$placeholders = array(‘offspring’, ‘pronoun’, ‘pronoun2’, ‘sex’); Notes

//male replace values array
$malevals = array(‘son’, ‘he’, ‘him’, ‘boy’);

//female replace values array
$malevals = array(‘son’, ‘he’, ‘him’, ‘boy’);

//female replace values array
$femalevals = array(‘daughter’, ‘she’, ‘her’, ‘girl’);

//male string

$malestr = str_replace($placeholders, $malevals, $rawstring);

//female string
$femalestr = str_replace($placeholders, $femalevals, $rawstring);

echo “Son: “. $malestr . “<br />”;

8.9 Summary

• PHP has a range of functions that handle date and time. Some of these functions work
with a so-called Unix timestamp, which is the number of seconds since January 1, 1970
at 00:00:00 GMT.
• The easiest way of obtaining the current time is with the time( ) function.
• The opposite of formatting text is parsing a textual description of a date into a timestamp.
The strtotime() function handles many different formats.
• Strings in PHP are a sequence of characters that are always internally null terminated.
• Individual characters in a string can be accessed using the $str{offset} notation.
