QuickHashIntHash::set

(PECL quickhash >= Unknown)

QuickHashIntHash::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 QuickHashIntHash::set ( int $key , int $value ) : bool

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 QuickHashIntHash::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 new value to set the entry with.

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 QuickHashIntHash::set() example


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

echo "Set->Add\n";
var_dump( $hash->get( 46692 ) );
var_dump( $hash->set( 46692, 16091 ) );
var_dump( $hash->get( 46692 ) );

echo "Set->Update\n";
var_dump( $hash->set( 46692, 29906 ) );
var_dump( $hash->get( 46692 ) );
?>

以上例程的输出类似于：

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