我想在每3 .
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()
功能,然后将它们重新添加。像这样:
$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] . ".";
}
然后,您必须弄清楚您是否希望保留最终.
。您可以使用substr()
功能删除它:link。

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));
输出
array (size=3)
0 => string 'ABC. ABC. ABC' (length=13)
1 => string 'ABC. ABC. ABC' (length=13)
2 => string 'ABC. ABC. ' (length=10)
答案 2 :(得分:2)
您可能想尝试一下:
$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>";
如果它真的与句子有关,它们通常以句号(“。”)结束,后跟空格(“”)。要在结果中避免这些空格,可以使用以下正则表达式:
$result = preg_split("%((?:[^\.]*?\.\s?){3})%s", $test, -1,
PREG_SPLIT_NO_EMPTY + PREG_SPLIT_DELIM_CAPTURE);
