heh Jay, I have been playing with this ...
I rewrote your code abit (including removing the check for the string 'CHA'
- cos that was limiting my search too much ;-)
I made it recursive + a few other tweaks, haven't look into the proper guts of
'grep' action yet - would be nice to clean that up a little.
anyway another handy tool in the bag :-)
here is the code btw:
<?php
/*
* Query Finder
* Jay Blanchard
* August 2005
* NOT REALLY TOO EXTENSIBLE
*
* usage: call from command line, perform manual output to text file
* i.e. php qryfind.php > <nameOfFileToSave.txt>
*/
/* cruise the directory looking for PHP files */
function findTheQueries($theDirectory)
{
static $arrQueryStarters, $arrQueryStartersCnt, $dirSep;
if (!isset($arrQueryStarters)) {
$arrQueryStarters = array('SELECT ', 'INSERT ', 'UPDATE ', 'FROM ',
'EXECUTE ', 'WHERE ', 'ORDER BY ', 'LEFT JOIN ');
$arrQueryStartersCnt = count($arrQueryStarters);
// Determine OS specific settings
$uname = php_uname();
if (substr($uname, 0, 7) == "Windows") {
$dirSep = "\\";
} else if (substr($uname, 0, 3) == "Mac") {
$dirSep = "/";

$dirSep = "/";
}
}

echo "Searching for queries in php files in: $theDirectory\n";
if ($dh = opendir($theDirectory)) {

/* recurse subdirs */
if (is_dir($theDirectory.$dirSep.$theFile)) {

findTheQueries($theDirectory.$dirSep.$theFile);
