PHP learning string and array conversion

In PHP learning, strings and arrays are two very important pieces of knowledge. Conversion between strings and arrays is often used in development. It is mainly implemented through the explode() function and implode() function.
1. Convert string to array.
explode(string separator, string string, [int limit]) returns an array converted from string. Each element is a substring of string, and they are separated by string separator.
If the limit parameter is set, the returned array contains up to limit elements, and the last few elements will contain the remainder of the string.
If the separator is an empty string "", the explode function will return false; if the value contained in the separator is not found in the string, the explode function will return an array of single elements of the string; if the limit is a negative number, it will return except the last All elements except -limit elements.
For example:
$str = "messi,henry,xavi";
$array = explode(",",$str);
var_dump($array);
2. Convert the array into a string
implode(string glue, array pieces)
The parameter glue is a string type, which refers to the delimiter, and the parameter pieces is the array type to be converted.
For example:
$array = array("team"=>"barcelona","name"=>"messi");
$str = implode(",",$array);
