Here, I modified the template class I use for my site (very simple) to
do what you want. You need to have a template file that looks exactly
like what you wrote above (EXACTLY), nothing more. Here is a usage
example:
identifyTemplate('/path/to/file/above');
// set the parameters
$template->setParameter('firstname', $firstname);
$template->setParameter('product', $product);
$template->setParameter('date', $date);
$template->setParameter('expectation', $expectation);
// generate the output string and store in $outputStr
$outputStr = $template->createOutput();
// free memory occupied by the Template object instance
unset($template);
// print our data
print($outputStr);
Here is the class definition:
class Template
{
/**
* @var template
*/
var $template;
/**
* @var finalOutput
*/
var $finalOutput;
/**
* @var parameters
*/
var $parameters = array();
/**
* identifyTemplate
*
* determine which file to use for a template
*
* @access public
* @param string $template path to a template file
*/
function identifyTemplate($template)
{
$this->template = $template;
}
/**
* setParameter
*
* specify a name and a value to swap with that name
*
* this method can be called as many times as you have
* parameters.
*
* @access public
* @param string $name a parameter name
* @param string $value value of the parameter
*/
function setParameter($variable, $value)
{
$this->parameters[$variable] = $value;
}
/**
* createPage
*
* substitute parameter values where parameter names are found
*
* @access public
* @return string template combined with values (transformed)
*/
function createOutput()
{
// read the template into an array, then
// generate a string from that array
$this->finalOutput = implode("", (file($this->template)));
// loop though all the parameters, and
// set the variables from the file to
// their corresponding values
foreach ($this->parameters as $key => $value) {
$template_name = '[' . $key . ']';
$this->finalOutput = str_replace($template_name, $value,
$this->finalOutput);
}
return $this->finalOutput;
}
}

RE: [PHP] find and replace in php
Nothing will be inserted if the variable is empty, so you could just use $firstname, $product, $date, etc. inside your "letter". The main problem is adding logic to your "letter" to respond appropriately based on the value of different variables. For example: $MailBody = ""; if (empty($firstname)) $MailBody .= "Dear Customer"; else $MailBody .= "Dear $firstname"; Note the use of .= to append to the string. -Original Message- From: Henry [mailto:[EMAIL PROTECTED]] Sent: Tuesday, July 02, 2002 10:53 AM To: [EMAIL PROTECTED] Subject: [PHP] find and replace in php Imagine I have a piece of text "Dear [firstname] Thankyou for purchasing [product] on [date]. We're sure you'll be very [expectation]. Ta Very much." Whats the easiest way to replace all the things in square brackets with variables of the same name. i.e. $firstname, $product, $date, $expectation Whilst ensuring that if the variable doesn't exist then it will be replaced with "" (absolutely nothing).
