Here's a nifty function to copy a whole table to another table. Takes as its arguments
$z -> the result of a SQL query with columns matching the table you're copying into.
$toTable -> string name of the table to copy into.
$link_identifier -> the db resource of the table you're copying into.
If anyone can find a faster way to do this, I'd be glad to know about it...
<?php
function mysql_multirow_copy($z,$toTable,$link_identifier) {
$fields = "";
for ($i=0;$i<mysql_num_fields($z);$i++) {
if ($i>0) {
$fields .= ",";
}
$fields .= mysql_field_name($z,$i);
}
$q = "INSERT INTO $toTable ($fields) VALUES";
$c = 0;
mysql_data_seek($z,0); //critical reset in case $z has been parsed beforehand. !
while ($a = mysql_fetch_assoc($z)) {
foreach ($a as $as) {
$a[key($a)] = addslashes($as);
next ($a);
}
if ($c>0) {
$q .= ",";
}
$q .= "('".implode(array_values($a),"','")."')";
$c++;
}
$q .= ";";
$z = mysql_query($q,$link_identifier);
return ($q);
}
?>
