Cast arrays to other data type in PHP
Description
The following code shows how to cast arrays to other data type.
Example
/* w ww .jav a 2 s . c o m*/
<?php
$userInfo = array(
"Name"=>"XML",
"Location"=>"Main Street, California",
"Occupation"=>"Programmer",
"PHP Version"=>5.0);
//Whether a boolean, integer or double,
//PHP converts the array to 1
$asBool = (boolean)$userInfo;
print("Boolean: $asBool<br>\n");
$asInt = (integer)$userInfo;
print("Integer: $asInt<br>\n");
$asDouble = (double)$userInfo;
print("Double: $asDouble<br>\n");
//converting to a string, PHP returns the string "Array"
$asString = (string)$userInfo;
print("String: $asString<br>\n");
//promote an array to a string
print("Promoted to string:" . $userInfo . "<br>\n");
?>
The code above generates the following result.
