blocks|key|2849233|text|我认为substr()运行得太慢了。最好的方法是：|type|unstyled|depth|inlineStyleRanges|offset|length|style|CODE|entityRanges|data|2849234|return+substr($string,+0,+$beginningPos)+.+

<p>I think <code>substr()</code> works too slow. The best way is:</p>

<pre><code>return substr($string, 0, $beginningPos) .

<p>I'm interested in <code>function delete_all_between($char1, $char2, $string)</code>
that will search given $string for $char1 and $char2 and, if such has been found, clear $string from substring between these two characters, <strong>including</strong> $char1 and $char2 itself.</p>

<p>Example:</p>

<pre><code>$string = 'Some valid and &lt;script&gt;some invalid&lt;/script&gt; text!';

<p>Now, $string should contain just </p>

<pre><code>'Some valid and  text'; //note two spaces between 'and  text'
</code></pre>

<p>Does someone have quick solution?</p>


PHP function to delete all between certain character(s) in string

我对function delete_all_between($char1, $char2, $string)很感兴趣，它会在给定的$string中搜索$char1和$char2，如果找到了，则从这两个字符之间的子字符串中清除$string，包括 $char1和$char2本身。示例：$string = 'Some valid and <script>some invalid</script> te
