Bug #76814 [NEW]: file_get_contents fail when maxlen is given null value

From: adrien dot blandin at gmail dot com Operating system: Debian PHP version: 7.1.21 Package: Filesystem function related Bug Type: Bug Bug description:file_get_contents fail when maxlen is given null value Description: ------------ Signature of file_get_contents is ($filename, $use_include_path = false, $context = null, $offset = 0, $maxlen = null) so null is an allowed value for maxlen. Yet, when I explicitly gave the default values in my call: file_get_contents($filename, false, null, 0, null), no content is found. If I call the function with only the filename (so default values will be used too), content is found. If I explicitly gave default values for all parameters except maxlen, content is found. Test script: --------------- echo 'default: ' . strlen(file_get_contents($filename)) . PHP_EOL; echo 'without maxlen: ' . strlen(file_get_contents($filename, false, null, 0)) . PHP_EOL; echo 'with maxlen: ' . strlen(file_get_contents($filename, false, null, 0, null)) .
