Previous Comments: ------------------------------------------------------------------------ [2016-02-04 16:53:46] cmb@php.net Do you still experience this issue with recent PHP versions? If so, please make sure that the file really does exist and is readable, i.e. <?php $i = "***FILENAME***"; var_dump(is_readable($i)); // add this line $image = exif_thumbnail($i, $width, $height, $type); // … ?> If the function still fails randomly, we'd need a sample image file to be able to reproduce the issue. ------------------------------------------------------------------------ [2014-01-20 10:36:12] staviq at gmail dot com EDIT 2: It got event stranger, if i call this script from CLI results are CORRECT most of the time, but if the same script is called from apache ( as http request ) result is most of the time INCORRECT. ------------------------------------------------------------------------ [2014-01-20 10:27:32] staviq at gmail dot com EDIT: Inconsistent results are given for the same file, i might add. ------------------------------------------------------------------------ [2014-01-20 10:20:37] staviq at gmail dot com Description: ------------ All EXIF related function randomly out of nowhere return: Warning: exif_thumbnail(***FILENAME***): File too small (0) in ***SCRIPTNAME*** on line XXX Sometimes function like "exif_thumbnail", or "exif_read_data" will give me expected result, like a tumbnail or array of properties, but most of the time ( about 90% ) it will give me mentioned error. Tried on php 5.5.6 ( XAMPP bundled ) and 5.5.8 ( downloaded from php.net, used with nginx ) Test script: --------------- <? $i = "***FILENAME***"; $image = exif_thumbnail($i, $width, $height, $type); if( max( $width, $height ) == $width ) { $w = 256; $h = 256*( $height/$width ); } else { $h = 256; $w = 256*( $height/$width ); } echo "<img style=\"width: ".$w."px; height: ".$h."px;\" src='data:image/jpeg;base64,".base64_encode($image)."'>"; ?> Expected result: ---------------- Consistent result, either error every time, or expected thumbnail every time. Actual result: -------------- Warning: exif_thumbnail(P1030005.JPG): File too small (0) in E:\xampp\htdocs\t3.php on line 3 Warning: Division by zero in E:\xampp\htdocs\t3.php on line 7 ------------------------------------------------------------------------ -- Edit this bug report at https://bugs.php.net/bug.php?id=66519&edit=1
