PHP PHPUnit assertStringMatchesFormat()用法及代码示例

assertStringMatchesFormat()函数是PHPUnit中的内置函数，用于断言给定的字符串是否与格式匹配。如果给定的字符串与格式类型匹配，则此断言将返回true，否则返回false。如果为真，则通过断言的测试用例，否则测试用例失败。

用法:

assertStringMatchesFormat(string $format, string $string[, string $message = ''])

参数：此函数接受上述和以下所述的三个参数：

$format:此参数表示数据的预建立布局。
$string:此参数可以是表示字符串的任何类型。
$message:此参数采用字符串值。当测试用例失败时，此字符串消息将显示为错误消息。

以下示例说明了PHPUnit中的assertStringMatchesFormat()函数：

{  
    public function testNegativeTestcaseForassertStringMatchesFormat() 
    {  
        $format =  "%d";  
        $String  =  "hh"; 
        
        // Assert function to test whether given  
        // string is matched with type of format or not 
        $this->assertStringMatchesFormat(
