从包含PHP括号的字符串中提取文本

Question

I have a string with State name and code like this

KT16(Ottershaw)

Now i need to extract text from () . I need to extract Ottershaw. How can i do this with php.

Answer 1

should be :

preg_match('/\(([^\)]*)\)/', 'KT16(Ottershaw)', $matches);
echo $matches[1];

Answer 2

Just get the substring between the first opening bracket and the last closing bracket:

$string = "KT16(Ottershaw)";
$strResult = substr($string, stripos($string, "(") +1,strrpos($string, ")") - stripos($string, "(")-1);  

Answer 3

以下RegEx应该有效：

/\[(.*?)\]/ 

Answer 4

This is a sample code to extract all the text between '[' and ']' and store it 2 separate arrays(ie text inside parentheses in one array and text outside parentheses in another array)

function extract_text($string)
   {
    $text_outside=array();
    $text_inside=array();
    $t="";
    for($i=0;$i<strlen($string);$i++)
    {
        if($string[$i]=='[')
        {
            $text_outside[]=$t;
            $t="";
            $t1="";
            $i++;
            while($string[$i]!=']')
            {
                $t1.=$string[$i];
                $i++;
            }
            $text_inside[] = $t1;

        }
        else {
            if($string[$i]!=']')
            $t.=$string[$i];
            else {
                continue;
            }

        }
    }
    if($t!="")
    $text_outside[]=$t;

    var_dump($text_outside);
    echo "\n\n";
    var_dump($text_inside);
  }

Output: extract_text("hello how are you?"); will produce:

array(1) {
  [0]=>
  string(18) "hello how are you?"
}

array(0) {
}

extract_text("hello [http://www.google.com/test.mp3] how are you?"); will produce

array(2) {
  [0]=>
  string(6) "hello "
  [1]=>
  string(13) " how are you?"
}


array(1) {
  [0]=>
  string(30) "http://www.google.com/test.mp3"
}
