Why Would I Want to Use Email with PHP?<\/h3>\n

PHP is a useful website building tool. It gives the website the ability to automatically run scripts when a button is pushed or someone interacts with a particular part of a site.<\/span><\/p>\n

Using PHP to send emails is often used for forms embedded on the site. When the form is filled and submitted, the PHP script will run, grab the information from the form, and send out an email. <\/span><\/p>\n

Depending on how you configure your script, that email can be anything from a forwarded message to you to a greeting to the person who submitted the information.<\/span><\/p>\n

<\/a><\/p>\n

Where Do I Put PHP Script?<\/h3>\n

The PHP script will go into your site\u2019s HTML, usually within the <\/span><body> <\/span>element.<\/span><\/p>\n

<\/a><\/p>\n

How Do I Send Email with PHP?<\/h3>\n

Check out PHP.net\u2019s <\/span>mail function documentation<\/span><\/a>.<\/span><\/p>\n

If you would like some examples, see W3schools <\/span>PHP mail function explanation<\/span><\/a>.<\/span>

<\/a><\/p>\n

CRLF<\/h4>\n

CRLF stands for \u201cCarriage Return Feed Line,\u201d which signals the end of a line. CLRF is written as <\/span>\\r\\n<\/span>.<\/span><\/p>\n

<\/a><\/p>\n

Common Use Examples<\/h4>\n
To send a message to a specific email address:<\/h5>\n
<?php<\/span>\r\n\r\n$message = \u201cNew customer.\\r\\nGo to thisSite.com to see new customer info.\\r\\nThanks,\\r\\nSite Team\u201d;<\/span>\r\n\r\nmail(\u2018<\/span>myEmail@example.com<\/span><\/a>\u2019, \u2018Email Subject\u2019 , $message);<\/span>\r\n\r\n?><\/span><\/pre>\n
If the message is longer than 70 characters:<\/h5>\n
<?php<\/span>\r\n\r\n<\/a>\r\n$message = \u201cThis is a message longer than seventy characters. Use wordwrap below to make things work.\u201d;<\/span>\r\n\r\n$message = wordwrap($message, 70, \u201c\\r\\n\u201d);<\/span>\r\n\r\nmail(\u2018<\/span>myEmail@example.com<\/span><\/a>\u2019, \u2018Email Subject\u2019 , $message);<\/span>\r\n\r\n?><\/span><\/pre>\n
If the email has multiple headers:<\/h5>\n
<?php<\/span>\r\n\r\n$to = \u2018<\/span>username@example.com<\/span><\/a>\u2019;<\/span>\r\n\r\n$subject = \u2018Email Subject\u2019;<\/span>\r\n\r\n$message = \u2018Your message will go here.\\r\\nDon\u2019t forget the CRFL for lines\\r\\n\u2019;<\/span>\r\n\r\n$headers = \u2018From: <\/span>exampleCompany@example.com<\/span><\/a>\u2019 . \u201c\\r\\n\u201d .<\/span>\r\n\r\n\u2018Reply-To: <\/span>exampleCompany@example.com<\/span><\/a>\u2019 . \u201c\\r\\n\u201d .<\/span>\r\n\r\nmail($to, $subject, $message, $headers);<\/span>\r\n\r\n?><\/span><\/pre>\n

Using the Filter Function for Forms<\/h3>\n
Using the Filter Function for Forms<\/span><\/p>\n
If you are using this in a form, you should use the filter function. Filters are used to \u201csanitize\u201d or validate data that comes through your form. <\/span><\/p>\n
Email forms are a common target for abuse. It\u2019s no problem if the user enters information as they are supposed to, but sometimes they can do things that break the script. <\/span><\/p>\n
Filters help with that. For example, if a user inputs an invalid character into an email, you can use the filter function with an if-else statement to make sure the email is valid. Check out W3School\u2019s <\/span>PHP filter explanation<\/span><\/a> to learn more about filters.<\/span><\/p>\n
Example:<\/p>\n
If the input from a form was:<\/p>\n
\u00a0email@@example.com<\/pre>\n
You would use this code to filter any invalid characters in the address. In this case, the second \"@\" is invalid.<\/p>\n
<?php<\/span>\r\n\r\n\/\/ form populates variable with user email <\/span>\r\n\r\n$email = \"email@@example.com\";<\/span>\r\n\r\n\r\n\r\n\r\n\/\/ Checks email for invalid characters<\/span>\r\n\r\nif (<\/span>filter_var<\/span>($email, <\/span>FILTER_VALIDATE_EMAIL<\/span>)) {<\/span>\r\n\r\n \u00a0\u00a0\u00a0echo(\"$email is a valid email address.\");<\/span>\r\n\r\n} else {<\/span>\r\n\r\n \u00a0\u00a0\u00a0echo(\"$email is not a valid email address.\");<\/span>\r\n\r\n}<\/span>\r\n\r\n?><\/span><\/pre>\n
The output would be:<\/p>\n
email@@example.com is not a valid email address.<\/pre>\n
 <\/p>\n
filter_var()<\/span> initiates the filter function, and then you can use a filter constant to tell <\/span>filter_var()<\/span> what you want to filter. <\/span><\/p>\n
Check out PHP\u2019s <\/span>list of filter constants<\/span><\/a>. This\u00a0list gives you an idea of <\/span>filter_var()<\/span> uses. Correct usage of <\/span>filter_var()\u00a0<\/span>can protect your form from user error and keep your PHP scripts running smoothly. <\/span><\/p>\n
