使用php从字符串中提取子字符串

Question

我需要使用php从另一个字符串中提取子字符串。

$string = 'This is my string that conteined a Code:XYZ123';
$code = substr($text, -1, strpos($string,'Code:'));
echo $code ; // return 3

我需要整个代码，例如XYZ123

Answer 1

您需要“代码：”的起始位置加上“代码：”的长度

$string = 'This is my string that conteined a Code:XYZ123'; 
$code = substr($string, strpos($string,'Code:') + 5); 
echo $code; //XYZ123

Answer 2

另一个选择是爆炸字符串my Code:并回显数组的第二部分

$code = explode( 'Code:', $string );
echo $code[ 1 ]

Answer 3

试试这段代码：

$string = 'This is my string that conteined a Code:XYZ123';
$code = substr($string ,strpos($string,'Code:'));
echo $code;

确保这对您有所帮助。
