Im fairly new to PHP, been reading for some time and copying things from books, but am just now trying to develop my own app.

 

I'm looking to take a line from my mySql database, see if there is an email address, and if so to save that. Some lines may have extra stuff in them like "hello bob john@hisdomain.com how are you".

 

My thought was to store each row as a string, then to explode that string into an array based off the " " (space). Then to test to see if a member of an array had the "@", if so to store that into another array, if not, to spit out "No Email address found".

 

Here is where I'm at. Any suggestions would be appreciated.

<html>

<head>

<title>Data Manipulation</title>

    <?php include 'header.php'; ?>

</head>

<body>

<h2>Email Address Extract</h2>

 

<?php

//convert email column to string

$result = mysql_query("SELECT email FROM users");

//array to store strings with @

$please=array();

 

while($row = mysql_fetch_array($result)) {

$address = (string)$row['email'];

$findme = '@';

$test1 =(explode(" ",$address));

$pos = strpos($test1, $findme);

 

if($pos === false) {

echo "No email address found<br />";

} else {

array_push($please,"$test1");

}

print_r ($please);

}

?>

   

   

</body>

</html>

$string = "hello bob johnhis@domain.com how are you";
$find = explode('@', $string);

if($find['1'] != ""){

echo "I have a @ in my string!";
}else{

echo "Doesnt have @ in string!";
}

Thanks for the suggestions but neither of those ended up doing quite what I'm looking for. I've made some modifications and think I am fairly close so I'll get really specific with where I'm at and see if anyone has any helpful suggestions. Here is the PHP piece of my code. I use the include function to store the connection to my database so just assume that's done correctly (b/c it is).

 

I think the real problem is if I am using the foreach function properly, as well as if attempting to search for the "@" symbol using the == operator. My comments are highlighted in orange so you can at least see my thought process.

 

I've been plugging at this for hours and just can't QUITE get it. Ideas appreciated.

<?php 
//convert email column to string
$result = mysql_query("SELECT email FROM users");
//create please array to store valid email addresses
$please=array();
$findme = "@";
//for each row of 'email' in table 'users'
 while($row = mysql_fetch_array($result)) {
	$address = (string)$row['email'];
//take the entire string and explode each word into array $words using the ' ' as a delimiter 
$words=array(explode(' ', $address));
//loop over $words applying its value to $value
foreach($words as $value) { 
//if the $value has $findme (the @)
if($value == "$findme"){
//echo $value and push it to $please array
echo "I have a @ in my string! <br />";
        array_push($please, "$value);

}else{

echo "Doesnt have @ in string! <br />"
        unset($value);
}
}
?>

Finally got it. Thanks for all the suggestions

 

<?php
$result = mysql_query("SELECT email FROM users");
$valid_Emails=array();
$findme = '@';
 while($row = mysql_fetch_array($result)) {
	$address = (string)$row['email'];
	$words=array(explode(' ', $address));


	foreach ($words as $value) 
		{
		$numofrows = count($value);
		for ($i = 0; $i < $numofrows; $i++) {
			if(strpos($value[$i],$findme) === false) {
			} else {
				echo "@ was found in " . $value[$i] . "<br />";
				array_push($valid_Emails, $value[$i]);	
			}
		}	
		}
 }

 $csv_file = implode(",", $valid_Emails);
?>
