How to pass array as a parameter?

[victoria]

In the script I have an array and I need to pass it to another script as a parameter.

How to pass arrays?

Have you considered using sessions to maintain the variable between pages?

Use the serialize/unserialize functions, and pass the values using POST. Good work!!!

[sepodati]

Use addslashes() around the value, since serialize makes use of single quotes...

Is your other script going to know how to decode the variable? Is it PHP also?

A serialized array is passed directly by a form containing a single hidden input field. The target script decodes a variable and knows to handle it. There is no necessity to use addslashes()/stripslashes() because magic_quotes_gpc in "php.ini" is set to Off.

<?php

$var[] = "one";
$var[] = "two";
$var[] = 1;
$var[] = 2;
$var[] = "That's good";

$ser = serialize($var);
echo $ser;

?>

produces:

a:5:{i:0;s:3:"one";i:1;s:3:"two";i:2;i:1;i:3;i:2;i:4;s:11:"That's good";}

So, if you have

1. <input typ=hidden name=ser value='$ser'>
   or
2. <input type=hidden name=ser value="$ser">
   or
3. <input type=hidden name=ser value=$ser>

you will end up with:

1. a:5:{i:0;s:3:"one";i:1;s:3:"two";i:2;i:1;i:3;i:2;i:4;s:11:"That'

2. a:5:{i:0;s:3:"

3. a:5:{i:0;s:3:"one";i:1;s:3:"two";i:2;i:1;i:3;i:2;i:4;s:11:"That's

So...you won't get the correct values unless you use addslashes().

Note: if you're array is all integers, then you don't need to worry about it.

John,

Using your example with addslashes(), and look at the result:

<?php
$var[] = "one";
$var[] = "two";
$var[] = 1;
$var[] = 2;
$var[] = "That's good";

    $ser = addslashes( serialize( $var ) ); 
    echo $ser; 

?>

That will produce the output:

a:5:{i:0;s:3:\"one\";i:1;s:3:\"two\";i:2;i:1;i:3;i:2;i:4;s:11:\"That\'s good\";}

If you put this in a hidden form:

1. <input type=hidden name=ser value='<?php echo $ser; ?>'>
2. <input type=hidden name=ser value="<?php echo $ser; ?>">
3. <input type=hidden name=ser value=<?php echo $ser; ?>>

You will obtain the result:

1. a:5:{i:0;s:3:\"one\";i:1;s:3:\"two\";i:2;i:1;i:3;i:2;i:4;s:11:\"That\

2. a:5:{i:0;s:3:\

3. a:5:{i:0;s:3:\"one\";i:1;s:3:\"two\";i:2;i:1;i:3;i:2;i:4;s:11:\"That\'s

So, the use of addslashes() don't work! I prefer to use the "1." method, but replace the plicks (') for other non-printable character, always setting the magic_quotes to Off.
