Get the name of a variable passed into a PHP function? - php

I just threw this together to help in debugging some PHP scripts. As you can see, it is sloppy but I am going to improve it some more.
My debug function has 2 variables passed in, a variable name and a variable value.
Is it possible to just pass in the variable and somehow get the name of the variable without manually doing it like I have it set now?
The Function
<?php
function debug($varname, $var)
{
echo '<br>' . $varname;
// $var is a STRING
if (is_string($var)) {
echo ' (string) = ' . $var . '<br>';
// $var is an ARRAY
} elseif (is_array($var)) {
echo ' (array) = <pre>';
print_r($var);
echo '</pre><br>';
// $var is an INT
} elseif (is_int($var)) {
echo ' (int) = ' . $var . '<br>';
// $var is an OBJECT
} elseif (is_object($var)) {
echo ' (object) = <pre>';
var_dump($var);
echo '</pre><br>';
}
}
The Test
$testString = 'just a test!';
$testArray = array(
'key1' => 'value1',
'key2' => 'value2',
'key3' => 'value3'
);
$testInt = 1234567890;
$testObject = new stdClass;
$testObject->someVar1 = 'testing123';
$testObject->someVar2 = '321gnitset';
debug('$testString', $testString);
debug('$testArray', $testArray);
debug('$testInt', $testInt);
debug('$testObject', $testObject);
?>
The Result...
$testString (string) = just a test!
$testArray (array) =
Array
(
[key1] => value1
[key2] => value2
[key3] => value3
)
$testInt (int) = 1234567890
$testObject (object) =
object(stdClass)#1 (2) {
["someVar1"]=>
string(10) "testing123"
["someVar2"]=>
string(10) "321gnitset"
}

If you want to know the name, why not just pass a string constant of the name of the variable, and use global array to access it (for procedural programs)
function foo($var) {
echo $var; //name of the variable
echo $GLOBALS[$$var]; //value of the variale
}
$bar = 'a string';
foo('bar');

Check out this php function func_get_arg()
Actually... it looks like you can't really do it... check this other question How to get a variable name as a string in PHP?

debug_print_backtrace() is your friend! Add it to your debug() function.
If you still want only the calling function name you can use debug_backtrace() and search in the returned array for the name of the previous function, identified as "function" in the associative array result!

I put together these functions for my own debugging just copy and save it in a separate file, include it and use the function d() to call the fancy debug print. it suppose to color code the results based on the type of variable passed.
if(!defined('m_debug')) {define('m_debug', 1);}
function d($var) {
if (m_debug) {
$bt = debug_backtrace();
$src = file($bt[0]["file"]);
$line = $src[ $bt[0]['line'] - 1 ];
//striping the inspect() from the sting
$strip = explode('d(', $line);
$matches = preg_match('#\(#', $strip[0]);
$strip = explode(')', $strip[1]);
for ($i=0;$i<count($matches-1);$i++) {
array_pop($strip);
}
$label = implode(')', $strip);
d_format($var, $label);
}
}
function l() {
global $super_dump_log;
if (func_num_args() > 0) {
$array = func_get_args();
array_merge($super_dump_log, $array);
} else {
foreach($super_dump_log as $log){
//
}
}
}
function d_format($var, $label) {
$colorVar = 'Blue';
$type = get_type($var);
$colorType = get_type_color($type);
echo "<div class='m_inspect' style='background-color:#FFF; overflow:visible;'><pre><span style='color:$colorVar'>";
echo $label;
echo "</span> = <span class='subDump' style='color:$colorType'>";
if ($type == 'string') {
print_r(htmlspecialchars($var));
} else {
print_r($var);
}
echo "</span></pre></div>";
}
function get_type($var) {
if (is_bool($var)) {
$type = 'bool';
} elseif (is_string($var)) {
$type = 'string';
} elseif (is_array($var)) {
$type = 'array';
} elseif (is_object($var)) {
$type = 'object';
} elseif (is_numeric($var)) {
$type = 'numeric';
} else {
$type = 'unknown';
}
return $type;
}
function get_type_color($type) {
if ('bool' == $type) {
$colorType = 'Green';
} elseif ('string' == $type) {
$colorType = 'DimGrey';
} elseif ('array' == $type) {
$colorType = 'DarkOrchid';
} elseif ('object' == $type) {
$colorType = 'BlueViolet';
} elseif ('numeric' == $type) {
$colorType = 'Red';
} else {
$colorType = 'Tomato';
}
return $colorType;
}

