本文章介绍了三个自定义函数，一个日期验证，一个时间验证，一个验证是否为时间和日期的，有需要的同学可以参考五。

<script>ec(2);</script>

日期验证 格式 2011-12-12

 代码如下 复制代码
function is_date( $str )
{
        $YEAR = "";
        $MONTH = "";
        $DAY = "";
        $len = strlen( $str );
        $offset = 0;
        $i = strpos( $str, "-", $offset );
        $YEAR = substr( $str, $offset, $i - $offset );
        $offset = $i + 1;
        if ( $len         {
                return FALSE;
        }
        if ( $i )
        {
                $i = strpos( $str, "-", $offset );
                $MONTH = substr( $str, $offset, $i - $offset );
                $offset = $i + 1;
                if ( $len                 {
                        return FALSE;
                }
                if ( $i )
                {
                        $DAY = substr( $str, $offset, $len - $offset );
                }
        }
        if ( $YEAR == "" || $MONTH == "" || $DAY == "" )
        {
                return FALSE;
        }
        if ( !checkdate( intval( $MONTH ), intval( $DAY ), intval( $YEAR ) ) )
        {
                return FALSE;
        }
        return TRUE;
}

时间验证昭 11:12:32

 代码如下 复制代码
function is_time( $str )
{
        $TEMP = "";
        $HOUR = "";
        $MIN = "";
        $SEC = "";
        $TEMP = strtok( $str, ":" );
        $HOUR = $TEMP;
        if ( $HOUR == "" || 24         {
                return FALSE;
        }
        $TEMP = strtok( ":" );
        $MIN = $TEMP;
        if ( $MIN == "" || 60         {
                return FALSE;
        }
        $TEMP = strtok( ":" );
        $SEC = $TEMP;
        if ( $SEC == "" || 60         {
                return FALSE;
        }
        return TRUE;
}

时间日期验证：2011-12-12 12：12：12

 代码如下 复制代码

function is_date_time( $DATE_TIME_STR )
{
        if ( $DATE_TIME_STR == NULL || strlen( $DATE_TIME_STR ) == 0 )
        {
                return FALSE;
        }
        $DATE_TIME_ARRY = explode( " ", $DATE_TIME_STR );
        if ( is_date( $DATE_TIME_ARRY[0] ) && is_time( $DATE_TIME_ARRY[1] ) )
        {
                return TRUE;
        }
        return FALSE;
}
