Is there a Shortcut for
echo "<pre>";
print_r($myarray);
echo "</pre>";
It is really annoying typing those just to get a readable format of an array.
This is the shortest:
echo '<pre>',print_r($arr,1),'</pre>';
The closing tag can also be omitted.
Nope, you'd just have to create your own function:
function printr($data) {
echo "<pre>";
print_r($data);
echo "</pre>";
}
Apparantly, in 2018, people are still coming back to this question. The above would not be my current answer. I'd say: teach your editor to do it for you. I have a whole bunch of debug shortcuts, but my most used is vardd which expands to: var_dump(__FILE__ . ':' . __LINE__, $VAR$);die();
You can configure this in PHPStorm as a live template.
You can set the second parameter of print_r to true to get the output returned rather than directly printed:
$output = print_r($myarray, true);
You can use this to fit everything into one echo (don’t forget htmlspecialchars if you want to print it into HTML):
echo "<pre>", htmlspecialchars(print_r($myarray, true)), "</pre>";
If you then put this into a custom function, it is just as easy as using print_r:
function printr($a) {
echo "<pre>", htmlspecialchars(print_r($a, true)), "</pre>";
}
Probably not helpful, but if the array is the only thing that you'll be displaying, you could always set
header('Content-type: text/plain');
echo '<pre>' . print_r( $myarray, true ) . '</pre>';
From the PHP.net print_r() docs:
When [the second] parameter is set to TRUE, print_r() will return the information rather than print it.
teach your editor to do it-
after writing "pr_" tab i get exactly
print("<pre>");
print_r($);
print("</pre>");
with the cursor just after the $
i did it on textmate by adding this snippet:
print("<pre>");
print_r(\$${1:});
print("</pre>");
If you use VS CODE, you can use :
Ctrl + Shift + P -> Configure User Snippets -> PHP -> Enter
After that you can input code to file php.json :
"Show variable user want to see": {
"prefix": "pre_",
"body": [
"echo '<pre>';",
"print_r($variable);",
"echo '</pre>';"
],
"description": "Show variable user want to see"
}
After that you save file php.json, then you return to the first file with any extension .php and input pre_ -> Enter
Done, I hope it helps.
If you are using XDebug simply use
var_dump($variable);
This will dump the variable like print_r does - but nicely formatted and in a <pre>.
(If you don't use XDebug then var_dump will be as badly formated as print_r without <pre>.)
echo "<pre/>"; print_r($array);
Both old and accepted, however, I'll just leave this here:
function dump(){
echo (php_sapi_name() !== 'cli') ? '<pre>' : '';
foreach(func_get_args() as $arg){
echo preg_replace('#\n{2,}#', "\n", print_r($arg, true));
}
echo (php_sapi_name() !== 'cli') ? '</pre>' : '';
}
Takes an arbitrary number of arguments, and wraps each in <pre> for CGI requests. In CLI requests it skips the <pre> tag generation for clean output.
dump(array('foo'), array('bar', 'zip'));
/*
CGI request CLI request
<pre> Array
Array (
( [0] => foo
[0] => foo )
) Array
</pre> (
<pre> [0] => bar
Array [1] => zip
( )
[0] => bar
[0] => zip
)
</pre>
I just add function pr() to the global scope of my project.
For example, you can define the following function to global.inc (if you have) which will be included into your index.php of your site. Or you can directly define this function at the top of index.php of root directory.
function pr($obj)
{
echo "<pre>";
print_r ($obj);
echo "</pre>";
}
Just write
print_r($myarray); //it will display you content of an array $myarray
exit(); //it will not execute further codes after displaying your array
Maybe you can build a function / static class Method that does exactly that. I use Kohana which has a nice function called:
Kohana::Debug
That will do what you want. That's reduces it to only one line. A simple function will look like
function debug($input) {
echo "<pre>";
print_r($input);
echo "</pre>";
}
function printr($data)
{
echo "<pre>";
print_r($data);
echo "</pre>";
}
And call your function on the page you need, don't forget to include the file where you put your function in for example: functions.php
include('functions.php');
printr($data);
I would go for closing the php tag and then output the <pre></pre> as html, so PHP doesn't have to process it before echoing it:
?>
<pre><?=print_r($arr,1)?></pre>
<?php
That should also be faster (not notable for this short piece) in general. Using can be used as shortcode for PHP code.
<?php
$people = array(
"maurice"=> array("name"=>"Andrew",
"age"=>40,
"gender"=>"male"),
"muteti" => array("name"=>"Francisca",
"age"=>30,
"gender"=>"Female")
);
'<pre>'.
print_r($people).
