我想每3 .PHP - 后具体occurence分割字符串后特殊字符

例如字符串后,打破了一句:

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

预期的结果:

[0] = ABC. ABC. ABC 

[1] = ABC. ABC. ABC 

[2] = ABC. ABC. 
+0

,是它(离开周期之后的情况,因为你的文字说的)或“第三时期”,“第3期后”(删除期间,如你预期的结果所示)? – Amadan

+0

你会想要使用explode()函数,然后将它们添加回来。事情是这样的:

$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] . "."; 
} 

然后,你必须搞清楚,如果你想在最终.留与否。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)); 

输出将被

array (size=3) 
    0 => string 'ABC. ABC. ABC' (length=13) 
    1 => string 'ABC. ABC. ABC' (length=13) 
    2 => string 'ABC. ABC. ' (length=10)

你可能想试试这个:

$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>"; 

如果它的的确确是句子,他们通常用句号结尾(“。”),后跟一个空格(“”)。为避免你的结果,这些空间您可以使用下面的正则表达式:

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