php - How do I update the source code with mamp? -

-

i downloaded mamp 3 php 5.5.10. created new file php , put in htdocs folder , displayed correctly in chrome. added html , displayed nothing. checked source code , had 1 blank line. how fix displays html , php? also, why happen?

initial php was

<?php echo 'hi';?>

then changed 

<!doctype html> <html> <head> <title>food</title> </head> <body> <?php  echo 'hi'; ?> <form method="post" <?php echo "action=\"$_server['php_self']\"";?>> <input type="text" name="food" placeholder="enter food name"> <input type="submit" value="submit"> </form> </body> </html>

this line goofy:

<form method="post" <?php echo "action=\"$_server['php_self']\"";?>>

change to:

<form method="post" action="<?php echo $_server['php_self'];?>">

chances don't have error reporting turned on. otherwise you'd see this:

parse error: syntax error, unexpected '' (t_encapsed_and_whitespace), expecting identifier (t_string) or variable (t_variable) or number (t_num_string) in /applications/mamp/htdocs/test/index.php on line 10

turn on error reporting:

open /applications/mamp/bin/php/{your php version}/conf/php.ini.

find display_errors = off (around line 277) , change display_errors = on.

restart mamp.

php - render data via PDO::FETCH_FUNC vs loop -

-
i've been using 2 methods render data. the first one: function name($id,$name){ return '<div id="'.$id.'">'.$name.'</div>'; } echo implode($pdo->query("select id,name user")->fetchall(pdo::fetch_func,'name')); the second one: $users = $pdo->query("select id,name user")->fetchall(pdo::fetch_obj); foreach($users $user){ echo name($user->id,$user->name); } i don't understand how pdo::fetch_func works. tried figure out. however, not well-documented. could please explain fetch mode? , also, 1 performs better? thank you. both methods wrong , have learn how use templates , how separate business logic presentation logic. $users = $pdo->query("select id,name user")->fetchall(pdo::fetch_obj); tpl::assign('users', $users); is code business logic part. then in template <?php foreach $users $row): ?> <div id="<?=$...
