I have a string as

```
$line = "Name=johnGender=M";

```

How to make a string called `$name` that will have a value stored as `john`.
How to extract a sub-string which is enclosed between `=` and `G` in the string $line.

OR grab a sub-string of 4 characters from the first encounter of `=` (this will work for me).

What if `$line=array("Name=john&Gender=M",Name=carl&Gender=M",);` And I wanted to put them in an array `$name` So that `$name=array("john", "carl");`
