The parse_str() function parses the query string into variables.

Grammar

parse_str(string,array)

Parameter Description
string required. Specifies the string to parse.
array optional. Specifies the name of the array to store the variable. This parameter instructs the variable to be stored in an array.

Tips and Notes

Note: If the array parameter is not set, the variables set by this function will overwrite variables already set by the same name.

Note: The magic_quotes_gpc setting in php.ini affects the output of this function. If enabled, variables are transformed by addslashes() before being parsed by parse_str() .

Example

Example 1

print_r($myArray);
?>

Output:

Copy code The code is as follows:

Array
(
[id] => 23
[name] => John Adams
)

php splits the specified characters in the string into arrays

$str="1|2|3|4|5|";
$var=explode("|",$str);
print_r($var) ;
?>
$var=explode("|",$str);
Split $str according to |
php and other methods split the specified characters in the string into arrays
str_split(string, length) parameter description
string required. Specifies the string to be split.
length optional. Specifies the length of each array element. The default is 1.

What is the function for splitting strings in PHP?

This function is substr example: echo substr('abcdef123', 1, 3); // Output bcd

If you are splitting the string into single characters, use split('abcde' ), this returns an array.
If your string has fixed delimiters, you can use explode('|','a|b|cd|e'). This returns an array.
