# QuickHashIntStringHash::set

(PECL quickhash >= Unknown)

QuickHashIntStringHash::set — This method updates an entry in the hash with a new value, or adds a new one if the entry doesn't exist

### Description

public QuickHashIntStringHash::set(int `$key`, string `$value`): int

This method tries to update an entry with a new value. In case the entry did not yet exist, it will instead add a new entry. It returns whether the entry was added or update. If there are duplicate keys, only the first found element will get an updated value. Use QuickHashIntStringHash::CHECK_FOR_DUPES during hash creation to prevent duplicate keys from being part of the hash.

### Parameters

`key`
  The key of the entry to add or update.
`value`
  The value of the entry to add. If a non-string is passed, it will be converted to a string automatically if possible.

### Return Values

2 if the entry was found and updated, 1 if the entry was newly added or 0 if there was an error.

### Examples

Example #1 QuickHashIntStringHash::set() example

`<?php
$hash = new QuickHashIntStringHash( 1024 );
echo "Set->Add\n";
var_dump( $hash->get( 46692 ) );
var_dump( $hash->set( 46692, "sixteen thousand ninety one" ) );
var_dump( $hash->get( 46692 ) );
echo "Set->Update\n";
var_dump( $hash->set( 46692, "twenty nine thousand nine hundred six" ) );
var_dump( $hash->get( 46692 ) );
?>`

The above example will output something similar to:

    Set->Add
    bool(false)
    int(2)
    string(27) "sixteen thousand ninety one"
    Set->Update
    int(1)
    string(37) "twenty nine thousand nine hundred six"