'</pre>';
/*foreach ($people as $key => $value) {
echo "<h2><strong>$key</strong></h2><br>";
foreach ($value as $values) {
echo $values."<br>";;
}
}*/
//echo $people['maurice']['name'];
?>
I generally like to create my own function as has been stated above. However I like to add a few things to it so that if I accidentally leave in debugging code I can quickly find it in the code base. Maybe this will help someone else out.
function _pr($d) {
echo "<div style='border: 1px solid#ccc; padding: 10px;'>";
echo '<strong>' . debug_backtrace()[0]['file'] . ' ' . debug_backtrace()[0]['line'] . '</strong>';
echo "</div>";
echo '<pre>';
if(is_array($d)) {
print_r($d);
} else if(is_object($d)) {
var_dump($d);
}
echo '</pre>';
}
You can create Shortcut key in Sublime Text Editor using Preferences -> Key Bindings
Now add below code on right-side of Key Bindings within square bracket []
{
"keys": ["ctrl+shift+c"],
"command": "insert_snippet",
"args": { "contents": "echo \"<pre>\";\nprint_r(${0:\\$variable_to_debug});\necho \"</pre>\";\ndie();\n" }
}
Enjoy your ctrl+shift+c shortcut as a Pretty Print of PHP.

So i am having trouble getting an array from one PHP file to another.
In my first file (file1.php) i got following code:
print_r($order->delivery);
It will get visible when using echo of course, and it outputs the right things. It gives me an array with order information. Now i got another PHP file I need to use this information in.
What i tried so far is including file1.php to file2.php and then echo the array... But the result is empty.
require_once('path/file1.php');
echo print_r($order->delivery);
And i tried echo my array directly in file1.php adding a div like this
echo "<div id='test'>" . print_r($order->delivery, true) . "</div>";
And then getting the inner HTMl of the div with DOM
$dom = new DOMDocument();
$dom->loadHTML("mypageurl");
$xpath = new DOMXPath($dom);
$divContent = $xpath->query('//div[id="test"]');
if($divContent->length > 0) {
$node = $divContent->item(0);
echo "{$node->nodeName} - {$node->nodeValue}";
}
else {
// empty result set
}
Well... none of it works. Any suggestions?
You have to set a variable or something, not echoing it.
file1.php:
$delivery = $order->delivery;
file2.php
include('path/file1.php');
echo "<div id='test'>" . (isset($delivery['firstname']) ? $delivery['firstname'] : '') . "</div>";
Or you use the $object directly if it is set in file1.php
file2.php
include('path/file1.php');
echo "<div id='test'>" . (isset($order->delivery['firstname']) ? $order->delivery['firstname'] : '') . "</div>";
You can do this by using $_SESSION or $_COOKIE, See here for more detail; PHP Pass variable to next page
Be careful at the variable scope. See this link: http://php.net/manual/en/language.variables.scope.php
And try this code please:
require_once('path/file1.php');
global $order;
print_r($order->delivery);
Defining $order as global should fix your issue.
You could return an array in a file and use it in another like this:
<?php
/* File1.php */
return array(
0,1,2,3
);
-
<?php
/* File2.php */
var_dump(require_once('File1.php'));
I wanna replace braces with <?php ?> in a file with php extension.
I have a class as a library and in this class I have three function like these:
function replace_left_delimeter($buffer)
{
return($this->replace_right_delimeter(str_replace("{", "<?php echo $", $buffer)));
}
function replace_right_delimeter($buffer)
{
return(str_replace("}", "; ?> ", $buffer));
}
function parser($view,$data)
{
ob_start(array($this,"replace_left_delimeter"));
include APP_DIR.DS.'view'.DS.$view.'.php';
ob_end_flush();
}
and I have a view file with php extension like this:
{tmp} tmpstr
in output I save just tmpstr and in source code in browser I get
<?php echo $tmp; ?>
tmpstr
In include file <? shown as <!--? and be comment. Why?
What you're trying to do here won't work. The replacements carried out by the output buffering callback occur after PHP code has already been parsed and executed. Introducing new PHP code tags at this stage won't cause them to be executed.
You will need to instead preprocess the PHP source file before evaluating it, e.g.
$tp = file_get_contents(APP_DIR.DS.'view'.DS.$view.'.php');
$tp = str_replace("{", "<?php echo \$", $tp);
$tp = str_replace("}", "; ?>", $tp);
eval($tp);
However, I'd strongly recommend using an existing template engine; this approach will be inefficient and limited. You might want to give Twig a shot, for instance.
do this:
function parser($view,$data)
{
$data=array("data"=>$data);
$template=file_get_contents(APP_DIR.DS.'view'.DS.$view.'.php');
$replace = array();
foreach ($data as $key => $value) {
#if $data is array...
$replace = array_merge(
$replace,array("{".$key."}"=>$value)
);
}
$template=strtr($template,$replace);
echo $template;
}
and ignore other two functions.
How does this work:
process.php:
<?php
$contents = file_get_contents('php://stdin');
$contents = preg_replace('/\{([a-zA-Z_][a-zA-Z_0-9]*)\}/', '<?php echo $\1; ?>', $contents);
echo $contents;
bash script:
process.php < my_file.php
Note that the above works by doing a one-off search and replace. You can easily modify the script if you want to do this on the fly.