You can do this from the other end. Pass the variable name in a string variable and then call it with $$ to pass the actual variable. I made my_var_dump function:
function my_var_dump($varName, $var, $line = false, $func = false)
{
if ($func) $func = ' in function ' . $func;
if ($line) $line = ' at line ' . $line;
echo '<pre>DEBUG $' . $varName . $line . $func . PHP_EOL;
var_dump($var);
echo '</pre>' . PHP_EOL;
}
Call this function like this:
my_var_dump($varName = "some_var_name", $$varName, __LINE__, __FUNCTION__);

SOLUTION :
$argv — Array of arguments passed to script
EXAMPLE :
<?php
var_dump($argv);
?>

PHP recursive multidimensional loop

$printArr = recursive($newArray); //calls recursive function
$data = [];
var_dump($data);
var_dump($printArr);
function recursive($array, $level = 0)
{
$searchingValue = 'tableName';
foreach($array as $key => $value)
{
//If $value is an array.
if(is_array($value))
{
recursive($value, $level + 1);
}
else
{
//It is not an array, so print it out.
if($key == $searchingValue)
{
echo "[".$key . "] => " . $value, '<br>';
$data[] = $value;
}
}
}
}
So I have this function and I am trying to save $value value into $data[] array. But it always returns it empty and I don't know why I can't get $value saved outside the function.
If i echo $value I get what i need but like I've mentioned the variables doesn't get saved in this case - table names.
You need to pass the $data to your recursive function. Also you need to return the $data.
Try this code :
function recursive($array, $level = 0, $data =[])
{
$searchingValue = 'tableName';
foreach($array as $key => $value)
{
//If $value is an array.
if(is_array($value))
{
recursive($value, $level + 1 , $data);
}
else
{
//It is not an array, so print it out.
if($key == $searchingValue)
{
echo "[".$key . "] => " . $value, '<br>';
$data[] = $value;
}
}
}
return $data;
}
You can't access variable $data, which is outside the function, from the function. You need to pass it by reference or return it. Small example
<?php
$a = 1;
// Your case
function b() {
$a = 4;
return true;
}
// Passing by reference
function c(&$d) {
$d = 5;
return true;
}
// Using return
function d($d) {
$d = 6;
return $d;
}
b();
var_dump($a);
c($a);
var_dump($a);
$a = d($a);
var_dump($a);

My cookie class keeps returning null when getting the cookie

I set a test cookie for example app('cookie')->set('test', 'hello', 0);
sure enough it created the cookie like expected. So the cookie reads string(hello)
When I try to echo it, it echos the default value instead of the actual variable, so app('cookie')->get('test', 'test'); returns test
The get function should check if the cookie exists with isset($_COOKIE[$cookieName]) and then it should trim the extra ) with rtrim($_COOKIE[$cookieName], ')') then it should grab the first character in the string with mb_substr($_COOKIE[$cookieName], 0, 1) the 0 starts at the beginning and the 1 grabs only the first character.
After it compares it with the default (a, b, i, f, s) for example if it starts with an s its a string by default, if it was i it was sent as an int by default, etc. etc.
If they all come up as false it checks to see if it was sent as null if so it return null else it returns the default value passed.
The equals function is the same as $var1 == $var2 it is timing attack safe.
so it keeps returning the default value which is null, any help would be helpful thanks in advance.
Lol i feel real stupid i put 0 as the third argument thinking it will tell the cookie to expire when the browser session closes, but it did (time() + 0) which does not equal 0. so as it was setting the cookie it expired upon creation. So i did time() - (time() * 2). i achieved the goal i wanted.

