由字符串的最後一次出現在字符串中返回第一個和最後一個部分導致字符串爆炸

Question

更新：$字符串可以有一個或多個「;」。我必須照顧最後一個。

$string = "Hello world; This is a nice day; after"; 

$out[] = trim(substr(strrchr ($string, ";"), 1)); 
$out[] = trim(substr(strrchr ($string, ";"), 0)); 

var_dump($out); 

結果： 陣列（2）{ [0] => 串（3） 「後」 [1] => 串（5） 「;之後」 }

但我需要的是：

陣列（2）{ [0] => 串（3） 「後」 [1] => 串（5）的「Hello world;這是一個美好的一天「 }

我應該怎麼做？

Answer 1

 
$dlm = "; "; 
$string = "Hello world; This is a nice day; after"; 

$split = explode($dlm,$string); 
$last = array_pop($split); 
$out = array($last,implode($dlm,$split)); 

Answer 2

嘗試

string = "Hello world; This is a nice day; after"; 
$out[] = trim(substr(strrchr($string, ";"), 1)); 
$out[] = trim(substr($string, 0, strrpos($string, ";")+1)); 

觀看演示here

Answer 3

你可以嘗試使用：

$string = "Hello world; This is a nice day; after"; 
$parts = explode(';', $string); 
$output = array(trim(array_pop($parts)), implode(';', $parts)); 

var_dump($output); 

輸出：

array (size=2) 
    0 => string 'after' (length=5) 
    1 => string 'Hello world; This is a nice day' (length=31) 

Answer 4

$string = "Hello world; This is a nice day; after"; 
$offset = strrpos($string,';'); 

$out[] = substr($string, $offset+1); 
$out[] = trim(substr($string, 0, $offset)); 
print_r($out); 

Answer 5

$string = "Hello world; This is a nice day; after"; 
/// Explode it 
$exploded_string = explode(";", $string); 
/// Get last element 
$result['last_one'] = end($exploded_string); 
/// Remove last element 
array_pop($exploded_string); 
/// Implode other ones 
$result['previous_ones'] = implode(";", $exploded_string); 

print_r($result); 

結果將是：

Array ([last_one] => after [previous_ones] => Hello world; This is a nice day)
