Discuss the specific ways of splitting strings in PHP_PHP Tutorial

We are using Result: Array ( [0] => 1 [1] => 2 [2] => ; 3 [3] => 4 )

Definition and usage
str_split() function splits a string into an array.

Syntax length represents the number of each string

str_split(string,length) The default length is 1. If the above is str_split($str,2) the result is Array ([0] = > 12 [1] => 34)

If $str='1 2 3 4' then use the explode() function explode(' ',$str) to separate by spaces

If it is the content of an article, the interception method is based on the number of characters: use the strlen() function and substr() string interception function to implement the function of PHP splitting strings, such as:

<ol class="dp-xml">
<li class="alt"><span><span class="tag"><</span><span> ?php $</span><span class="attribute">len</span><span>=</span><span class="attribute-value">strlen</span><span>($row['game_detail']);  </span></span></li><li><span>//获取这个字符串的长度；   </span></li><li class="alt"><span>if($len</span><span class="tag">></span><span>102)   </span></span></li>
<li><span>//判断字符串如果大于102就输出102个字符串。   </span></li>
<li class="alt">
<span>{ echo $</span><span class="attribute">s</span><span>=</span><span class="attribute-value">substr</span><span>($row['game_detail'],<br>0,102); echo '...';   </span>
</li>
<li><span>}  </span></li>
<li class="alt"><span>else{ echo $row["game_detail"];   </span></li>
<li><span>//否则就输出全部；   </span></li>
<li class="alt"><span>}   </span></li>
<li>
<span class="tag">?></span><span> </span>
</li>
</ol>

That is, make a judgment before outputting. . strlen (string name). . substr(String, 0, 102) The range to split 0-103. The above are all the methods of splitting strings in PHP. I hope you can master them.