How to merge two arrays and concat the values with PHP

I'm looking for an easy solution to create a little function to merge two arrays with value concat (I'm using it to create html tag attribute):
$default["class"] = "red";
$new["class"] = "green";
$new["style"] = "display:block"
The result:
$res["class"] = "red green";
$res["style"] = "display: block";
and one more option:
if the $new is not an array, just concat with the $default["class"] (if this exist), and the other side: if the $default is a simple string, convert to array: $default["class"] = $default;
I created a function but would like to use an easier, shorter way for that:
function attrMerge( $default, $new="" ){
$res = array();
if(!is_array($default)) {
$res["class"] = $default;
}
else {
$res = $default;
}
if( $new !== "" ){
if(!is_array($new)) {
if(isset($res["class"])){
$res["class"].= " ".$new;
}
}
else {
foreach($new as $key=>$value) {
if( isset($res[$key]) ) {
$res[$key].= " ".$value;
}
else {
$res[$key] = $value;
}
}
}
}
return $res;
}
$a = attrMerge("red", array("class"=>"green", "style"=>"display: block;"));
I think this is the function that you need. I have initialised the css classes and styles as empty and in depends what you pass into the function then you get the relevant array
/**
* This function returns an array of classes and styles
*
* #param $default
* #param $new
* #return array
*/
function attrMerge($default=null, $new=nul)
{
$result = array();
$result['class'] = "";
$result['style'] = "";
// add default class if exists
if (!empty($default) && is_string($default)) {
// $default is string
$result['class'] = $default;
}
if (!empty($default)
&& is_array($default)
) {
if (array_key_exists('class', $default)
&& !empty($default['class'])
) {
// $default['class'] exists and it's not empty
$result['class'] = $default['class'];
}
if (array_key_exists('style', $default)
&& !empty($default['style'])
) {
// $default['style'] exists and it's not empty
$result['style'] = $default['style'];
}
}
// add additional classes OR styles
if (!empty($new)) {
if(!is_array($new)) {
$result['class'] = empty($result['class'])
? $new
: $result['class'] . " " . $new;
} else {
foreach ($new as $key => $value) {
if (isset($result[$key])) {
$result[$key] = empty($result[$key])
? $value
: $result[$key] . " " . $value;
} else {
$result[$key] = $value;
}
}
}
}
return $result;
}
A way I believe suits your need, hopefully it's as adaptable and effecient as you were expecting.
$array1 = array(
'class' => 'class1',
'style' => 'display: none;'
);
$array2 = array(
'class' => 'class2'
);
$arrayFinal = arrayMerge($array1, $array2);
var_dump($arrayFinal);
function arrayMerge($arr1, $arr2 = ''){
// Array of attributes to be concatenated //
$attrs = array('class');
if(is_array($arr2)){
foreach($attrs as $attr){
if(isset($arr1[$attr]) && isset($arr2[$attr])){
// Not using .= to allow for smart trim (meaning empty check etc isn't needed //
$arr1[$attr] = trim($arr1[$attr] . ' ' . $arr2[$attr]);
}
}
}else{
$arr1['class'] = trim($arr1['class'] . ' ' . $arr2);
}
return $arr1;
}
$def = ['class' => 'red'];
$new = ['class' => 'green', 'style' => 'style'];
function to_array($in) {
return is_array($in) ? $in : ['class' => $in];
}
$def = to_array($def);
$new = to_array($new);
$res = $def;
array_walk($new, function ($val, $key) use (&$res) {
$res[$key] = trim(#$res[$key] . ' ' . $val);
});
var_dump($res);

Using PHP write an anagram function?

