QuickHashStringIntHash::set
(No version information available, might only be in Git)
QuickHashStringIntHash::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
$key
, int $value
)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 QuickHashStringIntHash::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 QuickHashStringIntHash::set() example
<?php
$hash = new QuickHashStringIntHash( 1024 );
echo "Set->Add\n";
var_dump( $hash->get( "fourty six thousand six hundred ninety two" ) );
var_dump( $hash->set( "fourty six thousand six hundred ninety two", 16091 ) );
var_dump( $hash->get( "fourty six thousand six hundred ninety two" ) );
echo "Set->Update\n";
var_dump( $hash->set( "fourty six thousand six hundred ninety two", 29906 ) );
var_dump( $hash->get( "fourty six thousand six hundred ninety two" ) );
