px_create_fp -- Create a new paradox database Description
Create a new paradox database file. The actual file has to
be opened before with fopen(). The first parameter is the return
value of px_new(). fielddesc is an array containing
one element for each field containing is specification. Each field
specification is an array itself with either two or three elements.
The first element is always a string values used as the name of field.
It may not be larger than ten characters. The second element contains
the field type which is one of the constants listed in table Constants for field types.
In the case of a
character field, you will have to provide a third element specifying
the length of the field.
Замечание: This function is highly experimental, due to insufficient
documentation of the paradox file format. Database files created
with this function can be opened by px_open_fp()
but probably cannot be opened by the Paradox software.
Пример 1. Creating a Paradox database with two fields
<?php
if(!$pxdoc = px_new()) {
/* Error handling */
}
$fp = fopen("test.db", "w+");
$fields = array(array("col1", "S"), array("col2", "I"));
if(!@px_create_fp($pxdoc, $fields, $fp)) {
/* Error handling */
}
px_set_tablename($pxdoc, "testtable");
for($i=-50; $i<50; $i++) {
$rec = array($i, -$i);
px_put_record($pxdoc, $rec);
}
px_close($pxdoc);
px_delete($pxdoc);
fclose($fp);
?>