Using PHP write an anagram function? It should be handling different phrases and return boolean result.
Usage:
$pharse1 = 'ball';
$pharse2 = 'lbal';
if(is_anagram($pharse1,$pharse2)){
echo $pharse1 .' & '. $pharse2 . ' are anagram';
}else{
echo $pharse1 .' & '. $pharse2 . ' not anagram';
}
There's simpler way
function is_anagram($a, $b) {
return(count_chars($a, 1) == count_chars($b, 1));
}
example:
$a = 'argentino';
$b = 'ignorante';
echo is_anagram($a,$b); // output: 1
$a = 'batman';
$b = 'barman';
echo is_anagram($a,$b); // output (empty):
function is_anagram($pharse1,$pharse2){
$status = false;
if($pharse1 && $pharse2){
$pharse1=strtolower(str_replace(" ","", $pharse1));
$pharse2=strtolower(str_replace(" ","", $pharse2));
$pharse1 = str_split($pharse1);
$pharse2 = str_split($pharse2);
sort($pharse1);
sort($pharse2);
if($pharse1 === $pharse2){
$status = true;
}
}
return $status;
}
function check_anagram($str1, $str2) {
if (count_chars($str1, 1) == count_chars($str2, 1)) {
return "This '" . $str1 . "', '" . $str2 . "' are Anagram";
}
else {
return "This two strings are not anagram";
}
}
ECHO check_anagram('education', 'ducatione');
I don't see any answers which have addressed the fact that capital letters are different characters than lowercase to count_chars()
if (isAnagram('Polo','pool')) {
print "Is anagram";
} else {
print "This is not an anagram";
}
function isAnagram($string1, $string2)
{
// quick check, eliminate obvious mismatches quickly
if (strlen($string1) != strlen($string2)) {
return false;
}
// Handle uppercase to lowercase comparisons
$array1 = count_chars(strtolower($string1));
$array2 = count_chars(strtolower($string2));
// Check if
if (!empty(array_diff_assoc($array2, $array1))) {
return false;
}
if (!empty(array_diff_assoc($array1, $array2))) {
return false;
}
return true;
}
here is my variant :
public function is_anagram($wrd_1, $wrd_2)
{
$wrd_1 = str_split ( strtolower ( utf8_encode($wrd_1) ) );
$wrd_2 = str_split( strtolower ( utf8_encode($wrd_2) ) );
if ( count($wrd_1)!= count($wrd_2) ) return false;
if ( count( array_diff ( $wrd_1 ,$wrd_2) ) > 0 ) return false;
return true;
}
Heheh little large but work as well :)
public static function areStringsAnagrams($a, $b)
{
//throw new Exception('Waiting to be implemented.');
$a = str_split($a);
$test = array();
$compare = array();
foreach ($a as $key) {
if (!in_array($key, $test)) {
array_push($test, $key);
$compare[$key] = 1;
} else {
$compare[$key] += 1;
}
}
foreach ($compare as $key => $value) {
if ($value !== substr_count($b, $key)) {
return false;
}
}
return true;
}

PHP recursive variable replacement

I'm writing code to recursively replace predefined variables from inside a given string. The variables are prefixed with the character '%'. Input strings that start with '^' are to be evaluated.
For instance, assuming an array of variables such as:
$vars['a'] = 'This is a string';
$vars['b'] = '123';
$vars['d'] = '%c'; // Note that $vars['c'] has not been defined
$vars['e'] = '^5 + %d';
$vars['f'] = '^11 + %e + %b*2';
$vars['g'] = '^date(\'l\')';
$vars['h'] = 'Today is %g.';
$vars['input_digits'] = '*****';
$vars['code'] = '%input_digits';
The following code would result in:
a) $str = '^1 + %c';
$rc = _expand_variables($str, $vars);
// Result: $rc == 1
b) $str = '^%a != NULL';
$rc = _expand_variables($str, $vars);
// Result: $rc == 1
c) $str = '^3+%f + 3';
$rc = _expand_variables($str, $vars);
// Result: $rc == 262
d) $str = '%h';
$rc = _expand_variables($str, $vars);
// Result: $rc == 'Today is Monday'
e) $str = 'Your code is: %code';
$rc = _expand_variables($str, $vars);
// Result: $rc == 'Your code is: *****'
Any suggestions on how to do that? I've spent many days trying to do this, but only achieved partial success. Unfortunately, my last attempt managed to generate a 'segmentation fault'!!
Help would be much appreciated!
Note that there is no check against circular inclusion, which would simply lead to an infinite loop. (Example: $vars['s'] = '%s'; ..) So make sure your data is free of such constructs.
The commented code
// if(!is_numeric($expanded) || (substr($expanded.'',0,1)==='0'
// && strpos($expanded.'', '.')===false)) {
..
// }
can be used or skipped. If it is skipped, any replacement is quoted, if the string $str will be evaluated later on! But since PHP automatically converts strings to numbers (or should I say it tries to do so??) skipping the code should not lead to any problems.
Note that boolean values are not supported! (Also there is no automatic conversion done by PHP, that converts strings like 'true' or 'false' to the appropriate boolean values!)
<?
$vars['a'] = 'This is a string';
$vars['b'] = '123';

