QuickHashIntStringHash::add

(PECL quickhash >= Unknown)

QuickHashIntStringHash::add — This method adds a new entry to the hash

说明

public bool QuickHashIntStringHash::add ( int $key , string $value )

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)
