oci_bind_array_by_name — Binds a PHP array to an Oracle PL/SQL array parameter
$statement
   , string $name
   , array &$var_array
   , int $max_table_length
   [, int $max_item_length = -1
   [, int $type = SQLT_AFC
  ]] )
   Binds the PHP array var_array to the Oracle
   placeholder name, which points to an Oracle PL/SQL
   array. Whether it will be used for input or output will be determined at
   run-time. 
  
statementA valid OCI statement identifier.
nameThe Oracle placeholder.
var_arrayAn array.
max_table_lengthSets the maximum length both for incoming and result arrays.
max_item_lengthSets maximum length for array items. If not specified or equals to -1, oci_bind_array_by_name() will find the longest element in the incoming array and will use it as the maximum length.
typeShould be used to set the type of PL/SQL array items. See list of available types below:
          SQLT_NUM - for arrays of NUMBER.
         
          SQLT_INT - for arrays of INTEGER (Note: INTEGER
          it is actually a synonym for NUMBER(38), but
          SQLT_NUM type won't work in this case even
          though they are synonyms).
         
          SQLT_FLT - for arrays of FLOAT.
         
          SQLT_AFC - for arrays of CHAR.
         
          SQLT_CHR - for arrays of VARCHAR2.
         
          SQLT_VCS - for arrays of VARCHAR.
         
          SQLT_AVC - for arrays of CHARZ.
         
          SQLT_STR - for arrays of STRING.
         
          SQLT_LVC - for arrays of LONG VARCHAR.
         
          SQLT_ODT - for arrays of DATE.
         
   Returns TRUE on success or FALSE on failure.
