The explode () function of the PHP string is used

Explode

• (PHP 4, PHP 5, PHP 7)
• Explode-split a string by string
• explode-using one string to split another string

Description

arrayexplode(     $delimiter,     $string[,     $limitPHP_INT_MAX]     )//Returns an array of strings, each of which is a substring of string formed by splitting it on boundaries formed by the string delimiter.//此函数返回由字符串组成的数组，每个元素都是 string 的一个子串，它们被字符串 delimiter 作为边界点分割出来。

Parametersdelimiter

• The boundary string.
• The delimited character on the boundary.

String

• The input string.
• The input string.

Limit

• If limit is set and positive, the returned array would contain a maximum of limit elements with the last element containing The rest of the string.

• If the limit parameter is set and is a positive number, the returned array contains a maximum of limit elements, and the last element will contain the remainder of the string.

• If the limit parameter is negative, all components except the Last-limit are returned.

• If the limit parameter is a negative number, all elements except the last-limit element are returned.

• If the limit parameter is zero and then this is treated as 1.

• If limit is 0, it will be treated as 1.

Note:

• Although implode () can, for historical reasons, accept it parameters in either order, explode () cannot. You must ensure that the delimiter argument comes before the string argument.
• For historical reasons, although implode () can receive two parameter sequences, explode () does not work. You must ensure that the separator parameter is not preceded by a string parameter.

Return Values

• Returns an array of strings created by splitting the string parameter on boundaries formed by the delimiter.

• This function returns an array of strings, each of which is a substring of string, separated by the delimiter as a boundary point.

• If delimiter is an empty string (""), explode () would return FALSE. If delimiter contains a value that's not contained in string and a negative limit are used, then an empty array would be re Turned, otherwise an array containing string would be returned.

• If delimiter is an empty string (""), Explode () returns FALSE. If the value contained in the delimiter is not found in the string and a negative limit is used, then an empty array is returned, otherwise an array containing a single element of string is returned.
