Как разбирать строку в массиве

Question

У меня следующее значение в столбце таблицы есть ли опция для получения значения sandbox и merchant_email как массив? Я знаю, что использование explode и loop работает, но любые другие интеллектуальные опции ? что-то вроде $result->sandbox

paypal_merchant_email="sample@ymail.com"|paypal_verified_only="0"|payment_currency=""|sandbox="1"|sandbox_merchant_email="sample@ymail.com"|payment_logos=""|debug="0"|status_pending="W"|status_success="O"|status_canceled="D"|countries=""|min_amount="0"|max_amount="0"|secure_post=""|ipn_test=""|no_shipping="0"|address_override="0"|cost_per_transaction="0"|cost_percent_total="0"|tax_id=0| 

Заранее спасибо!

Маленький тест магии:

<?php 
// explode 
$start = microtime(TRUE); 
$data = array(); 
foreach (explode('|', $result->sandbox) as $item) 
{ 
    if (empty($item)) continue; 
    list($key, $value) = explode("=", $item); 
    $data[$key] = str_replace('"', '', $value); 
} 
print_r($data); 
$stop = microtime(TRUE); 
$timeResult = $stop - $start; 
echo $timeResult, "\n"; 

//preg_split 
$start = microtime(TRUE); 
$data = array(); 
foreach (preg_split('/\|/', $result->sandbox) as $item) 
{ 
    if (empty($item)) continue; 
    list($key, $value) = preg_split('/=/', $item); 
    $data[$key] = str_replace('"', '', $value); 
} 
print_r($data); 
$stop = microtime(TRUE); 
$timeResult = $stop - $start; 
echo $timeResult, "\n"; 

//preg_match_all 
$start = microtime(TRUE); 
$data = array(); 
preg_match_all('/([^=]+)="([^"]+)?"\|/', $result->sandbox, $result); 
$data = array_combine($result[1], $result[2]); 
print_r($data); 
$stop = microtime(TRUE); 
$timeResult = $stop - $start; 
echo $timeResult, "\n"; 

Результат:

$string = 'paypal_merchant_email="sample@ymail.com"|paypal_verified_only="0"|payment_currency=""|sandbox="1"|sandbox_merchant_email="sample@ymail.com"|payment_logos=""|debug="0"|status_pending="W"|status_success="O"|status_canceled="D"|countries=""|min_amount="0"|max_amount="0"|secure_post=""|ipn_test=""|no_shipping="0"|address_override="0"|cost_per_transaction="0"|cost_percent_total="0"|tax_id=0|'; 

$result = array(); 
$string = preg_split('/\|/', $string); 
foreach($string as $key => $value) 
{ 
    $value = str_replace('"', '', $value); 
    $value = preg_split('/=/', $value); 
    if(strlen($value[0])> 0) 
    { 
     $result[$value[0]] = array_key_exists(1, $value) ? $value[1] : NULL;

Существует функция parse_str(), но это для & разделителем: http://php.net/manual/en/function.parse-str.php

Или вы можете произвести впечатление на кого-то со знанием или PHP функций:

$str = 'a=13|b="string"|'; 

$rawarray = preg_split('/\|/', $str, -1, PREG_SPLIT_NO_EMPTY); 
$keys = array_map(create_function('$a', '$r = preg_split("/=/", $a); return $r[0];'), $rawarray); 
$values = array_map(create_function('$a', '$r = preg_split("/=/", $a, 2); return eval("return $r[1];");'), $rawarray); 
$result = array_combine($keys, $values); 

print_r($result); 

Answer 4

Если вам нужно только один или два значения, использовать регулярные выражения:

function get_value_from_string($key, $str) { 
    return preg_match('/\|'.$key.'=([^\|]*)/', '|'.$str, $matches) ? eval("return $matches[1];") : null; 
} 

Answer 5

Вот вам более элегантное решение с использованием str_getcsv, array_walk, use, parse_str и почтенного each (для извлечения пар ключ/значение). С вашими данными:

$string = 'paypal_merchant_email="sample@ymail.com"|paypal_verified_only="0"|payment_currency=""|sandbox="1"|sandbox_merchant_email="sample@ymail.com"|payment_logos=""|debug="0"|status_pending="W"|status_success="O"|status_canceled="D"|countries=""|min_amount="0"|max_amount="0"|secure_post=""|ipn_test=""|no_shipping="0"|address_override="0"|cost_per_transaction="0"|cost_percent_total="0"|tax_id=0|'; 

Идея заключается в использовании первого str_getcsv разобрать | -разделенное линию, затем траверс его, используя быстрые функции PHP.

$t = str_getcsv($string, "|"); 

В этот момент $ t представляет собой простой массив, содержащий разбитые пары «ключ = значение».

$new = array(); 
array_walk($t, function(&$a) use (&$new) { 
    parse_str($a, $b);   # parses each line, returns key-value 
    $c = each($b);    # need to obtain key-value from above 
    $new[$c["key"]] = $c["value"]; # simple assignment 
}); 

Для этого требуется PHP> 5.3.0, поскольку он использует пространства имен (использование) в анонимной функции. Однако, если вы сделали это далеко, print_r($new); дает вам следующее:

Array (
    [paypal_merchant_email] => "sample@ymail.com" 
    [paypal_verified_only] => "0" 
    [payment_currency] => "" 
    ... 

Answer 6

Здесь очень компактное решение для Вас:

preg_match_all('/\|(.*?)="(.*?)"/', '|'.$string, $matches); 
$result = array_combine($matches[1], $matches[2]);
