With the development of the times, our development technology has also been updated. PHP is still relatively commonly used, so I studied PHP array conversion to string, and I will share it with you here. I hope it will help Useful to everyone.

It is often necessary to use PHP to process strings. PHP's built-in character functions provide very powerful functions and can basically complete most character processing operations. For example, use the str_split function to convert a character into an array, the implode function to convert a PHP array into a string, the strpos function to find another character within a character, the substr function to obtain certain characters in a character, the strlen function to obtain the character length, etc. . These are the most basic knowledge of PHP, which is convenient for daily work. I have made some summary of this function for reference only.

1, how to convert a character into an array
Solution: str_split() function
The example is as follows:

<ol class="dp-xml">
<li class="alt"><span><span>$</span><span class="attribute"><font color="#ff0000">biuuu</font></span><span> = </span><span class="attribute-value"><font color="#0000ff">'www.biuuu.com'</font></span><span>;  </span></span></li>
<li class=""><span>print_r(str_split($biuuu))  </span></li>
</ol>

Output result:

<ol class="dp-xml">
<li class="alt"><span><span>Array  </span></span></li>
<li class=""><span>(  </span></li>
<li class="alt">
<span>[0] =</span><span class="tag"><strong><font color="#006699">></font></strong></span><span> b  </span>
</li>
<li class="">
<span>[1] =</span><span class="tag"><strong><font color="#006699">></font></strong></span><span> i  </span>
</li>
<li class="alt">
<span>[2] =</span><span class="tag"><strong><font color="#006699">></font></strong></span><span> u  </span>
</li>
<li class="">
<span>[3] =</span><span class="tag"><strong><font color="#006699">></font></strong></span><span> u  </span>
</li>
<li class="alt">
<span>[4] =</span><span class="tag"><strong><font color="#006699">></font></strong></span><span> u  </span>
</li>
<li class=""><span>) </span></li>
</ol>

2. How to convert a php array to a string
Solution: implode() function
The example is as follows:

<ol class="dp-xml">
<li class="alt"><span><span>$</span><span class="attribute"><font color="#ff0000">biuuu</font></span><span> = </span><span class="attribute-value"><font color="#0000ff">array</font></span><span>('b','i','u','u','u');  </span></span></li>
<li class=""><span>print_r(implode('',$biuuu)); </span></li>
</ol>

Copy after login

Output result biiuu

3, how to find another character
in one character Solution: strpos or strstr
Example is as follows:

<ol class="dp-xml">
<li class="alt"><span><span>$</span><span class="attribute"><font color="#ff0000">biuuu</font></span><span> = </span><span class="attribute-value"><font color="#0000ff">'this is my website biuuu.com'</font></span><span>;  </span></span></li>
<li class="">
<span>$</span><span class="attribute"><font color="#ff0000">search</font></span><span> = </span><span class="attribute-value"><font color="#0000ff">'biuuu'</font></span><span>;  </span>
</li>
<li class="alt"><span>print_r(strpos($biuuu,$search)); </span></li>
</ol>

Copy after login

Output result: 19

4, how to get certain characters in the characters
Solution: substr() function
Example is as follows:

<ol class="dp-xml">
<li class="alt"><span><span>$</span><span class="attribute"><font color="#ff0000">biuuu</font></span><span> = </span><span class="attribute-value"><font color="#0000ff">'this is my website biuuu.com'</font></span><span>;  </span></span></li>
<li class=""><span>print_r(substr($biuuu,19)); </span></li>
</ol>

Copy after login

Output result: biuuu.com

5, how to get the character length
Solution: strlen() function
The example is as follows:

<ol class="dp-xml">
<li class="alt"><span><span>$</span><span class="attribute"><font color="#ff0000">biuuu</font></span><span> = </span><span class="attribute-value"><font color="#0000ff">'this is my website biuuu.com'</font></span><span>;  </span></span></li>
<li class=""><span>print_r(strlen($biuuu)); </span></li>
</ol>

Copy after login

Output result 28

The above PHP character processing functions str_split, implode, strpos, substr and strlen are often used in actual development. I hope they will be helpful to everyone.
