php-在特定出现后按特殊字符拆分字符串

我想在每三次之后破译一个句子

示例字符串：

$var = "ABC.ABC.ABC.ABC.ABC.ABC.ABC.ABC.";

预期结果：

[0] = ABC. ABC. ABC

[1] = ABC. ABC. ABC

[2] = ABC. ABC.

您需要使用

explode（）

函数，然后将它们重新添加到一起。大概是这样的：

$line = "ABC.ABC.ABC.ABC.ABC.ABC.ABC.ABC.";
$tempSplit = explode(".", $line);

$result;
for ($x = 0; $x < count($tempSplit); $x++)
{
    $result[intval($x / 3)] .= $tempSplit[$x] . ".";
}

$line=“ABC.ABC.ABC.ABC.ABC.ABC.ABC.ABC.”；
$tempSplit=分解（“.”，$line）；
$result；
对于（$x=0；$x

然后你必须弄清楚你是否希望最后的

留下来。您可以使用

substr（）

函数将其删除。

试试这个

var = "ABC.ABC.ABC.ABC.ABC.ABC.ABC.ABC.";
$array=explode(".", $var);
$str="";
$count=0;
$arr="";
for($i=0;$i<sizeof($array);$i++){
    $str[]=$array[$i];

    $count++;
    if($count>2){
        $arr[$i]=implode(". ",$str);
        $str="";
        $count=0;

    }

}
var_dump(array_values($arr));

您可能希望尝试以下方法：

$test = "ABC.ABC.ABC.ABC.ABC.ABC.ABC.ABC.\n"
      . "The quick brown fox jumps over the lazy dog.\n"
      . "Lorem ipsizzle dolizzle you son of a bizzle amizzle, \n"
      . "its fo rizzle adipiscing elit. The bizzle tellivizzle \n"
      . "velizzle, gizzle volutpizzle, suscipizzle bow wow wow, \n"
      . "owned vizzle, owned. Pellentesque bow wow wow tortor. \n"
      . "Sizzle erizzle. Shizznit izzle dolor dapibus get down \n"
      . "get down tempizzle yo. Maurizzle go to hizzle bizzle \n"
      . "izzle. Da bomb izzle dawg. Pellentesque eleifend \n"
      . "rhoncus dope. In sure break yo neck, yall shiz \n"
      . "dictumst. Shiznit dapibus. Curabitizzle boom \n"
      . "shackalack fo shizzle mah nizzle fo rizzle, mah \n"
      . "home g-dizzle, pretizzle rizzle, mattizzle crackalackin, \n"
      . "eleifend funky fresh, nunc. Shit suscipizzle. Integizzle \n"
      . "sempizzle velit sed daahng dawg.";

$result = preg_split("%((?:[^\.]*?\.){3})%s", $test, -1,
          PREG_SPLIT_NO_EMPTY + PREG_SPLIT_DELIM_CAPTURE);

echo "<pre>"; print_r ($result); echo "</pre>";

是“在第三个周期之后”（如您的文本所示，将该周期留到后面）还是“在第三个周期上”（如您预期的结果所示，删除该周期）？我们在此不提供从头开始的代码。请看一下和

$test = "ABC.ABC.ABC.ABC.ABC.ABC.ABC.ABC.\n"
      . "The quick brown fox jumps over the lazy dog.\n"
      . "Lorem ipsizzle dolizzle you son of a bizzle amizzle, \n"
      . "its fo rizzle adipiscing elit. The bizzle tellivizzle \n"
      . "velizzle, gizzle volutpizzle, suscipizzle bow wow wow, \n"
      . "owned vizzle, owned. Pellentesque bow wow wow tortor. \n"
      . "Sizzle erizzle. Shizznit izzle dolor dapibus get down \n"
      . "get down tempizzle yo. Maurizzle go to hizzle bizzle \n"
      . "izzle. Da bomb izzle dawg. Pellentesque eleifend \n"

      . "sempizzle velit sed daahng dawg.";

$result = preg_split("%((?:[^\.]*?\.){3})%s", $test, -1,
          PREG_SPLIT_NO_EMPTY + PREG_SPLIT_DELIM_CAPTURE);

echo "<pre>"; print_r ($result); echo "</pre>";

$result = preg_split("%((?:[^\.]*?\.\s?){3})%s", $test, -1,
          PREG_SPLIT_NO_EMPTY + PREG_SPLIT_DELIM_CAPTURE);