echo expand('%h',$vars);
echo '<br/>';
echo expand('Your code is: %code',$vars);
echo '<br/>';
echo expand('Some Info: %i',$vars);
?>
The above code assumes PHP 5.3 since it uses a closure.
Output:

Today is Tuesday.
Your code is: *****

For PHP < 5.3 the following adapted code can be used:
function expand2($str, $vars) {
$regex = '/\%(\w+)/';
$eval = substr($str, 0, 1) == '^';
$res = preg_replace_callback($regex, array(new Helper($vars, $eval),'callback'), $str);
if($eval) {
ob_start();
$expr = substr($res, 1);
if(eval('$res = ' . $expr . ';')===false) {
ob_end_clean();
die('Not a correct PHP-Expression: '.$expr);
}
ob_end_clean();
}
return $res;
}
class Helper {
var $vars;
var $eval;
function Helper($vars,$eval) {
$this->vars = $vars;
$this->eval = $eval;
}
function callback($matches) {
if(isset($this->vars[$matches[1]])) {
$expanded = expand($this->vars[$matches[1]], $this->vars);
if($this->eval) {
// Special handling since $str is going to be evaluated ..
if(!is_numeric($expanded) || (substr($expanded . '', 0, 1)==='0'

}
}
return $expanded;
} else {
// Variable does not exist in $vars array
if($this->eval) {
return 'null';
}
return $matches[0];
}
}
}
I now have written an evaluator for your code, which addresses the circular reference problem, too.
Use:
$expression = new Evaluator($vars);
$vars['a'] = 'This is a string';
// ...
$vars['circular'] = '%ralucric';
$vars['ralucric'] = '%circular';
echo $expression->evaluate('%circular');
I use a $this->stack to handle circular references. (No idea what a stack actually is, I simply named it so ^^)
class Evaluator {
private $vars;
private $stack = array();
private $inEval = false;

Edit 1: I tested the maximum recursion depth for this script using this:
$alphabet = 'abcdefghijklmnopqrstuvwxyzABCDEF'; // GHIJKLMNOPQRSTUVWXYZ
$length = strlen($alphabet);
$vars['a'] = 'Hallo World!';
for ($i = 1; $i < $length; ++$i) {
$vars[$alphabet[$i]] = '%' . $alphabet[$i-1];
}
var_dump($vars);
$expression = new Evaluator($vars);
echo $expression->evaluate('%' . $alphabet[$length - 1]);
If another character is added to $alphabet maximum recursion depth of 100 is reached. (But probably you can modify this setting somewhere?)
I actually just did this while implementing a MVC framework.
What I did was create a "find-tags" function that uses a regular expression to find all things that should be replaced using preg_match_all and then iterated through the list and called the function recursively with the str_replaced code.
VERY Simplified Code
function findTags($body)
{
$tagPattern = '/{%(?P<tag>\w+) *(?P<inputs>.*?)%}/'
preg_match_all($tagPattern,$body,$results,PREG_SET_ORDER);
foreach($results as $command)
{
$toReturn[] = array(0=>$command[0],'tag'=>$command['tag'],'inputs'=>$command['inputs']);
}
if(!isset($toReturn))
$toReturn = array();
return $toReturn;
}
function renderToView($body)
{
$arr = findTags($body);
if(count($arr) == 0)
return $body;
else
{
foreach($arr as $tag)
{
$body = str_replace($tag[0],$LOOKUPARRY[$tag['tag']],$body);
}
}
return renderToView($body);
}
