嘿，伙计们，我有一个字符串，看起来像这样：
b:Blue | y:Yellow | r:Red
并希望将此字符串转换为具有键值的数组。
array(
'b' => 'Blue',
'y' => 'Yellow',
'r' => 'Red'
);
我对php非常熟悉，除了爆炸的东西…
与其尝试拆分，不如匹配它：
preg_match_all('/('w):('w+)/', 'b:Blue | y:Yellow | r:Red', $matches);
print_r(array_combine($matches[1], $matches[2]));
它匹配一个字母数字字符，后面跟着一个冒号，然后是更多的字母数字字符；这两个部分都被捕获在存储器组中。最后，将第一存储器组与第二存储器组组合。
一种更受黑客攻击的方法是：
parse_str(strtr('b:Blue | y:Yellow | r:Red', ':|', '=&'), $arr);
print_r(array_map('trim', $arr));
它将字符串转换为类似application/x-www-form-urlencoded的东西，然后用parse_str()对其进行解析。之后，您需要从值中修剪任何尾随空格和前导空格。
$string = "b:Blue | y:Yellow | r:Red";
//split string at ' | '
$data = explode(" | ", $string);
$resultArray = array();
//loop through split result
foreach($data as $row) {
//split again at ':'
$result = explode(":", $row);
//add key / value pair to result array
$resultArray[$result[0]] = $result[1];
}
//print result array
print_r($resultArray);
试试这样的东西：
$str = "b:Blue | y:Yellow | r:Red";
// Split on ' | ', creating an array of the 3 colors
$split = explode(' | ', $str);
$colors = array();
foreach($split as $spl)
{
// For each color now found, split on ':' to seperate the colors.
$split2 = explode(':', $spl);
// Add to the colors array, using the letter as the index.
// (r:Red becomes 'r' => 'red')
$colors[$split2[0]] = $split2[1];
}
print_r($colors);
/*
Array
(
[b] => Blue
[y] => Yellow
[r] => Red
)
*/
首先用|爆炸，然后用：爆炸
// I got the from php.net
function multiexplode ($delimiters,$string) {
$ary = explode($delimiters[0],$string);
array_shift($delimiters);
if($delimiters != NULL) {
foreach($ary as $key => $val) {
$ary[$key] = multiexplode($delimiters, $val);
}
}
return $ary;
}
$string = "b:Blue | y:Yellow | r:Red"; // Your string
$delimiters = array(" | ", ":"); // | important that it is first
$matches = multiexplode($delimiters, $string);
/*
array (size=3)
0 =>
array (size=2)
0 => string 'b' (length=1)
1 => string 'Blue' (length=4)
1 =>
array (size=2)
0 => string 'y' (length=1)
1 => string 'Yellow' (length=6)
2 =>
array (size=2)
0 => string 'r' (length=1)
1 => string 'Red' (length=3)
