QuickHashIntHash::update — This method updates an entry in the hash with a new value

说明

public QuickHashIntHash::update ( int $key , int $value ) : bool

This method updates an entry with a new value, and returns whether the entry was 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.
value: The new value to update the entry with.

返回值

TRUE when the entry was found and updated, and FALSE if the entry was not part of the hash already.

范例

Example #1 QuickHashIntHash::update() example


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

var_dump( $hash->add( 141421, 173205 ) );
var_dump( $hash->update( 141421, 223606 ) );
var_dump( $hash->get( 141421 ) );
?>

以上例程的输出类似于：

bool(true)
bool(true)
int(223606)
