Line and colon separated list to array PHP

问题

I'm trying to work out a simple way to take a list, like this

foo: Alpha
bar: Bravo
fooBar: Charlie

And turn this into an associative array so that values would be

$array['foo'] //would contain Alpha
$array['bar'] //would contain Bravo

etc.

What is the cleanest way to achieve this ?

回答1:

Something like this?:

$string = "foo: Alpha
bar: Bravo
fooBar: Charlie";

$array = array();
$lines = explode("\n", $string);

foreach ($lines as $line) {
    list($key, $value) = explode(": ", $line);
    $array[$key] = $value;
}

var_dump($array);

Result:

array(3) {
  ["foo"]=>
  string(6) "Alpha
"
  ["bar"]=>
  string(6) "Bravo
"
  ["fooBar"]=>
  string(7) "Charlie"
}

You can do it manually if your first list is already in an array:

$array = [];
$list = ['foo: Alpha', 'bar: Bravo'];

foreach ($list as $element) {
    $parts = explode(': ', $element);
    $array[$parts[0]] = $parts[1];
}

Otherwise, simply use parse_ini_string to parse a string that contains your data into an associative array (note that this function requires PHP 5.3 or greater).

If your data is in a string, and you don't have PHP 5.3, you can split on new lines to get an array: $list = explode("\n", $string);.

Try this : $array = array();

$str    = 'foo: Alpha';
$res    = explode(":",$str);
$array[$res[0]] = $res[0];

Maybe this is overkill but if your file format is likely to expand, it's worth looking into YAML, your example happens to be valid YAML markup. So you could for example use the Symfony YAML component

use Symfony\Component\Yaml\Yaml;
$array = Yaml::parse('/path/to/file.yml');

It works with your current format and if you decide to add nested arrays or other non-trivial data, just use the YAML syntax, which is quite intuitive. Here is an introduction to the format: http://symfony.com/doc/2.0/components/yaml/yaml_format.html
