QuickHashIntSet::add

(PECL quickhash >= Unknown)
This method adds a new entry to the set
public bool QuickHashIntSet::add ( int $key )

This method adds a new entry to the set, and returns whether the entry was added. Entries are by default always added unless QuickHashIntSet::CHECK_FOR_DUPES has been passed when the set was created.

Parameters:
key

The key of the entry to add.

Returns:

TRUE when the entry was added, and FALSE if the entry was not added.

Examples:
QuickHashIntSet::add() example
<?php
echo "without dupe checking\n";
$set = new QuickHashIntSet( 1024 );
var_dump( $set->exists( 4 ) );
var_dump( $set->add( 4 ) );
var_dump( $set->exists( 4 ) );
var_dump( $set->add( 4 ) );

echo "\nwith dupe checking\n";
$set = new QuickHashIntSet( 1024, QuickHashIntSet::CHECK_FOR_DUPES );
var_dump( $set->exists( 4 ) );
var_dump( $set->add( 4 ) );
var_dump( $set->exists( 4 ) );
var_dump( $set->add( 4 ) );
?>

The above example will output something similar to:

without dupe checking
bool(false)
bool(true)
bool(true)
bool(true)

with dupe checking
bool(false)
bool(true)
bool(true)
bool(false)
