ocicolumnsize() returns the size of the column as given by Oracle. You can either use the column-number (1-Based) or the column-name for the column parameter.
<?php
$conn = OCILogon("scott", "tiger");
$stmt = OCIParse($conn,"select * from emp");
OCIExecute($stmt);
print "<TABLE BORDER=\"1\">";
print "<TR>";
print "<TH>Name</TH>";
print "<TH>Type</TH>";
print "<TH>Length</TH>";
print "</TR>";
$ncols = OCINumCols($stmt);
for ( $i = 1; $i <= $ncols; $i++ ) {
$column_name = OCIColumnName($stmt,$i);
$column_type = OCIColumnType($stmt,$i);
$column_size = OCIColumnSize($stmt,$i);
print "<TR>";
print "<TD>$column_name</TD>";
print "<TD>$column_type</TD>";
print "<TD>$column_size</TD>";
print "</TR>";
}
print "</TABLE>";
OCIFreeStatement($stmt);
OCILogoff($conn);
