java - Use array element as termination in for loop -


please explain loop:

for(p=0;p<a[j];p++)

i beginner , confused how such loops work?

please emphasize on use of a[j] in loop.

if a[j] remains constant positive number through each iteration of for loop, loop run a[j] times, a[j] evaluates integer (or long, can't tell code posted). of course a[j] (or j) modified inside loop. in case, loop terminates once p greater or equal a[j] when loop condition evaluated. condition checked before each iteration of loop. if a[j] 0 or negative number, contents of for loop never executed. loop can exit prematurely @ time if there call break or return within loop.

while using php cli in ubuntu got apache web server cant read file can while using in browser. , error shows nothing , next used code testing purposes : <? $handle = fopen("testfile.txt", "r"); if ($handle) { while (($buffer = fgets($handle, 4096)) !== false) { echo $buffer; } if (!feof($handle)) { echo "error: unexpected fgets() fail\n"; } if(!is_readable($handle) { die("not readable"); } fclose($handle); } ?> how fix ? edit : after removing '@' before fopen got following error fopen(testfile.txt): failed open stream: no such file or directory in /var/www/log/ka.php on line 2 when run script through cli, uses shell's working directory, in opposition file's directory (which apache hands current directory). important you, since fopen call depends on relative path; , relative paths resolved relatively working directory, not script. to have script behave apache, eit...
