wddx_add_vars
Add variables to a WDDX packet with the specified ID
Warning
该函数已在 PHP 7.4.0 中 移除。
说明
bool <span
class="methodname">wddx_add_vars ( <span
class="methodparam">resource
$packet_id , <span
class="type">mixed $var_name , <span
class="methodparam">mixed $var_names
)
Serializes the passed variables and add the result to the given packet.
参数
This function takes a variable number of parameters.
packet_id
A WDDX packet, returned by <span
class="function">wddx_packet_start.
var_name
Can be either a string naming a variable or an array containing strings
naming the variables or another array, etc.
var_names
返回值
成功时返回 true， 或者在失败时返回 false。
wddx_deserialize
Unserializes a WDDX packet
Warning
该函数已在 PHP 7.4.0 中 移除。
说明
mixed <span
class="methodname">wddx_deserialize ( <span
class="methodparam">string $packet )
Unserializes a WDDX packet.
Warning
Do not pass untrusted user input to <span class="function">wddx_deserialize. Unserialization can result in code being loaded and executed due to object instantiation and autoloading, and a malicious user may be able to exploit this. Use a safe, standard data interchange format such as JSON (via <span class="function">json_decode and <span class="function">json_encode) if you need to pass serialized data to the user.
参数
packet
A WDDX packet, as a string or stream.
返回值
Returns the deserialized value which can be a string, a number or an array. Note that structures are deserialized into associative arrays.
wddx_packet_end
Ends a WDDX packet with the specified ID
Warning
该函数已在 PHP 7.4.0 中 移除。
说明
string <span
class="methodname">wddx_packet_end ( <span
class="methodparam">resource
$packet_id )
Ends and returns the given WDDX packet.
参数
packet_id
A WDDX packet, returned by <span
class="function">wddx_packet_start.
返回值
Returns the string containing the WDDX packet.
wddx_packet_start
Starts a new WDDX packet with structure inside it
Warning
该函数已在 PHP 7.4.0 中 移除。
说明
resource <span
class="methodname">wddx_packet_start ([ <span
class="methodparam">string $comment
] )
Start a new WDDX packet for incremental addition of variables. It automatically creates a structure definition inside the packet to contain the variables.
参数
comment
An optional comment string.
返回值
Returns a packet ID for use in later functions, or false on error.
wddx_serialize_value
Serialize a single value into a WDDX packet
Warning
该函数已在 PHP 7.4.0 中 移除。
说明
string <span
class="methodname">wddx_serialize_value ( <span
class="methodparam">mixed $var [,
string
$comment ] )
Creates a WDDX packet from a single given value.
参数
var
The value to be serialized
comment
An optional comment string that appears in the packet header.
返回值
Returns the WDDX packet, or false on error.
wddx_serialize_vars
Serialize variables into a WDDX packet
Warning
该函数已在 PHP 7.4.0 中 移除。
说明
string <span
class="methodname">wddx_serialize_vars ( <span
class="methodparam">mixed $var_name ,
mixed
$var_names )
Creates a WDDX packet with a structure that contains the serialized representation of the passed variables.
参数
This function takes a variable number of parameters.
var_name
Can be either a string naming a variable or an array containing strings
naming the variables or another array, etc.
var_names
返回值
Returns the WDDX packet, or false on error.
范例
示例 #1 wddx_serialize_vars example
<?php
$a = 1;
$b = 5.5;
$c = array("blue", "orange", "violet");
$d = "colors";
$clvars = array("c", "d");
echo wddx_serialize_vars("a", "b", $clvars);
?>以上例程会输出：
<wddxPacket version='1.0'><header/><data><struct><var name='a'><number>1</number></var>
<var name='b'><number>5.5</number></var><var name='c'><array length='3'>
<string>blue</string><string>orange</string><string>violet</string></array></var>
<var name='d'><string>colors</string></var></struct></data></wddxPacket>目录
