(PECL quickhash >= Unknown)
QuickHashIntHash::delete — This method deletes am entry from the hash
说明
public
QuickHashIntHash::delete (
int
$key
) :
bool
This method deletes an entry from the hash, and returns whether the entry was deleted or not. Associated memory structures will not be freed immediately, but rather when the hash itself is freed.
Elements can not be deleted when the hash is used in an iterator. The method will not throw an exception, but simply return FALSE
like would happen with any other deletion failure.
参数
-
key
-
The key of the entry to delete.
返回值
TRUE
when the entry was deleted, and FALSE
if the entry was not deleted.
范例
Example #1 QuickHashIntHash::delete() example
<?php
$hash = new QuickHashIntHash( 1024 );
var_dump( $hash->exists( 4 ) );
var_dump( $hash->add( 4, 5 ) );
var_dump( $hash->delete( 4 ) );
var_dump( $hash->exists( 4 ) );
var_dump( $hash->delete( 4 ) );
?>
以上例程的输出类似于:
bool(false) bool(true) bool(true) bool(false) bool(false)
