php 1234 converted to array

In PHP, we can use some built-in functions to convert strings into arrays. In this article, we will explain how to convert a string like "php 1234" into an array.

Method 1: Use the explode() function

Theexplode() function can split a string into multiple substrings, and then store these substrings in an array. We can use spaces to split the string into two substrings, "php" and "1234", and then store them in an array. The specific code is as follows:

$str = "php 1234";
$arr = explode(" ", $str);
print_r($arr);

The output result of this code is:

Array
(
    [0] => php
    [1] => 1234
)

Method 2: Use the preg_split() function

The preg_split() function is similar to the explode() function , you can split the string into substrings and store them in an array. However, it can use regular expressions as delimiters, making it more flexible. We can use a regular expression "/\s /" to split the string with one or more spaces as delimiters. The specific code is as follows:

$str = "php 1234";
$arr = preg_split("/\s+/", $str);
print_r($arr);

The output result of this code is the same as the output result of the code of method 1.

Method 3: Use the str_split() function

The str_split() function can split a string into a character array. However, in this case, we need to split the string into two substrings, not into an array of characters. Therefore, we need to process the result after splitting to convert it into the array we need. The specific code is as follows:

$str = "php 1234";
$arr = str_split($str, 4);
$arr[0] = trim($arr[0]);
print_r($arr);

The output result of this code is the same as the output result of the code of method 1.

Summary

In PHP, we can use the above method to convert the string "php 1234" into an array. Among them, using the explode() function is the simplest method, while using the preg_split() function is more flexible when processing complex strings, and the str_split() function is more suitable for processing some strings with fixed formats. Depending on the situation, we can choose different methods to convert strings into arrays.
