在PHP中使用preg_Replace（）函数时出现问题[重复]

Question

This question already has an answer here:

• PHP regular expressions: No ending delimiter '^' found in 3 answers

I have used the preg_Replace function in CorePHP as follows:

$d [] = preg_Replace("^0", "", $a);

But I'm getting the following error as:

Warning: preg_replace(): No ending delimiter '^'

What does the No ending delimiter mean? What am I missing here?

You need to slightly change your syntax to one of the following two options:

$d[] = preg_replace("/^0/", "", $a);

or

$d[] = preg_replace("(^0)", "", $a);
