如何根据需要ccondition

Question

我想在字符串中的数组拆分和值存储在表中，以阵列的字符串分割 的字符串是

$string="34=No,46=fgbfb,48=NA,29=NA,45=dsd,49=InConclusive,43=1BHK,35=NA,38=12,39=2,27=q1,41=Others,52=fgfdg,47=fgfg,31=Chawl,33=UpperMiddleClass,37=SelfOwned,30=fdgfdgb,50=fgfdgb,51=fgfdg,32=NA,44=[Refrigerator,Airconditioner]"; 

我试过爆炸（“”，$串）; 但我不想要分割对象阵列，即（44 = [冰箱，空调器]）此我要像44和冰箱，空调器

预期结果： -

Array ( 
     [0] => 34=No 
     [1] => 46=fgbfb 
     [2] => 48=NA 
     [3] => 29=NA 
     [4] => 45=dsd 
     [5] => 49=InConclusive 
     [6] => 43=1BHK 
     [7] => 35=NA 
     [8] => 38=12 
     [9] => 39=2 
     [10] => 27=q1 
     [11] => 41=Others 
     [12] => 52=fgfdg 
     [13] => 47=fgfg 
     [14] => 31=Chawl 
     [15] => 33=UpperMiddleClass 
     [16] => 37=SelfOwned 
     [17] => 30=fdgfdgb 
     [18] => 50=fgfdgb 
     [19] => 51=fgfdg 
     [20] => 32=NA 
     [21] => 44=[Refrigerator,Airconditioner] 
    ) 

Answer 1

解其工作在所有可能的情况： -

<?php 
$string="34=No,46=fgbfb,48=NA,29=NA,45=dsd,49=InConclusive,43=1BHK,35=NA,38=12,39=2,27=q1,41=Others,52=fgfdg,47=fgfg,31=Chawl,33=UpperMiddleClass,37=SelfOwned,30=fdgfdgb,50=fgfdgb,51=fgfdg,32=NA,44=[Refrigerator,Airconditioner]"; 

$string = str_replace(["[","]"], ["{","}"], $string); // convert `[` to `{` and `]` to `}` 
$array = preg_split('/(,)(?=(?:[^}]|{[^{]*})*$)/',$string); // split string by `,` and ignore `,` between `{}` 
echo "<pre/>";print_r($array); // print array 
foreach ($array as &$ar){ // iterate through array 
    $ar = str_replace(["{","}"], ["[","]"], $ar); // convert `{` to `[` and `}` to `]` 

} 

echo "<pre/>";print_r($array); // print desired array

Answer 2

只要使用适当的正则表达式与preg_match_all：

/\d+=(?:\[[^]]*]|[^,]*)/ 

见regex demo。

详细：

• \d+ - 1+位数
• = - 一个=
• (?:\[[^]]*]|[^,]*) - 无论是2个备选方案：
  • \[[^]]*] - 一个[随后与0+除]和t之外的字符母鸡]
  • | - 或
  • [^,]* - 0+字符比,其他。

如果阵列可以嵌套[...]里面，你就需要使用一些更复杂的正则表达式（demo）：

/\d+=(?:(\[(?:[^][]++|(?1))*])|[^,]*)/ 

见PHP demo：

$string="34=No,46=fgbfb,48=NA,29=NA,45=dsd,49=InConclusive,43=1BHK,35=NA,38=12,39=2,27=q1,41=Others,52=fgfdg,47=fgfg,31=Chawl,33=UpperMiddleClass,37=SelfOwned,30=fdgfdgb,50=fgfdgb,51=fgfdg,32=NA,44=[Refrigerator,Airconditioner]"; 
preg_match_all('~\d+=(?:\[[^]]*]|[^,]*)~', $string, $results); 
print_r($results[0]);
