QuickHashIntStringHash::add — This method adds a new entry to the hash
$key
, string $value
) : boolThis 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.
keyThe key of the entry to add.
valueThe value of the entry to add. If a non-string is passed, it will be converted to a string automatically if possible.
TRUE when the entry was added, and FALSE if the entry was not added.
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)
