PHP arrays in arrays
PHP question...
I have an SQL query that's pulled back user IDs as a set of columns. Rather than IDs, I want to use their names.
So I have an array of columns $col with values 1,7,3,12 etc and I've got an array $person with values "Fred", "Bert", "Tom" etc
So what I want to do is display the $col value but the person's name, not the id...
ie
$person[$col[1]] should display "Fred"
$person[$col[3]] should display "Tom"
etc
However, this doesn't want to parse correctly and I get errors, with or without quotes. I've verified that $col[1] is 1 and $person[1] is "Fred", for example. What syntax is required?
Any help appreciated.

OCI_BIND_ARRAY_BY_NAME(3) OCI_BIND_ARRAY_BY_NAME(3)
oci_bind_array_by_name - Binds a PHP array to an Oracle PL/SQL array parameter
SYNOPSIS
bool oci_bind_array_by_name (resource $statement, string $name, array &$var_array, int $max_table_length, [int $max_item_length = -1],
[int $type = SQLT_AFC])
DESCRIPTION
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.
PARAMETERS
o $statement
- A valid OCI statement identifier.
o $name
- The Oracle placeholder.
o $var_array
- An array.
o $max_table_length
- Sets the maximum length both for incoming and result arrays.
o $max_item_length
- Sets maximum length for array items. If not specified or equals to -1, oci_bind_array_by_name(3) will find the longest element
in the incoming array and will use it as the maximum length.
o $type
- Should be used to set the type of PL/SQL array items. See list of available types below:
o SQLT_NUM - for arrays of NUMBER.
o 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).
o SQLT_FLT - for arrays of FLOAT.
o SQLT_AFC - for arrays of CHAR.
o SQLT_CHR - for arrays of VARCHAR2.
o SQLT_VCS - for arrays of VARCHAR.
o SQLT_AVC - for arrays of CHARZ.
o SQLT_STR - for arrays of STRING.
o SQLT_LVC - for arrays of LONG VARCHAR.
o SQLT_ODT - for arrays of DATE.
RETURN VALUES
Returns TRUE on success or FALSE on failure.
