如何在PHP中拆分此字符串？

我有一个字符串如下所示：

'word','another word','and a sentence','and more','etc etc'

        <?php

                 $string = "'word','another word','and a sentence','and more','etc etc'";
                 $pattern = '%\',\'%';
                 $split = preg_split($pattern,$string);
                 $array1 = array();
                 $array2 = array();
                 foreach($split as $key=>$value)
                 {
                    $value  = trim($value,"'");
                    $value = "'{$value}'";

                    if(($key === 0) || ($key ===1))
                    {
                        $array1[] = $value;
                    }
                    else
                    {
                        $array2[] = $value; 
                    }
                 }

                echo $req_string1 = implode(',',$array1);
                echo "<br>";
                echo $req_string2 = implode(',',$array2);     


             ?>

我需要把它分成两个字符串，除以第二个逗号，这两个句子都不应该出现。使事情复杂化的是，在字符串的各个引号部分中也可以有逗号

        <?php

                 $string = "'word','another word','and a sentence','and more','etc etc'";
                 $pattern = '%\',\'%';
                 $split = preg_split($pattern,$string);
                 $array1 = array();
                 $array2 = array();
                 foreach($split as $key=>$value)
                 {
                    $value  = trim($value,"'");
                    $value = "'{$value}'";

                    if(($key === 0) || ($key ===1))
                    {
                        $array1[] = $value;
                    }
                    else
                    {
                        $array2[] = $value; 
                    }
                 }

                echo $req_string1 = implode(',',$array1);
                echo "<br>";
                echo $req_string2 = implode(',',$array2);     


             ?>

有人能帮我吗？

这很像CSV语法，所以：

$parsed  = str_getcsv($string, ',', "'");
$string1 = join(',', array_slice($parsed, 0, 2));
$string2 = join(',', array_slice($parsed, 2));

        <?php

                 $string = "'word','another word','and a sentence','and more','etc etc'";
                 $pattern = '%\',\'%';
                 $split = preg_split($pattern,$string);
                 $array1 = array();
                 $array2 = array();
                 foreach($split as $key=>$value)
                 {
                    $value  = trim($value,"'");
                    $value = "'{$value}'";

                    if(($key === 0) || ($key ===1))
                    {
                        $array1[] = $value;
                    }
                    else
                    {
                        $array2[] = $value; 
                    }
                 }

                echo $req_string1 = implode(',',$array1);
                echo "<br>";
                echo $req_string2 = implode(',',$array2);     


             ?>

如果您的PHP版本低于5.3，因此您没有，您可以使用虚拟文件句柄将其复制到

php://temp

和

fgetcsv

        <?php

                 $string = "'word','another word','and a sentence','and more','etc etc'";
                 $pattern = '%\',\'%';
                 $split = preg_split($pattern,$string);
                 $array1 = array();
                 $array2 = array();
                 foreach($split as $key=>$value)
                 {
                    $value  = trim($value,"'");
                    $value = "'{$value}'";

                    if(($key === 0) || ($key ===1))
                    {
                        $array1[] = $value;
                    }
                    else
                    {
                        $array2[] = $value; 
                    }
                 }

                echo $req_string1 = implode(',',$array1);
                echo "<br>";
                echo $req_string2 = implode(',',$array2);     


             ?>

或者，根据语法的困难程度，可以将其用于简单的解析器。找到第一个

，

，然后找到下一个

，

，然后是一个

，

，然后是一个

，
，然后是下一个
，
，你就得到了字符串的第一部分…
，因为你说引号之间可以有逗号。。所以能比爆炸更好地帮助你

        <?php

                 $string = "'word','another word','and a sentence','and more','etc etc'";
                 $pattern = '%\',\'%';
                 $split = preg_split($pattern,$string);
                 $array1 = array();
                 $array2 = array();
                 foreach($split as $key=>$value)
                 {
                    $value  = trim($value,"'");
                    $value = "'{$value}'";

                    if(($key === 0) || ($key ===1))
                    {
                        $array1[] = $value;
                    }
                    else
                    {
                        $array2[] = $value; 
                    }
                 }

                echo $req_string1 = implode(',',$array1);
                echo "<br>";
                echo $req_string2 = implode(',',$array2);     


             ?>



显示：
