bits of code I always forget
howto store data in object instead of array
howto - read command line arguments
<syntaxhighlight> <?php echo count($argv); if (count($argv)<2){ //if no command line argument echo("script requires command line argument with name of db to backup"); exit(); } $db = $argv[1]; ?> </syntaxhighlight>
howto MYSQL -> JSON
<syntaxhighlight> $sth = mysql_query("SELECT ..."); $rows = array(); while($r = mysql_fetch_assoc($sth)) {
$rows[] = $r;
} print json_encode($rows); </syntaxhighlight>
howto see if a character is in a string
you need the ! to test if $somechar==";" (strcmp returns 0 if true)
- if(!strcmp($somechar, ";")) {
- as seen in assess/wikiquiz/wikivo2db.php
to get from text area w/o losing linebreaks
- $apage=nl2br(stripslashes($_POST[apage]));
to iterate through the lines in a string
- foreach (preg_split("/(\r?\n)/", $apage) as $line)
howto - populate multi-dimensional arrays
/*multi-dimensional arrays */
$a = array();
$a[0][0] = "a";
$a[0][1] = "b";
$a[1][0] = "y";
$a[1][1] = "z";
$firephp->log($a, 'nearrtest');
