| For 2023 (and 2024 ...) - we are now fully retired from IT training. We have made many, many friends over 25 years of teaching about Python, Tcl, Perl, PHP, Lua, Java, C and C++ - and MySQL, Linux and Solaris/SunOS too. Our training notes are now very much out of date, but due to upward compatability most of our examples remain operational and even relevant ad you are welcome to make us if them "as seen" and at your own risk. Lisa and I (Graham) now live in what was our training centre in Melksham - happy to meet with former delegates here - but do check ahead before coming round. We are far from inactive - rather, enjoying the times that we are retired but still healthy enough in mind and body to be active! I am also active in many other area and still look after a lot of web sites - you can find an index ((here)) |

PHP fread - truncated data
Note that PHP's fread function returns the number of bytes you request as the second parameter ...OR the number of remaining bytes if it's less than the number you give ... or 8192 bytes, even if there's more than that available and you've requested more. I got caught out by this one earlier today ... felt that it was useful (re)minder to post it up here. If you need to read more that 8k into a variable: while ($info = fread($fh,8192)) { (written 2007-02-27, updated 2007-02-28) Associated topics are indexed as below, or enter http://melksh.am/nnnn for individual articles H109 - PHP - Input / Output[114] Relative or absolute milkman - (2004-11-10) [616] printf - a flawed but useful function - (2006-02-22) [653] Easy feed! - (2006-03-21) [709] Handling huge data files in PHP - (2006-05-04) [997] Most recent file in a directory - PHP - (2006-12-18) [1096] Sample script - FTP to get a file from within PHP - (2007-03-01) [1113] File and URL reading in PHP - (2007-03-20) [1442] Reading a file multiple times - file pointers - (2007-11-23) [1780] Server overloading - turns out to be feof in PHP - (2008-09-01) [2964] An introduction to file handling in programs - buffering, standard in and out, and file handles - (2010-09-21) [3029] PHP data sources - other web servers, large data flows, and the client (browser) - (2010-11-04) [3159] Returning multiple values from a function call in various languages - a comparison - (2011-02-06) [3424] Divide 10000 by 17.
