Scripts
Okay, here are my scripts. I’ll have a lot more coming later as I write more tutorials. Enjoy these! Oh and don’t forget to include the header if by off-chance, you’ll use one of these.
PHP Error-Reporting
I want to stress that the logging capability of this script is just for fun. Use the error_log() function instead.
<?php

set_error_handler('error');
function error($type, $msg, $file, $line, $context) {
echo "<h1>Error!</h1>";
$date = date('l jS \of F Y h:i:s A');
echo "Here is the information provided by the script:";
echo "<hr><pre>";
//shows the error code
echo "Error code: $type<br />";
//error message
echo "Error message: $msg<br />";
//error in what file and what line
echo "Script name and line number of error: $file:$line<br />";
$variable_state = array_pop($context);
echo "Variable state when error occurred: ";
print_r($variable_state);
echo "</pre><hr><br>";
//logging the error
$dir = 'errors.txt ' or die ('Could not be found');
$open = fopen($dir,'a') or die ('Could not be opened');
fwrite($open, "
ERROR: $date
type: $type,
msg: $msg,
file: $file,
line: $line,
context: $context"
) or die ('Could not be written');
die ('Error has been logged<br>');
}

Custom E-mail Form
Here’s a custom e-mail form I created earlier.

}
// check whether input is alphabetic
function isAlpha($value) {
return preg_match('/^[a-zA-Z]+$/', $value);
}
function name ($var) {
if (!isset($var)){
return TRUE;

return TRUE;
