php: скобки/содержимое из массива?

Question

Если у меня есть строка, как это:

$str = '[tr]Kapadokya[/tr][en]Cappadocia[/en][de]Test[/de]'; 

Я хочу, что

$array = array(
'tr' => 'Kapadokya', 
'en' => 'Cappadocia', 
'de' => 'Test'); 

Как мне это сделать?

Answer 1

С некоторыми предположениями о фактическом синтаксисе вашей строки BBCode-ish может быть достаточно (pc) regular expression.

<?php 
$str = '[tr]Kapadokya[/tr][en]Cappadocia[/en][de]Test[/de]'; 

$pattern = '! 
    \[ 
     ([^\]]+) 
    \] 
    (.+) 
    \[ 
    /
     \\1 
    \] 
!x'; 

/* alternative, probably better expression (see comments) 
$pattern = '! 
    \[   (?# pattern start with a literal [) 
     ([^\]]+) (?# is followed by one or more characters other than ] - those characters are grouped as subcapture #1, see below) 
    \]   (?# is followed by one literal ]) 
    (   (?# capture all following characters) 
     [^[]+  (?# as long as not a literal ] is encountered - there must be at least one such character) 
    ) 
    \[   (?# pattern ends with a literal [ and) 
    /   (?# literal /) 
     \1   (?# the same characters as between the opening [...] - that's subcapture #1 ) 
    \]   (?# and finally a literal ]) 
!x';  // the x modifier allows us to make the pattern easier to read because literal white spaces are ignored 
*/ 

preg_match_all($pattern, $str, $matches); 
var_export($matches);

array (
    0 => 
    array (
    0 => '[tr]Kapadokya[/tr]', 
    1 => '[en]Cappadocia[/en]', 
    2 => '[de]Test[/de]', 
), 
    1 => 
    array (
    0 => 'tr', 
    1 => 'en', 
    2 => 'de', 
), 
    2 => 
    array (
    0 => 'Kapadokya', 
    1 => 'Cappadocia', 
    2 => 'Test', 
), 
)
