(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
说明
public QuickHashStringIntHash::set
( string $key
, int $value
) : int
This method tries to update an entry with a new value. In case the entry did not yet exist, it will instead add a new entry. It returns whether the entry was added or update. If there are duplicate keys, only the first found element will get an updated value. Use QuickHashStringIntHash::CHECK_FOR_DUPES during hash creation to prevent duplicate keys from being part of the hash.
参数
key- The key of the entry to add or update.
value- The value of the entry to add. If a non-string is passed, it will be converted to a string automatically if possible.
返回值
2 if the entry was found and updated, 1 if the entry was newly added or 0 if there was an error.
范例
Example #1 QuickHashStringIntHash::set() example
<?php$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" ) );?>
以上例程的输出类似于：
Set->Add bool(false) int(2) int(16091) Set->Update int(1) int(29906)
