QuickHashIntStringHash::delete — This method deletes am entry from the hash
$key
)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.
key
The key of the entry to delete.
TRUE
when the entry was deleted, and FALSE
if the entry was not deleted.
Example #1 QuickHashIntStringHash::delete() example
<?php
$hash = new QuickHashIntStringHash ( 1024 );
var_dump ( $hash -> exists ( 4 ) );
var_dump ( $hash -> add ( 4 , "five" ) );
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)
