Handling Reading/Writing Files in PHP? -

it's been while since i've touched php, , i've been working in c# while. need file reading/writing, i'm not sure start. i've been spoiled visual studio's code-completion , real-time error checking, , it's bit hard going on such weakly-typed language.

in php, what's returned when reading file, , needs written when writing?

i need work file in hex, decimal fine too. there way read in way string?

there several ways read , write files:

you can create handler fopen() function.

the other way file_get_contents(), function returns content. , file_put_contents() set info file.

as illustration of handler, here logging stuff:

if (!is_writable($this->file) && $name !== self::core_log) { self::getinstance(self::core_log)->log(sprintf('couldn\'t write file %s. please, check file credentials.', $name)); } else { $this->handler = fopen($this->file, 'a+'); self::$instances[$name] = &$this; } ... if ($this->handler) fwrite($this->handler, '[' . date('r') . '] : ' . $l . "\n"); ... if ($this->handler) fclose($this->handler);

here can read , filesystem managment functions

php file

How do I check if an insert was successful with MySQLdb in Python? - i have code: cursor = conn.cursor() cursor.execute(("insert new_files (videos_id, filename, " "is_processing) values (%s,%s,1)"), (id, filename)) logging.warn("%d", cursor.rowcount) if (cursor.rowcount == 1): logging.info("inserted values %d, %s", id, filename) else: logging.warn("failed insert values %d, %s", id, filename) cursor.close() fun is, cursor.rowcount always one, though updated database create videos_id unique key. is, insert fails because in tests same videos_id going appear (and when check database, nil inserted). whatever reason, rowcount 1 - logging.warn have spits out rowcount of 1. so, question: can utilize rowcount work out if insert went fine? if so, (presumably) doing wrong? otherwise, how check if insert went fine? your code not commit after modifications (your modifications rolled back). should...
