我正在通过 JSON 提取 Twitter 用户的个人资料图片。为此，我的代码是：

$x->profile_image_url

that returns the url of the profile image. The format of the url may be "..xyz_normal.jpg"or "..xyz_normal.png"or "..xyz_normal.jpeg"or "..xyz_normal.gif"etc.

返回个人资料图片的网址。url 的格式可以是"..xyz_normal.jpg"or"..xyz_normal.png"或"..xyz_normal.jpeg"or"..xyz_normal.gif"等。

Now I want to delete the "_normal" part from every url that I receive. How can I achieve this in php? I'm tired of trying it. Please help.

现在我想从我收到的每个 url 中删除“_normal”部分。我怎样才能在 php 中实现这一点？我厌倦了尝试。请帮忙。

Php str_replace.

php str_replace。

str_replace('_normal', '', $var)

What this does is to replace '_normal' with '' (nothing) in the variable $var. Or take a look at preg_replaceif you need the power of regular expressions.

这样做是将变量 $var 中的 '_normal' 替换为 ''（无）。或者，如果您需要正则表达式的强大功能，请查看preg_replace。

The str_replace() function replaces some characters with some other characters in a string.

str_replace() 函数用字符串中的一些其他字符替换一些字符。

try something like this:

尝试这样的事情：

$x->str_replace("_normal","",$x)

$s = 'Posted On jan 3rd By Some Dude';


echo strstr($s, 'By', true);

This is to remove particular string from a string.

这是从字符串中删除特定字符串。

The result will be like this

结果会是这样

 'Posted On jan 3rd'

Multi replace

多重替换

$a = array('one','two','three');
$var = "one_1 two_2 three_3";
str_replace($a, '',$var);

The str_ireplace() function does the same job but ignoring the case

str_ireplace() 函数执行相同的工作，但忽略大小写

like the following

像下面这样

<?php
echo str_ireplace("World","Peter","Hello world!");
?>

output : Hello Peter!

输出：你好彼得！
