将字符串拆分为文本和数字

I have some strings which can be in the following format

我有一些字符串,可以采用以下格式

sometext moretext 01 text
text sometext moretext 002
text text 1 (somemoretext)
etc

I want to split these strings into following: text before the number and the number

我想将这些字符串拆分为以下内容:数字和数字之前的文本

For example: text text 1 (somemoretext)
When split will output:
text = text text
number = 1

Anything after the number can be discarded

例如:文本文本1(somemoretext)当分割将输出:text = text text number = 1数字后面的任何内容都可以丢弃

Have read up about using regular expressions and maybe using preg_match or preg_split but am lost when it comes to the regular expression part

已经阅读了有关使用正则表达式的信息,并且可能使用preg_match或preg_split,但在正则表达式部分时却丢失了

2 个解决方案

#1

preg_match('/[^\d]+/', $string, $textMatch);
preg_match('/\d+/', $string, $numMatch);

$text = $textMatch[0];
$num = $numMatch[0];

Alternatively, you can use preg_match_all with capture groups to do it all in one shot:

或者,您可以将preg_match_all与捕获组一起使用,一次完成所有操作:

preg_match_all('/^([^\d]+)(\d+)/', $string, $match);

$text = $match[1][0];
$num = $match[2][0];

#2

Use preg_match_all() + if you wish to match every line use m modifier:

如果你想匹配每一行使用m修饰符,请使用preg_match_all()+:

$string = 'sometext moretext 01 text
text sometext moretext 002
text text 1 (somemoretext)
etc';
preg_match_all('~^(.*?)(\d+)~m', $string, $matches);

All your results are in $matches array, which looks like this:

你的所有结果都在$ matches数组中,如下所示:

Array
(
    [0] => Array
        (
            [0] => sometext moretext 01
            [1] => text sometext moretext 002
            [2] => text text 1
        )
    [1] => Array
        (
            [0] => sometext moretext 
            [1] => text sometext moretext 
            [2] => text text 
        )
    [2] => Array
        (
            [0] => 01
            [1] => 002
            [2] => 1
        )
)

Output example:

foreach ($matches[1] as $k => $text) {
    $int = $matches[2][$k];
    echo "$text => $int\n";
}

#1

preg_match('/[^\d]+/', $string, $textMatch);
preg_match('/\d+/', $string, $numMatch);

$text = $textMatch[0];
$num = $numMatch[0];
