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

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.

示例

示例 #1 QuickHashStringIntHash::set() example

<?php
$hash = new QuickHashStringIntHash( 1024 );

echo "Set->Add\n";
var_dump( $hash->get( "forty six thousand six hundred ninety two" ) );
var_dump( $hash->set( "forty six thousand six hundred ninety two", 16091 ) );
var_dump( $hash->get( "forty six thousand six hundred ninety two" ) );

echo "Set->Update\n";
var_dump( $hash->set( "forty six thousand six hundred ninety two", 29906 ) );
var_dump( $hash->get( "forty six thousand six hundred ninety two" ) );
?>

以上示例的输出类似于：

Set->Add
bool(false)
int(2)
int(16091)
Set->Update
int(1)
int(29906)
