My fellow web geeks might find this script, php-check<\/b> download home on the range movie<\/a><\/em> , useful. It recursively scans a directory checking PHP files for syntax errors.<\/p>\n

Just copy it somewhere in your path (like \/usr\/local\/bin<\/code>) and chmod it to 755. <\/p>\n

I wrote the script because I edit PHP using Notepad++<\/a>, so it\u2019s easy for small typos to enter my scripts. I needed a quick way to scan a directory after uploading revised files.
\nI wrote it in PHP so that those who need it will also know how to customize it.<\/p>\n

\nif ($argc!=2) {

\n}<\/p>\n

if (!is_dir($argv[1])) {

$counter=scan_dir($argv[1]);<\/p>\n

This is a quick and dirty script \u2014 there are probably some bugs in it. User beware. <\/p>\n

If you find it helpful, you might also want to check out scripts like PHP CodeSniffer<\/a> <\/p>\n
