[php] Tips on using str_replace to replace strings in logarithms

<code><span>$configData</span>=<span>array</span>(
    <span>'1'</span>=><span>'11111111000111111'</span>,
    <span>'3'</span>=><span>'22222222000222222'</span>,

<span>foreach</span>(<span>$configData</span><span>as</span><span>$key</span>=>&<span>$val</span>){

var_dump(<span>$configData</span>);</code>

').addClass('pre-numbering').hide(); $(this).addClass('has-numbering').parent().append($numbering); for (i = 1; i ').text(i)); }; $numbering.fadeIn(1700); }); });

The above introduces [php] the technique of using str_replace to replace strings in logarithms, including the relevant content. I hope it will be helpful to friends who are interested in PHP tutorials.