Note also, that modifying PHP code from within PHP code is a bad idea. Self-modifying code can lead to hard-to-find bugs, and is often associated with malicious software. If you explain what you are trying to achieve - your purpose - you might get a better response.
I'm currently stuck on what I thought would be an easy solution... I'm working with PHPFileNavigator, and the only thing I'm stuck on is how I can echo the Title that is returned to an array on a separate file. Every time a file is created/edited for an uploaded file, it generates the following file below when a title is added to the file.
Update
Generally all I'm wanting to do is return the one Array value from my destination file which in this case would be from the 'titulo' key, and then print it back to my source file.
Destination File
<?php
defined('OK') or die();
return array(
'titulo' => 'Annual 2011 Report',
'usuario' => 'admin'
);
?>
Source File
<?php
$filepath="where_my_destination_file_sits";
define('OK', True); $c = include_once($filepath); print_r($c);
?>
Current Result
Array ( [titulo] => Annual 2011 Report [usuario] => admin )
Proposed Result
Annual 2011 Report
All I'm wanting to find out is how can I echo this array into a variable on another PHP page? Thanks in advance.
Assuming your file is saved at $filepath
<?php
define('OK', True);
$c = include_once($filepath);
print_r($c);
If you know the file name and file path, you can easily capture the returned construct of the php file, to a file.
Here is an example:
$filepath = 'path/to/phpfile.php';
$array = include($filepath); //This will capture the array
var_dump($array);
Another example of include and return working together: [Source: php.net]
return.php
<?php
$var = 'PHP';
return $var;
?>
noreturn.php
<?php
$var = 'PHP';
?>
testreturns.php
<?php
$foo = include 'return.php';
echo $foo; // prints 'PHP'
$bar = include 'noreturn.php';
echo $bar; // prints 1
?>
Update
To only print a item from the array, you can use the indices. In your case:
<?php
$filepath="where_my_destination_file_sits";
define('OK', True); $c = include_once($filepath); print_r($c);
echo $c['titulo']; // print only the title
?>
First we have a file(you want initiate array in it ) first.php
(you can also act profissionaler and play with parameters,with any parameter function pass different type or different array)
function first_passing() {
$yourArray=array('everything you want it's be');
return $yourArray;
}
And in second.php
require 'yourpath/first.php' (or include or include_once or require_once )
//and here just call function
$myArray=first_passing();
//do anything want with $myArray
To print/echo an array in PHP you have to use print_r($array_variable) and not echo $array
I use this :
<?php
foreach($_SERVER as $key => $value){
echo "<b>$key:</b> $value<br>\n";
}
?>
Which outputs in browser. Is there anyway to redirect output to file and hide it from the browser page ?
I would suggest something like:
<?php
foreach($_SERVER as $key => $value)
{
file_put_contents('the_file.txt', "<b>$key:</b> $value<br>\n", FILE_APPEND);
}
?>
Make sure that the_file.txt has write permissions.
Instead of echoing build an output to put in your file:
<?php
$in='';
foreach($_SERVER as $key => $value){
$in .= $key.' - '.$value.PHP_EOL;
}
//save it
file_put_contents('_SERVER.txt', $in);
?>
Also, Your not going to want to add any html tags.
To write a file you would want to use file_put_contents(). To generate a (human) readable representation of the contents of $_SERVER you should look into print_r() or var_export().
file_put_contents("/tmp/exported-server.txt", print_r($_SERVER, true));
using $s = print_r($_SERVER), $s = var_export($_SERVER) or even ob_start(); var_dump($_SERVER); $s = ob_get_clean(); makes sure you get a proper visualization of any value type. Your approach only works well for strings and numbers, but fails for arrays, objects, …
file or file_get_contents do not read this sample file properly
<?php
?>
This is the test program
$flines=file('../include/test.php');
echo '<pre>';
print_r($flines);
echo '</pre>';
for($i=0;$i<count($flines);$i++) {
echo("$i:".$flines[$i]."\n<br>");
}
echo "File Get Contents";
echo(file_get_contents('../include/test.php'));
This is the output
Array
(
[0] => ?>
)
0:1:?>
File Get Contents
Basically it skips the php declaration for some reason... and the file is empty
addition
every works fine when removing the opening < of course
You didn't trick php, php was right all along; you tricked yourself....
$flines=file('./x.php');
echo '<pre>';
print_r(array_map('htmlentities',$flines));
echo '</pre>';
for($i=0;$i<count($flines);$i++) {
echo("$i:".htmlentities($flines[$i])."\n<br>");
}
echo "File Get Contents";
echo(htmlentities(file_get_contents('./x.php')));
Think about what a web browser does when it encounters < rather than <
