PHP - 後具體occurence分割字符串後特殊字符

Question

我想每3 .

例如字符串後，打破了一句：

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

預期的結果：

[0] = ABC. ABC. ABC 

[1] = ABC. ABC. ABC 

[2] = ABC. ABC. 

Answer 1

你會想要使用explode()函數，然後將它們添加回來。事情是這樣的：

$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] . "."; 
} 

然後，你必須搞清楚，如果你想在最終.留與否。您可以使用substr()功能刪除它：link。

試試這個

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)); 

輸出將被

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

Answer 3

你可能想試試這個：

$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>"; 

如果它的的確確是句子，他們通常用句號結尾（「。」），後跟一個空格（「」）。爲避免你的結果，這些空間您可以使用下面的正則表達式：

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