(PHP 4, PHP 5)
var_dump — Dumps information about a variable
This function displays structured information about one or more expressions that includes its type and value. Arrays and objects are explored recursively with values indented to show structure.
In PHP 5 all public, private and protected properties of objects will be returned in the output.
Precis som med allting som skickar sin utdata direkt till webbläsaren kan du använda output-control-funktioner för att fånga datan från denna funktion, och spara den i en sträng (till exempel).
The variable you want to export.
No value is returned.
Example#1 var_dump() example
<?php
$a = array(1, 2, array("a", "b", "c"));
var_dump($a);
?>
The above example will output:
array(3) { [0]=> int(1) [1]=> int(2) [2]=> array(3) { [0]=> string(1) "a" [1]=> string(1) "b" [2]=> string(1) "c" } }
<?php
$b = 3.1;
$c = true;
var_dump($b, $c);
?>
The above example will output:
float(3.1) bool(true)
