$string = “Hello, World!”; $substring = “o”; $count = substr_count($string, $substring); if ($count > 0) { echo “字符串包含子字符串”; } else { echo “字符串不包含子字符串”; } “` 5. str_contains()函数(PHP 8.0后新增):该函数用于判断一个字符串是否包含另一个子字符串。
if (strpos($string, $substring) !== false) { echo “The string contains the substring.”; } else { echo “The string does not contain the substring.”; } “` 2. 操作流程如下: – 首先,定义一个包含指定字段的字符串,如$string = “This is a string contains substring”; – 然后,定义...
