int limit])

The final limit can not be filled, then all the string will be split according to the separator separator; if limit is positive, it will be divided into (limit+1) numbers from left to right; if it is negative, limit array elements will be removed from the right (the parameter is negative, starting from php5.1), leaving the rest to form an array.

Such as:

$str= "1 2 3 4 5 6"; print_r (explode ("", $str,-2))

You will see:

Array ([0] = > 1 [1] = > 2 [2] = > 3 [3] = > 4)

It can be seen that 5 and 6 elements have been deleted.
