PHP Str_getcsv implements the method of parsing strings into arrays

The following small series for everyone to bring a PHP str_getcsv string parsing to the implementation of the array. Small series feel very good, now share to everyone, also for everyone to make a reference. Let's take a look at it with a little knitting.

PHP uses the explode method to parse string parsing into arrays based on delimiters.

For example: Use "," to parse a string into an array of delimiters

<?php$str = ' explode '; $arr = (', ', $str);p Rint_r ($arr);? >

Output:

Array (  [0] = 1  [1] = 2  [2] = 3)

But for some more complex strings, such as the CSV format, using explode does not produce the desired results, and using the regular is cumbersome.

For example:

<?PHP$STR = "China, Guangdong Province, Guangzhou, Tianhe District, ' 113.329884,23.154799 ', 1, ' 2016-01-01 12:00:00 ', ' 1,2,3,4,5,6 '"; $arr = Explode (', ', $ STR);p Rint_r ($arr);? >

Output:

Array (  [0] = China  [1] = Guangdong province  [2] = Guangzhou  [3] = Tianhe District  [4] = = 113.329884  [5] = 23.1 54799 '  [6] = 1  [7] = ' 2016-01-01 12:00:00 '  [8] = ' 1  [9] = 2  [Ten] = 3  [11] = > 4  [[] = 5  [] + 6 ')

In fact, the desired result is:

Array (  [0] = China  [1] = Guangdong province  [2] = Guangzhou  [3] = Tianhe District  [4] = 113.329884,23.154799< C21/>[5] = 1  [6] = 2016-01-01 12:00:00  [7] = 1,2,3,4,5,6)

PHP provides the str_getcsv method for processing strings as a CSV format, which makes it easy to parse the array.

str_getcsv parsing a CSV string as an array

Array str_getcsv (String $input [, String $delimiter = "," [, String $enclosure = ' "' [, string $escape =" \ \ "]])

Parameters:

input string to parse

delimiter set field qualifiers (single character only)

Enclosure Set field wrap character (single character only)

Escape Sets the escape character (only a single character), and the default is a backslash (\)

Instance:

<?PHP$STR = "China, Guangdong Province, Guangzhou, Tianhe District, ' 113.329884,23.154799 ', 1, ' 2016-01-01 12:00:00 ', ' 1,2,3,4,5,6 '"; $arr = Str_getcsv ($str , ', ', ' ' ');p rint_r ($arr);? >

Output:

Array (  [0] = China  [1] = Guangdong province  [2] = Guangzhou  [3] = Tianhe District  [4] = 113.329884,23.154799  [5] = 1  [6] = 2016-01-01 12:00:00  [7] = 1,2,3,4,5,6)
