PHP - 从字符串中获取子字符串

Question

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");

Answer 1

I guess the following would work for you.

$name = array();
foreach($line as $elem)
    array_push($name,substr(explode("=",$elem)[1],0,4));

So you can access it as $name[0],$name[1],...

Better try to have the input syntax as

$line = array("Name=john&Gender=M","Name=raja&Gender=M");
parse_str($line);

So you can use the built-in function parse_str().

Now $Name[0] contains john and $Name[1] contains raja.
