Here's a neat little trick to use ASCII escape codes to show processing in a CLI script.
#!/usr/bin/php -q
<?php
//http://www.cs.csubak.edu/Tables_Charts/VT100_Escape_Codes.html
define('ESC', 27);
printf( "%c[2J", ESC ); //clear screen
//note how the '-' is at [1], not [0]
$cursorArray =
array('/','-','\\','|','/','-','\\','|');
echo "Processing: ";
printf( "%c7", ESC ); //save cursor position
for ($count = 1; $count <= 30; $count++)
{
//note that $i is all self contained.
printf("%c8(".$cursorArray[ (($i++ > 7) ? ($i = 1) : ($i % 8)) ].") %02d",
ESC, $count); //restore cursor position and print
sleep(1);
}
echo "\nDone.\n";
?>
