php用到的几个工具方法

2018年8月13日

验证手机号，这个地方是粗校验，手机号，现在几乎那个号段都有啦，看代码

/**
 * 验证手机号是否正确
 * return bool
 */
function vali_phone($phone) {
	$p = '/^1[0-9]{10}$/';
	if (! preg_match ( $p, $phone )) {
		return false;
	}
	return true;
}

/**

* 验证手机号是否正确

* return bool

function vali_phone($phone) {

$p = '/^1[0-9]{10}$/';

if (! preg_match ( $p, $phone )) {

return false;

}

return true;

}

隐藏手机号，一般如果前端要显示手机号，为了用户隐私一般都会隐藏几位！

/**
 * 隐藏手机号
 * return string
 */
function hidePhone($phone) {
    if ($phone=='') {
        return "";
    }
    $phone = substr($phone, 0,3)."*****".substr($phone, 8);
    return $phone;
}

/**

* 隐藏手机号

* return string

function hidePhone($phone) {

if ($phone=='') {

return "";

}

$phone = substr($phone, 0,3)."*****".substr($phone, 8);

return $phone;

}

php中有时候需要跳转到指定url,封装了方法，指定了几种跳转方式！

/**
 * url跳转
 *
 * @param unknown $url        	
 * @param unknown $error        	
 * @param string $type        	
 */
function redirectReturn($url, $error = '', $type = false) {
	switch ($type) {
		case 'script_parent' :
			echo "
            <script>
            parent.location.href = '{$url}';
            </script>
            ";
			exit ();
		case 'script_top' :
			echo "
            <script>
            top.location.href = '{$url}';
            </script>
            ";
			exit ();
		default :
			if (isset ( $_REQUEST ['callback'] )) {
				// jsonp
				ajax( 1,array (
						'url' => $url 
				), $error );
			} else {
				header ( "Location: {$url}" );
				exit ();
			}
	}
}

/**

* url跳转

* @param unknown $url

* @param unknown $error

* @param string $type

function redirectReturn($url, $error = '', $type = false) {

switch ($type) {

case 'script_parent' :

echo "

parent.location.href = '{$url}';

</script>

exit ();

case 'script_top' :

echo "

top.location.href = '{$url}';

</script>

exit ();

default :

if (isset ( $_REQUEST ['callback'] )) {

// jsonp

ajax( 1,array (

'url' => $url

), $error );

} else {

header ( "Location: {$url}" );

exit ();

}

跳转的时候，有时候需要增加参数

function url_add_param($url, $name, $value) {
	$check = strpos ( $url, '?' );
	if ($check) {
		if (substr ( $url, $check + 1 ) == '') {
			return "{$url}{$name}={$value}";
		} else {
			return "{$url}&{$name}={$value}";
		}
	} else {
		return "{$url}?{$name}={$value}";
	}
}
