QuickHashIntStringHash::update

(PECL quickhash >= Unknown)

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

Description

public QuickHashIntStringHash::update(int $key, string $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 QuickHashIntStringHash::CHECK_FOR_DUPES during hash creation to prevent duplicate keys from being part of the hash.

Parameters

key: The key of the entry to update.
value: The new value for the entry. If a non-string is passed, it will be converted to a string automatically if possible.

Return Values

true when the entry was found and updated, and false if the entry was not part of the hash already.

Examples

Example #1 QuickHashIntStringHash::update() example


<?php
$hash->add( 161803398, "--" );
$hash->add( 314159265, "a lot" );

echo $hash->get( 161803398 ), "\n";
echo $hash->get( 314159265 ), "\n";

var_dump( $hash->update( 314159265, "a lot plus one" ) );
var_dump( $hash->update( 314159999, "a lot plus one" ) );

echo $hash->get( 161803398 ), "\n";
echo $hash->get( 314159265 ), "\n";
?>

The above example will output something similar to:

--
a lot
bool(true)
bool(false)
--
a lot plus one
