note 79169 added to language.operators.arithmetic

Here's a slick little trick, very useful for CLI scripts to show processing taking place with a spinner... #!/usr/bin/php -q <?php //because I'm slick like that, we'll use some fancy ASCII escape codes. //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"; ?> ---- Server IP: 208.69.120.35 Probable Submitter: 67.168.161.74 ---- Manual Page -- http://www.php.net/manual/en/language.operators.arithmetic.php Edit -- https://master.php.net/note/edit/79169 Del: integrated -- https://master.php.net/note/delete/79169/integrated Del: useless -- https://master.php.net/note/delete/79169/useless Del: bad code -- https://master.php.net/note/delete/79169/bad+code Del: spam -- https://master.php.net/note/delete/79169/spam Del: non-english -- https://master.php.net/note/delete/79169/non-english Del: in docs -- https://master.php.net/note/delete/79169/in+docs Del: other reasons-- https://master.php.net/note/delete/79169 Reject -- https://master.php.net/note/reject/79169 Search -- https://master.php.net/manage/user-notes.php
