php - fread(): supplied argument is not a valid stream resource -

this driving me little mad, thought perhaps server config issue, have tried on different host , same issue.

i have narrowed down , created test script rule out

<?php $myfile = "test.txt"; $fh = fopen($myfile, 'r') || die("couln't open file"); if ( $fh == true ) {         echo "file handle valid<br>"; } else {         echo "file handle invalid<br>"; } $thedata = fread($fh, filesize($myfile)) || die("couldn't read file"); echo $thedata; fclose($fh)|| die("couldn't close file"); ?> 

when test.txt missing correctly die couldn't open file when test.txt there

warning: fread(): supplied argument not valid stream resource in

i have set test.txt 777 sure

i wrote double check, works fine

<?php $data = file_get_contents('test.txt'); echo $data; ?> 

hopefully can shed light on me.

$fh = fopen($myfile, 'r') || die("couln't open file"); 

you assigning boolean expression $fh, losing actual file handle in process. try changing above line to

($fh = fopen($myfile, 'r')) || die("couln't open file");
