Question

我有像这样的字符串

selectedvalue == product || product condition || product flush then @"yes,no",selectedvalue == water || water condition || water flush then @"true,false"。

在preg split中使用一些模式以获得数组中的结果输出。

Array(
 0 => selectedvalue == product || product condition || product flush then @"yes,no"
 1 => selectedvalue == water || water condition || water flush then @"true,false"
);

任何人都可以帮忙吗？

Answer 1

<?php

$data='selectedvalue == product || product condition || product flush then @"yes,no",selectedvalue == water || water condition || water flush then @"true,false"';


$data=explode('selectedvalue',$data);

$myArray=[];
foreach($data as $row){
    $myArray[]='selectedvalue '.$row;
}

echo '<pre>';
unset($myArray[0]);
print_r($myArray);

您可以尝试使用explode来创建数组。这就是为此功能创建的。

上述代码的输出是：

Array
(
    [1] => selectedvalue  == product || product condition || product flush then @"yes,no",
    [2] => selectedvalue  == water || water condition || water flush then @"true,false"
)

这是一个“肮脏”的解决方案，但我认为它将解决您的问题。如果您可以使用管道拆分记录会更好，您可以简单地爆炸到管道分隔符并准备好阵列。

如果您必须使用preg_split来获取结果，则可以使用正向前瞻(?=selectedvalue)来匹配逗号，以断言后面的内容为selectedvalue：

$pattern = "/,(?=selectedvalue)/";
$string = 'selectedvalue == product || product condition || product flush then @"yes,no",selectedvalue == water || water condition || water flush then @"true,false';
var_dump(preg_split($pattern, $string));

那会给你：

array(2) {
  [0]=>
  string(77) "selectedvalue == product || product condition || product flush then @"yes,no""
  [1]=>
  string(74) "selectedvalue == water || water condition || water flush then @"true,false"
}

拆分字符串与preg_split php
