QuickHashIntStringHash::add — 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.

示例

示例 #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" ) );
?>

以上示例的输出类似于：

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)
