It works in PHP 5 and up. - -Our examples omit array() around function parameters and use dangling commas. -To get that, you can either use our just-in-time syntax converter or use -our patch for PHP (see http://cschneid.com/php/ for info). To use the syntax -converter, see the chapter about it_auto_prepend.php below. - -it_auto_prepend.php - ITools environment (optional) ---------------------------------------------------- -If you include this with the PHP auto_prepend_file ini setting you get the -following benefits: -a) Includes all the ITools functionality -b) auto_prepend.php is included for each directory in the include path. -c) Automatic syntax conversion is enabled if you have a vanilla PHP without -our syntax patch installed. -NOTE: This may need manual configuration on shared hosting -d) An autoloader for classes is installed, you don't need to require any files -it looks for foo.class if you access class foo). -e) $GLOBALS['IT_HOME'] is set to one level above the DOCUMENT_ROOT in web -mode, one level above the script for CLI mode: This allows access to data -directories from web and CLI mode alike. - -Example: - # Put this line in .htaccess or httpd.conf to set up ITools environment - php_value auto_prepend_file YOUR_PATH_TO_ITOOLS/it_auto_prepend.php - - -it_html - HTML output generation --------------------------------- -it_html creates a global function for each common html tag. Those functions -accept variable arguments, key=>value pairs are considered attributes. - -Example: - new it_html; # Not necessary if using it_auto_prepend.php - echo html( - head('title' => "welcome earth"), - body( - p('style' => "margin:1em", - a('href' => U("http://google.com/search", 'q' => "Hello World"), "Hello World"), - ), - ), - ); - -Functions: - new it_html($config) -- create global functions, choose (x)html style - div($attributes, $content) -- return a <div> with attributes and content - html($params, $content) -- return a <html> but adds correct doctype - head($params, $content) -- return a <head> but needs special params - select($tags, $options, $selected) -- build a html select from an array - tag($tag, $content) -- create arbitrary <$tag> - Q($str) -- html encode a value, roughly like htmlentities - U($arr) -- create a valid url from strings and key=>value - it_html::sanitize($html) -- remove dangerous tags from html code - - - -it_dbi - Database access ------------------------- -The dbi object is a simple mysql interface. For each table in your database, -a class is created automatically. Queries are encoded as arrays which ensures -correct quoting, see select(). Errors are by default reported within dbi. - -Example: - it_dbi::createclasses(); # Not necessary if using it_auto_prepend.php - $record = new T_Customers('ID' => 'mueller'); - $record->update('email' => "mueller@spam.com"); - $response = "Email added for $record->name"; - # Using Iterators (PHP 5+ only): - foreach (new T_Customers as $customer) { ... } # Iterate all customers - foreach (new T_Customers('age' => 42) as $customer) { ... } - foreach (new T_Customers as $id => $customer) { ... } # $id = $customer->_key - # ... you can iterate over any query (also multiple times): - $customers->select('age' => 42); - foreach ($customers as $customer) { foo($customer); } - foreach ($customers as $customer) { bar($customer); } - -Functions: - it_dbi::createclasses($config) -- create database objects for each table name - $t = new Tablename($query) -- return a dbi object, executes optional select - $t->select($query) -- read first result of (encoded) query into t. - $t->iterate() -- advance to next result - $t->update($fields) -- update selected record from key=>value pairs - $t->insert($fields) -- insert a new record from key=>value pairs - $t->replace($fields) -- replace a new record from key=>value pairs - $t->delete($query) -- delete current record or those found by query - $t->query($sqlquery) -- execute a raw SQL query on db connection - - - -it_text - Translation support ------------------------------ -it_text finds the best language to use from browser and override settings. It -then reads texts.php in the format documented in the constructor. You can then -use T() to translate a label. Unknown labels are reported using it::error() - -Example: - echo T('hello') . ' ' . Q($customer->name); - echo ET('chainletter', 'name' => Q($customer->name)); - -Functions: - new it_text($config) -- read texts. usually called implicitly - T($label) -- return translated $label - ET($label, $values) -- return translated $label w/ values replaced - T_lang() -- returns current language - T_set_language($language) -- sets a new language - T_exists($label) -- returns whether a label is defined - - - -it_debug - Debug support ------------------------- -it_debug is used for debugging. The function ED($foo, $bar) echoes the -values of $foo and $bar AND prepends it with the names of the variables. EDX() -does the same and exits. EDC('verbose', $foo) only echoes if -$GLOBALS['debug_verbose'] is set. it_debug::backtrace() outputs a compact -stackdump. - -Example: - ED($foo, $bar); # echoes name and value of $foo and $bar - EDC('verbose', $foo); - -Functions: - ED($args...) -- echoes names and values of all args - EDX($args...) -- echoes names and values of all args and exits - EDC('foo', $var...) -- echoes only if $GLOBALS['debug_foo'] is set - D($args...) -- returns formatted names and values of params - it_debug::backtrace($skip) -- prints short backtrace, skipping $skip levels - - - -it.class - Tool functions -------------------------- -it.class provides various statically callable functions. The main groups are: -a) Much simpler perl regex matching (no delimiters, matches returned directly -as scalar or array, case insensitive, locale support) and a multi-pattern -replacement function. -b) Better error functions: stack and variable dumps added to error messages, -error messages mailed if display_errors is off. Extra parameter allow the -filtering of sporadic errors. -c) Better shell support, specifically a command line parser and an exec -function that handles quoting. - -Example: - $from = it::match('From: (.*)', $mail); - $page = it::replace('<.*?>' => '', ' +' => ' ', $page); - it::error('title'=>"cannot connect", 'id'=>"db"); # suppress sporadic errors - it::fatal("internal error"); - $diff = it::exec("diff -wu {old} {new}", 'old' => $old, 'new' => $new); - it::imageconvert('in' => "src.jpg", 'out' => "dst.jpg", 'size' => "80x80"); - -Functions: - it::match($pattern, $subject, $opts) -- find pattern in subject using opts; return matches - it::replace($replace, $subject, $opts) -- replace patterns in subject; return result - it::error($info) -- print or mail error message - it::fatal($info) -- print or mail error message, then exit - it::bail($message) -- print message to stderr, exit with errcode - it::exec($command, $values) -- execute command, return output - it::getopt($usage) -- parse (or print) usage, return options, - it::gets() -- fetch next line from stdin or named arg - it::imageconvert($params) -- Convert image using ImageMagick convert - it::log($fn, $data, $data...) -- Append data (separated by tabs) to log/$fn-$date - it::map($expr, $array) -- Apply php expression to array members & return - - - -it_url - URL handling ---------------------- -Helper functions dealing with URLs. - -Example: - $filename = it_url::get_cache( - 'url' => "http://static.php.net/www.php.net/images/php.gif", - 'timeout' => 5, - 'cachedir' => $_SERVER['DOCUMENT_ROOT'] . "/cache", - ); - -Functions: - it_url::get($params) -- performs GET/POST requests to web servers - it_url::get_cache($params) -- performs GET/POST and caches the result - - -it_user - Session handling --------------------------- -This allows maintaining session cookies and authentication status for users. -Not documented yet, check the source. - -it_xml - XML parser -------------------- -This will parse an XML string and returns a tree of PHP objects; similar to -simplexml, supports a streaming mode for huge XML files. Not documented yet, -check the source. |
