codeigniter - PHP - concatenate string from database -


i have string send email registration. string stored in database.

when load string model.

//string db hi {$email} , bla bla bla

my controllers example.

  function (){       $text = $this->some_model->get_string();        // var post       $email = 'foo@mail.com'       echo $text;   }

and there no change whatsoever in string. str_replace cant output this.

hi foo@mail.com, bla bla bla

what if case. have 2 or more string replace?

example

 hi {$email}, {$username}

php doesnt magically check each string if contains code can execute. if string in database contains hi {$email} , bla bla bla php leave that.

so need manually override values in string match values. safest way simple str_replace

<?php $string = 'hi {$email} , bla bla bla'; $email = 'foo@example.com'; $output = str_replace('{$email}', $email, $string); $output = str_replace('{$username}', $username, $output ); echo $output; //hi foo@example.com , bla bla bla ?>

or in code

<?php function (){     $text = $this->some_model->get_string();     $email = 'foo@mail.com';     echo str_replace('{$username}', $username, str_replace('{$email}', $email, $text));    //hi foo@mail.com , bla bla bla } ?>

if create string (with double quotes) before put in database, value of {$email} have been changed

<?php $email = 'foo@mail.com'; $text = "hi {$email} , bla bla bla"; //notice double quotes, single qoutes wont work echo $text; //hi foo@mail.com , bla bla bla ?>
