(PHP ActiveX) Keeping Query Params in a Hashtable

Demonstrates how to use a Chilkat Hashtable to hold query params and re-emit as a query param string.

Note: The ToQueryString method was added in Chilkat v9.5.0.92.

<?php

// For versions of Chilkat < 10.0.0, use new COM('Chilkat_9_5_0.Chilkat.Hashtable')
$ht = new COM("Chilkat.Hashtable");

// Add name/value pairs from an existing query param string where the values are already URL encoded.
$qp = 'txt=this%20is%20a%20test&color=blue&fruits=apples%26oranges';
$success = $ht->AddQueryParams($qp);

// Add some additional name/value pairs.
$ht->AddStr('name','Jack Sparrow');
$ht->AddStr('movie','Pirates of the Carribean');

// Iterate over the hash table to show what we have..

// For versions of Chilkat < 10.0.0, use new COM('Chilkat_9_5_0.Chilkat.StringTable')
$keys = new COM("Chilkat.StringTable");
$ht->GetKeys($keys);
$numKeys = $keys->Count;

$i = 0;
while ($i < $numKeys) {
    $key = $keys->stringAt($i);
    $val = $ht->lookupStr($key);
    print $key . ' = ' . $val . "\n";
    $i = $i + 1;
}

// Output for the above loop:

// color = blue
// name = Jack Sparrow
// fruits = apples&oranges
// txt = this is a test
// movie = Pirates of the Carribean

// Get all name/value pairs as a query parm string with values URL encoded
$qp = $ht->toQueryString();
print $qp . "\n";

// Result:
// color=blue&name=Jack%20Sparrow&fruits=apples%26oranges&txt=this%20is%20a%20test&movie=Pirates%20of%20the%20Carribean
