Using javascript regular expressions to stop users from entering non-aphanumeric characters or white spaces Say you want to stop users from entering non-aphanumeric characters or white spaces. Using regular expressions would be the easiest method: Here is my javascript code: For numbers only use /^[0-9]+$/ For mixed text and numbers, with spaces /^[0-9a-zA-Zs]+$/ Here are more useful regular expressions:

[a-zA-Z] any letter
d any number; same as [0-9]
D any NOT number; same as [^0-9]
w any alphanumeric character; same as [a-zA-Z-0-9_]
W any NON-alphanumeric character; same as [^a-zA-Z0-9_]
s any whitespace (tab, space, newline, etc...)
S any NON-whitespace
n newline
t tab

Portion() function for trimming text

Returns the portion of text specified by the start and length parameters. This help to trim text down for display in a small area or to give a sample of a larger body of text. I created this function to display a portion of listings on my home page under their related links to the full body of content. This can helps your visitor to find the content faster as well as helps search engine better index your web site. Portion() Code:

  $max_len){
echo substr("$str", 0, $max_len)."..."; // your portion of text with trailing dots "..."
}
else
echo $str;
}
// function code end here

$str = "Hello World"; // edit or delete this line for your use
portion(7,"$str"); // call the function ( this will return "Hello W..." )

?>

PHP strip remove white space from end of string

Need to remove the white space at the end of a string before recording the data. Use PHP's rtrim(). rtrim(): rtrim is great for deleting that unwanted space at then end of strings. The perfect example for using this function is when receiving data from an online form and, at the end of a data field, some one leaves an extra white space. This white space means nothing and you want to delete it. rtrim() to the rescue. Example:

Other Examples: You can also trim down a string by matching words or letters and the end of a string. Example:

// Example 1: Character-by-character comparison match.

echo rtrim('This is a test test code', 'test code');
// returns 'This is a'

// Example 2: matches the last whole word with half the letters

echo rtrim('This is a test', 'est');
// returns 'This is a'
?>
