请教怎么按空行来分割txt文件,
请教怎么按空行来分割txt文件,
比如txt文件 a.txt
内容如下:
啊啊啊啊
呃呃呃
111111
222222
嘎嘎嘎嘎
嘎嘎嘎
里面有空行,怎么按空行把它切割成一段段的字符串呢
回复讨论(解决方案)
$content = file_get_contents('./a.txt');
$rows = explode("\r\n", $content);
调用函数file即可.
如果是以空行来分割就要找两个换行(\r\n)了
$str='123
defsf
abc
1213
&*(
';
print_r(explode("\n\r",$str)); //相当于print_r(explode("\r\n\r\n",$str));
或者用正则
preg_match('/[^.]+?(?=\r\n\r\n)/',$str,$mat);
print_r($mat);
正则那个用preg_match_all,少写了
$s =<<< TXT啊啊啊啊呃呃呃111111222222嘎嘎嘎嘎嘎嘎嘎TXT;$a = preg_split("/([\r\n]+)\\1/", $s);print_r($a);
Array( [0] => 啊啊啊啊呃呃呃 [1] => 111111222222 [2] => 嘎嘎嘎嘎嘎嘎嘎)
$s =<<< TXT啊啊啊啊呃呃呃111111222222嘎嘎嘎嘎嘎嘎嘎TXT;$a = preg_split("/([\r\n]+)\\1/", $s);print_r($a);
Array( [0] => 啊啊啊啊呃呃呃 [1] => 111111222222 [2] => 嘎嘎嘎嘎嘎嘎嘎)
我测试这段代码的结果是
Array ( [0] => 啊啊啊啊 呃呃呃 111111 222222 嘎嘎嘎嘎 嘎嘎嘎 )
如果文件数据比较小可以考虑先将内容一次性读取出来,然后使用explode方法进行分割。
如果文件非常大,一次性加载必然造成内存占用过大,性能低下。这种情况可以考虑open文件之后,逐行读取,对行数据进行校验从而进行分割。
$content = file_get_contents('./a.txt');
$rows = explode("\r\n", $content);
这样是按照换行分割,而不是按照空格分割,这样的结果会输出
Array ( [0] => 啊啊啊啊 [1] => 呃呃呃 [2] => [3] => 111111 [4] => 222222 [5] => [6] => 嘎嘎嘎嘎 [7] => 嘎嘎嘎 [8] => )
按照3楼的朋友说的使用$rows = explode("\r\n\r\n", $content);
输出的结果为
Array ( [0] => 啊啊啊啊 呃呃呃 111111 222222 嘎嘎嘎嘎 嘎嘎嘎 )
