QuickHashIntStringHash::add()
(PECL quickhash >= Unknown)
This method adds a new entry to the hash
说明
public QuickHashIntStringHash::add(int $key,string $value): bool
This method adds a new entry to the hash, and returns whether the entry was added. Entries are by default always added unless QuickHashIntStringHash::CHECK_FOR_DUPES has been passed when the hash was created.
参数
- $key
The key of the entry to add.
- $value
The value of the entry to add. If a non-string is passed, it will be converted to a string automatically if possible.
返回值
TRUE
when the entry was added, and FALSE
if the entry was not added.
范例
Example #1 QuickHashIntStringHash::add() example
<?php echo "without dupe checking\n"; $hash = new QuickHashIntStringHash( 1024 ); var_dump( $hash->exists( 4 ) ); var_dump( $hash->get( 4 ) ); var_dump( $hash->add( 4, "twenty two" ) ); var_dump( $hash->exists( 4 ) ); var_dump( $hash->get( 4 ) ); var_dump( $hash->add( 4, "twelve" ) ); echo "\nwith dupe checking\n"; $hash = new QuickHashIntStringHash( 1024, QuickHashIntStringHash::CHECK_FOR_DUPES ); var_dump( $hash->exists( 4 ) ); var_dump( $hash->get( 4 ) ); var_dump( $hash->add( 4, "seventy eight" ) ); var_dump( $hash->exists( 4 ) ); var_dump( $hash->get( 4 ) ); var_dump( $hash->add( 4, "nine" ) ); ?>
以上例程的输出类似于:
without dupe checking bool(false) bool(false) bool(true) bool(true) string(10) "twenty two" bool(true) with dupe checking bool(false) bool(false) bool(true) bool(true) string(13) "seventy eight" bool(false)
