array explode (string $separator, string $string [, int $limit])
This function has 3 parameters. The first parameter $separator sets a splitting character (string). The second parameter $string specifies the string to be operated on. The $limit parameter is optional and specifies the maximum number of substrings to split the string into.
This function returns an array consisting of divided substrings.
Look at the following example to analyze multiple lines of text data separated by commas.
Example 1, split string.
$this_year = 2013;
$text = Zhu Wushuang, F, 1982, Guangdong, general staff
Li Sanbing, M, 1981, Hebei, general staff
Zhao Puxiu, F, 1980, South Korea, project manager
EOT;
$lines = explode("n", $text); //Separate multiple lines of data
foreach ($lines as $userinfo) {
$info = explode(",", $ userinfo, 3); //Only split the first three data
$name = $info[0];
$sex = ($info[1] == "F")? "Female" : "Male ";
$age = $this_year - $info[2];
echo "Name: $name $sex . Age: $age
";
}
/* The output result is:
Name: Zhu Wushuang Female Age: 31
Name: Li Sanbing Male Age: 32
Name: Zhao Puxiu Female Age: 33
*/
?>
The above code first splits the text by lines, then splits each line of string by ",", and takes the first three data for processing and analysis, and then organizes and outputs them.
In addition, I will introduce to you another built-in function implode() in PHP, which is used to connect arrays into strings.
Corresponding to the split string function is the implode() function, its alias function is called join(), and the function prototypes are as follows.
string implode(string $glue, array $pieces)
string join(string $glue, array $pieces)
The implode() or join() function can connect the elements in the array $pieces with the specified character $glue.
The following is a simple example for your reference.
Example 2:
$fruits = array( 'apple', 'banana', 'pear');
$str = implode(", ", $fruits);
echo $str;
?>

You should care about DependencyInjection(DI) because it makes your code clearer and easier to maintain. 1) DI makes it more modular by decoupling classes, 2) improves the convenience of testing and code flexibility, 3) Use DI containers to manage complex dependencies, but pay attention to performance impact and circular dependencies, 4) The best practice is to rely on abstract interfaces to achieve loose coupling.

Select DependencyInjection (DI) for large applications, ServiceLocator is suitable for small projects or prototypes. 1) DI improves the testability and modularity of the code through constructor injection. 2) ServiceLocator obtains services through center registration, which is convenient but may lead to an increase in code coupling.
