PHP SOAP has been made available beginning from PHP version 5.0.1 . Users who are still using PHP4 need to use NuSOAP.Native PHP codes are better in terms of performance & relatively bug free. Hence it is suggested to use PHP SOAP if it is available.On the other hand, NuSOAP doesn't have much documentation on their official website as well.Salient features of NuSOAPIt comes with a few predefined methods whereas they need to be written on one's own in case of Soap.The performance metric for SOAP is server response time.Handling UTF-8 is much easier in Nusoap.Nusoap offers certain functions that ...

The __DIR__ can be used to obtain the current code working directory. It has been introduced in PHP beginning from version 5.3. It is similar to using dirname(__FILE__). Usually, it is used to include other files that is present in an included file.Consider the following directory structure −A directory called "master", that has two files named 'worker_1', and 'worker_2'. The master directory itself is a subfolder of the main project directory.The project directory also contains an index.php file.Consider having two files in a directory called inc, which is a subfolder of our project's directory, where the index.php file lies −project_directory ...

JShell is the REPL tool that has introduced in Java 9. We can use this tool to execute simple snippets in the command-line prompt.When we enter an arithmetic expression, variable, etc in JShell, then it displays the result without details of the type of variable created. It is possible in JShell to display more information about the execution of an entered command, use verbose mode. We need to obtain more information on the commands executed by using the command: "/set feedback verbose" (the command can be preceded by "/").In the below snippet, the verbose mode is on, and it can able to ...

Below is a demonstration of the function.Example Live DemoOutputThis will produce the following output −\s\a\m\p\l\e\[ \]

The reason behind in_array returning True could be the string-to-number conversion. When a string is passed to the function, it returns 0, which is the value that needs to be searched for.PHP uses loose juggling, i.e. using == instead of === when elements are compared. Hence, their values are compared and not the types.Another reason is type juggling, which means a variable type is dealt with in the context of the code.For example- when a float value is assigned to a variable, it becomes a floating-point value. It behaves in a way when a string is casted to an integerTo ... Read More

The code inside the 'Model' and the 'Controller' needs to be changed to include code that is shown below −Inside the 'Controller'$header = $this->model_name->call_head(); foreach($header as $item) {    $name = $item['name'];    $array['name'] = $name;    $array['data'] = $item['data'];    $child_val = $this->model_name->call_child($name);    foreach($child_val as $value) {       $array['child'] = array(          'child_name' => $value['child_name'],          'child_data' => $value['child_data']       );    } }Inside the 'model'public function call_head() {    $query = "CALL PROCEDURE_HEAD()";    $result = $this->db->query($query)->result_array();    $query->next_result();    $query->free_result();    return $result; } public function ...

The json_decode function can be used as shown below −json_decode($json_string_that_needs_to_be_converted, true);The below lines of code can be used to convert JSONL to array format −$json_string = '["m@gmail.com", "p@gmail.com", "q@gmail.com"]'; $array_of_data=json_decode($json_string);An alternate is to use the below code, wherein the way json_string has been defined changes −Example$json_string = "[\"m@gmail.com\", \"p@gmail.com\", \"q@gmail.com\"]"; $array_of_data=json_decode($json_string);OutputThis will produce the following output −Array("m@gmail.com", "p@gmail.com", "q@gmail.com")Read More

The below code can be used to convert hex value into HSL value −function hex_To_Hsl($hex) {    $hex_val = array($hex_val[0].$hex_val[1], $hex_val[2].$hex_val[3], $hex_val[4].$hex_val[5]);    $rgb_val = array_map(function($part) {       return hexdec($part) / 255;    }, $hex_val);    $max_val = max($rgb_val);    $min_val = min($rgb_val);    $l = ($max_val + $min_val) / 2;    if ($max_val == $min_val) {       $h = $s = 0;    } else {       $diff = $max_val - $min_val;       $s = $l > 0.5 ? $diff / (2 - $max_val - $min_val) : $diff / ($max_val + ...
