Question

我有一個包含這樣的文本字符串：每號/詩

$string = "1 In the beginning, God created the heavens and the earth. 2 The earth was without form and void, and darkness was over the face of the deep. And the Spirit of God was hovering over the face of the waters. 
    3 And God said, 「Let there be light,」 and there was light. 4 And God saw that the light was good. And God separated the light from the darkness. 5 God called the light Day, and the darkness he called Night. And there was evening and there was morning, the first day. 
    6 And God said, 「Let there be an expanse1 in the midst of the waters, and let it separate the waters from the waters.」 7 And God made2 the expanse and separated the waters that were under the expanse from the waters that were above the expanse. And it was so. 8 And God called the expanse Heaven.3 And there was evening and there was morning, the second day. 
    9 And God said, 「Let the waters under the heavens be gathered together into one place, and let the dry land appear.」 And it was so. 10 God called the dry land Earth,4 and the waters that were gathered together he called Seas. And God saw that it was good."; 

我要的是\ r \ n（新行）。

Answer 1

$regex = '/\d*+\s+(?=[0-9])/'; 
$string = preg_replace($regex, '<br>', $string); //for HTML output 
$string = preg_replace($regex, '\r\n', $string); //for txt file 

這將保留各自領先行的數量。輸出：

1 In the beginning, God created the heavens and the earth. 
2 The earth was without form and void, and darkness was over the face of the deep. And the Spirit of God was hovering over the face of the waters. 
3 And God said, 「Let there be light,」 and there was light. 
4 And God saw that the light was good. And God separated the light from the darkness. 
5 God called the light Day, and the darkness he called Night. And there was evening and there was morning, the first day. 
6 And God said, 「Let there be an expanse1 in the midst of the waters, and let it separate the waters from the waters.」 
7 And God made2 the expanse and separated the waters that were under the expanse from the waters that were above the expanse. And it was so. 
8 And God called the expanse Heaven.3 And there was evening and there was morning, the second day. 
9 And God said, 「Let the waters under the heavens be gathered together into one place, and let the dry land appear.」 And it was so. 
10 God called the dry land Earth,4 and the waters that were gathered together he called Seas. And God saw that it was good. 

Answer 2

使用preg_replace：

$replaced = preg_replace('/\d+/', "\r\n", $string); 

見https://3v4l.org/D5eNc。

注意，雖然，你可能要前後更換可選的空白，也因此這可能是一個更好的選擇：

$replaced = preg_replace('/\s*\d+\s*/', "\r\n", $string); 

見https://3v4l.org/5Xv10。

Answer 3

您可以使用preg_replace（）和'br'。下面的代碼可以幫助你。

$string = "1 In the beginning, God created the heavens and the earth. 2 The earth was without form and void, and darkness was over the face of the deep. And the Spirit of God was hovering over the face of the waters. 
3 And God said, 「Let there be light,」 and there was light. 4 And God saw that the light was good. And God separated the light from the darkness. 5 God called the light Day, and the darkness he called Night. And there was evening and there was morning, the first day. 
6 And God said, 「Let there be an expanse1 in the midst of the waters, and let it separate the waters from the waters.」 7 And God made2 the expanse and separated the waters that were under the expanse from the waters that were above the expanse. And it was so. 8 And God called the expanse Heaven.3 And there was evening and there was morning, the second day. 
9 And God said, 「Let the waters under the heavens be gathered together into one place, and let the dry land appear.」 And it was so. 10 God called the dry land Earth,4 and the waters that were gathered together he called Seas. And God saw that it was good."; 
echo $string; 

$split =preg_replace('/\d+\s+/','<br>',$string); 
echo $split; 

Answer 4

從這裏你可以得到你的不同字符串的數組，現在遍歷它並以新行打印。

$pattern = "/(\d)/"; 

$array = array_filter(preg_split($pattern, $string)); 
print_r($array); 

此外，您可以通過使用preg_replace獲得直接輸出。但那裏的領先空間。

echo preg_replace($pattern,'<br/>',$string);
