如何在php中将字符串转换为数组

Question

如何在PHP中转换数组中的字符串即

 $str="this is string";

应该是这样的

 arr[0]=this
      arr[1]=is
      arr[2]=string 

该

str_split($str, 3);

将字符串拆分为3个字符的单词,但我想在数组中的空格后转换字符串.

$array = explode(' ', $string);

随着php的爆炸功能

$array=explode(" ",$str);

<?php

$str = "Hello Friend";

$arr1 = str_split($str);
$arr2 = str_split($str, 3);

print_r($arr1);
print_r($arr2);

?>

像这样尝试 json_decode

<?php

   $var = '["SupplierInvoiceReconciliation"]';
   $var = json_decode($var, TRUE);
   print_r($var);
?>

Answer 5

看一下爆炸功能。

<?php
// Example 1
$pizza  = "piece1 piece2 piece3 piece4 piece5 piece6";
$pieces = explode(" ", $pizza);
echo $pieces[0]; // piece1
echo $pieces[1]; // piece2
?>
