(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 add.
-
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"; ?>
