我真的不知道正则表达式...
所以我被卡住了......任何人都可以给我一个解释正则表达式本身的解决方案吗？
这是我的代码:
$str = "id:521082299088|name:JOHNSON GREIG DENOIA|mounth:JAN17|amount:170027|admin:2500|billqty:1|metre:R1/900|usage:00010261-00010550|reffno:0BKP21851AF3EC2E0D4F56997EA19DFA|charge:170377|balace:1935";
$pregsplit = preg_split("/[\s|]+/",$string2);
输出:
Array
(
[0] => id:521082299088
[1] => name:JOHNSON
[2] => GREIG
[3] => DENOIA
[4] => mounth:JAN17
[5] => amount:170027
[6] => admin:2500
[7] => billqty:1
[8] => metre:R1/900
[9] => usage:00010261-00010550
[10] => reffno:0BKP21851AF3EC2E0D4F56997EA19DFA
[11] => charge:170377
[12] => balance:1935
)
我想要这样的输出:
Array
(
"id" => 521082299088
"name" => "JOHNSON GREIG DENOIA"
"mount" => "JAN17"
"amount" => 170027
"admin" => 2500
"billqty" => 1
"metre" => "R1/900"
"usage" => "00010261-00010550"
"reffno" => "0BKP21851AF3EC2E0D4F56997EA19DFA"
"charge" => 170377
"balance" => 1935
)
1) 使用具有特定正则表达式模式的 preg_match_all 函数的解决方案:
$str = "id:521082299088|name:JOHNSON GREIG DENOIA|mounth:JAN17|amount:170027|admin:2500|billqty:1|metre:R1/900|usage:00010261-00010550|reffno:0BKP21851AF3EC2E0D4F56997EA19DFA|charge:170377|balace:1935";
preg_match_all("/(\w+):([^|]+)/", $str, $matches, PREG_SET_ORDER);
$result = [];
foreach ($matches as $items) {
$result[$items[1]] = $items[2];
}
// $items[1] contains a "parameter" name captured by the first capturing group (\w+)
// $items[2] contains a "parameter" value captured by the second capturing group ([^|]+)
print_r($result);
输出:
Array
(
[id] => 521082299088
[name] => JOHNSON GREIG DENOIA
[mounth] => JAN17
[amount] => 170027
[admin] => 2500
[billqty] => 1
[metre] => R1/900
[usage] => 00010261-00010550
[reffno] => 0BKP21851AF3EC2E0D4F56997EA19DFA
[charge] => 170377
[balace] => 1935
)
(\w+) - 匹配后跟 :
的所有字母数字字符
([^|]+) - 匹配除分隔符 | 之外的所有字符

2) 除了第一种方法 - 使用 array_combine 函数(合并来自两个捕获组的所有相应值):
preg_match_all("/(\w+):([^|]+)/", $str, $matches);
$result = array_combine($matches[1], $matches[2]);
// will give the same result
3) 第三种替代方法是使用 explode() 函数:
$result = [];
foreach (explode("|", $str) as $items) {
$pair = explode(":", $items);
$result[$pair[0]] = $pair[1];
}
